Early childhood interventions aim to promote skill acquisition and poverty reduction. While their short-term success is well established, research on longer-term effectiveness is scarce, particularly in LDCs. We present results of a randomized scalable intervention in India, that affected...

Despite significant economic growth, child development outcomes in India remain poor. Using a large-scale experiment in which randomly-selected mothers receive cash transfers for the first two years of their child's life, we examine the relationship between income and child development in the...

The promise of randomized controlled trials is that evidence gathered through the evaluation of a specific program helps us--possibly after several rounds of fine-tuning and multiple replications in different contexts--to inform policy. However, critics have pointed out that a potential...

We present experimental evidence on the impact of a personalized technology-aided after-school instruction program on learning outcomes. Our setting is middle-school grades in urban India, where a lottery provided winning students with a voucher to cover program costs. We find that lottery...

Motivated by the quantitative and qualitative analysis of these early attempts, we adapted the approach and designed large-scale experiments in the states of Haryana and Uttar Pradesh to test two new scale-up models. In Haryana, teachers received support from government resource persons trained...

In an experiment in non-formal schools in Indian slums, a reward scheme for attending a target number of school days increased average attendance when the scheme was in place, but had heterogeneous effects after it was removed. Among students with high baseline attendance, the incentive had no...

India started the implementation of a rural public works program in 2006, covering all districts of the country within three years. The program quarantees 100 days of employment per year at minimum wage to each rural household on demand, with the goal of reducing joblessness and poverty. We...

We revisit two clinical trials that randomized depressed adults in India (n=775) to a brief course of psychotherapy or a control condition. Four to five years later, the treatment group was 11 percentage points less likely to be depressed than the control group. The more effective intervention...

Routine childhood vaccinations are among the most cost-effective interventions. In recent years, the broader benefits of vaccines, which include improved cognitive and schooling outcomes, have also been established. This paper evaluates the long-term economic benefits of India's national program...
