Skilled Migration and Economic Performances: evidence from OECD countries

This paper investigates the effects of immigration flows and their skill content on per capita GDP in 24 OECD host countries. Theoretical models concludes that the effect of immigrants in host country's income depends on the capital content of migrants (Benhabib 1996); empirically the question is still open and this paper contributes to make light on this. So we propose an empirical estimation on the effects of immigrants and their skill level on per capita GDP. Using a IV model to solve the endogeneity problem we found that high skilled migration has a positive effect on per capita GDP, but it is not enough to fully compensate the overall negative effects of migration on per capita GDP.International migration, economic performances, factor mobility

Design and experimental validation of Convex Conformal Reflectarray Antennas

In this work the design, the numerical analysis and the experimental characterization of a Convex conformal Reflectarray (CRA) has been carried out, with the aim of investigating the feasibility of reflectarrays bent on convex curved surfaces. A medium-size offset CRA in Ka-band has been designed, and a demonstrator has been manufactured and measured. The results prove the correctness of the design procedure and the feasibility of this type of antenna, pointing out the differences, also in terms of radiation performances, with respect to a planar reflectarra

The International Elasticity Puzzle Is Worse Than You Think

We instrument export prices with firm level electricity cost shocks and estimate three international price elasticities using firm-level export data: the elasticity of firm exports to export price, tariff and real exchange rate shocks. In standard models these three elasticities should be equal. We find that this is far from being the case. The export price elasticity is the highest, around 5, much larger than the exchange rate elasticity. The international elasticity puzzle is therefore worse than previously thought. We also show that exporters absorb one third of tariff changes in their export prices. Because we take into account this reaction of export prices to tariffs, our estimate of the tariff elasticity corrects from this omitted-variable bias

Skilled Migration and Economic Performances: Evidence from OECD Countries

This paper investigates the effects of immigration flows and their human capital content on per capita GDP variation in 24 OECD host countries. Theoretical models concludes that the effect of immigrants in host country's income depends on the human capital content of migrants (Benhabib, 1996); empirically the question is still open and this paper contributes to make light on this. So we propose an empirical estimation on the effects of immigrants and their human capital content on per capita GDP variation. Using a IV model to solve the endogeneity problem we found that high human capital content by immigrants has a positive effect on per capita GDP variation, but it is not enough to fully compensate the overall negative effects of migration on changes in per capita output.international migration; economic performances; factor mobility

Let’s try next door: Technical Barriers to Trade and multi-destination firms

International audienceStringent Technical Barriers to Trade (TBT) are expected to drive exporters out of the markets imposing these hurdles. In addition, more able multi-destination exporters can refocus on TBT-free markets and reorient their exports. By matching a database of TBT measures raised as concerns at the WTO (Specific Trade Concerns -- STCs), with a firm-level panel of French exporters, we show the complex effects of restrictive TBT measures on the different margins of trade. We show that the negative effect of TBT on export participation is magnified for multi-destination firms, which can divert their exports towards TBT-free destinations. Moreover, we conduct aggregate level estimations to show that the effect of stringent TBTs in reducing export flows is magnified in more homogeneous sectors. Observing the shape of the firm distribution at sectoral level and the aggregate response of export to trade cost, we shed light on the fixed component of the additional cost imposed by TBTs on exporters
