This paper compares two methods to encourage socially optimal provision of a public good. We compare the efficacy of vigilante justice, as represented by peer-to-peer punishment, to delegated policing, as represented by the "hired gun" mechanism, to deter free riding and improve group welfare....

We present and experimentally test a mechanism that provides a simple, natural, low cost, and realistic solution to the problem of compliance with socially determined efficient actions, such as contributing to a public good. We note that small self-governing organizations often place enforcement...

When public goods can only be provided when donations cross a minimum threshold, this creates an advantage in that Pareto Efficient outcomes can be Nash Equililibria. Despite this, experiments have shown that the groups struggle to coordinate on one of the many efficient equilibria. We apply a...

New laws such as salary history bans aim to reduce historical inequalities by limiting the information employers can seek. Although employers are forbidden from asking, workers are free to disclose information voluntarily. We study the impact of the ban through the novel lens of unravelling and...

This paper presents the results from a 2.3 million person field experiment that varies whether or not a job seeker sees the number of applicants for a job posting on a large job posting website, LinkedIn. This intervention increases the likelihood that a person will finish an application by...

We study how salary history disclosures affect employer demand, and how salary history bans shape hiring and wages. We show how these effects depend on the properties of the labor market, and we measure the key properties using a novel, two-sided field experiment. Our field experiment features...

In this paper, we contribute to the debate on the determinants of redistribution policies and provide evidence that the source of income – whether income is earned through work as opposed to determined by luck – does not only affect the level of redistribution, but also the relationship...

The ability to punish free-riders can increase the provision of public goods. However, sometimes the benefit of increased public good provision is outweighed by the costs of punishments. One reason a group may punish to the point that net welfare is reduced is that punishment can express anger...

A popular fundraising tool is donation matching, where every dollar is matched by a third party. But field experiments find that matching does not always increase donations. This may occur because individuals believe that peer donors will exhaust the matching funds, so their donation is not...

How do households view contributions of time (via volunteering/fundraising) to their children's schools? Time contributions produce a public good (improved school quality for all students) and private benefits (e.g., better class placement). If private benefits increase with number of own...
