Abstract: The purpose of this paper is to examine the degree of the exchange rate pass-through (ERPT) to the consumer price index (CPI) at both aggregated and disaggregated levels in Vietnam. Updated data of the nominal effective exchange rate (NEER) and bilateral exchange rate (BiER) have been utilized in this study for the comparison purposes. Advanced time-series approaches such as a structural vector autoregressive framework, structural impulse response functions (SIRFs), and structural forecast-error variance decomposition (SFEVD) are utilized in this paper. Empirical findings from this paper present an incomplete degree of the ERPT to the aggregated CPI. The ERPT based on the BiER is observed to have substantially larger magnitude than the NEER-based pass-through. For the disaggregated level, the degree of the ERPT varies considerably across sub-components of the CPI, with a higher magnitude of the ERPT elasticity being found from the BiER estimations. The index of housing and construction materials has the largest ERPT based on the BiER, followed by the food and foodstuffs (1.00 and 0.56, respectively). The macroeconomic and financial environments as well as an economic integration into the global market may be the main causes of a higher ERPT in Vietnam in comparison with other ASEAN countries. The significant and incomplete pass-through of the exchange rate in Vietnam can affect firms’ and households’ budget planning, savings and profits. This finding generally implies that the cost of devaluation of the domestic currency affects the society as the whole in terms of welfare. The State Bank of Vietnam should carefully consider the overall effect of welfares when formulating and implementing strategies of currency devaluation. In addition, the Vietnamese economy becomes more sensitive to external vulnerabilities via changes of the exchange rate during an increasingly economic integration into the global market. In order to maintain inflation stability, it is vitally important to reduce the impact of exchange rate movements on the domestic prices, both aggregated and disaggregated levels, by pursuing either monetary policy credibility or inflation targeting. Previous studies on the ERPT literature in the Asia region or for emerging countries focus mainly on the aggregated data of the CPI. Previous studies were conducted before the global financial crisis in 2008/2009. The current paper is the first of its kind to examine the pass-through from exchange rates to consumer prices in Vietnam using both aggregated and disaggregated data.

Abstract: This study is conducted to examine the effect on income inequality of government spending on education across 63 provinces in Vietnam. The generalized method of moments (GMM) regression technique is used to address potential endogeneity in the model caused by income inequality and inequality in government spending on education. Income inequality is proxied by both the Gini coefficient and the Theil index. Inequality in government spending on education in Vietnam is estimated using a novel entropic approach, which decomposes the inequality into two components: “within-province” inequality and “between-province” inequality. Data for the period from 2010 to 2016 are used. Our empirical findings are summarized as follows. First, “within-province” inequality accounts for a substantial portion of inequality in government spending on education. This means that although the Vietnamese national government has done well in terms of allocating spending on education across 63 provinces, inequality in education spending appears across districts within provinces. Second, both total inequality of government spending on education and its two components are positively associated with income inequality across provinces. As such, reducing differences in government spending on education across provinces and across districts within provinces is an effective mechanism for reducing income inequality across provinces and across districts within provinces in Vietnam.

Abstract: For the past two decades, intellectual capital has played an increasingly important role in firm performance around the world. However, the importance of intellectual capital in Vietnam, and especially in the banking sector, has largely been ignored in the literature. This study is the first to examine the effect of intellectual capital on bank performance in Vietnam. In this paper, intellectual capital is decomposed into three components: (1) capital employed efficiency, (2) human capital efficiency and (3) structural capital efficiency. The paper uses an unbalanced panel dataset on 14 listed banks in Vietnam for the period 2009–2018 for which required data are available, with the generalized method of moments. The findings indicate that intellectual capital contributes significantly and positively to bank performance in Vietnam. In addition, bank performance is driven primarily by capital employed efficiency. Although human capital efficiency appears to contribute positively to bank performance, the effect on bank performance appears to be marginal. The literature review indicates that the effect of intellectual capital on bank performance is mixed. This effect can be positive or negative or even show a U -shaped relationship. The effects of intellectual capital on firm performance are not consistent, depending on factors such as the quantitative technique and s le used. As such, this paper extends analysis of Vietnam to cover the 10-year period from 2009 to 2018. The literature review reveals that the contribution of intellectual capital to bank performance has largely been ignored in the context of Vietnam. Studies have been conducted on the Gulf countries, such as Buallay et al. (2020). However, because the context in Vietnam differs from that of the Gulf countries, their experience might not be relevant to Vietnam. Vietnam is an emerging market in Southeast Asia, whereas Gulf countries have high income levels. So, it is necessary to examine direct evidence on Vietnam.

Abstract: The link between export performance and exchange rate policy has been attracting attention from policymakers, academics, and practitioners for some time, particularly for emerging countries. It has been recently claimed that implementing a policy that devalues the currency in Vietnam is an important factor for enhancing its export performance. However, it is also argued that such a policy could result in the harmful consequence of exchange rate volatility. This study analyzes the link between exchange rate devaluation, volatility, and export performance. The analysis focuses on the manufacturing sector and 10 of its subsectors that were engaged in the export of goods between Vietnam and 26 key export partners during the 2000–2015 period. Potential factors that could affect this relationship, such as the global financial crisis, Vietnam’s participation in the World Trade Organization, or even the export partners’ geographic structures, are also accounted for in the model. The findings confirm that a strategy that depreciates Vietnam’s currency appears to enhance manufacturing exports in the short run, whereas the resulting exchange rate volatility has clear negative effects in the long run. The impact of exchange rate volatility on manufacturing subsectors depends on two factors, namely, (i) the type of export and (ii) the export destination. Policy implications emerging from these conclusions are presented.

Abstract: Financial integration has greatly contributed to economic growth and development around the globe, in particular for developing countries. However, this process of financial integration has also provided threats in the form of instability which threaten the progress of economic growth and development. The objective of this study is to examine a set of indicators which are valid and indicative of financial instability in the case of developing countries. A panel data of 17 developing countries during the period 2000–2017 is utilized. The credit growth is used as a proxy of financial instability. Standard methods such as the pooled OLS, fixed effect model and random effect model are considered to ensure robustness. Empirical findings from this study indicate that the key determinants of financial instability in developing countries including Vietnam include the GDP growth rate, inflation rate, the growth rate of base money, the change in foreign exchange reserves, lending interest rate, returns in the stock market and the return on equity ratio of the banking sector. Findings from this study appear to support the views of Post-Keynesians in relation to the mechanism leading to financial instability, in particular for developing markets.

Abstract: Fiscal decentralisation has attracted great attention from governments, practitioners, and international institutions with the aims of enhancing economic growth in the last 5 decades. However, satisfactorily measuring the degree of fiscal decentralisation across countries has appeared to be problematic. In addition, the link between fiscal decentralisation and economic growth across provinces has largely been ignored, in particular for emerging markets such as Vietnam. As such, this study is conducted to determine the extent of fiscal decentralisation and to assess its impact on economic growth based on data from all 63 provinces of Vietnam in the period after the 2008 financial crisis. Instead of using traditional measures of fiscal decentralisation, the study uses the Fiscal Decentralisation Index (FDI) together with the two most important and inseparable components of the index, those being (i) the Fiscal Importance (FI) and (ii) the Fiscal Autonomy (FA). The Difference Generalised Method of Moments (DGMM) is utilised to correct for the potential problem of endogeneity between fiscal decentralisation and economic growth. Results show that the two indicators (FI and FDI) have a negative impact while FA has a positive impact on economic growth across provinces. On the ground of these empirical findings, implications for specific policies have emerged for Vietnam and other emerging markets on the extent of fiscal decentralisation, and its major determinants, which positively support economic growth in the future.

