In this paper we investigate how heterogeneous agents choose among tournaments with different prizes. We show that if the number of agents is sufficiently small, multiple equilibria can arise. Depending on how the prize money is split over the tournaments, these may include, for example, a...

Staggered difference-in-differences designs are pervasive in policy evaluations but little is known about the mechanisms of policy diffusion: How and why do such policies spread across jurisdictions? In this study, we highlight the role of elections in policy diffusion in settings where...

We investigate the matching algorithm used by the German central clearinghouse for university admissions (ZVS) in medicine and related subjects. This mechanism consists of three procedures based on final grades from school ("Abiturbestenverfahren", "Auswahlverfahren der Hochschulen") and on...

This paper studies the productivity effects of integration deepening. The identification strategy exploits the 1995 European Union (EU) enlargement, when all candidate countries joined the Single Market but one â Norway â did not join the EU. Our synthetic difference-in-differences estimates...

Some of the member states of the European Union sell citizenship or residence to wealthy foreign investors. We analyse these "golden-passport" programs as a study in the political economy of conflict and cooperation in an international meta-club. Seen through the lens of club goods theory, the...

The robust empirical finding that exporting firms are systematically different from firms thatmerely serve domestic consumers has inspired the development of a new brand of tradetheory, the theory of heterogeneous firms and trade. The establishment of a canonical modeldue to Melitz (2003) has...

Our paper deals with econometric developments for the estimation of the gravity model whichlead to convergent parameter estimates even when a correlation exists between theexplanatory variables and the specific unobservable characteristics of each unit. Weimplement panel data econometric...

The risk of default that business firms face is very significant and differs widely across countries. This paper explores the links between countries' business conditions and international trade embedment and the default risk at the country level from a theoretical point of view. Our main...

This paper explores the role of country asymmetries for trade and industrial policies with heterogeneous firms. Our analysis delivers a number of novel results. First, trade policies, infrastructure policies and industrial policies which improve the business conditions in one country have...
