In a multiperiod setting, decision-makers can learn about the consequences of their decisions throughexperimentation. In this paper we examine how in a two-party system polarization and political instability affectlearning through experimentation. We distinguish two cases:the decision to be made...

We study the classical free-rider problem in public goods provision in a large economy with uncertainty about the average valuation of the public good. Individual preferences over public goods are shaped by a skill and a taste parameter. We use a mechanism design approach to solve for the...

We study experimentally the effectiveness of communication in common value committees exhibiting publicly known heterogeneous biases. We test models assuming respectively self-interested and strategic-, joint payoff-maximizing- and cognitively heterogeneous agents. These predict varying degrees...

We develop a model of strategic information transmission from an outside expert with informational superiority to a group of people who make a decision by voting on a proposal. An outside expert who observes the qualities of a proposal sends a cheap talk message to decision makers with limited...

We report the results of a laboratory experiment based on a citizen‐candidate model with private information about ideal points. Inefficient political polarization is observed in all treatments; that is, citizens with extreme ideal points enter as candidates more often than moderate citizens....

We develop a model of strategic information transmission from an expert with informational superiority to decision makers who vote on a proposal. We show that an expert's simple cheap talk strategy can be surprisingly effective in persuading decision makers by polarizing or unifying their...

This paper experimentally tests the effectiveness of three crowdsourced signaling mechanisms on their ability to resolve an asymmetric information problem over product quality for a set of consumers. Motivated by naturally occurring environments, the first mechanism allowed experimental subjects...

We investigate experimentally the effects of corrupt experts on information aggregation in committees. We find that non-experts are significantly less likely to delegate through abstention when there is a probability that experts are corrupt. Such decreased abstention when the probability of...

In a Bayesian persuasion setting, a sender persuades a receiver to take an action by designing and committing to disclose information about the receiver's payoff of taking the action. We propose a model that incorporates reciprocity into the Bayesian persuasion setting, using the approach of...

In a society composed of citizens and a dictator: what are the conditions for a successful citizens' revolt? What kind of strategies do governments follow to prevent such revolts? In this paper we argue that the concept of networks is a very powerful tool to understand these issues, as shown...