Abstract: The members of the Association of Southeast Asian Nations (ASEAN) have made several attempts to adopt renewable energy targets given the economic, energy-related, environmental challenges faced by the governments, policy makers, and stakeholders. However, previous studies have focused limited attention on the role of renewable energy when testing the dynamic link between CO2 emissions, energy consumption and renewable energy consumption. As such, this study is conducted to test a common hypothesis regarding a long-run environmental Kuznets curve (EKC). The paper also investigates the causal link between carbon dioxide (CO2) emissions, energy consumption, renewable energy, population growth, and economic growth for countries in the region. Using various time-series econometrics approaches, our analysis covers five ASEAN members (including Indonesia, Myanmar, Malaysia, the Philippines, and Thailand) for the 1971–2014 period where required data are available. Our results reveal no long-run relationship among the variables of interest in the Philippines and Thailand, but a relationship does exist in Indonesia, Myanmar, and Malaysia. The EKC hypothesis is observed in Myanmar but not in Indonesia and Malaysia. Also, Granger causality among these important variables varies considerably across the selected countries. No Granger causality among carbon emissions, energy consumption, and renewable energy consumption is reported in Malaysia, the Philippines, and Thailand. Indonesia experiences a unidirectional causal effect from economic growth to renewable energy consumption in both short and long run and from economic growth to CO2 emissions and energy consumption. Interestingly, only Myanmar has a unidirectional effect from GDP growth, energy consumption, and population to the adoption of renewable energy. Policy implications have emerged based on the findings achieved from this study for each country in the ASEAN region.

Abstract: Stability indicators are essential to banks in order to identify instability caused by adverse economic circumstances or increasing risks such as customer defaults. This paper develops a novel comprehensive stability indicator (CSI) that can readily be used by in idual banks, or by regulators to benchmark financial health across banks. The CSI incorporates the three key risk factors of Creditworthiness, Conditions and Capital (3Cs), using a traffic light system (green, orange and red) to classify bank risk. The CSI achieves similar outcomes in ranking the risk of 20 US banks to the much more complex US Federal Reserve Dodd–Frank stress tests.

Abstract: Previous empirical studies have generally considered biofuel as a main factor in changes in the relationship between oil and agricultural prices because these changes happened after U.S. biofuel policies were implemented. However, it has been argued that other economic factors can trigger the correlation of these two markets. This study was conducted to examine the transmission mechanisms that influence the relationship between oil and agricultural prices. This paper used the interacted panel vector autoregressive framework, which allowed us to investigate the effect of biofuel production under different regimes of exchange rates and global economic activities. The responses of agricultural prices to oil prices at different levels of biofuel production, global economic activity, and exchange rates were examined in this paper. Data on prices for 10 agricultural commodities—barley, beans, corn, cotton, oats, rice, sorghum, soybean, sunflower, and wheat—from January 2000 to May 2019, were used in this study. Our findings indicate that oil prices can affect agricultural prices through biofuel and exchange rates. Moreover, the effect of biofuel depends on the level of global economic activity and exchange rates. We offer some policy implications on the basis of our findings in this study.

Abstract: This paper investigates the geopolitical risk spillovers among BRICS countries during the 1985–2022 period. We adopt the novel quantile frequency connectedness approach, which allows us to examine the risk transmission by frequency and quantile. The geopolitical risks spread more intensely among BRICS countries during extreme circumstances. The long‐term geopolitical risk spillovers are the main contributors to the overall spillovers. Additionally, we note that significant increases in spillovers are associated with remarkable political events. Russia is the most dominant country and the largest short‐term and long‐term geopolitical risk transmitter to other BRICS members during the research period.

Abstract: This study revisits the energy-growth-environment nexus in the member countries of the Organization for Economic Cooperation and Development (OECD) by examining the role of trade openness, financial development, and urbanization. The cross-sectional augmented distributed lag (CS-ARDL) approach is employed to address the presence of slope homoskedasticity and cross-sectional dependence in the data set. Our empirical findings fail to confirm the validity of the environmental Kuznets curve (EKC) hypothesis for emissions of carbon dioxide (CO 2 ) during the period researched. CO 2 emissions have bidirectional causality with income, the share of renewable energy, and the share of nonrenewable energy. Trade openness, financial development, and urbanization play different roles in the energy-growth-environment nexus. Whereas trade openness increases CO 2 emissions, financial development reduces consumption of renewable energy. Urbanization plays a limited role in this nexus. These findings lead to some policy implications. The close relationship between economic growth, CO 2 emissions, and energy consumption is highlighted, which suggests that a policy targeting one component needs to consider the impacts on the other components.

Abstract: Financial development has been considered an efficient and effective mechanism for the sustainable economic growth and development of emerging markets in past decades. However, various concerns have emerged in relation to the influences of financial sector development on income inequality. It is the claim of this paper that findings from the current literature are incomplete. This is because various proxies have been utilized inconsistently for both financial development and income inequality in previous empirical studies. This study extends the current literature on this important finance–inequality nexus by examining a s le of 21 emerging countries for the period of 1961–2017. Various estimation techniques were employed with the aim of ensuring robust findings. Findings from this paper confirm the existence of an inverted U-curve relationship between financial development and income inequality, implying that income inequality may rise at the early stage of financial development and fall after a certain level is achieved. Policy implications have emerged from the findings of this study.

Abstract: Financial integration in the Association of Southeast Asian Nations (ASEAN) region is a key focus of the ASEAN Economic Community. Whereas many studies focus on modelling corporate default, this paper identifies early warning indicators of financial distress before a default, using multiple discriminant analysis (MDA) models with a s le of listed and delisted companies in the ASEAN region. The analysis examines 720 companies in 10 different industries across six ASEAN countries from 1997 to 2016. The study constructs in idual models for each country as well as an overall model for the entire region, using both in‐s le and out‐of‐s le approaches. This overall model could be useful for an integrated banking system. To ensure robustness, the study also separately examines the predictive performance of the MDA models across different economic crises: the Asian financial crisis (AFC) from 1997 to 2000, the global financial crisis (GFC) from 2007 to 2009 and their pre‐ and post‐crisis periods. We find that profitability ratios are the best indicators of financial distress in the ASEAN region, followed by liquidity and leverage ratios. In addition, our findings reveal common indicators that can be used to predict financial distress across ASEAN countries. The single model performs reasonably well in predicting financial distress 1 year ahead. In addition, the model is extended to incorporate a market‐based indicator into the MDA models, the distance to default. However, the inclusion of this indicator does not significantly improve the accuracy of the models in predicting financial distress at listed firms in the ASEAN region.

Abstract: The energy–environment–growth nexus has been examined for the Association of Southeast Asian Nations (ASEAN) region, mainly using time series data. However, the important role of renewable energy and population has largely been ignored in previous studies. As such, this study is conducted to investigate a causal link between renewable energy usage, population, carbon dioxide emissions, and economic growth. In addition, a relatively new and advanced panel vector autoregressive model and the Granger non-causality test for heterogeneous panels are utilized with a s le of seven ASEAN countries for almost three decades since 1990. Key findings from this paper are as follows. First, renewable energy usage responds to population growth and leads to carbon dioxide (CO 2 ) emissions. Second, economic growth and renewable energy usage explain a substantial proportion of the change in energy consumption. Third, a bidirectional Granger causality does exist in each pair among energy consumption, economic growth and CO 2 emissions. We argue that moderating population growth and extending renewable energy usage are vital to achieving sustainable economic growth in the ASEAN region.

