Participatory development is designed to mitigate problems of political bias in pre-existing local government but also interacts with it in complex ways. Using a five-year randomized controlled study in 97 clusters of villages (194 villages) in Ghana, we analyze the effects of a major participatory development program on participation in, leadership of and investment by pre-existing political institutions, and on households’ overall socioeconomic well-being. Applying theoretical insights on political participation and redistributive politics, we consider the possibility of both cross-institutional mobilization and displacement, and heterogeneous effects by partisanship. We find the government and its political supporters acted with high expectations for the participatory approach: treatment led to increased participation in local governance and reallocation of resources. But the results did not meet expectations, resulting in a worsening of socioeconomic wellbeing in treatment versus control villages for government supporters. This demonstrates international aid’s complex distributional consequences.
Innovations for Poverty Action (IPA) invita a organizaciones y asociaciones civiles que trabajen con individuos en situación de riesgo expuestos a la violencia a participar en la convocatoria para participar en el proyecto “Construyendo Policías Eficaces, Resilientes y Confiables en México”.
El proyecto “Construyendo Policías Eficaces, Resilientes y Confiables en México” de la Universidad de Yale liderado por el Dr. Rodrigo Canales, tiene por objetivo diseñar y evaluar cómo las fuerzas policiales pueden enfrentar el reto de reducir la violencia, aumentar la legitimidad institucional y confianza en las instituciones, y fortalecer el estado de derecho.
En el marco del proyecto, se realizará una intervención comunitaria en conjunto con la Secretaría de Seguridad Ciudadana de la Ciudad de México. Esta intervención busca atender dinámicas de violencia grupal en territorios específicos para cambiar el comportamiento de individuos en situación de riesgo de ejercer violencia o ser víctima. Una parte fundamental de la estrategia se basa en el trabajo comunitario con las personas previamente identificadas por IPA como personas que se encuentran en mayor riesgo de cometer un acto de violencia o ser víctima.
La intervención se realizará de noviembre de 2019 a mayo de 2020 (con posibilidad de extensión) en aproximadamente 47 colonias en una zona vulnerable al poniente de la Ciudad de México y el número de individuos a intervenir oscila entre las 30 y 40 personas.
Las fuerzas policiales urbanas tienden a enfocar sus esfuerzos en las áreas con tasas de crimen más altas. Sin embargo, incrementar la presencia estatal en los sitios más inseguros puede simplemente desplazar el crimen a otras áreas, dejando las tasas de crimen agregadas iguales a como estaban en un principio. En Bogotá, Colombia, un grupo de investigadores, en alianza con la Alcaldía de la ciudad, decidieron medir el impacto de tres estrategias sobre la reducción del crimen y su desplazamiento: focalizar la vigilancia policial, hacer mejoras al espacio público y una combinación de ambas estrategias. La evaluación encontró que estas estrategias reducen el crimen en las calles focalizadas en el estudio, pero solo cuando son implementadas al mismo tiempo. Mientras la mayoría de los crímenes, particularmente los delitos contra la propiedad parecen desplazarse a las calles aledañas. Hay evidencia que sugiere que los crímenes violentos, especialmente los homicidios y el abuso sexual, disminuyen en toda la ciudad como resultado de la intervención.
Lessons from randomized evaluations on managing and preventing crime, violence, and conflict.
What are the most promising strategies for reducing crime, violence, and conflict? The past decade has seen a dramatic expansion in the experimental literature designed to help answer this question. Moving beyond evaluations of individual programs, these studies seek to advance our understanding of what drives individuals and groups towards violence and conflict and the levers at our disposal for their reduction.
This evidence review, prepared by staff at the Abdul Latif Jameel Poverty Action Lab (J-PAL) and Innovations for Poverty Action (IPA) for the Department for International Development (DFID), offers a broad review of the expansion of this literature and seeks to capture some of the emerging insights from across these studies. The review has been prepared as part of J-PAL and IPA’s Governance, Crime and Conflict Initiative (GCCI), a £12-million investment by DFID launched in 2017 to produce new research on effective policies to promote peace and good governance, reduce crime, and support individuals and communities recovering from conflict.
