Labor productivity growth in the Kansas Farm sector: A tripartite decomposition using a non-parametric approach
Publisher: Cambridge University Press (CUP)
Date: 12-2012
DOI: 10.1017/S1068280500001271
Abstract: We use nonparametric production function methods to decompose farm-level labor productivity growth into components attributable to efficiency change, technical change, and factor intensity. The estimation is accomplished using balanced panel data drawn from the Kansas Farm Management Association for the period 1993 to 2007. We find that labor productivity growth is primarily driven by factor intensity and technical change. Efficiency change is declining with increasing productivity growth, and technical change is not Hicks-neutral and occurs at high levels of factor intensity, suggesting that innovation is embodied in factor intensity.

Measuring efficiency of cotton cultivation in Pakistan: A restricted production frontier study
Publisher: Wiley
Date: 30-04-2014
DOI: 10.1002/JSFA.6652
Abstract: Massive groundwater pumping for irrigation has started lowering water tables rapidly in different regions of Pakistan. Declining water tables have thus prompted research efforts to improve agricultural productivity and efficiency to make efficient use of scarce water resources. This study employs a restricted stochastic production frontier to estimate the level of, and factors affecting, technical efficiency of groundwater-irrigated cotton farms in the Punjab province of Pakistan. The mean technical efficiency estimates indicate substantial technical inefficiencies among cotton growers. On average, tube-well owners and water buyers can potentially increase cotton production by 19% and 28%, respectively, without increasing the existing input level. The most influential factors affecting technical efficiency positively are the use of improved quality seed, consultation with extension field staff and farmers' perceptions concerning the availability of groundwater resources for irrigation in the future. This study proposes that adopting improved seed for new cotton varieties and providing better extension services regarding cotton production technology would help to achieve higher efficiency in cotton farming. Within the context of falling water tables, educating farmers about the actual crop water requirements and guiding them about groundwater resource availability may also help to achieve higher efficiencies. © 2014 Society of Chemical Industry.
A Forecast Combination Framework with Multi-Time Scale for Livestock Products’ Price Forecasting
Publisher: Hindawi Limited
Date: 20-10-2019
DOI: 10.1155/2019/8096206
Abstract: China’s livestock market has experienced exceptionally severe price fluctuations over the past few years. In this paper, based on the well-established idea of “forecast combination,” a forecast combination framework with different time scales is proposed to improve the forecast accuracy for livestock products. Specifically, we combine the forecasts from multi-time scale, i.e., the short-term forecast and the long-term forecast. Forecasts derived from multi-time scale introduce complementary information about the dynamics of price movements, thus increasing the ersities within the modeling process. Moreover, we investigate a total of ten combination methods with different weighting schemes, including linear and nonlinear combination. The empirical results show that (i) forecast performance can be remarkably improved with this novel combination idea, and short-term forecast model is more suitable for the products with a relatively high volatility, e.g., mutton and beef (ii) geometric mean, which provides a nonlinear combination, is the most effective one among all the combination methods and (iii) variance-based weighting scheme can yield a superior result compared to the best in idual forecast, especially for the products such as egg and beef.

Irrigation water demand and implications for groundwater pricing in Pakistan
Publisher: IWA Publishing
Date: 22-12-2016
DOI: 10.2166/WP.2015.160
Abstract: This study employs the positive mathematical programming (PMP) approach to estimate groundwater derived demand for irrigation using a cross-sectional dataset of 200 predominantly groundwater irrigated farms from the Punjab province of Pakistan. First, we find that the PMP optimal solution uses less water than what is available (being extracted) in order to make farmers allocate all the available land to different crops. Second, when water supplies are constrained farmers allocate land to different crops based on their total returns, not on the irrigation water requirements. The study results suggest that the limiting/constraining groundwater extractions would induce farmers to reconsider their irrigation water demand. The study findings suggest an introduction of Rs. 0.04/m3 of groundwater would not decrease farm income rather it would make farmers aware of the economic value of water. We suggest that although water pricing can induce an efficient use of groundwater extractions, additional policies are also required that improve irrigation water use efficiency.
Timing outweighs magnitude of rainfall in shaping population dynamics of a small mammal species in steppe grassland
Publisher: Proceedings of the National Academy of Sciences
Date: 14-10-2021
Abstract: Disentangling the effects of rainfall timing and magnitude on animal and plant populations is essential to reveal the biological consequence of erse climate change scenarios around the world. We conducted a 10-y, large-scale, manipulative experiment to examine the bottom-up effects of changes in rainfall regime on the population dynamics of Brandt’s voles in the steppe grassland of Inner Mongolia, China. We found that a moderate rainfall increase during the early growing season could produce marked increases in vole population size by increasing the biomass of preferred plant species, whereas large increases in rainfall produced no additional increase in vole population growth. Our study highlights the importance of rainfall magnitude and timing on the nonlinear population dynamics of herbivores.
Can online search data improve the forecast accuracy of pork price in China?
Publisher: Wiley
Date: 28-01-2020
DOI: 10.1002/FOR.2649
Abstract: Online search data provide us with a new perspective for quantifying public concern about animal diseases, which can be regarded as a major external shock to price fluctuations. We propose a modeling framework for pork price forecasting that incorporates online search data with support vector regression model. This novel framework involves three main steps: that is, formulation of the animal diseases composite indexes (ADCIs) based on online search data forecast with the original ADCIs and forecast improvement with the decomposed ADCIs. Considering that there are some noises within the online search data, four decomposition techniques are introduced: that is, wavelet decomposition, empirical mode decomposition, ensemble empirical mode decomposition, and singular spectrum analysis. The experimental study confirms the superiority of the proposed framework, which improves both the level and directional prediction accuracy. With the SSA method, the noise within the online search data can be removed and the performance of the optimal model is further enhanced. Owing to the long‐term effect of diseases outbreak on price volatility, these improvements are more prominent in the mid‐ and long‐term forecast horizons.

