In simple static models, migration increases with the wage differential between host and home country. In a dynamic framework, and if migrations are temporary, the size of the migrant population in the host country depends also on the migration duration. This paper analyses optimal migration...

If migrants return to their origin countries, two questions arise which are of immediate economic interest for both immigration and emigration country: What determines their optimal migration duration, and what are the activities migrants choose after a return. Little research has been devoted...

This paper contrasts labour participation behaviour and wages of native and immigrant women. Since the impact of family structure on labor supply differs between natives and immigrants, we explicitly distinguish between part-time and full-time jobs. The choice of jobs is accounted for by an...

Hostility towards minorities may sometimes have economic rather than racial motives. Labour market fears, or concerns about the welfare system, are often believed to manifest themselves in hostile attitudes towards population groups that are considered to be competitors for these resources. The...

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...

We analyze a general search model with on-the-job search and sorting of heterogeneous workers into heterogeneous jobs. This model yields a simple relationship between (i) the unemployment rate, (ii) the value of non-market time, and (iii) the max-mean wage differential. The latter measure of...

We argue in favor of the shareholder model of the firm for three main reasons. First, serving multiple stakeholders leads to ill-defined property rights. What sounds like a fair compromise between stakeholders can easily evolve in a permanent struggle about the ultimate goal of the company....

In this paper we analyse the short- and long-run relationship between employment growth, inflation and output growth in Phillips' tradition. For this purpose we apply FMOLS, DOLS, PMGE, MGE, DFE, and VECM methods to a nonstationary heterogeneous dynamic panel including annual data for 119...
