This paper estimates a theory-guided gravity equation of regional patient ows. In our model, a patient's choice to consult a physician in a particular region depends on a measure of spatial accessibility that accounts for the exact locations of both patients and physicians. Introducing this...

This paper introduces quality innovations with endogenous sunk costs in a heterogeneous firm model of international trade and derives implications for the gravity equation. The model predicts that the effect of fixed costs on exports and on the share of exporters is lower in industries with a...

Die Studie befasst sich mit den Auswirkungen der Russland-Sanktionen auf den Außenhandel und die Wertschöpfung Deutschlands, Russlands und der Europäischen Union (EU). Neben einer deskriptiven Analyse werden mithilfe ökonometrischer Methoden die Effekte der verschiedenen Sanktionsregime...

Diese Studie befasst sich mit der Quantifizierung der ökonomischen Auswirkungen des Austritts des Vereinigten Königreichs (VK) aus der Europäischen Union (EU) ("Brexit") auf die deutsche und europäische Wirtschaft. Seit dem Brexit-Referendum vom 23. Juni 2016 herrscht über die Zukunft der...