We reviewed the existing experimental and rigorous quasi-experimental literature for studies that help to answer six questions identified in conversation with DFID staff1:
- What does and does not work in policing, including community policing?
- What does and does not work in terms of justice provision, including criminal justice and corrections/prisons?
- What do RCTs tell us about how to reduce the violent behavior of individuals in high-crime or conflict settings?
- What do RCTs tell us about how violent organizations/groups make strategic choices between violent and non-violent action?
- What do RCTs tell us about what works in peacebuilding, reconciliation and community-based/alternative dispute resolution?
- Does RCT evidence demonstrate that including women in interventions increases stability, conflict resolution, dispute resolution or violence reduction outcomes?

Innovations for Poverty Action (IPA) is a research and policy non-profit that discovers and promotes effective solutions to global poverty problems. IPA brings together researchers and decision-makers to design, rigorously evaluate, and refine these solutions and their applications, ensuring that the evidence created is used to improve the lives of the world’s poor. Since our founding in 2002, IPA has worked with over 575 leading academics to conduct over 650 evaluations in 51 countries. Future growth will be concentrated in focus countries, such as Myanmar, where we have local and international staff, established relationships with government, NGOs, and the private sector, and deep knowledge of local issues.
Over the past two decades, sports programs have proliferated as a mode of engaging youth in development projects. Thousands of organizations, millions of participants, and hundreds of millions of dollars are invested in sports-based development programs each year. The underlying belief that sports promote socioemotional skills, improve psychological well-being, and foster traits that boost labor force productivity has provided motivation to expand funding and offerings of sport for development (SFD) programs. We partnered with an international NGO to randomly assign 1200 young adults to a sports and life skills development program. While we do not see evidence of improved psychosocial outcomes or resilience, we do find evidence that the program caused a 0.12 standard deviation increase in labor force participation. Secondary analysis suggests that the effects are strongest among those likely to be most disadvantaged in the labor market.
Los grupos armados urbanos—especialmente las bandas criminales—son un obstáculo para el desarrollo económico y la consolidación de entornos pacíficos en muchas ciudades del mundo. Frecuentemente, estos grupos actúan como cuerpos estatales, ejecutando acciones típicamente gubernamentales como la resolución de disputas, la provisión de justicia y seguridad, la prevención del crimen, la regulación de mercados y la recolección de impuestos. En Medellín, Colombia, en alianza con la alcaldía de la ciudad, un grupo de investigadores diseñó una intervención para aumentar la participación del gobierno municipal en la provisión de servicios públicos y evaluar el impacto de ésta sobre la legitimidad del Estado y las bandas criminales.
We evaluate the impact of a large-scale information and mobilization intervention designed to improve health service delivery in rural Uganda by increasing citizens’ ability to monitor and apply bottom-up pressure on underperforming health workers. Modeled closely on the landmark “Power to the People” study (Björkman and Svensson, 2009), the intervention was undertaken in 376 health centers in 16 districts and involved a three-wave panel of more than 14,000 households. We find that while the intervention had a modest positive impact on treatment quality and patient satisfaction, it had no effect on utilization rates or health outcomes (including child mortality). We also find no evidence that the channel through which the intervention affected treatment quality was citizen monitoring. The results hold in a wide set of pre-specified subgroups and also when, via a factorial design, we break down the complex intervention into its two most important components. Our findings cast doubt on the power of information to foster community monitoring or to generate improvements in health outcomes, at least in the short term.
