Housing Adjustment Costs: Their Impact on Mobility and Housing Demand Elasticities

The role of housing adjustment costs in influencing mobility decisions, and the relationship between these and housing demands is not well understood. Here we try to examine how changes in adjustment costs as well as in such demand factors as income, influence the decision of households to adjust their housing consumption through moving. Empirically, we use a sample of recently moving homeowners from the PSID and provide evidence indicating adjustment costs are more important than other demand factors in influencing mobility decisions. We also argue that sample selection may bias estimates of housing demand elasticities when the sample is restricted to recent movers because the influence of adjustment costs in the mobility decision are not accounted for. Testing for this using the Heckman two‐stage procedure, however, showed this was not a significant problem.
