Firm-level regressions show that Champagne producers that receive better ratings from wine guides also export to more markets, charge higher prices, and sell more in each market. Our method corrects for a severe selection bias predicted by the model. By using direct measures of quality, we can...

Despite the importance of industrial and geographical diversification of exports, the literature says little about what a “normal” level of diversification is. This paper takes a step in this direction and develops a methodology to measure a normal level of diversification along industry and...

This paper develops a methodology for trade policy analysis of costs and benefits of alternative regional integration scenarios, based on the disaggregated gravity equation, and applies it to calculate the impact of the EU enlargement on integration strategies of non-member countries. In...

We examine the qualitative and quantitative predictions of a heterogeneous firm model à la Melitz (2003) in the context of the Canada - US Free Trade Agreement (CUSFTA) of 1989. We calibrate our model to the pre-trade liberalization stage, simulate the trade liberalization, and compute the...

The present paper studies the variety gains of regional integration in Asia. Applying a heterogenous firm model we are able to assess the gains arising from the increased product and consumer choice, which is not possible in trade models with representative firms. We analyse the impacts of the...

Even if the debate on globalization pits sceptics and enthusiasts against one another, they seem to agree at least on exposing the protectionism of developed countries. This is illustrated by a recent report by OXFAM on trade, the way some enthusiasts have reacted to it, and miscellaneous...

We develop a multi-country Dixit-Stiglitz model to investigate the impacts of: (i) changes in the international distribution of consumers' expenditure; (ii) decreasing tariffs; and (iii) improvements in transportation infrastructure. We show that, in general, decreasing tariff barriers do not...

Using a numerical general equilibrium model we examine the possible production, trade and welfare effects of successful implementation of the Uruguay Round results. The model includes trade in manufactures and (some) services among industrial regions and countries; there is imperfect competition...

This paper reviews estimates of the effects of `1992' on international trade and welfare, and the policy implications of those estimates. It surveys earlier research starting with the Cecchini Report of 1988 and then summarizes some new results based on general equilibrium modelling with...

Standard theoretical models would predict that a currency depreciation generates an increase in net exports. However, recent emerging market crises, accompanied by sharp exchange rate devaluations, have often been followed by a fall in or a stagnation of exports. This paper provides a simple...
