Firm size follows Zipf's Law, a very fat-tailed distribution that implies a few large firms account for a disproportionate share of overall economic activity. This distribution of firm size is crucial for evaluating the welfare impact of economic policies such as barriers to entry or trade...

This paper makes a tentative forecast of the impact on Spanish trade of the liberalization of economic transactions between the EU and the former communist countries of Central and Eastern Europe (CEECs), as envisaged in the Association Agreements aimed at the eventual enlargement of the EU to...

Estimates for ad valorem tariff equivalents of services trade restrictions for cross-border trade in six services sectors are presented in this paper. These equivalents are found to be very big in several service sectors with estimates ranging as high as 2000% when trade flows are relatively...

Over the past two decades, governments worldwide have continued to liberalise restrictions on international investment with only occasional relapses. Yet, FDI liberalisation remains an unfinished agenda in various parts of the world and across sectors. This paper sheds light on their potential...

In this paper the authors develop an innovative 21 sector computable general equilibrium model of Armenia to assess the impact on Armenia of a Deep and Comprehensive Free Trade Agreement (DCFTA) with the EU, as well as further regional or multilateral trade policy commitments. They find that a...

Despite the fact that many modern preferential trade agreements include commitments to foreign investors in imperfectly competitive services sectors, the literature has not established conditions under which these agreements are beneficial or harmful. The authors fill that void by developing a...

There is widespread evidence that a better access to markets contributes to raising income levels. However, no quantification of the impact of distance to markets has been made on the basis of a sample restricted to advanced — and therefore more homogeneous — countries. This paper applies...

A country or firm's position in the value chain will largely depend on its comparative advantage, and therefore the mix of skills and resource endowments it brings to international production. For some, this might initially involve specialising in the labour intensive segments while others may...

We review a recent body of theoretical work that aims to put numbers on the consequences of globalization. A unifying theme of our survey is methodological. We rely on gravity models and demonstrate how they can be used for counterfactual analysis. We highlight how various economic...

A model of heterogeneous firms with variety-specific fixed costs is developed and analyzed to study how multiproduct firms respond to globalization. In contrast with most existing models, the analysis demonstrates that more-productive firms may expand their product scope, which in turn may push...
