We consider a random matching model where heterogeneous agents choose optimally to invest time and real resources in education. Generically, there is a steady state equilibrium where some agents, but not all of them, invest. Regular steady state equilibria are constrained inefficient in a...

We study a two-sector economy with investments in human and physical capital and imperfect labor markets. Human and physical capital are heterogeneous. Workers and firms endogenously select the sector they are active in and choose the amount of their sector-specific investments. To enter the...

Wir untersuchen den theoretischen Fall einer Ökonomie in der zwei verschiedene Ausbildungstypen in der Produktion verwendet werden. Die Arbeitskräfte sind heterogen in Hinblick auf ihre Fähigkeiten und selektieren sich durch unterschiedlich hohe Investitionen in Humankapital in einen der...

The paper studies a two-sector economy with investments in human and physical capital and imperfect labor markets. Workers and firms endogenously select the sector they are active in, and choose the amount of their investments. To enter the high-skill sector, workers must pay a fixed cost that...

There is plenty of individual-level evidence, based on the estimation of Mincerian equations, showing that better-educated individuals earn more. This is usually interpreted as a proof that education raises labour productivity. Some macroeconomists, analysing cross-country time series, also...

Consider an economy populated by males and females, both rich and poor. The society has to choose one of the following marriage institutions: polygyny, strict monogamy, and serial monogamy (divorce and remarriage). After having identified the conditions under which each of these equilibria...

This paper analyses the impact of networks on the structure of international migration flows to OECD countries. In particular, we look at whether diaspora effects are different across education levels and gender. Using new data allowing to include both dimensions, we are able to analyze the...

Relying on an original data set on international migration by educational attainment for 1990 and 2000, we analyze the determinants of the brain drain from developing countries. We start from a simple decomposition of the brain drain in two multiplicative components, the degree of openess of...
