RT Journal Article SR Electronic T1 Supportive Housing and Neighborhood Property Value Externalities JF Land Economics JO Land Econ FD University of Wisconsin Press SP 33 OP 54 DO 10.2307/3147143 VO 80 IS 1 A1 Galster, George A1 Tatian, Peter A1 Pettit, Kathryn YR 2004 UL http://le.uwpress.org/content/80/1/33.abstract AB We analyzed impacts on single-family home prices of eleven, small-scale supportive housing facilities announced in Denver during 1989–1995.Using a difference in differences econometric specification, we found that these facilities produced a positive impact on house prices within 1,001 to 2,000 feet. We attributed this effect to countervailing externalities (building rehabilitation vs. resident behaviors) that vary in their spatial extent. Supportive housing facilities were systematically sited in neighborhoods with declining relative prices compared to elsewhere in the census tract. This location bias led a conventional econometric specification to erroneously estimate a negative property value impact from supportive housing. (JEL R11, R31)
