Overview of the Final Report of the Seattle-Denver Income Maintenance Experiment. Appendix: Table of Contents of Final Report
The interested reader is referred to the two-volume Final Report of the Seattle-Denver Income Maintenance Experiment (Washington, D.C.: U.S. Government Printing Office, 1983) for a complete discussion of the design, administration, and results of SIME/DIME. Below is the Table of Contents for that report.
1. These correspond to 95%, 120%, and 140% of the official poverty line for a family of four ($4,000 in 1971 dollars). The relationship of these levels to the poverty line was preserved throughout the experimental period by adjusting the dollar guarantee levels regularly according to increases in the Consumer Price Index, as in the poverty lin
Overview of the Final Report of the Seattle-Denver Income Maintenance Experiment. Counseling/Training
With respect to the counseling/training subsidy results, two major points deserve emphasis. Participation in both the counseling and training-education programs was strongly related to the amount of the subsidy. Both the 50 percent and 100 percent subsidy plans induced statistically significant increases in formal schooling (although not work-
The work responses to be expected from transfer programs of varying generosity are much more precisely know as a result of SIME/DIME than they were before. It is now possible, as a consequence of the SIME/DIME labor supply analysis, to predict with some confidence how much more or less people will work as a result of new policy initiatives and w
How can the SIME/DIME results be used as a guide to the possible effects on family structure of new public policy initiatives? The analyst themselves "caution the reader against uncritically extrapolating from these or any other summary measure of the effects of SIME/DIME on marital dissolution." (11) They stress as reasons for this statement
Overview of the Final Report of the Seattle-Denver Income Maintenance Experiment. Effects on Marital Stability (9)
Although, as mentioned earlier, the experiment was not explicitly designed to test effects on marital stability, much attention was paid to the issue in terms of both data collection and analysis. To the extent that the effects of the experiment on marital dissolution were expected to depend on the guarantee and the tax rate, and to the extent t
Overview of the Final Report of the Seattle-Denver Income Maintenance Experiment. Counseling/Training Subsidy Effects
A unique feature of SIME/DIME among the four NIT experiments was the testing of a labor market counseling and training subsidy program in addition to a negative income tax transfer program. The rationale for including these programs was to determine whether increased labor market information and increased education and training could offset the
Overview of the Final Report of the Seattle-Denver Income Maintenance Experiment. Cash Transfer Effects on Labor Supply
The labor supply results for husbands, wives, female family heads, and youth will be summarized in turn. For each group, the overall response to the SIME/DIME negative income tax plans taken together is described first. A discussion of differences in response among the different NIT plans follows.
The major SIME/DIME results are presented under three headings. First, the effects of the experiment on work effort or labor supply are presented. The primary focus is the effect of eligibility for a negative income tax plan, but the analysis sample used to obtain these findings includes all families enrolled in the experiments, including thos
The composition of the SIME/DIME sample was defined partly with reference to the likely population to be included in any national negative income tax program and partly to assure that important questions about the magnitude of the overall work effort response and about possible differential responses by different population groups could be satisfa
The primary data for analysis of behavioral responses to the experiment came from a series of face-to-face interviews administered three times a year, for the duration of the treatment period and at least one year beyond. These took about forty minutes each, were administered in the families' homes by specially trained interviewers, and were ide
