We provide experimental evidence that enabling access to universal early child care increases maternal labor supply and promotes gender equality among families with lower socioeconomic status (SES). Our intervention offers information and customized help with child care applications, leading to...

Objective: Heart failure (HF) is a prevalent condition affecting millions of individuals worldwide. Continuous monitoring and targeted behavioral interventions have been shown to improve health status and quality of life for HF patients. Digital therapeutics offer the possibility to make more...

Wang et al. (2024) report that Bangladeshi students randomly given access to lessons on a phone server saw significant learning gains during COVID- 19 school closures. We identify three sets of anomalies. First, this experiment shares participants with another experiment conducted simultaneously...

In this study, we examine whether a nudging intervention increases eyeglass use among primary and lower-secondary students in Vietnam through a randomized controlled trial. Students with refractive errors in 34 schools in one province were provided with free eyeglasses. Half of the schools were...

Despite substantial investment in skills training worldwide, evidence for the effectiveness of such interventions in sub-Saharan Africa is still relatively sparse. We contribute to this literature by implementing a multisite randomized controlled trial (RCT) of the Professionalization of...

This paper evaluates a program that seeks to improve the levels of social inclusion of families with children and adolescents receiving the National Minimum Income Scheme (IMV) and/or the Regional Inclusion Income (RISGA) in the seven largest municipalities in Galicia, Spain. The intervention...

Replacing combustion engine vehicles with battery electric vehicles (BEV) is essential to achieving climate objectives and advancing sustainable transportation, aligning with the United Nations Development Goals and the Paris Agreement. In this project, we identify three perception biases linked...

Balán et al. (2022) evaluate the impact of "local elites" involvement in local tax collection in a large city in the Democratic Republic of Congo. Using a randomized controlled trial to vary the identities of tax collectors, they find that local elites' involvement raises tax compliance and...

Using randomized control trials (RCTs) applied over time in different countries, we study whether the economic environment affects how agents learn from new information. We show that as inflation rose in advanced economies, both households and firms became more attentive and informed about...

How strong are peer effects on the beliefs and spending decisions of individuals? We use a randomized control study in which treated households are told about either average income or debt of individuals like them to assess how peer effects influence their beliefs and spending. The information...

This paper presents the results from a randomized controlled trial of Chapter One, an early elementary reading tutoring program that embeds part-time tutors into the classroom to provide short bursts of 1:1 instruction. Eligible kindergarten students were randomly assigned to receive...

Why are children with lower socioeconomic status (SES) substantially less likely to be enrolled in child care? We study whether barriers in the application process work against lower-SES children - the group known to benefit strongest from child care enrollment. In an RCT in Germany with highly...

This paper studies inference in randomized controlled trials with multiple treatments, where treatment status is determined according to a "matched tuples" design. If there are |D| possible treatments, then by a matched tuples design, we mean an experimental design where units are sampled i.i.d....

The use of observational methods remains common in program evaluation. How much should we trust these studies, which lack clear identifying variation? We propose adjusting confidence intervals to incorporate the uncertainty due to observational bias. Using data from 44 development RCTs with...

Replacing combustion engine vehicles with battery electric vehicles (BEV) is essential to achieving climate objectives and advancing sustainable transportation, aligning with the United Nations Development Goals and the Paris Agreement. In this project, we identify three perception biases linked...

Early childhood development is a global priority, yet questions remain about how best to support disadvantaged children in low- and middle- income countries. We study the impacts of high-quality, center-based early childhood education on low income children in Colombia through a randomized...

Using randomized control trials (RCT) applied over time in different countries, we study how the economic environment affects how agents learn from new information. We show that as inflation has risen in developed economies, both households and firms have become more attentive and informed about...

Using randomized control trials (RCTs) applied over time in different countries, we study how the economic environment affects how agents learn from new information. We show that as inflation has recently risen in advanced economies, both households and firms have become more attentive and...

The Covid-19 pandemic caused prolonged school closures worldwide. Children in resource- poor settings were particularly affected given their limited access to remedial distance learning opportunities through the internet, television, and radio. To address the poor access to formal education, we...

Poor debt-management skills lower financial security and wealth accumulation. Because optimal solutions to credit repayment problems depend on neither risk preferences nor beliefs, loan repayment is a prime application for robo-advising. Vulnerable households, though, tend to distrust new...

Do non-traditional digital trace data and traditional survey data yield similar estimates of the impact of a cash transfer program? In a randomized controlled trial of Togo's COVID-19 Novissi program, endline survey data indicate positive treatment effects on beneficiary food security, mental...

We conducted a randomized evaluation of a universal primary prevention intervention whose main goal was to increase the resilience of students from a large broad-access Hispanic Serving Institution and commuter urban college. In a 90-minute workshop, students were: introduced to the...

We present experimental evidence that enabling access to universal early child care for families with lower socioeconomic status (SES) increases maternal labor supply. Our intervention provides families with customized help for child care applications, resulting in a large increase in enrollment...

This paper evaluates the Jumpstart Program (JSP), a parenting intervention implemented by a school district in the Houston area to enhance school readiness among economically disadvantaged three-year-old children. Unlike many early childhood programs typically tested in controlled research...

Children spend most of their time at home in their early years, yet efforts to promote human capital at home in many low- and middle-income settings remain limited. We conduct a randomized controlled trial to evaluate an intervention which encourages parents and caregivers to foster human...

Why and when could basic income inhibit employment? We randomize 200 dollars of basic income per month for two years within a non-urban disadvantaged sample tracked using high-frequency administrative data. The amount provided is 21% of average all-source income. In the short term (0.5 years...

Low-cost private schools have increased educational access in low-income countries, but frequent school closures lead to costly disruptions in children's schooling. We provide experimental evidence from Pakistan that both school loans and educational products and services (EPS) are (a)...

Eligibility criteria for interventions can induce an Ashenfelter Dip, and subsequent mean-reversion may result in improvement over time even absent the intervention. We investigate these dynamics for a food-as-medicine program to treat diabetes, where eligibility required elevated hemoglobin A1c...

"Demonstrating the effectiveness of nonprofit social programs is a challenge. This has led to a rapid rise in nonprofit organizations' use of randomized controlled trials (RCTs), for evaluation. As a result, most nonprofit sector professionals today can tell you why nonprofits should do an RCT....

We enrich a standard debt overhang model with liquidity constraints to guide the design and interpretation of a collateralized debt modification experiment on a publicly traded lender's delinquent vehicle loans to minibus entrepreneurs. Liquidity constraints add another borrower incentive...
