Profil

Zusammenfassung

Prof. Hager erforscht, wie politische Einstellungen und Verhalten entstehen und sich verändern — insbesondere wie öffentliche Meinung Politikerinnen beeinflusst, wie Bürgerinnen sich an Protesten beteiligen, und welche Faktoren Wählerpräferenzen prägen. Er nutzt dafür Feldexperimente, Umfragen und historische Daten, um kausale Zusammenhänge nachzuweisen. Seine Erkenntnisse sind für Organisationen relevant, die verstehen wollen, wie politische Mobilisierung, Meinungsbildung und Wahlverhalten funktionieren.

• Does Public Opinion Affect Political Speech?

  2020

  American Journal of Political Science · 101 Zitationen · DOI

  Abstract Does public opinion affect political speech? Of particular interest is whether public opinion affects (i) what topics politicians address and (ii) what positions they endorse. We present evidence from Germany where the government was recently forced to declassify its public opinion research, allowing us to link the content of the research to subsequent speeches. Our causal identification strategy exploits the exogenous timing of the research's dissemination to cabinet members within a window of a few days. We find that exposure to public opinion research leads politicians to markedly change their speech. First, we show that linguistic similarity between political speech and public opinion research increases significantly after reports are passed on to the cabinet, suggesting that politicians change the topics they address. Second, we demonstrate that exposure to public opinion research alters politicians' substantive positions in the direction of majority opinion.

• Does State Repression Spark Protests? Evidence from Secret Police Surveillance in Communist Poland

  2021

  American Political Science Review · 63 Zitationen · DOI

  Does physical surveillance hinder or foster antiregime resistance? A common view holds that surveillance prevents resistance by providing regimes with high-quality intelligence on dissident networks and by instilling fear in citizens. We contrast this view using formerly classified data from Communist Poland. We find that communities exposed to secret police officers were more likely to organize protests but also engaged in less sabotage. To ensure that the relationship is causal, we use an instrumental variable strategy, which exploits the exogenous assignment of Catholic “spy priests” to local communities. To trace the underlying mechanisms, we draw on qualitative interviews and archival sources. We document that Poland’s comprehensive use of surveillance created widespread anger as well as an incentive for citizens to reveal their true loyalties, thus facilitating antiregime collective action. Once on the streets, protesters refrained from sabotage to signal their political motivation to bystanders and authorities alike.

• Ethnic Riots and Prosocial Behavior: Evidence from Kyrgyzstan

  2019

  American Political Science Review · 60 Zitationen · DOI

  Do ethnic riots affect prosocial behavior? A common view among scholars of ethnic violence is that riots increase cooperation within the warring groups, while cooperation across groups is reduced. We revisit this hypothesis by studying the aftermath of the 2010 Osh riot in Kyrgyzstan, which saw Kyrgyz from outside the city kill over 400 Uzbeks. We implement a representative survey, which includes unobtrusive experimental measures of prosocial behavior. Our causal identification strategy exploits variation in the distance of neighborhoods to armored military vehicles, which were instrumental in orchestrating the riot. We find that victimized neighborhoods show substantially lower levels of prosocial behavior. Importantly, we demonstrate that the reduction is similarly stark both within and across groups. Using qualitative interviews, we parse out two mechanisms that help explain the surprising reduction in ingroup prosociality: Victimized Uzbeks felt abandoned by their coethnics, and variation in victimization created a feeling of suspicion.
