This report reviews the effectiveness of early childhood stimulation interventions in developing countries. The report aims to answer the questions: What works in terms of early stimulation for young children in developing countries? For whom and under what conditions do these programs work and...

This paper critically reviews what we know about the long-term effects of parental leave and early childhood education programs. We find only limited evidence that expansions of parental leave durations improved long-run educational or labor market outcomes of the children whose parents were...

What happens to children's long-run cognitive development when introducing universal high-quality childcare for 3-year olds mainly crowds out maternal care? To answer this question we exploit a natural experiment framework and employ a difference-in-difference approach. We find sizable...

A growing literature establishes that high quality early childhood interventions targeted toward disadvantaged children have substantial impacts on later life outcomes. Little is known about the mechanisms producing these impacts. This paper uses longitudinal data on cognitive and personality...

This chapter presents an integrated economic approach that organizes and interprets the evidence on child development. It also discusses the indicators of child well-being that are used in international comparisons. Recent evidence on child development is summarized, and policies to promote...

How much of the income-based gaps in cognitive ability and academic achievement could be closed by a two-year, center-based early childhood education intervention? Data from the Infant Health and Development Program (IHDP), which randomly assigned treatment to low birth weight children from both...

This paper reviews the recent literature on measuring and boosting cognitive and noncognitive skills. The literature establishes that achievement tests do not adequately capture character skills – personality traits, goals, motivations, and preferences that are valued in the labor market, in...

This paper estimates the rate of return to the High/Scope Perry Preschool Program, an early intervention program targeted toward disadvantaged African-American youth. Estimates of the rate of return to the Perry program are widely cited to support the claim of substantial economic benefits from...

We offer a new strategy to identify the distribution of treatment effects using data from the Infant Health and Development Program (IHDP), a relatively understudied early-childhood intervention for low birth-weight infants. We introduce a new policy parameter, QCD, which denotes quantiles of...

This paper forecasts the life-cycle treatment effects on health of a high-quality early childhood program. Our predictions combine microsimulation using non-experimental data with experimental data from a midlife long-term follow-up. The follow-up incorporated a full epidemiological exam. The...
