“…Instead of student characteristics, some studies include population demographics for the neighborhood such as shares of African Americans (or whites) (Bayer et al, 2007;Clauretie and Neill, 2000;Kane et al, 2006), and levels of education (Black, 1999;Brasington and Haurin, 2006;Reback, 2005;Barrow and Rouse, 2004). Some studies include median or mean household income as a proxy for residential housing demand or as a neighborhood amenity (Bayer et al, 2007;Davidoff and Leigh, 2008;Hilber and Mayer, 2009;Kane et al, 2003). As earlier discussed in greater detail, we believe that income does influence housing demand and thus is unlikely to be exogenous in the bid-function envelope, and that it is unlikely to be a good proxy for actual measures of neighborhood characteristics.…”
