A residential choice model of social prejudice

This study suggested an extended model of residential choice embeded social prejudice impact. Especially, this study regarded social prejudice that could be generated between income classes as externality and focused on how prejudice between the highincome class and the low-income class impacted on a residential choice of each class, how prejudice impact changed an urban structure, and what had an effect on the utility of the city. A land use theory by Fujita (1989) and a racial externality model of residential choice by Bailey (1996), Courant (1978), and Yinger (1976 and 1978) are based on a model of study. Consequently, there are remarkable changes of bid rent curves between the pattern of the city which is affected by a social prejudice impact and that of the unaffected city. Also, there are some differences according to which class is affected by the prejudice impact. The consequence is that a simple supply-centered policy standing for social mix and a mechanical and cursory interpretation are insignificant, and various and efficient methods that reduce a social prejudice impact between the income classes in the city, can improve the utility of the whole city.
