November 2012Understanding the Mechanisms through Which an Influential Early Childhood Program Boosted Adult Outcomes
with James J. Heckman, Rodrigo Pinto: w18581
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 traits from an experimental evaluation of the influential Perry Preschool program to analyze the channels through which the program boosted both male and female participant outcomes. Experimentally induced changes in personality traits explain a sizable portion of adult treatment effects.

July 2010Analyzing Social Experiments as Implemented: A Reexamination of the Evidence From the HighScope Perry Preschool Program
with James J. Heckman, Seong Hyeok Moon, Rodrigo Pinto, Adam Yavitz: w16238
Social experiments are powerful sources of information about the effectiveness of interventions. In practice, initial randomization plans are almost always compromised. Multiple hypotheses are frequently tested. "Significant" effects are often reported with p-values that do not account for preliminary screening from a large candidate pool of possible effects. This paper develops tools for analyzing data from experiments as they are actually implemented. We apply these tools to analyze the influential HighScope Perry Preschool Program. The Perry program was a social experiment that provided preschool education and home visits to disadvantaged children during their preschool years. It was evaluated by the method of random assignment. Both treatments and controls have been followed from age ...

A New Cost-Benefit and Rate of Return Analysis for the Perry Preschool Program: A Summary
with James J. Heckman, Seong Hyeok Moon, Rodrigo Pinto, Adam Yavitz: w16180
This paper summarizes our recent work on the rate of return and cost-benefit ratio of an influential early childhood program.

November 2009The Rate of Return to the High/Scope Perry Preschool Program
with James J. Heckman, Seong Hyeok Moon, Rodrigo Pinto, Adam Yavitz: w15471
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 preschool education programs. Previous studies of the rate of return to this program ignore the compromises that occurred in the randomization protocol. They do not report standard errors. The rates of return estimated in this paper account for these factors. We conduct an extensive analysis of sensitivity to alternative plausible assumptions. Estimated social rates of return generally fall between 7-10 percent, with most estimates substantially lower than those previously reported in the literature...
