The Roy-Borjas model predicts that international migrants are less educated than nonmigrants because the returns to education are generally higher in developing (migrant-sending) than in developed (migrant-receiving) countries. However, empirical evidence often shows the opposite. Using the case of Mexico-U.S. migration, we show that this inconsistency between predictions and empirical evidence can be resolved when the human capital of migrants is assessed using a two-dimensional measure of occupational skills rather than by educational attainment. Thus, focusing on a single skill dimension when investigating migrant selection can lead to misleading conclusions about the underlying economic incentives and behavioral models of migration.

We analyse the impact of robot adoption on employment composition using novel micro data on robot use in German manufacturing plants linked with social security records and data on job tasks. Our task-based model predicts more favourable employment effects for the least routine-task intensive occupations and for young workers, with the latter being better at adapting to change. An event-study analysis of robot adoption confirms both predictions. We do not find adverse employment effects for any occupational or age group, but churning among low-skilled workers rises sharply. We conclude that the displacement effect of robots is occupation biased but age neutral, whereas the reinstatement effect is age biased and benefits young workers most.

Der „umgekehrte Drehtüreffekt“ beschreibt das Phänomen, wenn ehemalige Bankerinnen und Banker Vorstandspositionen in nationalen Aufsichtsbehörden (National Supervisory Agency, NSA) bekleiden. Ein neu erhobener Datensatz zeigt, dass etwa ein Drittel der Vorstandsmitglieder in europäischen NSA vorher in der Finanzindustrie tätig war. Die Bestellung ehemaliger Banker in NSA-Vorstände geht mit positiven Börsenreaktionen einher, was auf eine „Näheprämie“ in der Bewertung beaufsichtigter Banken hindeutet. Im Gegensatz dazu ruft die Berufung von Bürokraten ohne praktische Vorkenntnisse in der Bankenwelt negative Börsenreaktionen hervor. Bis zur Einführung des Einheitlichen Aufsichtsmechanismus (Single Supervisory Mechanism, SSM) in Europa korreliert die Präsenz ehemaliger Banker in NSA-Vorständen mit einer geringeren regulatorischen Kapitalquote, was auf einen nachsichtigeren Aufsichtsstil schließen lässt.

Establishment closures have lasting negative consequences for the workers displaced from their jobs. We study how these consequences vary with the amount of skill mismatch that workers experience after job displacement. Developing new measures of occupational skill redundancy and skill shortage, we analyze the work histories of individuals in Germany between 1975 and 2010. We estimate difference-in-differences models, using a sample of displaced workers who are matched to statistically similar non-displaced workers. We find that displacements increase the probability of occupation change eleven-fold. Moreover, the magnitude of post-displacement earnings losses strongly depends on the type of skill mismatch that workers experience in such job switches. Whereas skill shortages are associated with relatively quick returns to the earnings trajectories that displaced workers would have experienced absent displacement, skill redundancy sets displaced workers on paths with permanently lower earnings. We show that these differences can be attributed to differences in mismatch after displacement, and not to intrinsic differences between workers making different post-displacement career choices.
