Das wirtschaftspolitische Programm des künftigen US-Präsidenten Donald Trump ist schemenhaft und widersprüchlich. Zwei Punkte stechen bis jetzt heraus: Protektionismus und eine expansive Fiskalpolitik. Protektionismus würde einen langsameren Wachstumspfad für die US-amerikanische Wirtschaft implizieren, eine expansive Fiskalpolitik mit Steuersenkungen und einer starken Erhöhung der Infrastrukturausgaben würde, allerdings nur kurzfristig, das Gegenteil bedeuten.

The European Commission follows a harmonized approach for calculating structural (potential) output for EU member states that takes into account labor as an important ingredient. This paper shows how the recent huge migrants inflow to Europe affects trend output. Due to the fact that the immigrants immediately increase the working population but effectively do not enter the labor market, we illustrate that the potential output is potentially upward biased without any corrections. Taking Germany as an example, we find that the average medium-term potential growth rate is lower if the migration flow is modeled adequately compared to results based on the unadjusted European Commission procedure.

Die deutsche Wirtschaft befindet sich in einem verhaltenen Aufschwung. Die Kapazitätsauslastung hat im Frühjahr zugenommen, und im dritten Quartal 2015 dürfte die Veränderungsrate des Bruttoinlandsprodukts mit 0,5% leicht überdurchschnittlich ausfallen. Im weiteren Verlauf werden die Produktionskapazitäten wohl etwa normalausgelastet sein. Während die schwächere Nachfrage der Schwellenländer auf ein leichtes Abflachen der Exporte im späteren Jahresverlauf hindeutet, dürfte die inländische Nachfrage wieder stärker zulegen. Alles in allem wird das Bruttoinlandsprodukt im Jahr 2015 wohl um 1,8% zunehmen (66%-Prognoseintervall: 1,6% bis 2,0%).

The authors investigate immigrants’ and natives’ labor supply to the firm within an estimation approach based on a dynamic monopsony framework. Applying duration models that account for unobserved worker heterogeneity to a large administrative employer–employee data set for Germany, they find that immigrants supply labor less elastically to firms than do natives. Under monopsonistic wage setting, the estimated elasticity differential predicts a 7.7 log points wage penalty for immigrants thereby accounting for the entire unexplained native–immigrant wage differential of 5.8 to 8.2 log points. When further distinguishing immigrant groups differing in their time spent in the German labor market, their immigration cohort, and their age at entry, the authors find that the observed unexplained wage differential is larger for those groups that show a larger elasticity differential relative to natives. These findings not only suggest that search frictions are a likely cause of employers’ more pronounced monopsony power over their immigrant workers but also imply that employers profit from discriminating against immigrants.

Citizens of the German Democratic Republic (GDR) regained their civil liberties when the Berlin Wall fell 25 years ago. Since then, they have been able to travel freely and have been free to choose where to live and work. The fall of the Berlin Wall was quickly followed by preparations for German Unification at a speed unparalleled in history: the first free Volkskammer elections on 18 March 1990, the economic, monetary and social union on 1 July 1990, and finally, the unification of Germany when the GDR was included in the jurisdiction of the Basic Law of the Federal Republic of Germany. The integration of the economies of East and West Germany, however, has proven to be a drawn-out process.
