Since 1970 the United States government has spent over half a billion dollars on social experiments intended to assess the effect of potential tax policies, health insurance plans, housing subsidies, and other programs. Was it worth it? Was anything learned from these experiments that could not have been learned by other, and cheaper, means? Could the experiments have been better designed or analyzed? These are some of the questions addressed by the contributors to this volume, the result of a conference on social experimentation sponsored in 1981 by the National Bureau of Economic Research.

The first section of the book looks at four types of experiments and what each accomplished. Frank P. Stafford examines the negative income tax experiments, Dennis J. Aigner considers the experiments with electricity pricing based on time of use, Harvey S. Rosen evaluates housing allowance experiments, and Jeffrey E. Harris reports on health experiments. In the second section, addressing experimental design and analysis, Jerry A. Hausman and David A. Wise highlight the absence of random selection of participants in social experiments, Frederick Mosteller and Milton C. Weinstein look specifically at the design of medical experiments, and Ernst W. Stromsdorfer examines the effects of experiments on policy. Each chapter is followed by the commentary of one or more distinguished economists.

Many Americans seem convinced that government programs designed to help the poor have failed. Social Programs That Work shows that this is not true. Many programs have demonstrably improved the lives of people trapped at the bottom of the social and economic ladder. Social Programs That Work provides an in-depth look at some of the nation's best interventions over the past few decades, and considers their potential for national expansion. Examined here are programs designed to improve children's reading skills, curb juvenile delinquency and substance abuse, and move people off welfare into the workforce. Each contributor discusses the design and implementation of a particular program, and assesses how well particular goals were met. Among the critical issues addressed: Are good results permanent, or do they fade over time? Can they be replicated successfully under varied conditions? Are programs cost effective, and if so are the benefits seen immediately or only over the long term? How can public support be garnered for a large upfront investment whose returns may not be apparent for years? Some programs discussed in this volume were implemented only on a small, experimental scale, prompting discussion of their viability at the national level. An important concern for social policy is whether one-shot programs can lead to permanent results. Early interventions may be extremely effective at reducing future criminal behavior, as shown by the results of the High/Scope Perry preschool program. Evidence from the Life Skills Training Program suggests that a combination of initial intervention and occasional booster sessions can be an inexpensive and successful approach to reducing adolescent substance abuse. Social Programs That Work also acknowledges that simply placing welfare recipients in jobs isn't enough; they will also need long-term support to maintain those jobs. The successes and failures of social policy over the last thirty-five years have given us valuable feedback about the design of successful social policy. Social Programs That Work represents a landmark attempt to use social science criteria to identify and strengthen the programs most likely to make a real difference in addressing the nation's social ills.
