"Empirical evidence for the US shows that migrants increase the productivity of regions. To explain the impact of migrants on the average firm productivity we construct a general equilibrium model with monopolistic competition a la Melitz (2003). We consider heterogeneous firms with different...

"The project has assessed whether a classification of secondary schools with regard to their success in leading school-leavers to an apprentice training or a comparable training scheme is possible. The approach intended to use the same methods as were used in the classification of regional...

"A casual look at regional unemployment rates reveals that there are vast differences which cannot be explained by different institutional settings. Our paper attempts to trace these differences in the regions' labour market performance back to the regions' specialisation in products that are...

L’effet de la dette publique sur l’investissement privé est théoriquement indéterminé. Ce lien peut aussi bien être négatif (debt overhang, effet d’éviction) que positif (effet accélérateur sur la croissance économique et donc sur l’investissement privé). Notre étude consiste...

In this paper, we provide a new empirical analysis of the dynamic portfolio decisions of households by simultaneously considering their stock market participation and home tenure choices. There is already a huge body of literature on housing status (own/rent) decisions and many contributions...

In many poor countries, the problem is not that governments do not invest, but that these investments do not create productive capital. So, the cost of public investments does not correspond to the value of the capital stocks. In this paper, we propose an original non parametric approach to...