Implications of Adoption of Zero Tillage (ZT) on Productive Efficiency and Production Risk of Wheat Production
Publisher: MDPI AG
Date: 05-2020
DOI: 10.3390/SU12093640
Abstract: The impacts of zero tillage (ZT) on soil physical, biological, and chemical properties have been fairly documented in the literature. However, there is still an information gap in the developing world in general and in integrated crop–livestock production systems in dry areas of the world in particular. Using a s le of 621 farmers in Syria, this study assessed the implications of adoption of ZT technology on productive efficiency, input-specific resource use efficiency, and production risk. A stochastic production frontier model, which explicitly and simultaneously accounts for technical inefficiency and production risk, was used to estimate total factor and input-specific technical efficiencies and the risk of obtaining lower levels of yields for each of the s led farms. Model results show that adoption of ZT proved to be an effective risk management strategy in this dryland production system, where it led to 95% and 33.3% reductions in the risk of obtaining wheat yield levels below 1000 kg/ha and 1500 kg/ha, respectively. Overall, the results have a clear indication that using ZT leads to improvements in productive efficiency as the adoption of ZT led to 93% reduction in the risk of obtaining efficiency levels below 40%. Future research will be needed to shed light on whether coupling ZT with the other components of conservation agriculture will reverse some of these effects.
Efficiency of irrigation water application in sugarcane cultivation in Pakistan
Publisher: Wiley
Date: 25-09-2015
DOI: 10.1002/JSFA.6887
Abstract: Diminishing irrigation water supplies are threatening the sustainability of irrigated agriculture in Pakistan. Within the context of dwindling water resources and low agricultural water productivity, it is imperative to improve efficiency in agricultural production and to make efficient use of available water resources. This study employs a non-parametric approach to estimate the extent of technical and irrigation water efficiency in sugarcane cultivation in Pakistan. The mean technical efficiency score is 0.96 for tube-well owners whereas it is 0.94 for water buyers. The mean irrigation water efficiency score is 0.86 for tube-well owners whereas it is 0.72 for water buyers. We find that across all farms, 59% of the tube-well owners and 45% of the water buyers are fully technically efficient, whereas only 36% of the tube-well owners and 30% of the water buyer are fully efficient in irrigation water use. This study finds that sugarcane growers are operating at fairly high technical efficiency levels. But, there is considerable potential to improve irrigation water efficiency. This study proposes expanding the role of agricultural extension services from merely agronomic grounds to guide farmers to undertake cost benefit analysis of the available production technology, would help achieve higher efficiency levels.

The choice of efficiency benchmarking metric in evaluating firm productivity and viability
Publisher: Springer Science and Business Media LLC
Date: 09-02-2022
DOI: 10.1007/S11123-022-00628-1
Abstract: The Debreu–Farrell measure of technical efficiency is widely used to benchmark firm performance. A limitation of this measure is that it is orientation restricted and evaluates the performance of a decision-making unit in an explicit direction relative to the best-practice frontier and not the most productive point on the frontier. Therefore, the measure does not provide policy insight on how to direct decision-making units to achieve the best possible productivity level. Taking a departure from conventional nonparametric benchmarking studies, this study benchmarks the performance of commercial farm businesses in the Western Australia’s wheatbelt region using total factor productivity efficiency (‘TFP efficiency’) and compares the results to those when the conventional technical efficiency measures are applied. We find that the two measures of firm performance differ and are influenced by different sources of firm heterogeneity. Therefore, derived policy insights and prescriptions also differ. This is an important insight that policymakers and practitioners need to be aware of.

DOI: 10.1108/00214660680001188
Abstract: This study investigates factors related to loan approval, disbursement, repayment, and loan rationing among 1,012 farmers in the Rural Farmers Scheme (RFS), Uganda, between 1987 and May 1995. Results indicate that women had a higher loan approval rate and loan repaid/loan borrowed ratio than men, but lower actual disbursement levels. Loan rationing among women and men was not statistically different, and no justification was found for microfinance institutions discriminating against women in giving loans based on repayment rates. A wide gap exists between loan amounts approved and disbursed. Strategies are outlined for improving the pool of women loan applicants.

Impact of multiple soil conservation practices on rice yields and chemical fertiliser use in China
Publisher: Emerald
Date: 27-07-2021
DOI: 10.1108/CAER-06-2020-0116
Abstract: This paper analysed survey data of 715 rice-producing households in China to assess the determinants of adoption of five mutually exclusive soil conservation practices (SCPs) and their impact on rice yield and chemical fertiliser use. The multinomial endogenous treatment effects model was used to account for selection bias and endogeneity arising from both observed and unobserved heterogeneity. Farms that adopted SCPs as a package experienced an increase in rice yield and decrease in chemical fertiliser use. Adoption of SCPs as a package led to a 12.0% increase in yield and 15.2% decrease in chemical fertiliser use these results have policy implications for the non-point source pollution control in the agricultural sector. In contrast, adoption of straw retention only significantly reduced yield by 4.9% and increased chemical fertiliser use by 18.1%. The authors evaluate and compare multi-type of SCPs, such as straw retention, deep tillage and use of organic fertiliser, separately or in combination, and their impacts on smallholder farmers’ rice yield and chemical fertiliser usage.
