“…Many studies have simply presented analyses of appraisal-based returns without correcting for the effect of smoothing (e.g., Brueggeman, Chen, and Thibodeau, 1984;Miles and McCue, 1984;Miles, 1986, 1987;Hartzell, Shulman, and Wurtzebach, 1987). Other studies have attempted to correct for appraisal smoothing by developing simulated returns series, either by applying cap rate time series to real estate income time series (e.g., Firstenburg, Ross, and Zisler, 1988;Wheaton and Torto, 1989;Liu, et al 1990), or by using so-called "transactions driven" indices of real estate returns based on hedonic models of real estate fundamental value (e.g., Hoag, 1980;Miles, Cole, and Guilkey, 1990). But these simulated returns inevitably contain considerable noise since the cap rates or hedonie models employed to generate the returns are subject to error?…”
