We hypothesize that incomplete integration into the workplace and society implies that immigrants are less likely to be union members than natives. Incomplete integration makes the usual mechanism for overcoming the collective action problem less effective. Our empirical analysis with data from the Socio-Economic Panel confirms a unionization gap for first-generation immigrants in Germany. Importantly, ...

The calibrated model offers a good fit to the empirical age profiles of search activity, job-finding rates, wages and savings, so that we ...

Home ownership status is closely linked to social inequality in Germany, where tenants face several disadvantages in multiple dimensions. Even though Germany is one of the biggest renter and therefore landlord nations, in the context of the housing question it is the demand side that has been discussed and studied most.

Respondents evaluated the fairness of their own incomes as well as the fairness of the incomes of the top and bottom income deciles in their countries. Depicted on a single graph, these income fairness evaluations take on a Z-shaped form, which we call the “inequity Z”. The inequity ...