Abstract: A contribution of foreign direct investment to economic growth is possibly one of the widely examined topics in academic research in the last five decades. However, few studies have examined both the short run and long run impacts of this effect concurrently for developing and emerging markets, in particular during the period of economic turmoil that includes the global financial crisis. As such, this paper examines and provides additional and relevant quantitative evidence on the impact of foreign direct investment (FDI) on economic growth, both in the short run and the long run in developing countries of the lower-middle-income group in 2000–2014. Various econometric methods are employed such as the panel-based unit root test, Johansen cointegration test, Vector Error Correction Model (VECM), and Fully Modified OLS (FMOLS) to ensure the robustness of the findings. The results of this study show that FDI helps stimulate economic growth in the long run, although it has a negative impact in the short run for the countries in this study. Other macroeconomic factors also play an important role in explaining economic growth in these countries. Money supply has a positive effect on growth in the short run while total credit for private sector has a negative effect. In addition, long-run economic growth is driven by money supply, human capital, total domestic investment, and domestic credit for the private sector. Based on these results, recommendations for the governments of these countries have been developed.

Abstract: This paper examines the effects of three distinct groups of uncertainties on market return and volatility in the Asia-Pacific countries, including (i) the country-specific and US geopolitical risks (ii) the US economic policy uncertainty and (iii) the US stock market volatility (using the VIX and SKEW indices). Our s le includes 11 Asia-Pacific countries for the 1985–2022 period. We employ the nonlinear autoregressive distributed lag approach (ARDL) estimation technique to capture the asymmetric effects of uncertainties on market return and volatility, which are documented in the literature. Some findings are documented as follows. First, we find that US uncertainty indices, including US geopolitical risk, US economic policy uncertainty, and US VIX, significantly impact Asia-Pacific stock markets, while the impacts of domestic geopolitical risk and the US skewness index (SKEW) are relatively weak. Second, Asia-Pacific stock markets tend to overreact to uncertainty shocks stemming from US economic policy uncertainty and US geopolitical risk. Third, US economic policy uncertainty has more significant effects than the US geopolitical risk. Finally, our research documents that Asia-Pacific stock markets react heterogeneously to good and bad news from US VIX. Specifically, an increase in US VIX (bad news) has a stronger impact than a decrease in US VIX (good news). Policy implications have emerged based on the findings of this study.

Abstract: This study examines the relative systematic risks of 10 industries in China and ASEAN-3, including Malaysia, Singapore, and Thailand. We use four different approaches (ordinary least squares, least absolute deviations, MM-estimator and Theil–Sen estimator) and the weekly data from 2004 to 2016 to determine the sectoral systematic risk. The data are also ided into four sub-periods: the pre-crisis, crisis, post-crisis and normal periods. We find that the rankings of systematic risk, and the risk–return framework, for 10 industries vary from one country to another. The pairwise correlation analysis shows that significant correlation of sectoral ranks between estimation methods is found in China and Thailand, but not in Malaysia and Singapore. However, no correlations of industry rankings between China and ASEAN-3 countries for all the estimation methods for the full research periods and sub-periods are found. The sub-periods analysis also suggests that the rankings of systematic risk for industries in four countries across different economic periods are unstable.

Abstract: While spillover across equity markets has been extensively investigated, volatility spillover across sectors has largely been under-examined in the current literature. This paper estimates the sectoral volatility using the ARMA-GARCH model and its spillover across Australian sectors on the VAR framework during the 2010–2021 period. We then identify breakpoints in market volatility during the Covid-19 pandemic using a wavelet methodology. We find that volatility spillover across Australian sectors is very significant at 60 per cent from 2010 to 2019, reaching 90 per cent during the Covid-19 pandemic in 2020. The spillover then reverts to its pre-pandemic level in 2021. Consumer Staples and Industrials are the significant risk transmitters, whereas Financials and Real estates are the most significant risk absorbers. Our findings also indicate that Real Estate , Health Care , and Financials record the most significant increase in volatility of more than 300 per cent. Policy implications regarding risk management across Australian sectors have emerged, particularly during extreme events such as the pandemic.

Abstract: Asian countries have emerged as a new force in the global economy for the past three decades. However, these Asian countries have experienced fundamental problems arising from migration and unemployment. While the effects of migration on unemployment have been extensively investigated for the EU and OECD countries, these effects in the context of the Asian nations have largely been under-examined. This paper investigates the impacts of migration on unemployment in 47 Asian countries for the 1990–2020 period. Various estimation techniques are used in this study, including fixed-effects and random-effects models, as well as generalized least squares and generalized method of moments (GMM). The empirical findings show that migration reduces unemployment in Asian countries when all 47 countries are jointly considered. However, when countries are separated into different groups based on income levels, migration increases unemployment in low-income and low-middle-income countries such as India, Indonesia, the Philippines, and Vietnam. Economic growth is also shown to reduce unemployment in Asian countries, regardless of the estimation techniques. Policy implications have emerged based on our analysis, including a major reform in education for low-income and low–middle-income countries to ensure that workers in these countries are ready for jobs when facing a flow of migration workers who migrate for a better economic outcome.

Abstract: National intellectual capital is generally considered a strategic advantage for national competitiveness. However, the measurement of intellectual capital across countries for comparison purposes appears to receive little attention. This study aims to use a new index of national intellectual capital (INIC) to examine the relationship between national intellectual capital and national competitiveness. This paper uses the INIC, developed by Vo and Tran (2021), to measure, compare and contrast differences in the level of national intellectual capital across 104 countries. INIC comprises the most crucial intellectual capital components: human capital, structural capital and relational capital. Various economic and social indicators are used as the proxies for these components of intellectual capital. Principal component analysis is used to derive INIC. The results indicate that during the study period the level of national intellectual capital gradually increased. Europe has attained the highest level of national intellectual capital, whereas Africa has achieved the lowest level. This study’s findings confirm a close relationship between the national intellectual capital level and the national income level. Among the ten biggest countries, the USA achieved the highest national intellectual capital level, and China has significantly improved its cumulative level. Finland achieved the highest level of national intellectual capital in the world. National intellectual capital enhances a country’s competitiveness. Findings in this study shed light on an international comparison of intellectual capital across countries and understanding how national intellectual capital contributes to and improves national competitiveness. Policymakers can consider and use these findings to support the accumulation of national intellectual capital and boost national competitive advantage, especially low-income countries and emerging markets. To the best of the authors’ knowledge, this is the first study to estimate a degree of national intellectual capital around the world and examine its impact on national competitiveness based on publicly available data.

Abstract: Intellectual capital, corporate governance (CG) and corporate social responsibility (CSR) are generally considered three essential pillars to enhance firms’ performance in the developed world. However, in developing countries such as Vietnam, these pillars have not received sufficient attention from practitioners. In addition, this study aims to investigate the interrelationship between these three essential pillars and their combined effects, in the Vietnamese context. This study uses data collected from the annual reports of the largest listed banks in Vietnam from 2011 to 2018. Intellectual capital is measured using a modified value-added intellectual coefficient model. CG is proxied by board remuneration. This study measures CSR using the ratio between charitable contributions and profit before tax. In addition, this study uses the generalized method of moments to overcome several econometric problems exhibited in previous empirical studies. Results indicate that CG and CSR have a positive impact on intellectual capital. Intellectual capital plays a moderating role in the relationship between CG and CSR. Moreover, CG and intellectual capital in the previous year significantly affect CG in the current year. Based on the findings from this study, policy implications have emerged for bank executives and policymakers in formulating and implementing policy about the balance between intellectual capital accumulation, CG and CSR. To the best of the authors’ knowledge, this is the first empirical study conducted to examine the interrelationship between intellectual capital, CG and CSR and their combined effects in emerging countries such as Vietnam.

