Empiricism in the sciences allows us to test theories, formulate optimal policies, and learn how the world works. In this manner, it is critical that our empirical work provides accurate conclusions about underlying data patterns. False positives represent an especially important problem, as...

We conducted a fundraising experiment with an international development nonprofit organization in which a matching grant offered by the Bill and Melinda Gates Foundation raised more funds than one from an anonymous donor. The effect is strongest for solicitees who previously gave to other...

A large literature explores crowd out in situations where public goods are jointly provided; work in this area typically depicts a tax system where individuals take taxes as given. But in some settings, such as those in developing economies, efforts to evade or avoid taxes may be widespread. Using...

We design a laboratory experiment to investigate bilateral link formation in a setting where payoffs are pair-specific. Our link formation rule is decentralized and players can make link offers and counter-offers, as in a Beckerian marriage market. The game is designed in such a way that a...

The literature on voluntary provision of public goods includes recent theoretical work on the formation of voluntary coalitions to provide public goods. Theory is ambiguous on the equilibrium coalition size and contribution rates. We examine the emergence of coalitions, their size, and how...

Achieving efficiency for many global environmental problems requires voluntary cooperation among sovereign countries due to the public good nature of pollution abatement. The theory of international environmental agreements (IEAs) in economics seeks to understand how cooperation among countries...

Novel empirical insights by their very nature tend to be unanticipated, and in some cases at odds with the current state of knowledge on the topic. The mechanics of statistical inference suggest that such initial findings, even when robust and statistically significant within the study, should...

Nonprofit hospitals receive favorable tax treatment in exchange for providing socially beneficial activities. Extending this rationale would suggest that, insofar as suppression of competition would allow nonprofits to cross-subsidize care for needy populations, nonprofit hospital mergers should...

We present a new model of charitable giving where individuals regard out-of-pocket donations and the matches they induce as different. We show that match-price elasticities combine conventional price effects with the strength of warm-glow, so that a match-price elasticity alone is insufficient...

How can charities solicit high-capacity donors to provide the funds for matching grants and leadership gifts? In conjunction with one of Texas A&M University's fundraising organizations, we conducted a field experiment to study whether high-income donors respond to non-personal solicitations, as...
