How does lie detection constrain the potential for one person to persuade another to change her action? We consider a model of Bayesian persuasion in which the Receiver can detect lies with positive probability. We show that the Sender lies more when the lie detection probability increases. As...

Many, if not most, personalistic dictatorships end up with a disastrous decision such as Hitler's attack on the Soviet Union, Hirohito's government launching a war against the United States, or Putin's invasion of Ukraine in February 2022. Even if the decision is not ultimately fatal for the...

We study how beliefs about firm value respond to public information stemming from either public announcements or shareholder meetings. We focus on settings with homogeneous shareholders (i.e., agents with common preferences and opinions), where information is about which course of action is best...

We propose a general equilibrium model where two special interest groups (SIGs) compete to influence public opinion. Citizens with heterogeneous priors over a binary state of the world receive reports drawn from a continuous message space by a variety of sources. The two opposite SIGs attempt to...

We analyze a model of political competition in which the elite forms endogenously to aggregate information and advise the uninformed median voter which candidate to choose. The median voter knows whether or not the endorsed candidate is biased toward the elites, but might still prefer the biased...

The FDA is responsible for the approval of new drugs, biological products and medical devices in the United States. As part of the approval process, the FDA relies on advisory committees, which provide independent advice from outside experts. We combine a structural approach with newly collected...

I study how people understand and reason about trade and which factors shape their views on trade policy. I design and run large-scale surveys and experiments in the U.S. to elicit respondents' knowledge and understanding of trade. I also ask about their perceived economic gains and...

We study the characteristics and behavior of small campaign donors and compare them to large donors by building a dataset including all the 340 million individual contributions reported to the U.S. Federal Election Commission between 2005 and 2020. Thanks to the reporting requirements of online...

We exploit a natural experiment to study the extent to which popular attitudes toward trade are driven by economic fundamentals. In 2007, Costa Rica put a free trade agreement (FTA) to a national referendum. With a single question on the ballot, 59% of Costa Rican adult citizens cast a vote on...

We review the growing literature on the political economy of immigration. First, we discuss the effects of immigration on a wide range of political and social outcomes. The existing evidence suggests that immigrants often, but not always, trigger backlash, increasing support for anti-immigrant...
