Collective action is a dynamic process where individuals in a group assess over time the benefits and costs of participating toward the success of a collective goal. Early participation improves the expectation of success and thus stimulates the subsequent participation of other individuals who...

We study a standard collective action problem in which successful achievement of a group interest requires costly participation by some fraction of its members. How should we model the internal organization of these groups when there is asymmetric information about the preferences of their...

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...

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 estimate whether federal aid for state and local governments played a role in advancing population testing for COVID-19 and the administration of vaccines. To overcome biases that can result from the endogeneity of federal aid allocations, we use an instrumental-variables estimator reliant on...

A classic problem in public finance is the over-expenditure of local governments in expectation of a bailout from higher-level administrations. While monitoring could mitigate agency problems, it can itself be rendered ineffective if auditors are corruptible. I evaluate whether limiting...

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 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...
