| Research Abstract |
The importance of economic space has not been recognized in the traditional microeconomic theory. This neglect of economic space entails enormous opportunity costs. The effects of imperfect competition and that of the structure of spatial markets on the equilibrium have not been intensively studied in formal models.
This paper investigates the relationship between the spatial equilibrium and the structure of regional markets. We consider a formal model incorporating competitive as well as imperfectly competitive markets into it. These different types of spatial markets are substitutable, and the relative importancesbetween the markets are endogenously determined in the regional equilibrium. Consumers and firms- can choose markets where they sell or purchase products in order to maximize their profits. Relative price rigidity depends on the location of firms as well as that of consumers. By formulating a general equilibrium model with product and labor markets in urban areas, we derive new economic implications for regional policies. It is worth noting that the effects of regional policies on prices and employment are sharply different from those of macroeconomic policies. In order to conduct regional policies successfully, the usual results about macroeconomic theory should not be easily extended to the spatial setting.
