"Theoretically, wage gaps between migrants and natives can be explained by human capital theory through either depreciation in human capital with migration or differences in endowments. However, even after considering human capital measures, an unexplained difference remains. We assume that...

"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...

"Two puzzling facts of international migration are that only a small share of a sending country's population emigrates and that net migration rates tend to cease over time. This paper addresses these issues in a migration model with heterogeneous agents that features temporary migration. In...

"Differences in regional labour market conditions are still pronounced in Germany, especially between the Eastern and the Western part. Traditional neoclassical models imply that labour mobility should reduce disparities. In contrast, models that include externalities or selective migration...

"We analyze the relation between population aging and the decline of unemployment in East Germany for the years from 1996 to 2012. To this we scrutinize both a direct and an indirect effect of aging on unemployment. The direct effect includes a decomposition of the East German unemployment rate...

"Socialist societies often emphasized the abolition of traditional social classes. To achieve this objective, educational opportunities were at times 'actively managed' and allocated to children of less educated parents. What happened to these patterns after the demise of socialist rule in...

"This paper provides a decomposition of the projected change in the overall labour force in East and West Germany into three parts. The first, called the 'demographic component', shows the effects of fertility, mortality and a changing age structure of the population. The second effect is the...

"Forecasts show a substantially decreasing and ageing labour force in Germany. This paper provides a decomposition of the projected change in the overall labour force into three parts. The first, called the 'demographic component', shows the effects of fertility, mortality and a changing age...
