Chapters 2-5 analyse house prices across Chinese prefecture cities (city-level gradients, SLX/SDEM/SDM/SAR, convergence/cointegration) - aggregate unit of analysis, NOT extracted. Chapter 6 ('builder's model', Diewert et al.) estimates annual dwelling-level hedonic models for the Dutch city 'A'; only the 2007 structure-characteristic estimates are printed (Table 6.1, PDF p.168, printed p.148). Dependent variable = transaction price per m2 of living space (EUR), regressed on the ratio plot size/living space (land price, EUR per m2 of land) and dummies for building period and house type; coefficients are in EUR per m2 of living space relative to a detached house built after 2000 (intercept = structure price of the reference). OLS = common land price; OLSD = land price varying by 9 postcode areas (multiplicative dummies); MGWR = land price by GWR (adaptive bi-square, 60 nearest neighbours) with global structure coefficients. Standard errors in parentheses; *** 1%, ** 5%, * 10%. 'Building period' dummies are a vintage (year-built) classification, mapped to age. Land price for the 2007 OLS model (214.87 EUR/m2) taken from Table 6.2 (p.169), no SE. location_fe=true refers to OLSD/MGWR only."
