Experimental Social Programs and Analytic Methods: An Evaluation of the U.S. Income Maintenance Projects examines the statistical and econometric research on work disincentive effects reported by a series of social experiments that explore the economic and social consequences of a guaranteed income program. This book provides a comparative description of the several experimental designs and labor supply results, including a general discussion of methodological issues common to the social experiments. The Conlisk-Watts model for sample assignment and labor supply findings from both an econometric and statistical perspective are also elaborated. This text likewise presents an updated survey of the work response findings from the American negative income tax experiments. This publication is intended for professionals and students in econometrics, labor economics, statistics, and quantitative research, but is also valuable to policy analysts and others concerned with social welfare reform and public administration.
