It has become common to measure the quality of exports using their unit export value (UEV). Applications of this method include studies of intra-industry trade (IIT) and analyses of industrial "competitiveness". This literature seems to assume that export quality and export price (the most...

Helpman, Melitz and Rubinstein (2008) derive gravity equations to estimate effects of trade barriers on the intensive and extensive margins of trade. They exploit the frequency of zeros in aggregate bilateral trade data to identify effects on the extensive margin and to obtain controls for firm...

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...

Gravity equations have been used for more than 50 years to estimate ex post the partial effects of trade costs on international trade flows, and the well-known - and traditionally presumed exogenous - "trade-cost elasticity" plays a central role in computing general equilibrium trade-flow and...

This paper uses micro-data from the World Bank Investment Climate Surveys 2002-2006 to investigate how foreign ownership and access to external finance affect the likelihood of manufacturers in emerging markets to export and/or import. Applying propensity score matching to control for...

Twenty years of negotiations over reform of the United Nations Security Council (UNSC) are yet to bear fruit. We use recent advances in the theory of a-priori voting power to present a formal quantitative appraisal of the "structural reforms" contained within eleven current reform proposals, and...

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...

The accelerated overseas expansion of multinational retailers (MRs) over the last decade transformed these companies into major regional and global actors. In this paper we question how MRs arriving in foreign markets affect the export performance of local firms. We develop a theoretical...

We study how financial frictions affect firm-level heterogeneity and trade. We build a model where productivity differences across monopolistically competitive firms are endogenous and depend on investment decisions at the entry stage. By increasing entry costs, financial frictions lower the...
