Im Zuge der Corona-Pandemie hat der Einzelhandel den Einsatz von non-cash Einzelhandel vorangetrieben. Um eine Covid-Ansteckung zu verhindern, werden Kund*innen gebeten bargeldlos zu zahlen. Tatsächlich es gibt zwischen einzelnen Volkswirtschaften große Unterschiede in der Verwendung von Bargeld und bargeldlosen Zahlungen. Im Beitrag wird empirisch der Frage nachgegangen, welche Faktoren hinter diesen ...
Worldwide, the overwhelming majority of large horizontal mergers are cleared by antitrust authorities unconditionally. The presumption seems to be that efficiencies from these mergers are sizeable. We calculate the compensating efficiencies that would prevent a merger from harming consumers for 1,014 mergers affecting 12,325 antitrust markets scrutinized by the European Commission between 1990 and ...
We study the determinants of common European merger policy over its first 25 years, from 1990 to 2014. Using a novel dataset at the level of the relevant antitrust markets and containing all relevant merger cases notified to the European Commission, we evaluate how consistently arguments related to structural market parameters – dominance, rising concentration, barriers to entry, and foreclosure – ...
As the German economy and the EU are emerging from the COVID-19 pandemic, the focus is shifting to questions of long-term transformation. How can we transform our economies while also limiting climate change and preparing for its impact? The pandemic has accelerated digitalization of German firms and many have already invested to deal with climate change. At the same time, concerns about the...
We quantify labour market effects of changes in the potential benefit duration (PBD) in Poland. Individual workers' PBD depends on the county unemployment rate relative to the national average---12 months of PBD above a cut-off of 125 per cent and 6 months below. This cut-off shifted from 125 to 150 per cent in a 2009 reform. We utilize (i) the natural experiment of the reform and (ii) the...
We investigate how internal distribution motives can interfere with the economic objectives of capital controls. In order to do this, we provide a model showing that elite capture can affect optimal debt repatriations and the management of official reserves under capital controls. Relying on these theoretical insights and a wealth of quantitative and qualitative historical evidence, we study one of ...
With the closure of the final six nuclear power plants, the commercial use of nuclear energy for electricity generation in Germany will come to an end in 2022. Due to the German power system's sufficient capacities—in 2020, the sector exported 20 terawatt hours (TWh), or about four percent of its electricity production—and its integration into the European electricity system, there is no reason to ...
