- 🚨New working paper: Compositional Effects, Internal Migration and Electoral Outcomes osf.io/preprints/so... #polisciresearch
- When studying how internal migration affects changes in district-level electoral outcomes, it is important to separate the compositional effect (heterogeneity in political behavior between movers and stayers) from the exposure effect (change in political behavior due to exposure to migration).
- We use Rubin's potential outcomes framework to formally define compositional effects and to decompose the total causal effect of internal migration into exposure effects and compositional effects.

View full threadWe demonstrate that there is a compositional effect: using survey data, we show that leavers were 18 pp less likely to support the incumbent than stayers. Thus, in constituencies with more out-migration, the incumbent vote share increased.

- 1/ Over 1 million refugees arrived in Germany in 2015. When established language training programs ("Integrationskurse") reached capacity, the Federal Employment Agency swiftly launched a new ad hoc program ("Einstiegskurse zur Deutschförderung") to enroll more.

- Reposted by Moritz Marbach📜Using a game-theoretic model, @moritzmarbach.bsky.social & C. M. Horz show that restrictive asylum policies also raise the credibility of applicants’ claims to political persecution and, therefore, may not decrease the number of admitted refugees www.cambridge.org/core/journal... #FirstView
