Two-price quantitative finance. This project aims to establish a novel field, namely two-price quantitative finance, and explore its applications. The new field will integrate two major schools for modelling and explain the presence of two prices, the buying and selling prices, widely observed in the real-world markets, and the equilibrium approach from the fundamental law of one price. The outcomes would deepen our understanding of the fundamental relationship among liquidity, prices, risk and ....Two-price quantitative finance. This project aims to establish a novel field, namely two-price quantitative finance, and explore its applications. The new field will integrate two major schools for modelling and explain the presence of two prices, the buying and selling prices, widely observed in the real-world markets, and the equilibrium approach from the fundamental law of one price. The outcomes would deepen our understanding of the fundamental relationship among liquidity, prices, risk and the economy. This project expects to bring about long-term impact on quantitative finance and related applications through providing a deep understanding of, and a new perspective for, the design, risk and fairness of the finance, property and insurance markets.Read moreRead less
The effect of bans on short selling: a comprehensive study. Although the 2008 financial crisis has greatly impeded the global economy, it has provided a rare opportunity for researchers to verify the truthfulness of some assumptions made on financial markets that are running without liquidity problems. This project will develop a new option pricing theory suitable for financial markets under some short-selling restrictions. Through exploring, from both empirical and theoretical points of view, h ....The effect of bans on short selling: a comprehensive study. Although the 2008 financial crisis has greatly impeded the global economy, it has provided a rare opportunity for researchers to verify the truthfulness of some assumptions made on financial markets that are running without liquidity problems. This project will develop a new option pricing theory suitable for financial markets under some short-selling restrictions. Through exploring, from both empirical and theoretical points of view, how short-selling bans will affect some important assumptions made in conventional option pricing theory, the newly developed option pricing framework should not only assist in trading options, but also assist market regulators to effectively use bans on short selling to stabilise financial markets.Read moreRead less
Liquidity in financial markets. This project aims to develop a theory which models the effect of liquidity on option prices under different market conditions. Economic or financial crises are inevitable and affect economics. During or after a major financial crisis, market liquidity usually becomes risky and needs to be studied. Through both empirical and theoretical explorations, this project will quantify and measure liquidity risk and its effect on the options markets. It will develop a frame ....Liquidity in financial markets. This project aims to develop a theory which models the effect of liquidity on option prices under different market conditions. Economic or financial crises are inevitable and affect economics. During or after a major financial crisis, market liquidity usually becomes risky and needs to be studied. Through both empirical and theoretical explorations, this project will quantify and measure liquidity risk and its effect on the options markets. It will develop a framework to help market regulators manage illiquidity, enhance the efficiency of option trading in illiquid markets and help in the detection of market manipulation.Read moreRead less
G-expectation and its applications to nonlinear risk management. This project will develop novel theories and methods for nonlinear risk management based on nonlinear expectations and Backward Stochastic Differential Equations. The expected outcomes of the project will place Australia in the forefront and the leading position of these fields.
