In this paper we estimate gravity models to see whether trade volumes of countries in the MENA region are significantly lower than what would be expected given their economic, cultural and geographical characteristics. Our empirical results show that the variables used in standard gravity models...

This paper examines the impact of exchange rate regimes on bilateral trade while differentiating the effects of "words" and "deeds". Our findings-based on an extended database for de jure and de facto exchange rate classifications-show that while fixed exchange rate regimes increase trade, there...

This paper considers the effects of trade policy-tariffs and quotas-when importing is done by competitive traders who are identical ex ante but differ ex post. We show that the standard equivalence results no longer hold and the conventional ranking of tariffs and quotas is turned on its head:...

This paper examines the effect of unionization on welfare and trade policy in a model of duopolists competing in a third market. It shows that the traditional result that the presence of a union necessitates a stronger strategic trade policy to reach the optimal level of welfare depends on the...

This paper examines the composition of primary commodity exports by industrial countries and contrasts this composition with that of the exports by developing countries. Both the share of industrial countries’ commodity exports in world commodity exports, as well as in their own total...

This paper investigates whether a regional bloc would enlarge or remain stagnant in size using a model where enlargement is the endogenous outcome of the interaction between the supply of and demand for membership. We show that a maximum size of the bloc exists beyond which the regional...

This paper examines the empirical relationship between trade and total factor productivity (TFP) in South Africa. It uses (i) a time series approach where trade is defined in terms of aggregate outcomes, i.e., as the share of imports plus exports in GDP, and (ii) a cross sectional approach,...

Although a centerpiece of the reform process in Central and Eastern Europe, large-scale privatization cannot be undertaken all at once and policymakers inevitably face the choice of privatizing some sectors before others. This paper analyzes the allocative efficiency implications of alternate...

We study versions of a general equilibrium banking model with moral hazard under either constant or increasing returns to scale of the intermediation technology used by banks to screen and/or monitor borrowers. If the intermediation technology exhibits increasing returns to scale, or it is...
