On the eve of a major change in the world monetary system, the adoption of a single currency in Europe, our theoretical understanding of the implications of the exchange rate regime for trade and capital flows is still limited. We argue that two key model ingredients are essential to address...

In this paper, we first introduce investment-specific technology (IST) shocks to an otherwise standard international real business cycle model and show that a thoughtful calibration of them along the lines of Raffo (2009) successfully addresses the quantity, international comovement,...

Credit constraints that link a private agent’s debt to market-determined prices embody a credit externality that drives a wedge between competitive and constrained socially optimal equilibria, inducing private agents to overborrow. The externality arises because agents fail to internalize the...

A puzzle in international macroeconomics is that observed real exchange rates are highly volatile. Standard international real business cycle (IRBC) models cannot reproduce this fact. We show that total factor productivity processes for the United States and the rest of the world are...

In recent years, Bolivia has accumulated a significant level of international reserves due to favorable external environment and the exchange rate regimen (crawling peg). In this context arises the question of: Which one is the optimal level of international reserves? According to the...

The withdrawal of foreign capital from emerging countries at the height of the recent financial crisis and its quick return sparked a debate about the impact of capital flow surges on asset markets. This paper addresses the response of property prices to an inflow of foreign capital. For that...

We analyse the effect of the uncertainty about the fundamentals on the probability of sudden stops of capital flows from a theoretical and empirical perspective. Our model predicts that the probability of crises increases with the uncertainty, ie. the dispersion of private signals about the true...

This paper analyzes the impact of uncertainty on the spread of stock market crises, both theoretically and empirically. The effect of uncertainty about the fundamentals on investment decisions is an important cause of financial crises propagating across countries. Firstly, a coordination game on...

We study the labor market effects of bilateral exchange rate realignment. We place emphasis on the composition of trade, the role of intermediates, and the underlying conditions of the labor market. Employment effects hinge on the fraction exported to and imported from the trading partner. A...

The present value model of the current account has been very popular, as it provides an optimal benchmark to which actual current account series have often been compared. We show why persistence in observed current account data makes the estimated optimal series very sensitive to small-sample...
