A striking pattern in transaction-level data is the concentration of international shipments in the hands of a few large firms. One common feature of dominating high-performance firms is that they produce multiple products and ship them to many destinations. Motivated by the emergence of highly...

This paper develops a new international trade model with capital market imperfections and endogenous borrowing costs in general equilibrium. Our theoretical model is motivated by new empirical patterns from enterprise survey data of the World Bank. Observing that a substantial fraction of the...

This paper develops a new international trade model with capital market imperfections and endogenous borrowing costs in general equilibrium. A key element of our model is that firm heterogeneity arises from the interaction of credit constraints at the firm-level with financial frictions at the...

This paper examines the role of the burden of proof (BoP) in National Treatment (NT) disputes under trade agreements. In the situation under study, imports may cause environmental damage, in which case less favorable treatment of imported products may be globally desirable from an international...

We examine the setting of national competition policy in a two-country setting,emphasizing the relationship of trade to the goals of competition policy (suchas the degree and nature of competition). The issues we address involve thegeneral equilibrium distributional effects of competition...

We investigate the effect of better access to foreign markets on innovation strategies of multi-product firms in industries with different scope for product differentiation. Industry-specific demand and cost linkages induce a distinction between the returns to innovation. In differentiated...

This paper studies the innovation strategies of multi-product firms in industries with different scope for product differentiation. In a simple model of multi-product firms, we show that returns to product versus process innovation are industry-specific. Demand and cost linkages induce a natural...
