1. Disruptions to Early Childhood Preschool Services During a Pandemic: Evidence from India (with Manisha Shah

Accepted, Journal of Population Economics

Abstract: Much less is known about the impacts of the COVID-19 pandemic on the provision of early childhood preschool services relative to research on school closures. We conduct surveys with more than 5,000 early childhood service providers and leverage temporal and spatial variation in India's intensity of lockdowns to quantify disruptions to preschool services between areas with differently-strict lockdown measures under the world's largest early childhood development program. We document a 23 percentage point reduction in the provision of preschool services in red zone lockdown areas (strictest measures) relative to green zone lockdown areas (least strict measures). We find that pre-COVID measures of high worker locus of control and public service motivation offset the reduction in differential preschool service provision by 27-37 percent.

Abstract: Can governments leverage existing service-delivery platforms to scale early childhood development (ECD) interventions? We experimentally study a large-scale, low-cost home-visiting interventionproviding materials and counselingintegrated into Bangladesh's national nutrition program without extra financial incentives for service providers (SPs). We find SPs partially substitute away from nutritional to ECD counseling. Intent-to-treat estimates show positive impacts on child's cognition (0.17 SD), language (0.23 SD), and socio-emotional scores (0.12-0.14 SD). Wasting and underweight rates decline. Older siblings' primary school attendance increases as well. Improved maternal agency, complementary parental investments, and higher take-up of the pre-existing nutrition program are important mechanisms. We estimate a sizeable internal rate-of-return of 18.9%.

Abstract: Violence against women is a problem worldwide, with economic costs ranging from 1% to 4% of global gross domestic product. During the coronavirus disease 2019 lockdowns, the United Nations coined the term the Shadow Pandemic to describe the increase in global violence against women. Here, using variation in the intensity of government-mandated lockdowns in India, we show that domestic violence complaints increase significantly in districts with the strictest lockdown rules. We find similarly large increases in cybercrime complaints. However, rape and sexual assault complaints decrease in districts with the strictest lockdowns, consistent with decreased female mobility in public spaces, public transport and workplaces where they might be at greater risk for rape and sexual assault. Medium-term analysis shows that increases in domestic violence complaints persist 1 year later, while other complaints related to rape, sexual assault and cybercrimes return to pre-lockdown levels.

4. Narrowing the Gender Gap in Mobile Banking (with Jean N. Lee, Jonathan Morduch, and Abu S. ShonchoyJournal of Economic Behavior and Organization, 2022.

Abstract: Mobile banking and related digital financial technologies can make financial services cheaper and more widely accessible in low-income economies, but gender gaps persist. We present evidence from two connected eld experiments in Bangladesh designed to encourage the adoption and use of mobile banking by poor, illiterate households. The study focuses on migrants who live in Dhaka and send money back to their extended families. Despite large differences between female and male migrants in income and education, the first experiment shows that a training program led to similarly large, positive impacts on mobile banking use by female migrants (a 51 percentage point increase) and male migrants (46 percentage point increase), substantially narrowing the gender gap. However, the increases in adoption did not lead to similar patterns in usage: men increased digital remittances by 11 times as much as women. A second experiment tests whether introducing the technology in the context of family networks made an additional difference to gender gaps. The evidence suggests an 11 percentage point increase in adoption by women and just a 1 percentage point increase by men, although statistical power is low for this comparison and estimates are imprecise.

Abstract: Rapid urbanization is reshaping economies and intensifying spatial inequalities. In Bangladesh, we experimentally introduced mobile banking to very poor rural households and family members who had migrated to the city, testing whether mobile technology can reduce inequality by modernizing traditional ways to transfer money. One year later, for active mobile banking users, urban-to-rural remittances increased by 26% of the baseline mean. Rural consumption increased by 7.5% and extreme poverty fell. Rural households borrowed less, saved more, sent additional migrants, and consumed more in the lean season. Urban migrants experienced less poverty and saved more, but bore costs, reporting worse health.