Abstract: Financial distress is generally considered the most severe consequence for firms with poor financial performance. The emergence of the Covid-19 pandemic has adversely impacted the global business system and exacerbated the number of financially distressed firms in many countries. Only firms with strong financial fundamentals can survive extreme events such as the Covid-19 pandemic and the ongoing Russia-Ukraine conflict. Vietnam is no exception. However, studies examining financial distress using accounting-based indicators, particularly at the industry level, have largely been ignored in the Vietnamese context, particularly with the emergence of the Covid-19 pandemic. This study, therefore, comprehensively examines financial distress for 500 Vietnamese listed firms during the 2012–2021 period. Our study uses interest coverage and times-interest-earned ratios to proxy a firm’s financial distress. First, our findings confirm the validity of Altman’s Z”- score model in Vietnam only when the interest coverage ratio is used as a proxy for financial distress. Second, our empirical findings indicate that only four financial ratios, including EBIT/Total Assets , Net Income/Total Assets , Total Liabilities/Total Assets , and Total Equity/Total Liabilities , can be used in predicting financial distress in Vietnam. Third, our analysis at the industry level indicates that the "Construction & Real Estates" industry, a significant contributor to the national economy, exhibits the most significant risk exposure, particularly during the Covid-19 pandemic. Policy implications have emerged based on the findings from this study.

Abstract: Energy commodity prices are inherently volatile, since they are determined by the volatile global demand and supply of fossil fuel extractions, which in the long-run will affect the observed climate patterns. Measuring the risk associated with energy price changes, therefore, ultimately provides us with an important tool to study the economic drivers of climate changes. This study examines the potential use of long-memory estimation methods in capturing such risk. In particular, we are interested in investigating the energy markets’ efficiency at the aggregated level, using a novel wavelet-based maximum likelihood estimator (waveMLE). We first compare the performance of various conventional estimators with this new method. Our simulated results show that waveMLE in general outperforms these previously well-established estimators. Additionally, we document that while energy returns realizations follow a white-noise and are generally independent, volatility processes exhibits a certain degree of long-range dependence.

Abstract: The Vietnamese government introduced a change in the minimum tick size for stock trading on 12 September 2016 to improve market quality and reduce trade execution costs. The intended effects of this policy have not been widely investigated in an emerging market such as Vietnam. We use data on trade and quote intraday of all stocks listed on the Ho Chi Minh Stock Exchange for the periods before and after the event, with a one-week break from 12/9/2016 to 18/9/2016, for the market to adapt to the new tick size policy. Findings from this paper confirm that the trading cost is reduced following the change to the smallest tick size. However, this is different for large trades executed at the stock price associated with a larger tick size. Furthermore, the findings are robust with a different s le period. These findings imply that introducing a change in tick size in Vietnam in 2016 is desirable for improving market quality. However, the differentiation of these changes in different ranges of stock prices is not necessarily effective for improving market quality and reducing trade execution costs.

Abstract: World Bank considers financial inclusion a fundamental and practical mechanism for reducing poverty and boosting prosperity in developing and emerging markets. However, the direct benefits of financial inclusion to bank performance appear to have been largely ignored in the academic literature, in particular in the emerging markets in the Asian region. Unlike previous studies, both bank and country characteristics are considered in this paper. The financial inclusion index is estimated using four sub‐indices that can be classified into two groups: the penetration and utilisation of financial products and services. Principal component analysis and dynamic generalized method of moments (GMM) are used on a s le of 1507 banks in emerging markets in Asia for the 2008–17 period. Findings indicate that, across various scenarios, financial inclusion provides a positive and significant contribution to bank performance in the Asian region. In addition, a larger distance to the bankruptcy of banks and higher national economic growth will enhance bank performance.

Abstract: Over the past three decades, China and India have attained economic power close to that of Japan and the U.S. During this period, the importance of the derivatives market within the financial market has been widely recognized. However, little supporting evidence is available on its economic effects. This paper investigates the dynamic relationship between the derivatives markets and economic development in these four large economies, which we consider together as the CIJU (China, India, Japan, and the U.S.) group. We use a Granger-causality test in the framework of a vector error correction model (VECM) to examine this causal and dynamic relation with data for the period 1998Q1 to 2017Q4. Derivative markets are found to positively contribute to economic development in the short run in the U.S., Japan, and India, but the effect disappears in the long run. In China, the derivatives market has a negative effect on economic development in the short run. However, in the long run, we observe a positive effect from the derivatives market on economic development based on two long-run estimation techniques, namely, dynamic ordinary least squares and fully modified ordinary least squares. Also, the development of derivative markets causes growth volatility in India, both in the short run and long run.

Abstract: In developed countries, banks are perceived to accumulate a higher level of intellectual capital than firms in other sectors. However, this perception has not been considered or tested in the context of an emerging market such as Vietnam, which has one of the most dynamic economies in the Asian region. This study estimates and compares the level of accumulation of intellectual capital and its four components by financial and nonfinancial firms in Vietnam. Furthermore, this study examines the relationship between intellectual capital and its components and the performance of financial and nonfinancial firms. This study uses data collected from the annual reports of 75 financial and 75 nonfinancial firms in Vietnam from 2011 to 2018. A modified value-added intellectual coefficient model is adopted to measure the level of intellectual capital at firms. Various aspects of intellectual capital are considered, including the efficiency of human capital, structural capital, capital employed and relational capital. In addition, the generalized method of moments is used to ensure the robustness of the findings. Findings in this study indicate that financial firms in Vietnam have accumulated a higher level of intellectual capital than nonfinancial firms. In addition, intellectual capital contributes positively to financial firms' performance. Three components of intellectual capital – structural capital efficiency, capital employed efficiency and relational capital efficiency – positively affect performance by financial firms. This study is limited to financial and nonfinancial firms in Vietnam. Empirical studies in the future should incorporate the efficiency aspects of these types of firms because different industries might have different characteristics, in particular, their current efficiency level, which might cause differences in relation to the accumulation of intellectual capital. The findings of this study provide valuable evidence and implications for executives and policymakers in creating, managing and enhancing intellectual capital within the Vietnamese context, in particular in the financial sector. To the best of our knowledge, this is the first empirical study conducted in the context of Vietnam, with the following two objectives: (1) to measure and compare the level of accumulation of intellectual capital by financial and nonfinancial firms in Vietnam and (2) to examine the contribution of intellectual capital and its components to the performance by financial and nonfinancial firms in Vietnam.

Abstract: The effects of government expenditure on the shadow economy have been investigated. However, the effect from a moderating factor that affects this relationship has been largely ignored in the existing literature. This paper investigates how fiscal deficit moderates the effects of government expenditure on the shadow economy for 32 Asian countries for the past two decades since 2000. The authors use various techniques, which allow cross-sectional dependence and slope homogeneity in panel data analysis, to examine this relationship in both the long run and short run. The analysis also considers the marginal effects of government expenditure on the shadow economy at different degrees of fiscal deficits. Empirical findings from this paper indicate that an increase in government expenditure and fiscal deficit will increase the shadow economy size. Interestingly, the effects of government expenditure on the shadow economy will intensify with a greater degree of the budget deficit. The authors also find that enhancing economic growth to improve income per capita and extending international trade appears to reduce the shadow economy in the Asian countries. The authors consider that policies targeting reducing shadow economy should follow conventional economic policies on economic growth, unemployment and inflation. To the best of the authors’ knowledge, this is the first empirical study conducted to examine the moderating role of fiscal deficit in the government expenditure–shadow economy nexus in Asian countries.

Abstract: The purpose of this paper is to evaluate and estimate market risk for the ten major industries in Vietnam. The focus of the empirical analysis is on the energy sector, which has been designated as one of the four key industries, together with services, food, and telecommunications, targeted for economic development by the Vietnam Government through to 2020. The oil and gas industry is a separate energy-related major industry, and it is evaluated separately from energy. The data set is from 2009 to 2017, which is decomposed into two distinct sub-periods after the Global Financial Crisis (GFC), namely the immediate post-GFC (2009–2011) period and the normal (2012–2017) period, in order to identify the behavior of market risk for Vietnam’s major industries. For the stock market in Vietnam, the website used in this paper provided complete and detailed data for each stock, as classified by industry. Two widely used approaches to measure and analyze risk are used in the empirical analysis, namely Value-at-Risk (VaR) and Conditional Value-at-Risk (CVaR). The empirical findings indicate that Energy and Pharmaceuticals are the least risky industries, whereas oil and gas and securities have the greatest risk. In general, there is strong empirical evidence that the four key industries display relatively low risk. For public policy, the Vietnam Government’s proactive emphasis on the targeted industries, including energy, to achieve sustainable economic growth and national economic development, seems to be working effectively. This paper presents striking empirical evidence that Vietnam’s industries have substantially improved their economic performance over the full s le, moving from relatively higher levels of market risk in the immediate post-GFC period to a lower risk environment in a normal period several years after the end of the calamitous GFC.

