Markups vary widely across industries and countries, their heterogeneity has increased overtime and asymmetric exposure to international trade seems partly responsible for this phenomenon. In this paper, we study how the entire distribution of markups affects re- source misallocation and welfare...

New Economic Geography (NEG) models are difficult to confront with the data, since "on the one hand, they generally emphasise the unleashing of agglomeration forces after trade liberalisation, but on the other hand, they also accomodate multiple equilibria and non-monotonicity" (Brülhart,...

In this paper we analyse the dynamics of trade patterns in the six largest industrialised countries and in eight fast growing Asian economies. For each of these countries we study the shape of the sectoral distribution of an index of trade specialisation and its evolution over time. Our analysis...

We argue that, in the presence of asymmetric countries, a trade agreement that conforms to GATT’s reciprocity rule allows the (stronger) less trade dependent country to improve its welfare relative to both the free trade and the trade war. Conversely, the (weaker) more trade dependent country...

We argue that, with an elasticity of substitution in consumption greater than one and higher scale economies in the skill-intensive sectors, the entire volume of world trade matters for wage inequality. This implies that trade integration, even among identical countries, is likely to increase...

We review the micro-level evidence on the effects of trade and investment liberalization in the developing world. The main findings can be summarized as follows. 1) There is evidence of trade-induced productivity gains; 2) These gains mainly stem from the intra-industry real-location of...

We study the effects of trade integration on the regional coevolution of income, migrations and unemployment in a dynamic core-periphery model with limited labor mobility and frictions in the job matching process. Our model can help explain a recently documented empirical puzzle, i.e., the...
