ON THE OPTIMUM LOCATION OF VERTICALLY RELATED FIRMS WITH SIMULTANEOUS ENTRY*

ABSTRACT This paper considers a case of bilateral monopoly and examines the possibility of an intermediate location for two vertically related firms under simultaneous entry, and then analyzes the welfare-maximizing location for both firms. It shows that whatever the case, an intermediate location for both firms is unlikely to occur and that the pattern of industrial location under welfare maximization is equivalent to the one under perfect competition, but is different from the one under bilateral monopoly under certain circumstances.     

OPTIMUM LOCATION AND THEORY OF THE FIRM UNDER A REGULATORY CONSTRAINT*

This paper attempts to incorporate space in the theory of a regulated firm. It will show that the A-J effects are not affected in a spatial setting. In addition, it will also demonstrate that as the difference between the regulated fair rate of return and the unconstrained profit-maximizing rate of return on capital becomes greater, the optimum location of the regulated firm moves towards the site of the product market, if capital and labor are complements (substitutes) and if marginal transportation costs (with respect to distance) are an increasing (decreasing) function of labor usage.     

A NOTE ON TRANSPORTATION RATES AND LOCATION OF THE FIRM IN A TWO-DIMENSION,n-INPUT SPACE*

This paper examines the theoretical implications of quantity-discounted transportation rates on the optimum location decision of the firm. It shows that the linearly homogeneous or homothetic production function is not a sufficient condition for the independence between the optimum location and the output level, unless (i) the elasticities of transportation rates with respect to quantity shipped are constant and identical, and (ii) the ratios of marginal products 60 the marginal transportation costs are equal for each input.     

A NOTE ON THE LOCATION OF MEDICAL FACILITIES

In this note, I present a method to estimate the desired distance between medical facilities. The survival rate of patients improves when the facility is larger, however larger facilities result in a longer driving distance to the facility which decreases the survival rate. I identify the desired distance between facilities for which the survival rate is maximized.     

A NOTE ON MULTIPURPOSE AND MULTISTOP SHOPPING,SALES, AND MARKET AREAS OF FIRMS*

ABSTRACT. The paper characterizes the aggregate demand addressed to firms in a situation such that consumers are allowed to purchase during the same journey several commodities from several firms located in a one-dimensional space. It is a duopoly in which both firms sell the two commodities. The individual demand is assumed to be price-inelastic.     

OPTIMUM LOCATION OF PUBLIC FACILITIES UNDER THE INFLUENCE OF THE LAND MARKET*

ABSTRACT. This paper discusses the problem of the optimal location of public facility(ies) in a long narrow city, especially taking into consideration the externality-internalizing effect of the land market. It shows a systematic approach to dealing with the land market mechanism in first a one-facility and then a two-facility case. The analysis assures the importance of posing the location-optimizing problem even under the influence of the land market.     

A NOTE ON NEIGHBORHOOD SIZE AND THE MEASUREMENT OF SEGREGATION INDICES*

This note examines neighborhood segregation measures with respect to size and validity. Conventional measures, while related to within-neighborhood homogeneity, are not necessarily related to neighborhood size. An empirical test examines racial segregation for Baltimore in 1970 and 1980 using both census tract and specially formulated neighborhood aggregates. For both years, and for all measures of segregation, the values and trends are essentially unchanged by the level of aggregation.
