This Paper analyses the exchange rate in a ‘no-arbitrage’ or ‘real business cycle’ equilibrium model and provides empirical evidence for this model vis-a-vis PPP. Our contribution is to show, based on a generalization of the equilibrium model of exchange rates, that (i) the test equation...

We study the effect of introducing a new security, such as a non-redundant derivative, on the volatility of stock-market returns. Our analysis uses a standard, continuous time, dynamic, general-equilibrium, full-information, frictionless, Lucas endowment economy where there are two classes of...

In this paper, we study asset prices in a dynamic, continuous-time, general-equilibrium endowment economy where agents have “catching up with the Joneses” utility functions and differ with respect to their beliefs (because of differences in priors) and their preference parameters for time...

East European countries have experienced sharp declines in real GDP since 1990. One of the reasons for this decline is the Soviet trade shock caused by the collapse of the CMEA and of traditional export markets in the Soviet Union. This paper is an attempt to quantify the magnitude of this...

By the end of 1991, Czechoslovakia, Hungary and Poland had achieved a substantial degree of openness to foreign trade. In all three countries, trade is now demonopolized and licensing and quotas play a very small role. Exchange controls have virtually disappeared for current-account...

This paper studies the relationship between political conflict and economic growth in a simple model of endogenous growth with distributive conflicts. We study both the case of two `classes' (workers and capitalists) and the case of a continuum distribution of agents, characterized by their...

The nation-state system, democratic politics, and full economic integration are mutually incompatible. Of the three, at most two can be had together. The Bretton Woods/GATT regime was successful because its architects subjugated international economic integration to the needs and demands of...

The design of institutions is shaped by a fundamental trade-off. On the one hand, relationships and heterogeneity push governance down. On the other, the scale and scope benefits of market integration push governance up. A corner solution is rarely optimal. An intermediate outcome, a world...
