One of the most important long-run trends in the U.S. labor market is polarization, defined as the relative growth of employment in high-skill jobs (such as management and technical positions) and low-skill jobs (such as food-service and janitorial work) amid the concurrent decline in...

Many large urban school districts are rethinking their personnel management strategies, often giving increased control to schools in the hiring of teachers, reducing, for example, the importance of seniority. If school hiring authorities are able to make good decisions about whom to hire, these...

In the demographic change, a prolongation of individual employment and thus of beginning a new employment in later stages of the work life is of growing importance. On the base of microeconomic data (establishment panel of the IAB), this paper analyses firms’ characteristics correlating with...

A model of the labour market under firing restrictions and endogenous quits is constructed. It is shown that in the spirit of Blanchard and Summers (1988), the model can generate multiple equilibria, with a low-quits/high-unemployment equilibrium coexisting with a high-quits/low-unemployment...

The paper analyses complementarities among a variety of labour market policies. It shows: (a) that a wide range of labour market institutions (e.g. unemployment benefits, job security legislation and payroll taxes) have complementary effects on unemployment; and thus (b) that policies aimed at...

Job losses during the Great Recession were concentrated among middle-skill workers, the same group that over the long run has suffered the most from automation and international trade. How might long-run occupational polarization be related to cyclical changes in middle-skill employment? We find...

Der Diskussion um neue Arbeitszeitarrangements und flexible Arbeitszeiten fehlt bislang die empirische Grundlage auf der Basis von personenbezogenen Mikrodaten. Gegenstand unserer Studie Arbeit ist es, Abweichungen vom Normalarbeitstag in zwei Dimensionen zu untersuchen: zum einen in der...
