Voter mobilization campaigns face trade-offs in young democracies. In a large-scale experiment implemented in 2013 with the Kenyan Electoral Commission (IEBC), text messages intended to mobilize voters boosted participation but also decreased trust in electoral institutions after the election, a decrease that was stronger in areas that experienced election-related violence, and for individuals on the losing side of the election. The mobilization backfired because the IEBC promised an electronic voting system that failed, resulting in manual voting and tallying delays. Using a simple model, we show signaling high institutional capacity via a mobilization campaign can negatively affect beliefs about the fairness of the election.
Background: Helminth and protozoan infections affect >1 billion children globally. Improved water, sanitation, handwashing, and nutrition could be more sustainable control strategies for parasite infections than mass drug administration (MDA), while providing other quality of life benefits. Methods and Findings: We enrolled geographic clusters of pregnant women into a cluster-randomized controlled trial that tested six interventions: disinfecting drinking water(W), improved sanitation(S), handwashing with soap(H), combined WSH, improved nutrition(N), and combined WSHN. We assessed intervention effects on parasite infections by measuring Ascaris lumbricoides, Trichuris trichiura, hookworm, and Giardia duodenalis among individual children born to enrolled mothers and their older siblings (ClinicalTrials.gov NCT01704105). We collected stool specimens from 9077 total children in 622 clusters, including 2346 children in control, 1117 in water, 1160 in sanitation, 1141 in handwashing, 1064 in WSH, 1072 in nutrition, and 1177 in WSHN. In the control group, 23% of children were infected with Ascaris lumbricoides, 1% with Trichuris trichuria, 2% with hookworm and 39% with Giardia duodenalis. After two years of intervention exposure, Ascaris infection prevalence was 18% lower in the water treatment arm (95% confidence interval (CI) 0%, 33%), 22% lower in the WSH arm (CI 4%, 37%), and 22% lower in the WSHN arm (CI 4%, 36%) compared to control. Individual sanitation, handwashing, and nutrition did not significantly reduce Ascaris infection on their own, and integrating nutrition with WSH did not provide additional benefit. Trichuris and hookworm were rarely detected, resulting in imprecise effect estimates. No intervention reduced Giardia. Reanalysis of stool samples by quantitative polymerase chain reaction (qPCR) confirmed the reductions in Ascaris infections measured by microscopy in the WSH and WSHN groups. Lab technicians and data analysts were blinded to treatment assignment, but participants and sample collectors were not blinded. The trial was funded by the Bill & Melinda Gates Foundation and USAID. Conclusions: Our results suggest integration of improved water quality, sanitation, and handwashing could contribute to sustainable control strategies for Ascaris infections, particularly in similar settings with recent or ongoing deworming programs. Water treatment alone was similarly effective to integrated WSH, providing new evidence that drinking water should be given increased attention as a transmission pathway for Ascaris.

IPA’s Peace & Recovery program is designed to support field experiments and related research in several broad areas:
- Reducing violence and promoting peace
- Reducing “fragility” (i.e. fostering state capability and institutions of decision-making)
- Preventing, coping with, and recovering from crises (focusing on conflict, but also including non-conflict humanitarian crises)
This document highlights the aims, core themes, research questions, and focus countries for P&R calls for proposals which will be taking place twice a year during 2018 and 2019.
African agricultural markets are characterized by low revenues for farmers and high food prices for consumers. Many have worried that this wedge is partially driven by imperfect competition among intermediaries. This paper provides experimental evidence from Kenya on intermediary market structure. Experimentally elicited parameters governing cost pass-through and demand curvature are used to calibrate a structural model of market competition. Estimates reveal a high degree of intermediary market power, with large implied losses to consumer welfare and market e ciency. Exogenously induced firm entry has negligible effects on prices and competitiveness parameters, implying that marginal entry does not meaningfully enhance competition.
Although abortion is now legal in Kenya under expanded circumstances, access is limited and many providers and individuals still believe it is illegal. This study aimed to characterise Kenyan women’s perceptions and experiences with abortion and post-abortion care (PAC) services in Nairobi regarding barriers to care, beliefs about abortion, and perceived stigma. We conducted 15 semi-structured in-depth interviews with Kenyan women aged 18–24 years who recently received abortion and PAC services at four Marie Stopes Kenya clinic sites in Nairobi. The most significant psychosocial barrier respondents faced in promptly seeking abortion and PAC was perceived stigma. In response to stigma, participants developed a sense of agency and self-reliance, which allowed them to prioritise their own healthcare needs over the concerns of others. To adequately address perceived stigma as a barrier to abortion- and PAC-seeking, significant cultural norm shifting is required.
Large and regular seasonal price fluctuations in local grain markets appear to offer African farmers substantial inter-temporal arbitrage opportunities, but these opportunities remain largely unexploited: small-scale farmers are commonly observed to "sell low and buy high" rather than the reverse. In a field experiment in Kenya, we show that credit market imperfections limit farmers' abilities to move grain inter-temporally. Providing timely access to credit allows farmers to buy at lower prices and sell at higher prices, increasing farm revenues and generating a return on investment of 28%. To understand general equilibrium effects of these changes in behavior, we vary the density of loan offers across locations. We document significant effects of the credit intervention on seasonal price fluctuations in local grain markets, and show that these GE effects shape individual level profitability estimates. In contrast to existing experimental work, the results indicate a setting in which microcredit can improve firm profitability, and suggest that GE effects can substantially shape microcredit's effectiveness. In particular, failure to consider these GE effects could lead to underestimates of the social welfare benefits of microcredit interventions.
