This article introduces Nash bargaining into a search model to identify various channels through which vacancy affects selling price and liquidity in the resale market for houses. The model shows the various vacancy effects in the form of greater seller holding cost, lower seller bargaining power and unobserved negative attributes or stigma. We use a 20-year data series on house transactions to test for these effects in a simultaneous model of price and liquidity, using the long data series to allow for variation across market phases. The robust vacancy effects on price and liquidity across all market phases primarily reflect greater seller holding cost and diminished bargaining power. Repeatedly, vacant houses also exhibit significant stigma effects in the rising market but not in stable or declining market phases. At the same time, vacant houses enjoy stronger shopping externality effects from surrounding houses for sale than do their occupied counterparts.
