Political (self-)selection and competition: Evidence from U.S. Congressional elections

How does competition affect the entry and selection of politicians? I use data on U.S. Congressional primary and general elections for the years 1998-2014 to study this question. I measure quality using previous legislative experience and a measure of descriptive representation quantifying how well candidates represent their district demographically. To identify causal effects, I rely on variation in competition caused by decennial redistricting. Difference-in-differences estimates reveal differences between the electorally dominant and weak party. Experienced candidates and descriptively representative candidates enter relatively more frequently in primary elections in the weak party as competition increases. The reverse holds in the strong party. Both effects overall cancel out so that there are no effects on the quality of elected representatives. Investigating the mechanisms of the entry effect, I find that potential candidates respond to preferences of party members over valence, which play a larger role in competitive elections.

Favoritism towards high-status clubs: Evidence from German soccer

with Eberhard Feess and Helge Müller

(The Journal of Law, Economics, and Organization, Volume 38, Issue 2, July 2022, Pages 422–478, https://academic.oup.com/jleo/article-abstract/38/2/422/6355995)

Biases in legal decision making are difficult to identify as type II errors (wrongful acquittals) are hardly observable and type I errors (wrongful convictions) are only observed for the subsample of subsequently exonerated convicts. Our data on the first German soccer league allows us to classify each referee decision accurately as correct, type I error or type II error. The potential bias we are interested in is favoritism towards clubs with higher long-term status, proxied by the ranking in the all-time table at the beginning of each session and by membership. Higher-status clubs benefit largely from fewer type II errors. By contrast, the actual strength of clubs has no impact on referee decisions. We find no difference in type I errors and suggest anticipation of the bias as a potential explanation for the difference. We investigate several mechanisms potentially underlying our results; including career concerns and social pressure.
