In this paper, we analyze the consequences of increasing MENA-to-EU migration flows on both sending and receiving regions. In the first part of the paper, we characterize the structure of MENA emigration as well as the demographic trends in the EU and MENA. We show that EU27 is a major...

This paper reviews the existing literature on the impact of migrants networks on the patterns of international migration. It covers the theo- retical channels at stake in the global effect of the networks. It identifies the key issues, namely the impact on size, selection and concentration of...

In this paper, we attempt to understand the determinants of mobility through introducing the concept of local social capital. Investing in local ties is rational when workers do not expect to move to another region, and reciprocally, once local social capital is accumulated, incentives to move...

In this paper, we analyse competition among jurisdictions to attract firms through low taxes on capital and/or high level of public goods, which enhance firms' productivity. We assume that the competing jurisdictions are different in (population) size and that the mobility of capital is costly....

Armchair evidence shows that many industries are made of a few big commercial or manufacturing firms, which are able to affect the market outcome, and of a myriad of small family-run businesses with very few employees, each of which has a negligible impact on the market. Examples can be found in...

In this paper, we analyze the determinants of the production of research by higher edu- cation institutions in the U.S.. We use the information contained in the Shanghai ranking to estimate their performance in the production of top level academic research. We show that it is important to...

We use 29 OECD countries data spanning over 1960-2000 to study the growth strategy when countries are close to the technology frontier. Relying on a semi-parametric generalized additive model, we estimate labor productivity equations. We find that the number of agents enrolled in higher...

Migration flows are shaped by a complex combination of self-selection and out-selection mechanisms. In this paper, we analyze how existing diasporas (the stock of people born in a country and living in an another one) affect the size and human-capital structure of current migration flows. Our...

We analyze financial risk premiums and real economic dynamics in a DSGE model with three types of agents - shareholders, bondholders and workers - that differ in participation in the capital market and in attitude towards risk and intertemporal sub- stitution. Aggregate productivity and...
