A comparative static analysis of urban spatial structure

摘要: More than a decade has passed since Alonso published his general theory of the urban land market [l]. In intervening years, number other authors have also developed equilibrium models rent and density [2]. While structure these been much discussed, there virtually no comparative static analysis done on them. The only exception is Mills’ recent numerical city with specified functional forms parameter values [3]. work excellent in scope, reliance Cobb-Douglas functions would seem to limit generality results. pm-pose this paper conduct truly two density. Unlike authors, we use utility function whose requirement that both goods be “normal” positive income effects. This assumption sufficient determine sign all our spatial systems, viewed as small part national economy. production services occurs at center, but wages, prices, costs commuter travel are exogeneous. Consumers who center earn same identical preferences. As others, locational choice essentially represents tradeoff between travel. first cities “closed” sense population size exogeneous, while consumer levels welfare must determined within system. situation typical industrially advanced societies, where alternative living areas. underdeveloped countries, however, rural life often establishes base-line level welfare.
