Assessing the migration potential and predicting future migration streams are among the most relevant, yet least well understood topics of migration research. The usual approach taken to address aggregate-level prediction problems is to fit ad hoc specifications to historical data, and to...

In this paper, I study temporary migrations, and its consequences for immigrants' behaviour. I distinguish between temporary migrations where the return time is exogenous, and temporary migrations where the migrant chooses when to return. I then illustrate the consequences both types of...

Increased wage inequality between skilled and unskilled workers is a stylized fact, which can be observed in many developed countries. Among the explanations advanced for this phenomenon is the increasing globalization, a skill-biased technical progress, restructuring of the firms, and last but...

In recent years a number of panel estimators have been suggested for sample selection models, where both the selection equation and the equation of interest contain individual effects which are correlated with the explanatory variables. We review and compare some of these estimators, and apply...

Migration is an unavoidable aspect of globalization. While full flexibility is politically unfeasible, the paper argues for regulated openness. Migration in the age of globalization should be judged according to the labor market needs of the receiving countries. This would also serve best the...

This paper presents a life cycle model for the demand for health, and derives empirical specifications that distinguish between permanent and transitory wage responses. Using panel data, we estimate dynamic health and health input demand equations. We find evidence of negative transitory wage...
