Die wissensintensiven unternehmensnahen Dienstleistungen, die rund 8,5 Prozent zur der nominalen Wertschöpfung beitragen, sind in Deutschland der viertgrößte Wirtschaftszweig der gewerblichen Wirtschaft. Zudem gehören sie zu den Branchen mit den höchsten Beschäftigungszuwächsen. Die Arbeitsproduktivität in diesem Bereich ist zwischen 1995 und 2014 jedoch um über 40 Prozent gesunken. Erst danach erholt ...
We study the impact of broadband availability on firms’ total factor productivity (TFP) using German firm-level data between 2010 and 2015. We adopt a control function approach to causally identify and separately estimate productivity for 46 two-digit manufacturing and service sectors. Over the sample period, broadband availability, measured by 16 Mbps transmission rates, more than doubled in German ...
We extend standard models of work-related training by explicitly incorporating workers’ locus of control into the investment decision through the returns they expect. Our model predicts that higher internal control results in increased take-up of general, but not specific, training. This prediction is empirically validated using data from the German Socioeconomic Panel (SOEP). We provide empirical ...
In Germany, the productivity of professional services, a sector dominated by micro and small firms, declined by 40 percent between 1995 and 2014. This productivity decline also holds true for professional services in other European countries. Using a German firm-level dataset of 700,000 observations between 2003 and 2017, we analyze this largely uncovered phenomenon among professional services, the ...