Abstract: Vietnam has undergone four waves of the Covid-19 pandemic in 2020 and 2021, which have posed significant market risks to various sectors. Understanding the market risk of Vietnamese sectors and its changes is important for policy implementation to support the economy after the pandemic. This study measures the sectoral market risks and examines the effects of the pandemic, policy responses and macroeconomic fundamentals on the market risks across sectors in Vietnam. We employ the Value-at-Risk (VaR) and Conditional Value-at-Risk (CVaR) techniques to measure the market risks for 24 sectors from 2012 to 2021. The market risk levels across Vietnamese sectors have changed significantly in response to the pandemic. Oil and Gas and Services sectors show the largest potential loss during the two Covid-19 waves in 2020. The Securities sector is the riskiest sector during the last two Covid-19 waves in 2021. Our results indicate that the new Covid-19 cases reported by the Government increase the market risk levels across Vietnamese sectors. On the other hand, enhancing containment and health policy and reducing economic policy uncertainty result in lower market risk across sectors. We also find that macroeconomic fundamentals such as the exchange rate and interest rate significantly affect the market risks across sectors in Vietnam.

Abstract: Income inequality in many middle-income countries has increased at an alarming level. While the time series relationship between income inequality and economic growth has been extensively investigated, the causal and dynamic link between them, particularly for the middle-income countries, has been largely ignored in the current literature. This study was conducted to fill in this gap on two different s les for the period from 1960 to 2014: (i) a full s le of 158 countries and (ii) a s le of 86 middle-income countries. The Granger causality test and a system generalized method of moments (GMM) are utilized in this study. The findings from this study indicate that causality is found from economic growth to income inequality and vice versa in both s les of countries. In addition, this study also finds that income inequality contributes negatively to the economic growth in the middle-income countries in the research period.

Abstract: Beta is considered an important measure of systematic risk which is arguably present in an emerging market. Daily data for 2200 Australian listed firms is collected for the January 2007–December 2016 period. Various portfolios are considered. Days with announcements (the a-day) related to crucial macroeconomic news are allocated into the group which is separated from the n-day (nonannouncement days) group. Findings indicate that beta is negatively related to daily expected excess returns in the announcement days in comparison with the nonannouncement days. It is the claim of this paper that portfolio formations do matter when empirical studies on asset pricing are conducted.

Abstract: Understanding the determinants of the shadow economy plays a vital role in formulating policies for economic growth and development, particularly for the Southeast Asian countries–a new economic force for a global economy. The key drivers of a shadow economy, such as institutional quality, taxation, government expenditure, are widely examined. However, the effect of national intellectual capital, which affects macroeconomic indicators, on the shadow economy has largely been ignored in the existing literature. Our paper examines this critical link and its causality relationship for eight Southeast Asian countries from 2000 to 2017. This paper uses the dynamic ordinary least squares (DOLS) and fully modified ordinary least squares (FMOLS), which allow cross-sectional dependence and slope homogeneity in panel data analysis. Empirical findings from this paper indicate that national intellectual capital impacts negatively and significantly the shadow economy size. This finding implies that enhancing national intellectual capital reduces the shadow economy size. These two forces lead to enhanced economic growth. Our Granger causality tests confirm a bi-directional relationship between national intellectual capital and the shadow economy. As a result, policies targeted to reduce the shadow economy size can now include the accumulation of national intellectual capital, particularly for Southeast Asian Countries.

Abstract: During the Covid-19 pandemic, the Vietnamese government has actively implemented various policies to achieve dual objectives: (i) to minimize the loss of life due to the infection and (ii) to support economic growth. This paper is conducted to examine the effect of the government’s containment and closure policy on the stock market quality in Vietnam. Unlike other papers, we focus exclusively on market quality during the pandemic. We find that the policies appear to positively affect the market quality, except for closing-school policy (negative effect) and international travel (no effect). We argue that the government should sustain the policies until the wide availability of the vaccine to support the stock market quality in the near future.

Abstract: In this paper, we seek to find a balanced structure of energy sources that can simultaneously achieve two essential goals: (i) the environmental (degradation) goal and (ii) the economic (growth) goal. This study combines quantitative and qualitative methods to estimate and then rank each of the energy sources (including coal, gas, oil, hydropower, and renewable energy) to achieve the above two goals. This paper uses the weighted scoring method, the most popular method in multi-criteria decision-making techniques, to combine the rankings using five energy sources and two goals from panel data of 28 countries from Organization for Economic Co-operation and Development (OECD) countries for the period 1980–2017. Techniques for estimating the mean group long-run effect, including fully modified ordinary least squares (FMOLS) and dynamic ordinary least squares (DOLS), are used. The empirical findings of this paper reveal that, in the long term, in achieving both environmental goals and economic goals, the OECD countries should consider adopting a balanced energy mix in which the following structure is preferred: (i) hydropower, (ii) renewables and (iii) fossil fuels (oil, gas, coal).

Abstract: The purpose of this paper is to examine the causal effect of intellectual capital (IC) performance on financial performance at Thai listed banks. Data are collected from 16 listed banks in Thailand for the period 1997–2016. This paper uses the value-added intellectual coefficient methodology suggested by Pulic (1998, 2004) to measure IC. This study employs a fixed-effects and random-effects model and generalized method of moments (GMM) estimator to investigate the causal effect of IC on financial performance. The results show that bank profitability is driven mainly by capital employed efficiency to make a profit. However, human capital efficiency marginally reduces bank profitability in the current period but has positive effects on future profitability. First, this study does not cover data on foreign banks, which reduces the generalizability of the results. Second, financial statements can be manipulated through accounting adjustments. Lastly, subsequent research should control for more bank characteristics, such as bank ownership, the non-performing loan ratio and R& D expenditure. To achieve higher future profitability, banks should not only manage their physical and financial capital effectively but also improve employee efficiency. This paper contributes to the literature on IC in the banking sector in emerging countries. Moreover, this paper is the first to employ the GMM method in the banking context to address possible endogeneity problems.

Abstract: While the independent effect is widely examined, the joint effect of financial development and renewable energy on energy consumption has largely been ignored in the current literature. Eleven members of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) must balance the simultaneous requirements of supporting financial development, increasing renewable energy usage, and minimizing the adverse effects of energy consumption on the environment. Unlike previous studies, the paper examines the joint and independent effects of financial development and renewable energy on energy consumption for the CPTPP countries during the 1971-2019 period using the second-generation estimator analysis. Our variables are carefully selected based on solid hypotheses and empirical studies. Our results confirm an inverted U-shaped relationship between energy consumption and economic growth. We claim that financial development affects energy consumption depending on the level of renewable energy consumption. The bidirectional causality effect between financial development, energy consumption, and economic growth is also confirmed. Robustness checks have been conducted using sub-s les based on the per capita income threshold of $39,054. Policy implications have emerged based on these findings. An increase in renewable energy consumption can help these nations achieve the dual objectives: (i) to support financial development and to enhance economic growth and (ii) to reduce an adverse effect of financial development and economic growth on the environment.

