Price dispersion in simultaneous online auctions is a puzzle in light of the relatively low search costs required to find the lower price. Much of this price dispersion appears to be due to lack of switching by bidders between auctions, which in turn could be due to inertia related to search...

Given the substantial amount of resources currently invested in microcredit programs, it is more important than ever to accurately assess the extent to which peer monitoring by borrowers faced with group liability contracts actually reduces moral hazard. We conduct a field experiment with women...

A number of development assistance programs promote community interaction as a means of building social capital. Yet, despite strong theoretical underpinnings, the role of repeat interactions in sustaining cooperation has proven difficult to identify empirically. We provide the first...

Urban peripheries in many developing country cities lack basic local public goods like pavement, water, sewerage and electricity. We estimate the impacts of slum infrastructure upgrading using an experiment in urban road pavement provision in Mexico. Our findings show that homes in streets that...

As technology has advanced, many have wondered whether (or simply when) artificial intelligent devices will replace the humans who perform complex, interactive, interpersonal tasks such as dispute resolution. Has science now progressed to the point that artificial intelligence devices can...

We link two important ideas: attention is scarce and a lack of information about an individual drives discrimination in selection decisions. We model how knowledge of ethnicity influences allocation of attention to available information about an applicant. When only a small share of applicants...

Tax evasion is a pervasive problem in many countries. In particular, some developing countries do not collect even half of what they would if taxpayers complied with the written letter of the law. The academic literature has not been oblivious to the need to explain why people pay (or do not...

We conducted a field experiment involving 720 Italian undergraduate students to investigate the existence of gender differences in performance in competitive settings and whether performance is affected by one's opponent gender. The experimental design was aimed at disentangling gender...

We conduct an artefactual field experiment to study whether the individual preferences and propensity to cooperate of temporary workers differ from permanent contract workers. We find that temporary and permanent contract workers have different other-regarding preferences, but display similar...

Using a field experiment, we investigate whether discrimination based on women's sexual orientation differs by age and family constraints. We find weakly significant evidence of discrimination against young heterosexual women. This effect is driven by age (and fertility) rather than by...
