Dieser Text erschien am 14. September 2020 als Gastbeitrag in der Süddeutschen Zeitung., Ein dynamisches Gründungsgeschehen ist gerade in Krisenzeiten wünschenswert. Eines, das Wachstumsimpulse setzt, indem neu entstandene Marktlücken entdeckt und zukunftsweisende Innovationen geschaffen werden. Doch darauf können wir derzeit nur begrenzt hoffen. Die Covid-19-Krise trifft das ...
Durch den Nachfrageausfall in Folge der Corona-Krise haben viele Selbständige ihre Einkommensgrundlage – zumindest vorübergehend – teilweise oder sogar vollständig verloren. Rund 60 Prozent unter ihnen beklagen Einkommensverluste, während es bei den abhängig Beschäftigten etwa 15 Prozent sind. Rund die Hälfte der von der Krise negativ betroffenen...

I argue that the existence of the corporate income tax should be justified by the benefit-based view of taxation: firms should pay tax according to the benefits they receive from the use of the public input. I argue that...
Abstract: Antibiotic misuse due to prescribing under diagnostic uncertainty is a leading driver of antibiotic resistance. We investigate the magnitude and mechanisms by which machine learning predictions can enable policies that reduce antibiotic misuse. Building on predictions from administrative data on urinary tract infections in Denmark, we evaluate counterfactual policies that replace...
