"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...

"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 consider an economy where production may use labor of two different skill levels. Workers are heterogeneous and, by investing in education, self-select into one of the two skills. Ex-ante, when firms choose their investments in physical capital, they do not know the level of human capital...

"By arranging the Microcensus (the German Labour Force Survey) as a set of panel data it is possible to carry out longitudinal analyses. As participation in the survey is obligatory by law, the cases of non-response are minimal. For that reason the number of cases available is comparably high,...

"This article examines if occupations contribute to social closure by their structural characteristics. For this purpose the four structural indicators occupational specificity, standardization by training regulation, voluntary certification by private educ-tional providers and representation by...

"Most models on centralization in wage setting rest on the assumption of identical firms. This stands in sharp contrast to informal statements against centralization wich rest on the argument that firms are heterogenous and that equal treatment of firms by unions must therefore be ineffcient. We...

"Kombilöhne sind staatliche Transferzahlungen an Arbeitnehmer, die an die Aufnahme einer abhängigen, sozialversicherungspflichtigen Beschäftigung unterhalb einer bestimmten Lohnhöhe gebunden sind. Ziel ist u.a. die dauerhafte Reintegration wettbewerbsschwacher Arbeitsloser in...
