How does a monetary union alter the impact of business cycle shocks at the household level? We develop a Heterogeneous Agent New Keynesian model of two countries (HANK) and show in closed form that a monetary union shifts the adjustment to a shock horizontally across countries, within the brackets of the union-wide wealth distribution, rather than vertically, that is, across the brackets of the union-wide ...
Mats Kröger hat gute Ideen, um die Energiewende zu beschleunigen. Wenn Unternehmen jetzt immer mehr (sauberen!) Strom benötigen, weil sie ihre Produktion umstellen, dann brauchen sie auch Sicherheiten, was die Stromkosten angeht. Eine mögliche Lösung wäre ein sogenannter erneuerbare Energienpool, wo für beide Seiten, Stromproduzent*innen wie Stromkonsument*innen feste Preise garantiert werden...
Inexpensive and time-efficient web surveys have increasingly replaced survey interviews, especially conducted in person. Even well-known social surveys, such as the European Social Survey, follow this trend. However, web surveys suffer from low response rates and frequently struggle to assure that the data are of high quality. New advances in communication technology and artificial intelligence...
This paper addresses the pressing need for rapid decarbonization of energy systems by examining the role of nuclear power in future energy scenarios collected in the IPCC database. Despite their explorative character, energy scenarios can influence decision-makers or might be used to promote certain technology developments. They are increasingly subject to the integration into real-world settings and ...
Hochqualifizierte aus dem Ausland wollen selten nach Deutschland. Kommen sie doch, gehen viele schnell wieder. Und das, obwohl sie die soziale Sicherheit hier schätzen. Wieso scheitert Deutschland daran, mehr hoch qualifizierte Fachkräfte aus dem Ausland zu gewinnen? In der aufgeladenen Debatte um Zuwanderung behaupten manche, man müsse lediglich die Hürden für hoch qualifizierte Zugewanderte reduzieren ...
We study the impact of agglomeration effects on firms’ total factor productivity (TFP) for industry groups defined by technology intensity. This allows for non-uniform effects on firms depending on their technological level. We find that urban economies have the largest impact on firm productivity in high-technology industries, while they have no effectin low-technology industries. For firms in the ...
