We investigate in an economic experiment how people choose sides in disputes. In an eight-player side-taking game, two disputants at a time fight over an indivisible resource and other group members choose sides. The player with more supporters wins the resource, which is worth real money....

In recent years, concerns about misinformation in the media have skyrocketed. President Donald Trump has repeatedly claimed that various news outlets are disseminating "fake news" for political purposes. But when the information contained in mainstream media news reports provides no clear clues...

Time preferences vary by age. Notably, according to experimental studies, senior citizens tend to discount future payoffs more heavily than working-age individuals. Based on these findings, we hypothesize that demographic change has contributed to the cut-back in government-financed investment...

Allegations of voter fraud accompany many real-world elections. How does electoral malpractice affect the acceptance of elected institutions? Using an online experiment in which people distribute income according to majority-elected rules, we show that those who experience vote buying or voter...

We investigate the relationship between political attitudes and prosociality in a survey of a representative sample of the U.S. population during the first summer of the COVID-19 pandemic. We find that an experimental measure of prosociality correlates positively with adherence to protective...

How do voters react to large shocks that are (mostly) outside the control of politicians? We address this question by studying the electoral effects of wildfires in Spain during 1983-2011. Using a difference-in-difference strategy, we find that a large accidental fire up to nine months ahead of...

We exploit a large exogenous shock to study the determinants of college attendance and the role played by one's environment. We analyze whether, and how quickly, adolescents' college plans are adapted, explore factors leading to the adjustment, and examine how these factors ultimately impact...

This paper investigates how voters respond to threats to the nation by estimating the political effects of the Cuban Missile Crisis. To establish causality, I exploit the geographical variation induced by the range of the missiles: only U.S. localities within 1,000 nautical miles from Cuba could...

Recent increases in political polarization in social media raise questions about the relationship between negative online messages and the decline in political trust around the world. To evaluate this claim causally, we implement a variant of the well-known trust game in a survey experiment with...

Does poor air quality affect decision-making? We study this question based on elections, in which millions of people decide on the same issue on the same day in different locations. We use county-level data from 64 federal and state elections in Germany over a nineteen-year period and exploit...
