Do experts adjust their policy recommendations when the facts change? We conduct a large-scale randomized experiment among 1,224 economic experts across 109 countries that includes two treatments. The first treatment is the geographic and temporal variation in the initial spread of Covid-19...

The electorates' lack of information about the extent of public spending may cause misalignments between voters' preferences and the size of government. We devise a series of representative survey experiments in Germany that randomly provide treatment groups with information on current spending...

How does a citizen's decision to participate in political activism depend on the participation of others? We conduct a nation-wide natural field experiment in collaboration with a major European party during a recent national election. In a seemingly unrelated survey, we randomly provide...

The impact of culture on non-kin cooperation has been singled out as critical for economic activity. However, causal evidence of culture's influence on cooperation remains scant. In this paper we provide such evidence, focusing on two key components of culture: preferences and beliefs. Adopting...

This paper provides experimental evidence on the electoral effect of a large education reform in a developing democracy. Despite significantly improving school quality, the policy reduced the incumbent party's presidential vote share by 3 percentage points (10%). This does not imply that voters...
