Migration from Africa and the Middle East to the EU has intensified over the last two decades. Relative differences between developed EU and less developed African and Middle East countries have not declined that much and continue to drive mobility. Also, demographic trends show a strong...

The South-North migration corridor, i.e. migration flows to the EU from Africa, the Middle East and EU neighbouring countries in the East, have overtaken the East-West migration corridor, i.e. migration flows from Central and East European countries to the EU15 and the European Free Trade...

We use transaction-level US import data to compare firms from virtually all countries in the world competing in a single destination market. Guided by a simple theoretical framework, we decompose countries' market shares into the contribution of the number of firm-products, their average...

We derive a theory-based gravity-type equation that determines the main drivers of international technology diffusion under perfect enforcement of intellectual property rights. We estimate the gravity equation using bilateral royalty payments data for a sample of 53 countries and the period...

In recent years, young brain drain within Italian provinces has increased at higher speed than ever. While is premature to assess whether this process is transitory or permanent, it should be analysed and monitored by researchers and policy makers for its many socio-economic consequences....

This paper investigates the relationship between intra-industry trade (IIT) and immigration flows using a gravity model for the period 2000-2010 between Portugal and European Union’s Member States (EU-27). The present study uses the methodology of Kandogan (2003) for separating IIT into its...

This paper studies the effect of capital controls on misallocation and welfare in an economy with financial constraints. We build a general equilibrium model with heterogeneous firms, financial constraints and international trade and calibrate it to the Chilean economy. Since high-productivity...

We use transaction-level data to study changes in the concentration of US imports. Concentration has fallen in the typical industry, while it is stable by industry and country of origin. The fall in concentration is driven by the extensive margin: the number of exporting firm has grown, and the...

Trade flows are the result of the interaction between buyers and sellers. Understanding how these firm-to-firm relationships form, survive, and evolve over time helps identify how countries can improve their export outcomes. Using a very granular dataset of United States import transactions from...

We develop a quantitative theory of prices in firm-to-firm trade with bilateral negotiations and two-sided market power. Markups reflect oligopoly and oligopsony forces, with relative bargaining power as weight. Cost pass-through elasticities into import prices can be incomplete or complete,...
