We construct an intertemporal equilibrium with two agents with heterogeneous beliefs. Heterogeneity of beliefs induces volatility of the interest rate. We study the effect of financial innovation on interest rate volatility and conclude that, in a setting of asymmetric beliefs, introducing the...

This essay lists theoretical reasons why neoclassical models of one-sector growth imply that nations with identical economic structures need not converge to the same steady state or balanced growth path, and outlines the empirical significance and policy implications of conditional...

We build a partial equilibrium model of firm dynamics under exchange rate uncertainty. Firms face idiosyncratic productivity shocks and observe the current level of the real exchange rate each period. Given their current level of capital stock, firms make their export decisions and choose how...

It is argued that migration from Mexico to the US and return migration are determined by international wage differentials and preferences for origin. We use a model of job search, savings and migration to show that job turnover is a crucial determinant of the migration process. We estimate this...

In this paper we consider a sequential trading economy with incomplete financial markets and a finite number of infinitely lived agents. We propose a specification of agents' budget sets and show that such specification features several desirable properties. We then establish the existence of an...

I establish new existence and welfare results for the Kiyotaki-Wright model (JPE, 1989). I show that good intrinsic properties are not necessary for an object to be universally accepted in equilibrium. Furthermore, bad objects may be socially desirable as media of exchange. One result is that...

We take a game-theoretic approach to the analysis of juries by modelling voting as a game of incomplete information. Rather than the usual assumption of two possible signals (one indicating guilt, the other innocence), we allow jurors to perceive a full spectrum of signals. Given any voting rule...

How will the distribution of welfare, consumption and leisure across households be affected by social security reform? This paper addresses this question for social security reforms with a two-tier structure by comparing steady states under a realistic version of the current US system and under...

In a simple public good economy, we propose a natural bargaining procedure whose equilibria converge to Lindahl allocations as the cost of bargaining vanishes. The procedure splits the decision over the allocation in a decision about personalized prices and a decision about output levels for the...

Most monetary growth models have a relatively simple structure. There are two assets, money and capital, and money is held either because it earns the same real return as capital, or because it is ascribed an advantage in transacting that is not explicitly modelled. Financial market institutions...