Abstract: The paper examines the relationship between the economic integration and growth nexus in Vietnam using powerful quantitative methods, specifically the Autoregressive Distributed Lag (ARDL) and the Granger causality test. The study focuses on three types of economic integration, including overall integration, financial integration and trade integration, which affected economic growth in Vietnam from 1986 to 2015. The key finding from this study is that when three types of economic integration are considered together, integration provides positive impacts on economic growth. In addition, causal relationship exists between overall integration and financial integration, and between trade integration and financial integration. As such, financial integration is absolutely important to economic growth in Vietnam. On the grounds of these findings, the Vietnamese government should carefully outline socio-economic development strategies to maintain political stability and to derive benefits from economic integration and globalization.

Abstract: Financial inclusion has generally been considered an effective mechanism to support economic growth and reduce Vietnam’s poverty for the last decade. While the importance of financial inclusion to economic growth or macroeconomic stability has been widely examined, it appears that the degree of financial inclusion across Vietnam has not attracted attention from academics and policymakers. In particular, a convergence of financial inclusion across provinces in Vietnam has never been examined. This paper is conducted to examine the static and dynamic distributions of financial inclusion across provinces in Vietnam. The latest three biennial surveys from 2014 to 2018 and a novel approach known as the dynamic kernel density function are used in this study. Our results indicate that Vietnam’s economic growth and development over the 2014–2018 period is relatively inclusive. The evidence also demonstrates that households provided with access to multiple sources of finance depend significantly on the provincial level of income. We also find that provinces located in the national key economic regions, including (i) the Northern region and (ii) the Southern region, appear to achieve a higher degree of financial inclusiveness. Our findings also confirm the catching-up from the financially disadvantaged provinces to financially advantaged provinces locating within the key economic regions. We argue that understanding the asymmetric effect of economic growth on financial inclusion will be helpful for the Vietnamese government in formulating and implementing economic policies promptly to secure the sustainable and inclusive goals of economic growth and development in the future.

Abstract: This study is conducted to examine the concerns of the foreign direct investment (FDI) causing environment degradation and also to test the validity of the traditional Environmental Kuznets Curve (EKC) in the context of emerging markets in the Asian region. Data of these countries from 1980–2016 are utilised. This study employs panel cointegration Fully Modified Ordinary Least Squares (FMOLS), which treats the endogeneity problem, and its estimators are adjusted for serial correlation. Moreover, this study also uses panel Dynamic Ordinary Least Squares (DOLS), which includes contemporaneous value, leads and, lags of the first difference of the regressors to correct endogeneity problems and serial correlations. Findings from this study indicate that the pollution heaven hypothesis and the EKC curve are generally valid in the region. In addition, FDI has a strong impact on the environment.

Abstract: A very few studies have been conducted to measure a degree of national intellectual capital for selected groups of countries. This paper is conducted to construct a new index of national intellectual capital (INIC) which is simple, quantifiable, relevant and comparable for countries around the globe. The styudy’s new INIC uses various indicators which are proxies for fundamental aspects of intellectual capital, including (1) human capital, (2) structural capital and (3) relational capital. These indicators are publicly available for many countries. The principal component analysis is utilized to derive the INIC. Various tests have also been conducted to ensure that the new index is appropriate and fit for purpose. Findings from this paper confirm that the new INIC has a strong correlation of 0.80 with an index developed by Lin et al. (2014) (the LECB index), an advanced INIC to date. The LECB index has been infrequently updated and covered selected countries due to data and information unavailability. In addition, the study’s tests indicate that a high correlation of 0.75 is observed between the study’s index and GDP per capita. The new INIC represents an advancement in relation to its simplicity, quantification, relevance and international comparison across nations. The estimates of national intellectual capital using the approach in this study will open a new strand of theoretical and empirical studies in relation to national intellectual capital and other economic and social issues of interests. This novel and innovative approach will provide policymakers with a valuable framework to formulate and implement relevant policies to enhance and improve national intellectual capital. To the best knowledge of the authors, this is the first study of its type, which is conducted to measure national intellectual capital based on publicly available data. Required data cover an extended period of years and a majority of countries. As such, an INIC will enhance transparency and feasibility for international comparison across countries.

Abstract: Information on the living conditions of widows in Vietnam is limited. Prior studies of gender gaps have identified widows as vulnerable to the risks of poverty. However, widows are only included as a sub-group in broader studies of women’s well-being. Large gaps remain in the knowledge based on the factors affecting both widows’ susceptibility to poverty and the conditions or circumstances that might minimize these risks. This paper attempts to help redress these knowledge gaps by contributing an analysis of data from the 2018 Vietnam Household Living Standard Surveys. The paper compares the likelihood of poverty for widowed and other households using probit regression. It also assesses whether widows who head up their households face different risks of poverty from those who live in other households. Finally, the paper examines the effects on the risk of poverty of a range of social, demographic and locational characteristics of widow households in Vietnam. Our results indicate that widowed households have experienced a higher probability of falling into poverty. Moreover, widow-headed households have faced more vulnerability to fresh water and housing, especially among widowed households. Policy implications have emerged based on the findings of this paper.

Abstract: In 2021, when the Covid-19 pandemic had a severe impact on the economy, a significant number of enterprises in Vietnam temporarily suspended doing business. Previous studies have focused on either model for predicting bankruptcy and financial distress or measuring market risk during extreme events. The effects of market risk and financial distress on a firm’s performance have largely been ignored in the literature, particularly in Vietnam. This study examines the effects of market risk, measured using the conditional value-at-risk technique and financial distress proxied by the interest coverage ratio (ICR) on firm performance for 500 nonfinancial listed firms in Vietnam from 2012 to 2021. We also estimate the optimal ICR for Vietnam’s listed firms. Two estimation techniques are used: dynamic panel models (two-step difference–and system–generalized method of moments) and panel threshold regression. We find that increased market risk reduces firm performance. However, a higher ICR (lower financial distress) also improves a firm’s performance. With increased market risk, the financial performance of firms with a high ICR deteriorates significantly.

Abstract: The trade agreement is generally considered an effective mechanism to encourage trading activities. However, trade activities may lead to environmental degradation because more trade is generally associated with more energy consumption. In addition, financial development with an increased flow of capital among members is required to fund trading activities. Renewable energy can be a moderating factor to balance the effects of trade activities and financial development on the economy and the environment. This paper focuses on the inter-relationship between growth-energy-finance nexus for the CPTPP members in the 1971–2020 period. While the energy-growth-environment nexus has been extensively investigated, the energy-growth-finance relationship has been largely ignored in existing literature, particularly for the CPTPP countries. Our findings can be summarized as follows. First, we find that renewable energy consumption does reduce CO 2 emission while financial development does not necessarily increase environmental degradation. Second, financial development is found to cause renewable energy usage bilaterally. Finally, when different proxies are used for financial development, a bilateral causality relationship between renewable energy usage, financial development and economic growth is confirmed. These important findings imply that the governments of the CPTPP countries should encourage renewable energy usage to achieve the dual objectives from the CPTPP trade agreement: (i) to increase trade activities and (ii) to support further financial development within the region. These two objectives together support economic growth.

Abstract: The effects of intellectual capital on firm performance have been extensively investigated. However, the important role of corporate social responsibility in moderating this intellectual capital–performance nexus has largely been neglected in the existing literature. This study uses a s le of 60 listed firms on the Ho Chi Minh Stock Exchange from 2011 to 2020 to examine the independent and joint effects of intellectual capital and corporate social responsibility on firm performance in Vietnam. The generalized method of moments is used. We find that both independent and joint effects exist. Furthermore, our results suggest that structural capital efficiency and capital employed efficiency are the two critical components of intellectual capital affecting firm performance. Interestingly, the joint effects of intellectual capital and CSR on firm performance are also confirmed in our analysis. These findings shed light on important policy implications concerning managerial policies targeting both intellectual capital and corporate social activities to improve firm performance in Vietnam.

