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...

Voluntary social distancing plays a vital role in containing the spread of the disease during a pandemic. As a public good, it should be more commonplace in more homogeneous and altruistic societies. However, for healthy people, observing social distancing has private benefits, too. If sick...

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...

We provide evidence that individuals substitute between political contributions and charitable contributions, using micro data from the American Red Cross and Federal Election Commission. First, in a lab experiment, we show that information on the importance of charitable giving increases...

We analyze under which conditions intermarriage can be used as an indicator of tolerance, and whether such tolerant attitudes persisted in Germany during the last century. We find strong evidence for the persistence of tolerant attitudes towards intermarriage with Jews. At the same time, our...

Can autocracies win electoral support by showcasing economic competence? We analyze a famous case – the building of the Autobahn network in Nazi Germany. Using newly collected data, we show that highway construction was effective in boosting popular support, helping to entrench the Nazi...

Why did the country that borrowed the most industrialize first? Earlier research has viewed the explosion of debt in 18th century Britain as either detrimental, or as neutral for economic growth. In this paper, we argue instead that Britain's borrowing boom was beneficial. The massive issuance...
