We develop a model of international trade with two dimensions of firm heterogeneity. The first dimension is “process productivity”, which is how we denote the standard concept of productivity as modeled in the literature. The second one is “product productivity”, defined as firms'...

The aim of this paper is to analyze the trade specialization in the leather products between some selected Asian economies, with particular focus on Pakistan. For which, a measure of Revealed Comparative Advantage (RCA Balassa Index) is used. The analysis shows that Pakistan has a high...

This paper investigates the effects of mergers on the product mix of multiproduct firms. Thus, we open the black box of post-merger efficiency improvements to reveal a new margin of adjustment along the product dimension. We analyze horizontal mergers in a theoretical model where oligopolistic...

This note explores the relationship between the price elasticity of demand and the R&D intensity of the product. We introduce the concept of R&D intensity into a standard Dixit-Stiglitz/Krugman-type setting. R&D activity is treated as a fixed cost of production. Within this framework, sectors...

It is almost common knowledge that foreign trade in Europe is characterized by an acceptance of prices set by the world market. Coupled with a constant profit share in domestic sectors this makes European exports vulnerable to vagaries of international demand and prices as well as to crowding...

This paper studies the impact of a regional free trade agreement, MERCOSUR, on technology upgrading by Argentinean firms. To guide empirical work, I introduce technology choice in Melitz’s (2003) model of trade with heterogeneous firms. The joint treatment of the technology adoption and...

Intervention to support export initiatives is commonplace in both industrialised and developing countries. Historically this has been underpinned by a belief that exporting is good for growth. But the evidence base underpinning this belief has been macroeconomic, yet intervention has generally...

I find evidence that the geographic expansion of firm exports occurs slowly over time and that a large share of export growth is due to incumbent exporters entering new destinations. New exporters enter large countries and destinations with characteristics similar to their domestic market. Less...

We develop a model to estimate simultaneously import shares, export shares, outward foreign direct investment and domestic profits for a large sample of U.S. manufacturing industries. In our model, trade barriers alter the ability of domestic market structure to influence domestic performance....
