Immigration and Occupations in Europe

In this paper we analyze the effect of immigrants on natives’ job specialization in Western Europe. We test whether the inflow of immigrants changes employment rates or the chosen occupation of natives with similar education and age. We find no evidence of the first and strong evidence of the second: immigrants take more manual-routine type of occupations and push natives towards more abstract complex jobs, for a given set of observable skills. We also find some evidence that this oc-cupation reallocation is larger in countries with more flexible labor laws. As abstract-complex tasks pay a premium over manual-routine ones, we can evaluate the positive effect of such reallocation on the wages of native workers. Accounting for the total change in Complex/Non Complex task supply from natives and immigrants we find that immigration does not change much the relative compen-sation of the two types of tasks but it promotes the specialization of natives into the first type.immigration, task specialization, European labor markets

The labor market impact of immigration in Western Germany in the 1990's

We adopt a general equilibrium approach in order to measure the effects of recent immigration on the Western German labor market, looking at both wage and employment effects. Using the Regional File of the IAB Employment Subsample for the period 1987-2001, we find that the substantial immigration of the 1990's had no adverse effects on native wages and employment levels. It had instead adverse employment and wage effects on previous waves of immigrants. This stems from the fact that, after controlling for education and experience levels, native and migrant workers appear to be imperfect substitutes whereas new and old immigrants exhibit perfect substitutability. Our analysis suggests that if the German labor market were as 'flexible' as the UK labor market, it would be more efficient in dealing with the effects of immigration. --Immigration,Skill Complementarities,Employment,Wages

Immigration, jobs and employment protection: Evidence from Europe before and during the great recession

In this paper we analyze the impact of immigrants on the type and quantity of native jobs. We use data on fifteen Western European countries during the 1996-2010 period. We find that immigrants, by taking manual-routine type of occupations pushed natives towards more complex (abstract and communication) jobs. Such positive reallocation occurred while the total number of jobs held by natives was unaffected. This job upgrade was associated in the short run to a 0.6% increase in native wages for a doubling of the immigrants' share. These results are robust to the use of two alternative IV strategies based on past settlement of immigrants across European countries measured alternatively with Census or Labor Force data. The job upgrade slowed, but did not come to a halt, during the Great Recession. We also document the labor market flows behind it: the complexity of jobs offered to new native hires was higher relative to the complexity of lost jobs. Finally, we find evidence that such reallocation was significantly larger in countries with more flexible labor laws and that his tendency was particularly strong for less educated workers

The Labor Market Impact of Immigration in Western Germany in the 1990's

In this article we measure the effects of recent immigration on the Western German labor market looking at both wage and employment effects. Refining administrative data for the period 1987-2001 to account for ethnic German immigrants and immigrants from Eastern Germany, we find that the substantial immigration of the 1990's had very little adverse effects on native wages and on their employment levels. Instead, it had a sizable adverse employment effect as well as a small adverse wage effect on previous waves of immigrants. These asymmetric results are partly driven by a higher degree of substitution between old and new immigrants in the labor market. In a simple calculation we show that the largest aggregate effect of new immigration on natives and old immigrants comes from the increased costs of unemployment benefits to old immigrants. Those costs could be eliminated in a world of wage flexibility and no unemployment insurance in which immigration would not have any negative employment effect but only moderate wage effects.International Migration, Remittances

Three-dimensional geometrical models of the inguinal region. Towards a new stereology

In this work we studied the inguinal-abdominal region and the inguinal canal using three-dimensional geometrical models. We built the models through computer aided geometric modeling techniques on the basis of observations during real dissections, operations and diagnostic medical imaging. The obtained models show in a complete modular synthesis and with a schematic iconology the structural organization of the anatomical districts in a logic sequence of layers and topographic and spatial relationships among its components. The models represent an amazing support to anatomy and clinical anatomy for teaching and research purposes on organogenesis, surgery and diagnosis

The synthetic glycolipid-based TLR4 antagonist FP7 negatively regulates in vitro and in vivo haematopoietic and non-haematopoietic vascular TLR4 signalling

TLRs, including TLR4, have been shown to play a crucial role in cardiovascular inflammatory-based diseases. The main goal of this study was to determine the potential of FP7, a synthetic glycolipid active as a TLR4 antagonist, to modulate haematopoietic and non-haematopoietic vascular TLR4 pro-inflammatory signalling. HUVEC, human THP-1 monocytes, THP-1-derived macrophages, mouse RAW-264.7 macrophages and Angiotensin II-infused apolipoprotein E-deficient mice were in vitro and in vivo models, respectively. Western blotting, Ab array and ELISA approaches were used to explore the effect of FP7 on TLR4 functional activity in response to bacterial LPS (in vitro) and endogenous ligands of sterile inflammation (in vitro and in vivo). Following activation of TLR4, in vitro and in vivo data revealed that FP7 inhibited p38 MAPK and p65 NF-kB phosphorylation associated with down-regulation of a number of TLR4-dependent pro-inflammatory proteins. In addition to inhibition of LPS-induced TLR4 signalling, FP7 negatively regulated TLR4 activation in response to ligands of sterile inflammation (hydroperoxide-rich oxidised LDL, in vitro and Angiotensin II infusion, in vivo). These results demonstrate the ability of FP7 to negatively regulate in vitro and in vivo haematopoietic and non-haematopoietic vascular TLR4 signalling both in humans and mice, suggesting the potential therapeutic use of this TLR4 antagonist for pharmacological intervention of vascular inflammatory diseases
