|December 2019||Social Media and Xenophobia: Evidence from Russia|
with Leonardo Bursztyn, Georgy Egorov, Maria Petrova: w26567
We study the causal effect of social media on ethnic hate crimes and xenophobic attitudes in Russia using quasi-exogenous variation in social media penetration across cities. Higher penetration of social media led to more ethnic hate crimes, but only in cities with a high pre-existing level of nationalist sentiment. Consistent with a mechanism of coordination of crimes, the effects are stronger for crimes with multiple perpetrators. We implement a national survey experiment and show that social media persuaded young and low-educated individuals to hold more xenophobic attitudes, but did not increase respondents' openness to expressing these views. Our results are consistent with a simple model of social learning where penetration of social networks increases individuals' propensity to mee...
|May 2014||Electoral Rules and the Quality of Politicians: Theory and Evidence from a Field Experiment in Afghanistan|
with Andrew Beath, Fotini Christia, Georgy Egorov: w20082
We examine the effect of electoral rules on the quality of elected officials using a unique field experiment which induced randomized variation in the method of council elections in 250 villages in Afghanistan. In particular, we compare at-large elections, with a single multi-member district, to district elections, with multiple single member districts. We propose a theoretical model where the difference in the quality of elected officials between the two electoral systems occurs because elected legislators have to bargain over policy, which induces citizens in district elections to vote strategically for candidates with more polarized policy positions even at the expense of candidates' competence. Consistent with the predictions of the model, we find that elected officials in at-large ele...

with Stefano DellaVigna, Vera Mironova, Maria Petrova, Ekaterina Zhuravskaya: w16989
How do nationalistic media affect animosity between ethnic groups? We consider one of Europe's deadliest conflicts since WWII: the Serbo-Croatian conflict. We show that, after a decade of peace, cross-border nationalistic Serbian radio triggers ethnic hatred towards Serbs in Croatia. Mostly attracted by non-political content, many Croats listen to Serbian public radio (intended for Serbs in Serbia) whenever signal is available. As a result, the vote for extreme nationalist parties is higher, and ethnically offensive graffiti are more common, in Croatian villages with Serbian radio reception. A laboratory experiment confirms that Serbian radio exposure causes anti-Serbian sentiment among Croats.