Abstract: The initial spread of COVID-19 halted economic activity as countries around the world restricted the mobility of their citizens. As a result, many migrant workers returned home, spreading the virus across borders. We investigate the relationship between migrant movements and the spread of COVID-19 using district-day-level data from Bangladesh, India, and Pakistan (the 1st, 6th, and 7th largest sources of international migrant workers). We find that during the initial stage of the pandemic, a 1 SD increase in prior international out-migration relative to the district-wise average in India and Pakistan predicts a 48% increase in the number of cases per capita. In Bangladesh, however, the estimates are not statistically distinguishable from zero. Domestic out-migration predicts COVID-19 diffusion in India, but not in Bangladesh and Pakistan. In all three countries, the association of COVID-19 cases per capita and measures of international out-migration increases over time. The results show how migration data can be used to predict coronavirus hotspots. More broadly, the results are consistent with large cross-border negative externalities created by policies aimed at containing the spread of COVID-19 in migrant-receiving countries.

1. The Social Meaning of Mobile Money: Earmarking Reduces the Willingness to Spend in Migrant Households (with Jean N. Lee, Jonathan Morduch, and Abu S. Shonchoy

Revision Resubmitted, Journal of Economic Behavior and Organization

Abstract: Behavioral household finance shows that people are often more willing to spend when using less tangible forms of money like debit cards or digital payments than when spending in cash. We show that this "payment effect" cannot be generalized to mobile money. We surveyed families in rural Northwest Bangladesh, where mobile money is mainly received from relatives working in factories. The surveys were embedded within an experiment that allows us to control for the relationships between senders and receivers of mobile money. The finding suggests that the source of funds matters, and mobile money is earmarked for particular purposes and thus less fungible than cash. In contrast to the expectation of greater spending, the willingness to spend in the rural sample was lower by 24 to 31 percent. In urban areas, where the sample does not receive remittances on net, there are no payment effects associated with mobile money.

Abstract: Approximately 75% of children aged 2 to 4 worldwide are regularly subjected to violent discipline across the globe. We study the impact of a virtually-delivered intervention on positive parenting practices in Jamaica. We find the intervention improves caregiver knowledge (0.52 SD) and attitudes around violence (0.2 SD) and leads to meaningful changes in caregiver disciplining behaviors, with a 0.12 SD reduction in violence against children. Treatment children also experience fewer emotional problems (0.17 SD). When we return nine months later, we also find reductions in caregiver depression (0.12 SD), anxiety (0.16 SD), and parental stress (0.16 SD) for treatment caregivers. The virtual delivery has important scalable policy implications which could help decrease violence against children across the globe.

Abstract: Policy decisions often depend on evidence generated elsewhere. We take a decision theoretic approach to choosing where to experiment to optimize external validity. We frame external validity through a policy lens, taking a Bayesian approach and developing a prior specification for the joint distribution of site-level treatment effects using a microe- conometric structural model and allowing for other sources of heterogeneity. With data from South Asia, we show that, relative to basing policies on experiments in optimal sites, large efficiency losses result from instead using evidence from randomly-selected sites or, conversely, from sites with the largest expected treatment effects.

Abstract: This paper provides new evidence on the impact of financial access on human capital outcomes for children. Using a regression discontinuity design, we study a branch authorization policy by the Reserve Bank of India that encouraged banks to open branches in underbanked districts, where the population-to-branch ratio exceeded the national average. Bank presence, bank lending, and household borrowing increased. We find significant improvements in test scores: children in underbanked districts scored 0.16–0.22 SD higher on reading and math. We document three mechanisms underlying these results. First, the increase in credit led to a demand-side channel where parents spent more on their children's education and children spent more time on homework. Second, we document supply-side impacts in the form of improvements in the quantity and quality of schools and teachers. Third, we find support for a labor market channel. We show that financial access led to increases in non-agricultural business loans that caused shifts away from agricultural employment and towards employment in manufacturing, while self-employed individuals expanded their businesses. Our results have important implications for financial inclusion and education policies in developing countries.

5. Parental Investments and Early Childhood Development: Short and Long Run Evidence from India  

Finalist, Human Capital and Economic Opportunity Dissertation Prize 2019, University of Chicago

[Poster]  Additional Coverage: Choosing among children: Early childhood investments in India, Ideas For India.  

Abstract: The overall impacts of early childhood programs depend on the indirect impacts that arise due to intra-household reallocation of parental investments. Using historical administrative data from the rollout of the largest early childhood development program in the world, I find that adults exposed to the program when young showed significant improvements in various measures of health, education, and labor market outcomes. Parents reallocated their investments toward children exposed to an increase in program intensity, as evidenced by negative spillovers on siblings. Accounting for the negative spillovers on siblings reduces the internal rate of return of the program by 9%.
