We develop a dynamic model of a small open economy that trades commodities whose world prices are subject to realistic random fluctuations, and study the implications of monetary policy alternatives. The model is much more flexible than those of previous studies, especially in allowing to...

This paper develops recursive methods that completely characterize all the time-consistent equilibria of a class of models with long-lived agents. This class is large enough to encompass many problems of interest, such as capital- labor taxation and optimal monetary policy. The recursive methods...

The authors study how the effect of trade openness on economic growth depends on complementary reforms that help a country take advantage of international competition. This issue is illustrated with a simple Harris-Todaro model where output gains after trade liberalization depend on the degree...

This paper studies the cycles of nationalization and privatization in resource-rich economies. We discuss available evidence on the drivers and consequences of privatization and nationalization, review the existing literature, and present illustrative case studies. Our main contribution is then...

In recent years several countries have granted greater independence to their central banks; others have made price stability the only objective of monetary policy. These two trends can be seen as social responses to a fundamental problem of central bank credibility called the time inconsistency...

I study a small open economy in which elections affect and are affected by capital inflows. Two candidates, one favoring workers and another favoring entrepreneurs, run for office; the winner chooses taxes, which affect investment returns. A pro labor victory results in a "sudden stop" in...
