In 2015-2017 Twaweza East Africa implemented KiuFunza II, a randomized performance pay trial in the early grades of public primary schools in Tanzania. This trial is part of an experimental program to improve learning introduced by Twaweza in collaboration with J-PAL/IPA. KiuFunza implemented two different teacher performance pay systems. The first system is called Stadi (levels) and rewards teachers based on the number of students that reach specific proficiency levels. The second is called Mashindano (gains) and rewards teachers based on their students’ test score ranking relative to children with the same starting level.  The performance pay learning impact was studied in a nationally representative sample of 180 schools (60 schools randomly selected into each of the two incentive pay programs, and 60 control schools). The evaluation finds that both teacher performance pay systems improved student test scores. The simpler “levels” system was at least as effective in raising student...

To test the causal impact of religiosity, we conducted a randomized evaluation of an evangelical Protestant Christian values and theology education program that consisted of 15 weekly half-hour sessions. We analyze outcomes for 6,276 ultra-poor Filipino households six months after the program ended. We find significant increases in religiosity and income, no significant changes in total labor supply, assets, consumption, food security, or life satisfaction, and a significant decrease in perceived relative economic status. Exploratory analysis suggests the program may have improved hygienic practices and increased household discord, and that the income treatment effect may operate through increasing grit.

Helping the ultra-poor develop sustainable livelihoods is a global priority, but policymakers, practitioners, and funders are faced with competing ideas about the best way to reduce extreme poverty. Innovations for Poverty Action conducted a randomized evaluation to test the impacts of diverse components and variants of the Village Enterprise microenterprise program, an integrated poverty alleviation intervention that provides poor households with a combination of cash transfers, mentorship, business training, and support with the formation of savings groups, over a one-year period. Key Findings* Village Enterprise’s microenterprise development program led to increased consumption, assets, and income, as well as improvements in nutrition and subjective well-being. Cost-effectiveness appears high: researchers estimate a full cost recovery within three to four years. A cost-equivalent cash transfer appeared to have less promising medium-term impacts on poverty reduction and subjective w...

Background Poor nutrition and infectious diseases can prevent children from reaching their developmental potential. We aimed to assess the effects of improvements in water, sanitation, handwashing, and nutrition on early child development in rural Kenya. Methods In this cluster-randomised controlled trial, we enrolled pregnant women in their second or third trimester from three counties (Kakamega, Bungoma, and Vihiga) in Kenya’s western region, with an average of 12 households per cluster. Groups of nine geographically adjacent clusters were block-randomised, using a random number generator, into the six intervention groups (including monthly visits to promote target behaviours), a passive control group (no visits), or a double-sized active control group (monthly household visits to measure child mid-upper arm circumference). The six intervention groups were: chlorinated drinking water; improved sanitation; handwashing with soap; combined water, sanitation, and handwashing; improved nu...

Social networks are an important mechanism for diffusing information when institutions are missing, but there may be distributional consequences from targeting only central nodes in a network. After implementing a social network census, one of three village-level treatments determined which treated nodes in the village received information about composting: random assignment, nodes with the highest degree, or nodes with high betweenness. We then look at how information diffuses through the network. We find information diffusion declines with social distance, suggesting frictions in the diffusion of information. Aggregate knowledge about the technology did not differ across targeting strategies, but targeting nodes using betweenness measures in village-level networks excludes less-connected nodes from new information. Women farmers are less likely to receive information when betweenness centrality is used in targeting, suggesting there are important gender differences, not only in the r...

Background Poor nutrition and exposure to faecal contamination are associated with diarrhoea and growth faltering, both of which have long-term consequences for child health. We aimed to assess whether water, sanitation, handwashing, and nutrition interventions reduced diarrhoea or growth faltering. Methods The WASH Benefits cluster-randomised trial enrolled pregnant women from villages in rural Kenya and evaluated outcomes at 1 year and 2 years of follow-up. Geographically-adjacent clusters were block-randomised to active control (household visits to measure mid-upper-arm circumference), passive control (data collection only), or compound-level interventions including household visits to promote target behaviours: drinking chlorinated water (water); safe sanitation consisting of disposing faeces in an improved latrine (sanitation); handwashing with soap (handwashing); combined water, sanitation, and handwashing; counselling on appropriate maternal, infant, and young child feeding plus...

A multi-faceted program comprising a grant of productive assets, training, coaching, and savings has been found to build sustainable income for those in extreme poverty. We focus on two important questions: whether a mere grant of productive assets would generate similar impacts (it does not), and whether access to a savings account and a deposit collection service would generate similar impacts (it does not).

A debt trap occurs when someone takes on a high-interest rate loan and is barely able to pay back the interest, and thus perpetually finds themselves in debt (often by re-financing). Studying such practices is important for understanding financial decision-making of households in dire circumstances, and also for setting appropriate consumer protection policies. We conduct a simple experiment in three sites in which we paid off high-interest moneylender debt of individuals. Most borrowers returned to debt within six weeks. One to two years after intervention, treatment individuals were borrowing at the same rate as control households.