Abstract: There has been much discussion in the literature about how central measures of equity risk such as standard deviation fail to account for extreme tail risk of equities. Similarly, parametric measures of value at risk (VaR) may also fail to account for extreme risk as they assume a normal distribution which is often not the case in practice. Nonparametric measures of extreme risk such as nonparametric VaR and conditional value at risk (CVaR) have often been found to overcome this problem by measuring actual tail risk without applying any predetermined assumptions. However, this article argues that it is not just the actual risk of equites that is important to investor choices, but also the relative (ordinal) risk of equities compared to each other. Using an applied setting of industry portfolios in a variety of Asian countries (benchmarked to the United States), over crisis and non-crisis periods, this article finds that nonparametric measures of VaR and CVaR may provide only limited new information to investors about relative risk in the portfolios examined as there is a high degree of similarity found in relative industry risk when using nonparametric metrics as compared to central or parametric measures such as standard deviation and parametric VaR.

Abstract: This Special Issue publishes high quality papers on contemporary issues in business and economics in Vietnam and other Asian emerging markets. These papers were accepted and presented at the 2019 Vietnam’s Business and Economics Research Conference (VBER2019) organized by Ho Chi Minh City Open University, Vietnam in July 2019. Emerging issues in business and economics from Vietnam and other emerging markets in the Asian region have been addressed from various angles, from economics, finance, and statistics to management science. Five out of the 14 studies in this book were conducted to investigate various issues in relation to the Asian region such as the exchange rate regime in Asia, financial inclusion, and financial development and income inequality in Asian emerging markets. Seven studies were conducted in response to emerging business and economic issues in Vietnam such as fiscal decentralization, urbanization, foreign direct investment, and corporate financial distress. Other papers even considered various relevant aspects from the United States and Europe to the Asian region including double taxation treaties and agricultural shocks to the oil price. The findings from these papers are useful for practitioners, policymakers, and academics.

Abstract: This paper aims to examine the relationship between corporate governance and intellectual capital in the context of Vietnam. In this paper, corporate governance is proxied by various characteristics, including board size, a number of independent members in the board, board remuneration, major shareholder holding more than 20 per cent of the outstanding shares and duality of the CEO. In addition, intellectual capital is measured using the modified value-added intellectual coefficient model (MVAIC). The study uses data of 45 Vietnamese listed firms during 2011-2018. The MVAIC model is used incorporating four components, namely, human capital, structural capital, capital used and relational capital. In addition, GMM regression technique is used in this paper. Empirical findings from this paper indicate that key characteristics of corporate governance, except for board remuneration, may provide a negative effect on the efficient use of intellectual capital. Intellectual capital emerges as a new field of research that has not been widely examined in emerging countries such as Vietnam. As such, there have not been many studies focusing on understanding intellectual capital and its role in the performance of enterprises. Further studies can evaluate the relationship between intellectual capital and corporate performance, capital structure, corporate value and social responsibility. This study is limited to listed companies in Vietnam because of data limitations in an emerging market. Studies in the future should extend the s le and/or compare differences between manufacturing enterprises and financial institutions, or between countries. Findings from this paper provide a valuable framework for executives, managers and policymakers in managing corporate governance and intellectual capital within the Vietnamese context. To the best of the authors’ knowledge, this is the first empirical study that has been conducted to examine the relationship between corporate governance and intellectual capital in the context of Vietnam.

Abstract: Previous studies examined the relationship between intellectual capital and a firm's performance. However, the moderating role of corporate governance—a fundamental factor leading to improved firm performance and increased intellectual capital accumulation—has largely been ignored, particularly in an emerging market such as Vietnam. As such, this study examines the moderating role of corporate governance on the intellectual capital–performance nexus in Vietnam. This study uses a s le of 45 listed firms in Vietnam from 2011 to 2018. The generalized method of moments (GMM) technique is utilized in this paper to enhance the robustness of the findings. The modified value‐added intellectual coefficient (MVAIC) model is used to measure intellectual capital. A firm's performance is proxied by both returns on assets and equity. Our results indicate that intellectual capital components such as capital employed efficiency, human capital efficiency and structural capital efficiency provide a significant and positive effect on a firm's performance. In addition, the results reveal that the inclusion of corporate governance as a moderating factor affects the relationship between intellectual capital and a firm's performance in Vietnam. Findings from this paper provide a valuable framework and implications for executives and policymakers in creating and managing intellectual capital within the Vietnamese context. Besides, improving corporate governance is critical to improving intellectual capital accumulation. To the authors' best knowledge, our literature review indicates that this is the first empirical study that examines the relationship between intellectual capital and a firm's performance using corporate governance as a moderating factor in Vietnam.

Abstract: Long-range dependency of the volatility of exchange-rate time series plays a crucial role in the evaluation of exchange-rate risks, in particular for the commodity currencies. The Australian dollar is currently holding the fifth rank in the global top 10 most frequently traded currencies. The popularity of the Aussie dollar among currency traders belongs to the so-called three G’s—Geology, Geography and Government policy. The Australian economy is largely driven by commodities. The strength of the Australian dollar is counter-cyclical relative to other currencies and ties proximately to the geographical, commercial linkage with Asia and the commodity cycle. As such, we consider that the Australian dollar presents strong characteristics of the commodity currency. In this study, we provide an examination of the Australian dollar–US dollar rates. For the period from 18:05, 7th August 2019 to 9:25, 16th September 2019 with a total of 8481 observations, a wavelet-based approach that allows for modelling long-memory characteristics of this currency pair at different trading horizons is used in our analysis. Findings from our analysis indicate that long-range dependence in volatility is observed and it is persistent across horizons. However, this long-range dependence in volatility is most prominent at the horizon longer than daily. Policy implications have emerged based on the findings of this paper in relation to the important determinant of volatility dynamics, which can be incorporated in optimal trading strategies and policy implications.

Abstract: China is a fascinating country in Asia, the second-largest economy in the world, with incredible economic growth and development in the last two decades. In addition, China has dramatically enjoyed a disciplined and successful financial integration with the region and the world in the same period. As such, it is interesting to examine a potential link between economic growth and financial integration in this most populous country. This paper was conducted to identify whether financial integration fosters Chinese economic growth. The Auto-Regressive Distributed Lags (ARDL) model is selected, utilizing the most updated data on a globalization (or integration) index. Two distinct aspects of financial integration, the de facto (proxied for economic activities) and the de jure (proxied for the Government policies leading to integration), are considered in this paper. We apply an econometric technique, using yearly aggregated data, to examine a long-term co-integration and a causal relationship between financial integration and economic growth in China. Findings from this paper indicate a long-term co-integration between financial integration de facto and economic growth in China. The bidirectional causality between financial integration and economic growth in China is also confirmed using the Granger causality test.

Abstract: The effects of temperature have largely been under-examined in climate change studies. This study examines both direct and indirect effects of temperature on environmental degradation using the s le of 103 middle-income countries from 1985 to 2019. Unlike previous studies in which a single equation approach is utilized, our study considers the simultaneous equations modelling to examine the energy-growth-environment nexus incorporating temperature and corruption. The difference and system generalized method of moments estimations for panel data are used. Empirical results from this paper confirm both the direct and indirect effects (via energy consumption) of temperature on environmental degradation. We find corruption harms economic growth in middle-income countries. The continued use of fossil fuel energy in energy consumption deteriorates environmental quality. Our findings confirm the critical role of the services sector in supporting economic growth and reducing emerging consumption, leading to increased environmental quality. Findings from our study reconfirm the vital role of renewable energy and its extended use in achieving dual objectives of supporting economic growth and improving the environmental quality in middle-income countries.

