Rapid urbanization in developing countries has produced a heavy concentration of population and economic activity in a very few large urban centers. This pattern of urban concentration has generated two major policy concerns: (i) keeping the largest cities in these countries from getting too large, and (ii) maintaining regional equity. This paper reports the empirical findings from the Bogota City Study and draws some policy conclusions in the context of Korean spatial policy experience. It documents the observed decentralization trends of employment in Bogota and Cali using several sets of household survey data and the Colombian social security data. Then, it summarizes the theoretical and empirical framework developed for the location choice of manufacturing firms. Drawing on these behavioral underpinnings of the firm's location choice, the paper evaluates several policy issues related to employment decentralization based on the policies implemented in the Seoul region.