We report results of a randomized control trial in which parents of primary school leavers were encouraged to open a convenient bank account operated over a mobile money platform. A lock savings account (LSA) was randomly promoted to half the treatment group. Treatment boosted account take-up by 25 percentage points. Intent-to-treat estimates show that being offered either account increased savings on the mobile phone. Total financial savings increased by 3-4 times, suggesting access to the mobile bank account crowded in other forms of savings. High school enrollment was 5-6 percentage points higher – representing a one third increase for compliers.

Improving learning outcomes is a key policy priority in Ghana. To ensure that well-intentioned policy goals translate into improved learning outcomes, decision-makers are eager to: (1) evaluate the success of education programs through rigorous research; and (2) build sector-wide frameworks of accountability through improved monitoring and feedback mechanisms. Both forms of evidence are necessary for a strong education system. Evidence Day, a part of the Ghana Ministry of Education's Education Week, will bring together policymakers, researchers, and practitioners to: a) share rigorous evidence about improving accountability and learning outcomes in education, in Ghana and internationally; b) identify ways in which evidence from evaluations can be used for better decision- making; and c) share monitoring and evaluation tools that can inform a framework of accountability for Ghana’s education sector.

Preventing violence against women (VAW) requires witnesses to come forward, yet willingness to report is often undermined by social sanctions against those suspected of fabricating allegations. Our theory of the micro-politics of information disclosure in interdependent communities elucidates the role of social norms in preventing VAW. We present experimental evidence from a media campaign attended by over 10,000 Ugandans in 112 rural villages that featured three short videos designed to encourage reporting of VAW in the household. Results indicate a substantial reduction in VAW over a 6-month period following the campaign. Investigation of mechanisms reveals that women in the treatment group became less likely to believe that they would be labeled a gossip if they were to report an incident of VAW, and their personal willingness to speak out increased substantially. We find no evidence of a deeper change in core values pertaining to VAW.

Gender gaps in participation and representation are common in new democracies, both at the elite level and at the grassroots. We investigate efforts to close the grassroots gender gap in rural Ghana, a patronage-based democracy in which a dense network of political party branches provides the main avenue for local participation. We report results from a randomized field experiment to address norms against women's participation and encourage women's participation ahead of Ghana's December 2016 elections. The treatment is a large community meeting presided over by the traditional chief, known locally as a durbar. We find null results. The treatment was hampered in part by its incomplete implementation, including by local political party leaders who may have feared an electorally-risky association with a controversial social message. The study emphasizes the importance of social norms in explaining gender gaps in grassroots politics in new democracies and contributes new evidence on the l...

Can democratic elections reduce rent extraction by public decision makers? Existing research suggests that reelection incentives can reduce the embezzlement of public funds. This paper examines three additional mechanisms through which democratic elections could have an impact on embezzlement, even in the absence of reelection incentives: (1) electoral selection effects, (2) social norms and norm enforcement, and (3) citizens’ trust in decision makers. Evidence from an experiment with 472 groups of citizens in rural Burkina Faso suggests that electoral selection favors benevolent candidates. Furthermore, elections increase citizens’ willingness to punish corrupt decision makers, even if their ability to do so remains unchanged. However, these beneficial effects of elections are offset by an unexpected adverse effect: elections cause citizens to trust decision makers more than they should be trusted. These findings have important implications for the role of information in electoral dem...

The Small and Medium Enterprise (SME) Program at IPA discovers and promotes effective solutions to the constraints faced by entrepreneurs and SMEs in developing countries. SMEs are the largest generators of employment in the developing world, creating nearly 60% of new jobs. They also generate a myriad of opportunities across sectors and geographic areas, and employ broad and diverse segments of the labor force. SMEs in developing countries, however, face constraints that are disproportionately large compared to those faced by larger firms and by SMEs in developed countries. Limited access to finance, low levels of human capital, and difficulty accessing markets stand out as some of the most challenging barriers to business growth.

Politicians shirk when their performance is obscure to constituents. We theorize that when politician performance information is disseminated early in the electoral term, politicians will subsequently improve their performance in anticipation of changes in citizens’ evaluative criteria and possible challenger entry in the next election. However, politicians may only respond in constituencies where opposition has previously mounted. We test these predictions in partnership with a Ugandan civil society organization in a multiyear field experiment conducted in 20 district governments between the 2011 and 2016 elections. While the organization published yearly job duty performance scorecards for all incumbents, it disseminated the scorecards to constituents for randomly selected politicians. These dissemination efforts induced politicians to improve performance across a range of measures, but only in competitive constituencies. Service delivery was unaffected. We conclude that, conditional...
