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 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...

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...

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...

Population movements will help people facing the impact of climate change. However, the resulting large scale displacements may also produce security risks for receiving areas. The objective of this paper is to empirically estimate if the inflows of climate-induced migrants increase the risk of...

Climate change, especially the warming trend experienced by several countries, could affect agricultural productivity. As a consequence, rural incomes will change, and with them the incentives for people to remain in rural areas. Using data from 116 countries between 1960 and 2000, we analyze...

We examine the effect of climate change on fertility rates and human capital accumulation in developing countries, focusing on the instrumental role of migration. In particular, we investigate how climate-induced migration in developing countries will affect those who do not migrate. Holding all...
