Intrametropolitan migration: A simultaneous model of employment and residential location of white and black households

Abstract

This study explores the relationship between the home and job location of the household within a metropolitan area. The model is an extension of the Alonso-Muth framework and allows the household to simultaneously choose its residential and employment location, monthly rent, number of rooms and the type of structure of the dwelling unit, so as to maximize its utility subject to the budget constraint. The data base is the Home Interview Survey conducted in 1965 by the (San Francisco) Bay Area Transportation Study Commission. The coefficients in the simultaneous model are estimated by two-stage least squares. The cross-section sample is stratified by tenure into renters and homeowners; by race into black and white households; and further by position in the life-cycle. The results of the location equations reveal that both the home and job location are responsive to each other which implies that the decentralization of jobs will result in the decentralization of residences for black households. The results of the housing equations imply that black and white households have almost identical elasticity of demand for housing. There is very slight evidence of price discrimination against black households. However, there is evidence that black households do face a geographical segregated market for rental housing. The results of this study argue that the decentralization of population is not due solely to rising incomes and will continue as long as industry decentralizes. Furthermore, governmental policies of increasing the income of central city residents, through subsidies to employers to locate in the central city will have a strong effect: inducing those residents to remain in or move into the central city. Thus, a policy that is meant to alleviate the plight of the city center may only result in strengthening the racial and income split between the suburb and the central city inhabitants.
