Hutchinson, T.2008-12-022008-12-022008Housing Policy Debate, 2008; 19(3):573-5821051-14822152-050Xhttp://hdl.handle.net/2440/48514Published online: 31 Mar 2010In his 2005 article “Valuing the Suburbs: Why Some ‘Improvements’ Lower Home Prices,” Robert E. Lang proposes an explanation of why improvements to a home may either add to or detract from its value. He suggests a dual housing market: “one for conventional low-density suburbs, and one for cities and denser suburbs” (8). The former values features implying a natural or less intense use, and the latter values features adding “intensity or utility to a property” (8). This article reinterprets Lang’s explanation as an example of interaction (something having a different effect under one condition than it does under another) arising via summation followed by a nonlinear function of the result. An alternative explanation in terms of the fit between characteristics of a home and its location is also noted.en© 2008 Metropolitan Institute at Virginia Tech.
