How does a country's choice of exchange rate regime impact its ability to borrow from abroad? We build a small open economy model in which the government can potentially respond to shocks via domestic monetary policy and by international borrowing. We assume that debt repayment must be incentive...

This paper studies consumption and labor supply in a model where agents have partial insurance and face risk and initial heterogeneity in wages and preferences. Equilibrium allocations and variances and covariances of wages, hours and consumption are solved for analytically. We prove that all...

Macroeconomics is evolving from the study of aggregate dynamics to the study of the dynamics of the entire equilibrium distribution of allocations across individual economic actors. This article reviews the quantitative macroeconomic literature that focuses on household heterogeneity, with a...

In this paper, we construct the first constant-quality aggregate price index for the stock of residential land in the United States. In the process, we uncover four main results: (a) since 1970, residential land prices have risen nearly twice as fast, but also have been twice as volatile as...

This paper builds a simple theoretical model designed to study dollarization. Each period, a benevolent government decides whether or not to dollarize, how much to borrow or lend on an international bond market, and, if dollarization has not occurred, the devaluation rate. In equilibrium,...
