We study a strategic model of dynamic trading where agents are asymmetrically informed over common value sources of uncertainty. There is a continuum of uninformed buyers and a finite number of sellers, some of them informed. When there is only one seller, full information revelation never...

We present a model of secured credit chains in which assets generated from intermediation activity and pledged as collateral create fragility. A dealer stands between a borrower and a financier. The dealer borrows from the financier to fund her project, subject to a moral hazard problem, In...

When individuals' labor and capital income are subject to uninsurable idiosyncratic risks, should capital and labor be taxed, and if so, how? In a two-period general equilibrium model with production, we derive a decomposition formula of the welfare effects of these taxes into insurance and...

We consider an economy where individuals face uninsurable risks to their human capital accumulation and study the problem of determining the optimal level of linear taxes on capital and labor income together with the optimal path of the debt level. We show both analytically and numerically that...

The paper examines a game-theoretic evolutionary model of anasset market with endogenous equilibrium asset prices. Assetspay dividends that are partially consumed and partially rein-vested. The investors use general, adaptive strategies (portfo-lio rules), distributing their wealth between...

The pricing kernel puzzle is the observation that the pricing kernelmight be increasing in some range of the market returns. This paperanalyzes the pricing kernel in a nancial market equilibrium. If mar-kets are complete and investors are risk-averse and have common andtrue beliefs, the pricing...

Experimental stock markets are used to add some more evidence that Blacks (1976) leverage effect in financial markets does not necessarily stem from the financial leverage of the firm. We surprisingly find a large number of markets in which the leverage effect is observed although the underlying...

We consider a simple CAPM with heterogenous expectations on assets mean returns while keeping the assumption of homogenous expectations on the covariance of returns. Our first result derives the security market line as an aggregation result without using the two-fund-separation property. In...

The prospect theory of Kahneman and Tversky (1979) and the cumulative prospect theory of Tversky and Kahneman (1992) are descriptive models for decision making that summarize several violations of the expected utility theory. This paper gives a survey of applications of prospect theory to the...

In this paper we suggest a behavioral foundation for the reward-risk approach to portfolio selection based on prospect theory. We identify sufficient conditions for mutual fund separation in reward-risk models in general and for prospect theory in particular. It is shown that a prospect theory...
