This paper presents the first analysis of the life course outcomes through late midlife (around age 55) for the participants of the iconic Perry Preschool Project, an experimental high-quality preschool program for disadvantaged African-American children in the 1960s. We discuss the design of the experiment, compromises in and adjustments to the randomization protocol, and the extent of knowledge about departures from the initial random assignment. We account for these factors in developing… Expand

What counts and matters in early childhood: Narratives of interests and outcomes
Evidence of outcomes of the early years is highly dependent on what is considered as an outcome, the curriculum and relationships children experience, and the research designs and methods used toExpand
Understanding How Low Levels of Early Lead Exposure Affect Children’s Life Trajectories
TLDR
It is found that even a low exposure affects long-run outcomes, that boys are more affected, and that changes in noncognitive skills explain a sizeable share of the impact on crime and human capital. Expand
An investigation of the causal effect of educational expectations on school performance. Behavioral consequences, time-stable confounding, or reciprocal causality?
Abstract Educational expectations are core concepts in the sociology of education. In this study, we are interested in the potential behavioral consequences of expectations on school performance inExpand
Gender Differences in (Some) Formative Inputs to Child Development
While there is a large literature on gender differences in important childhood developmental inputs in developing countries, the evidence for developed countries is relatively limited. I investigateExpand

Inference with Imperfect Randomization: The Case of the Perry Preschool Program
TLDR
It is found that the HighScope Perry Preschool program finds statistically significant effects of the program on a number of different outcomes of interest, including outcomes related to criminal activity for males and females, even after accounting for the imperfectness of the randomization and the multiplicity of null hypotheses.

The Rate of Return to the High/Scope Perry Preschool Program
TLDR
Estimated annual social rates of return generally fall between 7-10 percent, with most estimates substantially lower than those previously reported in the literature, but returns are generally statistically significantly different from zero for both males and females and are above the historical return on equity.

This chapter presents econometric and statistical methods for analyzing randomized experiments, and considers, in detail, estimation and inference for heterogenous treatment effects in settings with (possibly many) covariates. Expand

Sampling‐Based versus Design‐Based Uncertainty in Regression Analysis
TLDR
This article derives standard errors that account for design-based uncertainty instead of, or in addition to, sampling- based uncertainty and shows that their standard errors in general are smaller than the usual infinite-population sampling-based standard errors and provide conditions under which they coincide.

Randomization inference for treatment effects on a binary outcome.
TLDR
Simulations are presented comparing the two randomization-based confidence sets with the asymptotic interval as well as the standard Wald confidence interval and a commonly used exact interval for the difference in binomial proportions. Expand
