Was the increase in income inequality in the US due to permanent shocks or merely to anincrease in the variance of transitory shocks? The implications for consumption and welfaredepend crucially on the answer to this question. We use CEX repeated cross-section data onconsumption and income to...

This paper analyzes the impact of limited enforceable international loanson international risk sharing and trade fluctuations in a two-country two-good endowment economy. Our specification of the punishment threat allowsthe exclusion from trade to last only finitely many periods and...

We develop a method that allows one to compute incomplete-market equilibria routinely forMarkovian equilibria (when they exist). The main difficulty to be overcome arises from the setof state variables. There are, of course, exogenous state variables driving the economy but, in anincomplete...

This paper develops a method to compute the equilibrium correspondence for exchangeeconomies with semi-algebraic preferences. Given a class of semi-algebraic exchange economiesparameterized by individual endowments and possibly other exogenous variables such as prefer-ence parameters or asset...

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

The paper examines a game-theoretic model of a …nancial market inwhich asset prices are determined endogenously in terms of short-runequilibrium. Investors use general, adaptive strategies depending onthe exogenous states of the world and the observed history of thegame. The main goal is to...

This article shows that, as long as agents are required to maintain positivewealth, the presence of portfolio constraints may give rise to asset pricingbubbles in equilibrium even if there are unconstrained agents in the economywho can benefit from the induced arbitrage opportunity. Furthermore,...

In this paper, we examine an exchange economy with a financial market composed of three assets: a share of a stock, an European call option written on the stock, and a riskless bond.

This paper considers the option pricing when dynamic portfolios are discretely rebalanced.

In this paper the authors measure the risk attitudes of bond investors which can be revealed from settled market prices. They present an equilibrium model which focuses on the stochastic behavior of tastes in addition to the dynamics of investor beliefs.
