To assess the local effect of a land use zone in each place, hedonic equation of land prices is estimated using geographically weighted regression (GWR) that allows estimation of locally varying but spatially continuous parameters. An experiment for Sendai Metropolitan Area (Miyagi, Japan) reveals that the effects of land use zones indeed vary, and in some locations even the more restrictive zone designation raise the price of that land than designated otherwise. Based on the equation, the zone that maximizes the price of land for each location can also be identified. While GWR seem to be a usefull tool in evaluating and designing urban land use planning, the experiment in this paper also reveals that obtaining robust result is difficult, and further research is necessary to specify variables and fuctional forms for reliable estimates.

Squatter settlements are known to reduce house prices nearby, but we find that their effects are far from homogeneous in the city. To identify such varying effects, we used geographically weighted regression (GWR), which allows for the regression coefficients to vary over space. In the City of Buenos Aires, we found that the negative effect of the proximity to the squatter settlements is stronger in higher income neighborhoods while that in the lower income neighborhoods were weak or insignificant. We also found that a squatter settlement in a strategic area can be an opportunity to redevelop into a highly productive area, thereby raising the house prices nearby through speculation. These findings suggest that policies to improve a squatter settlement are not only in the interest of its residents, also but of the high-income households in the...