Abstract: Financial integration has played an essential role in achieving economic growth in the members of the Association of Southeast Asian Nations (ASEAN). However, its effects on economic growth in the region in the long run have been underexamined. This paper examines these effects for the ASEAN member countries. A fully modified ordinary least squares (FMOLS) estimation is used to take into account two critical econometric issues in panel data analysis, including (1) cross-sectional dependence and (2) slope heterogeneity. The dynamic ordinary least squares estimation is also used for robustness analysis. The authors use the generalized least squares estimation to examine the effects in the short run. This study’s empirical results confirm the important role of financial integration to economic growth in the ASEAN countries in the short term. However, the effects appear to disappear in the long term. The authors also find capital, labor, and human development positively contribute to economic growth in the region. International trade plays a significant role in supporting economic growth in the ASEAN in the short run. However, its effect seems to weaken in the long run. The growth effects of financial integration in the ASEAN region in the long term have largely been neglected. As such, the authors examine these effects using updated data on financial integration. The authors extend this study’s analysis by considering foreign direct investment and financial depth as the alternative proxies for financial integration. Other estimation technique is also used as the robustness check.

Abstract: The cornerstone of the capital asset pricing model (CAPM) lies with its beta. The question of whether or not beta is dead has attracted great attention from academics and practitioners in the last 50 years or so, and the debate is still ongoing. Many empirical studies have been conducted to test the validity of beta within the framework of CAPM. However, it is a claim of this paper that beta at the industry level has been largely ignored in the current literature. This study is conducted to examine if beta, proxied for a systematic risk, should be considered valid in the application of the CAPM at the industry level for Australia using daily data on 2200 stocks listed on the Australian Securities Exchange from January 2007 to 31 December 2016. Various portfolio formations are utilized in this paper. General economic conditions such as interest rate, inflation, and GDP are ex les of systematic risk. Findings from this study indicate that the selection of portfolio construction, estimation technique, and news about economic conditions significantly affects the view whether or not beta should be considered as a valid measure of systematic risk.

Abstract: The effects of environmental regulation stringency on foreign direct investment are noted in the existing literature. However, current literature appears to have ignored the feedback effects from foreign investment to environmental regulation stringency. This feedback effect plays a significant role in designing policies to attract foreign investment to support economic growth and improve environmental quality concurrently. This study examines the feedback effects from foreign investment on environmental regulation stringency using the Organisation for Economic Co‐operation and Development (OECD) newly developed Environmental Policy Stringency Index for 26 OECD countries for almost three decades since 1990. The key findings from this study to the existing literature are threefold. First, we find that foreign investment affects the environment regulation stringency via lobbying. However, when the number of legislative units in the host countries is large enough, the lobbying effect diminishes, particularly for the larger‐gross domestic product (GDP) and the higher‐per‐capita‐income OECD countries. Second, our empirical results confirm the U‐shaped relationship between manufacturing activities and the environmental regulation stringency. Third, the bilateral relationship between environmental regulation stringency and foreign investment is found, indicating that ignoring foreign investment in designing environmental policies is problematic. Finally, policy implications have emerged based on the findings from this study.

Abstract: Any critical analysis of the corporate financial distress of listed firms in international exchange would be incomplete without a serious dissection at the industry level, because of the different levels of risks concerned. This paper considers the financial distress of listed firms at the industry level in Vietnam over the last decade. Two periods are considered, namely during the Global Financial Crisis (GFC) (2007–2009) and post-GFC (2010–2017). The logit regression technique is used to estimate alternative models based on accounting and market factors. The paper also extends the analysis to include selected macroeconomic factors that are expected to affect the corporate financial distress of listed firms at the industry level in Vietnam. The empirical findings confirm that the corporate financial distress prediction model, which includes accounting factors with macroeconomic indicators, performs much better than alternative models. In addition, the evidence confirms that the GFC had a damaging impact on each sector, with the Health & Education sector demonstrating the most impressive recovery post-GFC, and the Utilities sector recording a dramatic increase in bankruptcies post-GFC.

Abstract: In his influential study, Theil (1967) developed the notion of entropy on the basis of information theory. He then advocated the use of entropy-based measure for the analysis of income inequality. In this paper, the first of its kind, we apply Theil’s notion of entropy to public finances in multi-tiered governments, in particular for a measurement of fiscal decentralisation, which is currently very crude in terms of the ratio between local government revenue and total revenue. It is the claim of this paper that such an approach of measuring fiscal decentralisation completely ignores important distributional aspects of fiscal arrangements. Findings from this paper indicate that studies on measuring various aspects of fiscal activities—such as fiscal decentralisation—should carefully take into account the dispersion of revenue (and expenditure) across regions. On that basis, the entropic approach developed in this paper is able to accommodate these dispersions across subnational governments. As an illustration for the case of Vietnam, the true degree of fiscal decentralization has effectively been decreased in comparison with estimates from other simple measurements due to the presence of substantial dispersions of revenue and expenditure from the subnational governments across 63 provinces in Vietnam.

Abstract: Tax evasion, which is typically considered an illegal activity, is a critical problem and is considered a barrier to economic growth. A review of the literature shows that tax and social security contributions, regulations, public sector services, the quality of institutions and tax compliance, play important roles in determining the degree to which firms attempt to evade taxes. Measuring tax evasion is problematic due to data requirements and inadequacies. Few tax evasion indices have been estimated but it appears that they cannot be used for international comparisons across countries. This important issue has largely been ignored in the literature, in particular for emerging markets. Consequently, this paper is conducted to develop a new tax evasion index (TEI) using the most substantial and recent data from the standardized World Bank Enterprises Survey 2006–2017. In addition, using the newly developed TEI, the paper examines the importance and contribution of information sharing and bank penetration to the degree of tax evasion in emerging markets. The paper uses a s le of 112 emerging markets from 2006–2017 and the Tobit model in estimation. The empirical findings from the paper indicate that the average TEI during the 2006–2017 period for emerging markets is 0.62, with a range of (0.25, 0.75). In addition, we find that information sharing and bank penetration negatively affect the degree of tax evasion, as proxied by the TEI, in emerging markets. The empirical results also confirm the view that large firms are considered to have adopted good tax compliance practices, while firms located in remote areas are more likely to evade taxes. Policy implications have emerged on the basis of the empirical findings from the paper.

Abstract: The value of a country's currency is often considered as the most important price in the economy. Exchange‐rate changes can significantly affect the profitability of exporters, the prices paid by consumers, as well as complicating the comparison of the economies of different countries. In this article, we illustrate the workings of the purchasing power parity (PPP) and demonstrate its practical use with cross‐country data covering the 50 years since the collapse of the Bretton Woods monetary system. We find that despite the prolonged gyrations of currency values and the multitude of trade barriers, the forces of arbitrage and resource re‐allocation are sufficient to overcome many of these distortions in the longer term. We also provide a broad survey of other prominent themes, both extant and emerging, in international economics that highlight the importance of the relationship between exchange rates and prices.

Abstract: The purpose of this study is to explore the relationship among financial development (FD), economic growth, urbanization and human capital (HC) in Vietnam. This study uses various wavelet tools, including wavelet coherence, wavelet correlation and scale-by-scale Granger causality test, to re-visit the lead–lag structure among economic growth, FD, urbanization and HC in Vietnam from 1980 to 2017. The main findings indicate that economic growth and urbanization improve HC at the medium and low frequencies, whereas FD negatively affects HC from 1989 to 2017. Furthermore, the scale-by-scale Granger causality results confirm a uni-directional causality relationship between economic growth to HC at low and high frequencies. In contrast, a bi-directional causality relationship between urbanization and HC is found in the long run. Policy implications have emerged based on the empirical results from this study. The Vietnamese Government should continue supporting economic integration, implementing investment promotion policies and focussing on foreign direct investment using green technologies. The impact of FD on HC at different time scales has largely been ignored in Vietnam. This study substantially contributes to the existing literature regarding HC and FD. This analysis is one of the earliest attempts to examine the effects of economic indicators on HC in the time-frequency analysis.