We embed a field experiment in a nationwide recruitment drive for nurses in Zambia to test whether career benefits attract talent at the expense of prosocial motivation. We randomize the offer of career benefits at the recruitment stage. In line with common wisdom, treatment attracts less prosocial applicants. However, the trade-off only exists at low levels of talent; the marginal applicants in treatment are more talented and equally pro-social. These are hired, and they perform better at every step of the chain: they deliver more services, promote institutional childbirth, and reduce child malnutrition by 25% in the communities they serve.
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.
In 2016 the city of Bogotá doubled police patrols and intensified city services on high-crime streets. They did so based on a policy and criminological consensus that such place-based programs not only decrease crime, but also have positive spillovers to nearby streets. To test this, we worked with Bogotá to experiment on an unprecedented scale. They randomly assigned 1,919 streets to either 8 months of doubled police patrols, greater municipal services, both, or neither. Such scale brings econometric challenges. Spatial spillovers in dense networks introduce bias and complicate variance estimation through “fuzzy clustering.” But a design-based approach and randomization inference produce valid hypothesis tests in such settings. In contrast to the consensus, we find intensifying state presence in Bogotá had modest but imprecise direct effects and that such crime displaced nearby, especially property crimes. Confidence intervals suggest we can rule out total reductions in crime of more than 2–3% from the two policies. More promising, however, is suggestive evidence that more state presence led to an 5% fall in homicides and rape citywide. One interpretation is that state presence may more easily deter crimes of passion than calculation, and place-based interventions could be targeted against these incredibly costly and violent crimes.
In Mexico, we have continued our global tradition of rigorous, applicable research by building foundational research capacity and conducting evaluations in areas of pressing national concern. Examples of our work detailed in this brief promising insights into everyday issues that affect the lives of people in Mexico.
Designers and funders of payments for ecosystem services (PES) programs have long worried that payments flow to landholders who would have conserved forests even without the program, undermining the environmental benefits (“additionality”) and cost-effectiveness of PES. If landholders self-select into PES programs based on how much conservation they were going to undertake anyway, then those who were planning to conserve should always enroll. This paper discusses the less-appreciated fact that enrollment is often based on other factors too. The hassle of signing up or financial costs of enrollment (e.g., purchasing seedlings) can affect who participates in a PES program. These enrollment costs reduce overall take-up, and, importantly, they can also influence the composition of landholders who select into the program—and thereby the program’s environmental benefits per enrollee. Enrollment costs can increase a program’s benefits per enrollee if they are systematically higher for (and thus deter enrollment by) landholders who would have conserved anyway. Alternatively, enrollment costs can dampen per-enrollee benefits if their correlation with status-quo conservation is in the opposite direction. We illustrate these points with evidence from two studies of randomized trials of PES programs aimed at increasing forest cover in Uganda and Malawi. We also discuss how in other sectors, such as social welfare, policy designers have purposefully adjusted the costs of program enrollment to influence the composition of participants and improve cost-effectiveness. We propose that these ideas for targeting could be incorporated into the design of PES programs.
In 2008, Uganda granted hundreds of small groups $400/person to help members start individual skilled trades. Four years on, an experimental evaluation found grants raised earnings by 38% (Blattman, Fiala, Martinez 2014). We return after 9 years to find these start-up grants acted more as a kick-start than a lift out of poverty. Grantees' investment leveled off; controls eventually increased their incomes through business and casual labor; and so both groups converged in employment, earnings, and consumption. Grants had lasting impacts on assets, skilled work, and possibly child health, but had little effect on mortality, fertility, health or education.
Governments are tasked with delivering basic services such as education, security, and infrastructure, but access to and quality of these services is often undermined by poor oversight, corruption, and lack of community participation.
While countless programs aim to address these issues, their effectiveness is often not clear. IPA’s governance research investigates ways to increase the performance of the government institutions that serve as the foundation for development. Our research teams have shed light on pressing questions including how to reduce vote-selling, how to increase the demand for government accountability, how technology can be used to reduce corruption, and how information can improve voting behavior, but many unanswered questions remain.
