We evaluate a program in Pakistan that equips government health inspectors with a smartphone app which channels data on rural clinics to senior policy makers. The system led to rural clinics being inspected 104% more often after 6 months, but only 43.8% more often after a year, with the latter...

Public sector absenteeism undermines service delivery in many developing countries. We report results from an at-scale randomized control evaluation in Punjab, Pakistan of a reform designed to address this problem. The reform affects healthcare for 100 million citizens across 297 political...

This paper provides evidence that the personalities of policymakers matter for policy. Three results support the relevance of personalities for policy. First, doctors with higher Big Five and Perry Public Sector Motivation scores attend work more and falsify inspection reports less. Second,...

Identifying the role of intrinsic, ideological motivation in political behavior is confounded by agents' consequential aims and social concerns. We present results from two experiments that implement a methodology isolating Pakistani men's intrinsic motives for expressing anti-American ideology,...

Most aid spending by governments seeking to rebuild social and political order is based on an opportunity-cost theory of distracting potential recruits. The logic is that gainfully employed young men are less likely to participate in political violence, implying a positive correlation between...

We report on an experiment examining why default options impact behavior. By randomly assigning employees to different varieties of a salary-linked savings account, we find that default enrollment increases participation by 40 percentage points--an effect equivalent to providing a 50% matching...

We use structural estimates of time preferences to customize incentives for polio vaccinators in Lahore, Pakistan. We measure time preferences using intertemporal allocations of effort, and derive the mapping between these structural estimates and individually optimized incentives. We evaluate...

When households increase their deposits in formal bank savings accounts, what is the source of the money? We combine high-frequency surveys with an experiment in which a Sri Lankan bank used mobile Point-of-Service (POS) terminals to collect deposits directly from households each week. In this...

Religious adherence has been hard to study in part because it is hard to measure. We develop a new measure of religious adherence, which is granular in both time and space, using anonymized mobile phone transaction records. After validating the measure with traditional data, we show how it can...

We review an emerging experimental literature studying institutional change. Institutions are a key determinant of economic growth, but the "critical junctures" in which institutions can change are not precisely defined. For example, such junctures are often identified ex post, raising...
