ABSTRACT. In a simple urban model, where the only spatial distinction made is between center and suburb, we introduce a uniform distribution of preferences for land. Under a logarithmic utility function, we examine how the location and consumption decisions of individuals differ in consequence of their different preferences for land. Comparative statics indicate that the qualitative response of the city at equilibrium to changes in per capita income and transportation cost is not affected by the introduction of such heterogeneity. Possible extensions are also briefly discussed.  相似文献

ABSTRACT. This paper uses a large data base to study metropolitan labor demand functions. The data are disaggregated by two-digit SICs in manufacturing for SMS As, and are corrected for changing SMSA boundaries. Labor demand elasticities are estimated for factor and commodity prices, transportation costs, state and local taxes and expenditures, and production-function shifters. Estimates from different years allow one to test Le Chatelier's principle in the context of interregional change.  相似文献

Mapping population data from zone centroid locations   总被引:1,自引:0,他引:1  
The author describes the difficulties associated with the use of maps to represent census data. "A review of the problems associated with population mapping is followed by a discussion of [an alternative method known as] a raster method for handling census data, based on population-weighted centroids, and its implications for GIS "[geographic information systems]." The geographical scope is worldwide, with an example provided using data for Wales.  相似文献

The NSW doctors’ dispute 1984–85 has had a lasting effect on the Australian health care system. Militant surgeons were effective in securing some modifications to regulations and administrative arrangements governing the role and remuneration of certain groups of doctors in NSW public hospitals and some changes to the federal government's Medicare scheme.

This paper examines the causes, actors, issues and outcome of the dispute. The key to understanding the dispute is a knowledge of both the specific issues debated by militant doctors and the federal and NSW Labor governments and the broader historical forces that have shaped the politics of national health insurance throughout the twentieth century. In contrast to media reports, the outcome of the dispute is interpreted as a compromise rather than a victory for the doctors. It is further argued that a theoretical generalisation formulated by two American political scientists, Marmor and Thomas, about disputes between doctors and governments over payment methods is only partially useful in explaining the outcome.

Two prominent and well‐documented historical themes from the politics of national health insurance in Australia — namely, the resistance of sections of the medical profession to any contraction of the private market for medicine and the fragmentation of the organised medical profession during periods of disputation with governments at the state and federal level — are discussed. These themes, and some generalisations about the capacity of the medical profession to influence public policy outcomes, are illuminated by the study.  相似文献
