Dual Labor Markets, Urban Unemployment, and Multicentric Cities
构建了一个城市就业的两部门模型，分析初级部门需求冲击如何催生次级部门，并导致多中心城市空间结构。研究发现新均衡可能降低失业并提高失业者净收入，且初级部门有动机补贴次级部门进入。
A two-sector model of urban employment is developed which focuses on the formation of a secondary sector in response to a primary-sector demand shock. The optimal location of this (single-firm) sector is shown to give rise to a multicentric urban spatial structure. Conditions are then established under which the new labor market equilibrium involves both a decrease in unemployment and an increase in net income for those unemployed. These results are extended to a case where all unemployment benefits are financed by local taxation of firms. Here it is shown that profit incentives may exist for the primary sector to subsidize entry of the secondary sector.Journal of Economic LiteratureClassification Numbers: J41, R14.
