A three-dimension analytical framework for decision under risk is presented, in which preference is defined as a triadic reference-dependent relation as in Sugden (2003). Characterized by a set of von Neumann-Morgenstern-style axioms except that the independence axiom is assumed only for the...

This paper applies the dichotomous theory of choice by Zou (2000a) to the analysis of investment strategies and security markets. Issues concerning individual optimality, (approximate) arbitrage, capital market equilibrium, and Pareto efficiency are studied under various market conditions. <BR>...

We show in general that risky investments become more attractive as the investment horizon (n) lengthens. Specifically, any investor's maximal expected utility directly increases with n, as well as the investor's willingness to allocate more capital to the risky assets if his optimal strategy is...

We investigate necessary and sufficient conditions for threat-based incentive mechanisms (TBIMs), an extension of the Mirrlees's schemes, to approximately eliminate moral hazard in a principal-agent relationship with both problems of moral hazard and adverse selection. Assuming normal...

The issue of 'best-beta'; arises as soon as potential errors in the Sharpe-Lintner-Black capital asset pricing model (CAPM) are acknowledged. By incorporating a target variable into the investor preferences, this study derives a best-beta CAPM (BCAPM) that maintains the CAPM's theoretical appeal...
