The paper presents a general equilibrium model of a pure exchange economy with stochastic endowment in which speculation is profitable and stabilizes prices, but is useless from a welfare point of view. Reconciling the Siegel paradox with the theory of incomplete markets we show that banning...

This paper investigates the dynamic behavior of an economy with multiple Nash equilibria. The first part of the paper analyzes an abstract game exhibiting multiple equilibria. A history dependent selection criterion is proposed which induces correlated behavior in equilibrium even though agents...

In this paper we investigate the macro-economic equilibria of an economy in which credit contracts have both adverse selection and incentive effects. The terms of credit contracts include both an interest rate and a collateral requirement. We show that in this richer model all types of borrowers...

partial-adjustment-to-target behavior typically postulated in the monetary approach literature. The existence of a rational expectations equilibrium in which the distribution of international reserves among central banks is stationary is established

This paper encompasses multiple sources of inefficiency introduced by the U.S. tax system into a single general equilibrium model. Using disaggregate calculations of user cost, we measure interasset distortions from the differential taxation of many types of assets. Simultaneously, we model the...

This paper analyzes strategic monetary policies using a standard two country stochastic macro model. Three noncooperative equilibria, namely Cournot, Stackelberg, and Consistent Conjectural Variations, are considered.The Pareto Optimal equilibrium, where aggregate joint costs are minimizedis...

This paper examines an economy in which aggregate shocks are not dispersed equally throughout the population. Instead, while these shocks affect all individuals ex ante, they are concentrated among a few ex post.The equity premium in general depends on the concentration of these aggregate...

This paper analyzes exchange rate management in a simple overlapping generations model. This framework is used to evaluate alternative policies in terms of their implications for the welfare of individuals in the economy.The analysis identifies two objectives of monetary policy,providing...

The paper reviews theoretical developments in the field of exchange rate theory and assesses the empirical evidence. Since the empirical evidence does not lend support to the models that have been formulated, a number of reasons for that failure are suggested. These include the argument that the...
