We provide necessary and sufficient conditions on an individual's expected utility function under which any zero-mean idiosyncratic risk increases cautiousness (the derivative of the reciprocal of the absolute risk aversion), which is the key determinant for this individual's demand for options...

In an exchange economy in which there is a complete set of markets for macroeconomic risks but no market for idiosyncratic risks, we consider how the efficient risk-sharing rules for the macroeconomic risk are affected by the heterogeneity in the consumers' risk attitudes and idiosyncratic...

We develop a continuous time general equilibrium yield curve model under ambiguity aversion. Even a moderate level of 'aggregate ambiguity' affects significantly the term structure and can drive the prices of common interest rate derivatives toward the patterns observed in fixed income markets....

We provide a necessary and a sufficient condition on an individual's expected utility function under which any zero-mean idiosyncratic risk increases cautiousness (the derivative of the reciprocal of the absolute risk aversion), which is the key determinant for this individual's demand for...

A new alternative diffusion model for asset price movements is presented. In contrast to the popular approach of Brownian motion it proposes deterministic diffusion for the modelling of stock price movements. These diffusion processes are a new area of physical research and can be created by the...

This paper examines the effect of competition on the irreversible investment decisions under uncertainty as a generalization of the quot;real optionquot; approach. We examine this issue with reference to an industry where each firm has only one investment opportunity which is completely...

The thesis presents a construction of a grid that discretizes the threshold model introduced by Geman and Roncoroni (2006) for electricity spot prices, incorporating both mean reversion and jumps, the direction of the latter depending on the price of the underlying at the time of the jump. The...

Under the framework of Rational Expectation Equilibrium (REE), the paper analyzes the impacts of insider trading on the secondary market in the order-driven system. We show that when insider trading is allowed, the average price will not change and there is a positive correlation between the...

Combining Leland (1992), Madhavan (1992) and Repullo (1999) and under the framework of Rational Expectation Equilibrium (REE), the paper analyzes the impact of insider trading on the secondary market with order-driven system. We show that when insider trading is allowed, the average price will...

This study extends Seck's (1996) approach to investigate the degree of substitutability between equity real estate investment trusts (EREITs) and mortgage real estate investment trusts (MREITs). The variance ratio test and the variance decomposition of forecast errors yield results indicating...
