“…First, it builds upon the literature on the efficiency of housing markets and the predictability of real estate returns (see for example Case and Shiller, 1989, 1990, Gillen et al, 2001, Gu, 2002, Cappozza et al 2004, Miller and Sklarz, 1986, among others) because this paper incorporates a rational expectation model of home value appreciation that allows predictable expected appreciation rates. This paper also builds upon the literature in the return and risk characteristics of real estate (see Bond et al, 2003, Capozza et al, 2002, Capozza et al, 2003, Capozza et al 2004, Case et al, 1999, Goetzmann, 1993 by investigating the sources of the volatility of housing markets. It also builds upon the literature on the relations between the housing market and economy and demographics (see for example Case and Mayer, 1996, Clapp and Giaccotto, 1994, Dispasquale and Wheaton, 1994, Leung, 2003, Quigley, 1990, and Reichert, 1990, among others) because the dynamical interrelations between the housing volatility and economic and demographic variables are studied.…”
