We propose a formal model of small campaign contributions driven by an electoral motive, that is, by the possible influence of contributions on the outcome of an election. Electoral considerations produce strategic interactions among contributors, even when each donor takes as given the actions...

This paper studies the manipulation of electoral maps by political parties, known as gerrymandering. At the core of our analysis is the recognition that districts must have the same population size but only voters matter for electoral incentives. Using a novel model of gerrymandering that allows...

This paper studies voting in shareholders meetings. We focus on the informational efficiency of different voting mechanisms, taking into account that they affect both management's incentives before the meeting and shareholders' decisions at the meeting. We first focus on the case in which the...

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 study experimentally the properties of the majority runoff system and compare them to the ones of plurality rule, in the setup of a divided majority. Our focus is on Duverger's famous predictions that the plurality rule leads to a higher coordination of votes on a limited number of candidates...

We study the properties of the group-based model of voting in elections with more than two candidates. We consider two of the most widely used electoral rules around the world: plurality and majority runoff. We fully characterize the set of equilibria under both rules and identify the features...

This paper presents a dynamic political-economic model of total government obligations. Its focus is on the interplay between debt and entitlements. In our model, both are tools by which temporarily powerful groups can extract resources from groups that will be powerful in the future: debt...

We study the information aggregation properties of unanimous voting rules in the laboratory. In line with theoretical predictions, we find that majority rule with veto power dominates unanimity rule. We also find that the strategic voting model is a fairly good predictor of observed subject...

Rankings have become increasingly popular on various markets, e.g. the market for study programs. We analyze their welfare implications. Consumers have to choose between two goods of unknown quality with exogenous presence or absence of an unbiased informative ranking. The existence of the...

A group of agents wants to reform the status quo if and only if this is Pareto improving. Agents have private information and may have common or private objectives, which creates a tension between information aggregation and minority protection. We analyze a simple voting system - majority rule...
