This paper argues that the theoretical foundations for the gravity equation are general, while the empirical performance of the gravity equation is specific to the type of goods examined. Most existing theory for the gravity equation depends on the assumption of differentiated goods. We show...

This paper analyzes aspects of the economics of the optimal management of exchange rates. It shows that the choice of the optimal exchange rate regime depends on the nature and the origin of the stochastic shocks that affect the economy. Generally, the higher is the variance of real shocks which...

The purpose of this paper is to determine whether a two-tier exchange rate regime is more effective than a fixed rate regime in increasing acountry's ability to pursue an independent monetary policy in the short run.The analysis compares adjustment to a monetary policy and to a devaluation in...

We show that increased uncertainty about the size of an emerging market's external debt has a nonlinear and potentially large adverse effect on the supply of international credit offered to them. We also show that if international creditors are first- order risk averse, attaching greater weight...

This paper investigates the impact of the history of crises on macroeconomic performance. We first study the impact of past banking crises on the probability of a future banking crisis. Applying data for 1980‐2010 for all countries for which the required information is available, controlling...

We formulate a two-country model with monopolistic competition and heterogeneous firms to reconsider labor market linkages in open economies. Labor-market imperfections arise by virtue of country-specific real minimum wages. Two principal experiments are considered. First, we show that trade...

Recent literature has highlighted the importance of new activities in development and growth. It was shown that trade distortions such as tariffs are associated with first-order costs stemming from the induced drop in the formation of new activities. This paper demonstrates that uncertainty may...

This paper evaluates the welfare implications of privatization in emerging market economies, in countries where policies are determined by the median voter. We show that privatization may lead to large efficiency gains by changing the menu of taxes. We illustrate this point with two examples....

This paper sets up a general oligopolistic equilibrium model with unionized labor markets. By accounting for productivity differences, the model features profit and wage differentials across industries. We use this setting to study the impact of trade liberalization on employment, welfare, and...
