We evaluate the determinants of aggregate matching efficiency changes through a stochastic Cobb-Douglas production frontier model. The efficiency coefficient is represented by a stochastic function of variables meant to capture workers and firms characteristics. The model is estimated on French...

Using a new data set that allows us to analyze precisely the research output in all fields of science, we show that the gap in scientific performance between Europe, especially continental Europe, and Anglo-Saxon countries, especially the USA, is large. We measure research quality by the number...

As has been found in previous studies, the labor market performance of individuals is often affected by demographic determinants like cohort size, age, marriage status and family size. While most of this analysis was studied for earnings, the paper investigates the issue for labor mobility....

François Laisney, Michael Lechner and Winfried Pohlmeier This paper presents an extension of Chamberlain's approach to modelling correlated random effects in a dichotomous model estimated on panel data. The extension consists in relaxing the arbitrary normality assumption made on all error...

Early retirement is often explained as resulting from a voluntary labour supply choice of a utility maximizing individual. nonetheless, a lof of individuals perceive retirement as a forced instead as a voluntary decision. This paper tries to accomodate voluntary and unvoluntary labour supply...

This paper proposes to investigate the effect of spillovers on location decision of firms. We develop an analysis merging the geographer toolbox with the standard econometric techniques. For a chosen sample of sectors, through the spatial data analysis, we test the existence of positive spatial...

We investigate the relationship between remittances and migrants' education both theoretically and empirically, using original bilateral remittance data. At a theoretical level we lay out a simple model of remittances interacting migrants' human capital with two dimensions of immigration policy:...

The paper investigates the link between the over-exposure of African immigrants to unemployment in France and their under-representation in jobs in contact with customers. We build a two-sector matching model with ethnic sector-specifc preferences, economy-wide employer discrimination, and...

This paper takes advantage of the availability of rich panel data on the mobility of talented football players, and the performances of national leagues and teams to quantify the effect of the reduction in mobility restrictions, the 1995 Bosman rule, on global efficiency and cross-country...

This paper studies equilibrium unemployment in a two-region economy where homogeneous workers and jobs are free to move and the housing market clears. Because of the Internet, searching for a job in another region without first migrating there is nowadays much simpler than in the past....
