Compensating for landlord nonresponse in the Housing Assistance Supply Experiment

Addresses the possibility that rental-property owners selected to be interviewed as part of the Housing Assistance Supply Experiment (HASE) might decline to cooperate on a scale or in a pattern that threatens the integrity of the proposed HASE analysis of supply response. The Note explores possible reasons for bias or massive nonresponse, and evaluates both their likelihood and their implications for the analysis of landlord expenditure data. It also proposes a method for reinforcing the data base should these contingencies arise, a method believed to be both flexible enough to cope with a wide range of contingencies and efficient in its exploitation of data that are obtained from cooperative landlords; the method entails using data reported by the tenants of nonresponding landlords to estimate the landlord expenditures required for the supply-response analysis.
