This paper describes strategic behavior in a nonequilibrium model of asset pricing with heterogeneous sophistication. Both risk and return are increasing in the naïveté of investors in the market. Optimal investment involves considering the effect that naïve investors have on the market. Further, we derive a simple characterization of the asset price dynamics that results from an arbitrary comb...

As emphasized by Giovannini and Labadie (1991), empirical regularities involving nominal interest rates, asset prices, and inflation should be ultimately determined by money. The role of money, however, is almost neglected, particularly in terms of asset-pricing literature. This paper attempts to investigate the role of money in asset pricing in Japan. Specifically, it compares the empirical pe...

Asset pricing formulas generated from representative agent models help in computing the fundamental values of assets that investors plan to hold forever. In contrast, in an economy with heterogeneous agents and active trading, stock prices will persistently deviate from the expected fundamental value even without introducing any explosive bubbles. Particularly, the introduction of heterogeneous...

This paper explores the ability of theoretically-based asset pricing models such as the CAPM and the consumption CAPM referred to jointly as the (C)CAPM to explain the cross-section of average stock returns. Unlike many previous empirical tests of the (C)CAPM, we specify the pricing kernel as a conditional linear factor model, as would be expected if risk premia vary over time. Central to our a...

explanation relation between risk and return and capital asset pricing are concepts which is appointed as dominator and major paradigms in capital markets. so far as after offering capm by sharp & lintner, this model has been revised and criticized frequently. in this paper another version of capm has been tested versus traditional capm in tehran stock exchange. this version of capm measures se...

Concepts of constant absolute risk aversion and constant relative risk aversion have proved useful in the analysis of choice under uncertainty, but are quite restrictive, particularly when they are imposed jointly. A generalization of constant risk aversion, referred to as invariant risk aversion is developed. Invariant risk aversion is closely related to the possibility of representing prefere...

In this thesis, I provide new insights in the field of asset pricing and portfolio optimization by investigating the role of information and factor decompositions. In particular, I investigate the effect of disentangling specific risk factors as used in the earlier asset pricing and portfolio allocation literature into their different sub-components. In Chapter 2, I propose an extension to the ...

We study properties of structured financial products optimizing a utility functional of a customer. The conventional method may have the disadvantage that the a priori restriction to a certain number of assets could make it impossible to find the optimal portfolio. So instead of optimizing the distribution of given assets, we impose only the price constraint as given by the CAPM and optimize th...

This paper extends Merton’s continuous time (instantaneous) mean-variance analysis and the mutual fund separation theory. Given the existence of a Markovian state price density process, the optimal portfolios from concave utility maximization are instantaneously mean-variance efficient independent of the concave utility function’s form. The Capital Asset Pricing Model holds with the market port...
