The Housing Assistance Supply Experiment: Tensions in Design and Implementation.
A brief discussion of the design features that make the housing assistance supply experiment (HASE) unusual among social experiments, and of the implications of these features for implementation of the experiment and the analysis of its results. HASE is designed to test the effects of a full-scale housing allowance program on the housing market within which it operates. It is a long-term saturation experiment encompassing all eligibles in two metropolitan housing markets. All participants receive benefits on the same terms at both sites. Treatment is aimed at low-income renters and homeowners; the monitoring program is aimed primarily at landlords, market intermediaries, and nonparticipating households who may be affected by the actions of the program participants. HASE's five-year monitoring program is expected to provide a large, versatile social-science research file. Accumulated data from each site will be edited, formatted, stored in machine-readable form, audited, and made accessible to analysts with a wide variety of interests. 6 pp.
