ABSTRACT A simple general equilibrium model relates spatial product markets and spatial labor markets. The firm is treated as being a spatial monopolist or as a Löschian competitor in the output market and as a spatial monopsonist in the labor market. Derived free spatial demand and free regional labor supply are defined, and their properties examined. The model provides the framework for analyzing the impact of a technological improvement in labor productivity on the structure of the spatial markets. The impact of entry on spatial labor supply is an important determinant of whether or not entry lowers wages and raises output prices. Unlike the spaceless competitive paradigm, zero-profit long-run equilibrium can occur in a space economy under conditions of increasing returns to scale. 相似文献

ABSTRACT. Recent research suggests that in nonmonocentric cities compensation for commutes takes the form of both lower housing prices and higher wages. This paper develops a random utility model that predicts the probability of an actor choosing to commute between each residence and job in a metropolitan area conditional on the observed location of housing units and job sites. The model allows commuting time, origin-specific amenities, land prices, destination-specific amenities and wages to influence actors' choices. We estimate the model using maximum likelihood and generalized least squares techniques and data on commuting between each of 38 origin and 15 destination jurisdictions in the Tokyo metropolitan area. The empirical results show that, all else equal, a one percent increase in commuting time reduces the probability that a route (origin-destination combination) will be chosen by almost five percent. Origin-specific amenities are not completely capitalized into land prices and destination-specific amenities are not completely capitalized into wages. Desirable residential amenities include school quality and a low ratio of day to night population. Desirable workplace amenities include a large share of white collar jobs and a high density of employment. 相似文献

ABSTRACT. This paper develops a model of firm location choice based on managerial theory of discretionary behavior. Specifically, it is assumed that the management of the firm maximizes a utility function which incorporates profits and location-specific amenities. As the firm moves from one prospective location to another, it faces a profit-amenity constraint imposed by market conditions. The optimal location decision is derived by maximizing the utility function subject to this market-imposed constraint. After examining the properties of the optimal solution, the impact of various changes in product market structure (including changes from a contestible markets perspective) on the location decision is investigated. A major finding is that the impact of a change in market structure depends upon the nature of the structure change and upon the substitution and income effects induced by the structural change. 相似文献

Few attempts have been made to develop and test a conceptual framework for the comparative analysis of urban spatial structure and growth. This paper offers one aggregate approach as well as a series of empirical tests based on Canada's 27 largest urban areas. Six composite indices are introduced: population densities, rates of change, intraurban population redistribution, mobility rates, incidence of low-income populations, and degree of social polarization. Regression analyses reveal that differences among urban areas in spatial patterning and structural change are consistent with the hypothesized effects of city size, age, transport usage, social heterogeneity, production base, and physical setting. Yet immense regional and intraurban diversity remains. No single model of urban structure is sufficient to capture this diversity. On enregistre peu de tentatives pour mettre au point et tester un cadre conceptuel qui puisse servir à I'analyse comparative de structure spatiale et de croissance urbaine. Get article offre une approche g/oba/e ainsi qu'une série d'analyses empiriques basées sur les 27 territoires urbains canadiens les plus grande. Six indices composes servent aà l'analyse: densité de population et taux de changement de ces densités, redistribution et taux de mobilité de la population intra-urbaine, incidence de revenus faibles et importance de la polarisation sociale. Les analyses de régression démontrent que les différences dans l'arrangement des espaces et le changement des structures entre les zones urbaines sont en accord avec les effets supposés de taille urbaine, d'âge, d'utilisation du transport, d'hétérogénéité sociale, de base de production et de cadre physique. Cependant, une très grande diversité régionale et intraurbaine de-meure, II n'existe pas un seul modèle de structure urbaine capable d'englober cette diversité. 相似文献

ABSTRACT. This paper proposes a procedure with which sectoral production functions can be aggregated to metropolitan production functions in the presence of external economies of scale. The procedure specifies the production functions as part of general equilibrium models. Consistency of a one-sector and a two-sector general equilibrium model is defined in terms of equality of the distribution of a nation's population over its metropolitan areas in autarky. 相似文献

ABSTRACT. Data for 28 metropolitan areas over a 15-year period are used to determine the impacts of government spending, taxes, and public infrastructure on total employment and disaggregated employment. After carefully controlling for the government budget constraint we find that taxes are negatively related to total employment and education spending is positively related to total employment. Nevertheless, we find that it is difficult for metropolitan areas to influence the composition of their employment with government tax and expenditure policies. Moreover, at current levels of public infrastructure, marginal changes in infrastructure have no strong effect on employment. 相似文献

ABSTRACT. This article examines how a metropolitan area's job growth affects its income distribution, using CPS data from 1979 to 1988. Metropolitan growth increases the poorest quintile's income by a greater percentage than for the average family. Metropolitan growth also increases the value of property owned by the richest quintiles. Economic development programs to increase local growth will have a net progressive effect if the cost per job created is low, and these costs are financed by personal taxes. But programs with a high cost per job, or financed by cutting welfare, will reduce the net income of the poorest quintile. 相似文献

ABSTRACT The Todaro paradox and the effects of job creation in urban areas will be re-examined in our spatial model in which the radius of the labor market is endogenously determined by the rational choices of workers. The travel cost of workers plays a crucial role in the choice between two different types of response, migration or commuting. By considering travel costs, we find that the Todaro paradox can be applied to developed, as well as developing, countries. Job creation in urban areas can produce a paradoxical increase in urban unemployment in developed countries, because the low marginal cost of travel will significantly increase the radius of the urban labor market and create new labor supply without migration. 相似文献

In this paper, I model a simple hierarchical inter-urban system in which the location of business firms is considered together with the determination of residential land-use patterns. By supposing a spatial externality between the business firms and all the residents of the region, three spatial structures are obtained: monocentricity, multicentricity, and a separate pattern where cities are spatially split with an agricultural land existing between them. It is also shown that the spatial structures of monocentric and multicentric patterns formed by the market principle tend to be more concentrated than the optimum. 相似文献

Consideration of the integrated production-location problem is extended to include several types of business taxes. Many of these taxes are technologically and spatially neutral under certainty, but are shown to be nonneutral when factor prices are stochastic and the firm is risk averse, even when the tax is spatially uniform. Consequently, even a nationally uniform tax can have regional biases and can encourage migration of plants. When factor prices are uncertain, the effects of taxes on output rates, input ratios, and plant location vary with the form of the tax imposed as well as the amount to be paid. Income taxes involve the taxing authority in sharing the risk with the firm and are shown to promote risk taking by the firm and induce the expansion of output. Locational incentives which are mutually beneficial to firms and the government are presented. 相似文献

ABSTRACT. This paper uses new estimates of metropolitan factor demand and output supply functions to study how federal, state, and local fiscal policies affect metropolitan economies. We illustrate our work with findings for ten metropolitan areas in five states for changes in state corporate income taxes, local property taxes, the federal corporate income tax, an investment tax credit, interest rates, public capital stocks, output prices, and tax and regulatory policies affecting gross wages. It is clear from these simulations that a policy that is nominally the same everywhere will have repercussions that vary widely across regions and cities. 相似文献
