We report on a field experiment providing random grants to microenterprise owners. The grants generated large profit increases for male owners, but not for female owners. We show that the gender gap does not simply mask differences in ability, risk aversion, entrepreneurial attitudes, or differences in reporting behavior, but there is some evidence that the(More)
We investigate the relationship between violence and economic risk preferences in Afghanistan combining: (i) a two-part experimental procedure identifying risk preferences, violations of Expected Utility, and specific preferences for certainty; (ii) controlled recollection of fear based on established methods from psychology; and (iii) administrative(More)
We use a combination of detailed panel data and a randomized experiment to assess the role of capital in the recovery process of microenterprises in Sri Lanka following the December 2004 tsunami. Disaster relief in low-income countries typically comes in the form of relief aid rather than insurance payments. In our data aid is found to be uncorrelated with(More)
What explains local variation in electoral manipulation in countries with ongoing internal conflict? The theory of election fraud developed in this article relies on the candidates' loyalty networks as the agents manipulating the electoral process. It predicts (i) that the relationship between violence and fraud follows an inverted U-shape and (ii) that(More)
Elections in developing countries commonly fail to deliver accountability because of manipulation, often involving collusion between corrupt election officials and political candidates. We report the results of an experimental evaluation of Photo Quick Count—a monitoring technology designed to detect the illegal sale of votes by corrupt election officials(More)
Does improved communication as provided by modern cell phone technology affect the production of violence during insurgencies? Theoretical predictions are ambiguous, introducing cell phones can enhance insurgent communications but can also make it easier for the population to share information with counterinsurgents and creates passive signals intelligence(More)
Despite substantial interest in the potential for mobile money to positively impact the lives of the poor, little empirical evidence exists to substantiate these claims. In this paper, we present the results of a field experiment in Afghanistan that was designed to increase adoption of mobile money, and determine if such adoption led to measurable changes(More)

We consider a game between a principal, an agent, and a monitor in which the principal would like to rely on messages by the monitor to target intervention against a misbehaving agent. The difficulty is that the agent can credibly threaten to retaliate against likely whistleblowers in the event of an intervention. In this setting intervention policies that(More)
We use structural estimates of time preferences to customize incentives for a sample of polio vaccinators during a series of door-to-door immunization drives in Pakistan. Our investigation proceeds in three stages. First, we measure time preferences using intertem-poral allocations of vaccinations. Second, we derive the mapping between these structural(More)
