The decomposition of national CAPM market betas of European countries’ value and growth portfolio returns into cashflow and discount rate news driven components reveals that i) high average returns on value portfolios are associated with disproportionately high sensitivity to national cashflow...

The paper analyzes the process of market selection of investment strategies in an incomplete asset market. The payoffs of the as-sets depend on random factors described in terms of a discrete-time Markov process. Market participants make dynamic investment de-cisions based on their observations...

Many postulated relations in finance imply that expected asset returns strictly increase in an underlying characteristic. To examine the validity of such a claim, one needs to take the entire range of the characteristic into account, as is done in the recent proposal of Patton and Timmermann...

This paper presents an application of evolutionary portfolio theory to stocks listed in the Swiss Market Index (SMI). We study numerically the long-run outcome of the competition of rebalancing rules for market shares in a stock market with actual dividends taken from firms listed in the SMI....

The purpose of this paper is to explain why some markets for financial products take off while others vanish as soon as they have emerged. To this end, we model an infinite sequence of CAPM--economies in which financial products can be used for insurance purposes. Agents' participation in these...

In the standard CAPM with a riskless asset we give a sufficient condition for uniqueness. This condition is a joint restriction on the agents' endowments and their preferences which is compatible with non-increasing absolute risk aversion and which is in particular satisfied with constant...

Incomplete consumption risk sharing implies that the market risk premium is high in times of lack of risk sharing and vice versa. In the time period from 1980 to 2007, this implication of incomplete consumption risk sharing for the market price of risk is not mirrored in excess returns on stocks...

We suggest a simple asset market model in which we analyze competitive and strategic behavior simultaneously. If for competitive behavior two-fund separation holds across periods then it also holds for strategic behavior. In this case the relative prices of the assets do not depend on whether...
