ABSTRACT.The premise of this paper is that one can discover much about the location determinants of high‐technology industry by examining the location (migration) decision of workers with high‐technology occupations. A model of the high‐technology worker migration decision is developed that permits estimation of worker response to both personal and area characteristics, the latter chosen to mirror location factors often cited by high‐technology firms as important for both the attraction and retention of their specialized work force. Logit estimates of this model between 1975 and 1980 are presented. The paper is concluded with a discussion of policy impli

ABSTRACT.It is shown that, under some very mild conditions, maximum likelihood estimates of gravity model parameters exist and are unique (up to a scale transformation for some parameters). An algorithm for finding such estimates is also proposed.

摘要:

ABSTRACT.Congestion and pollution externalities from automobile use are simultaneously included in an urban monocentric model. The externalities enter household utility functions directly, and result in a complex interdependency in household location decisions in the city. Implications of the model are drawn out by a simulation and complete sensitivity analysis. The two unpriced externalities are examined for their impact on urban structure, and contrasted with each other. Also, the effect of changes in speed of travel are examined for the impact on urban structure. Speed affects the level of both external effects, and is affected by location decisions.

ABSTRACT.This paper estimates a flexible frontier specification for the production of urban bus transit services in the United States. The results confirm previous findings of relatively unimportant scale economies. However, they also suggest that this regulated industry is subject to substantial technical and allocative inefficiency.

摘要:

ABSTRACT.This paper presents a probabilistic specification of coefficients in the input‐ output modeling framework. Although previous works on probabilistic input‐output models attribute uncertainty to measurement and sampling errors, this specification derives from systematic variation directly attributable to industrial, institutional, and location factors. Experiments with national input‐output data support the existence of such variation. Employing the specification not only yields a more flexible aggregate modeling framework capable of producing interval impact estimates, but also an alternative perspective on such issues as interregional differentiation and structural comparison, the identification of key industrial sectors, aggregation, and spatial variation in produ

摘要:

ABSTRACT.A first step in the process of economic analysis of housing markets in Third World cities is the econometric analysis of housing trait prices. The information on market price of housing is basic to the derivation/estimation of other market parameters such as housing demand and supply elasticities. In addition, housing trait prices constitute invaluable inputs into the analysis of effects of government housing programs.This paper presents estimates of housing trait prices in a Third World city housing market, the city of Jos in Nigeria. Nonlinear stochastic specification of a policy constrained hedonic price function is presented as an unbiased estimator of housing trait prices. The Box‐Cox statistical procedure was employed in the paper to obtain hedonic regression coefficients which are the parameters needed to compute the average prices evaluated both at the mean of each trait and at their margins. The potential uses of housing trait prices for policy analysis are discussed briefl

摘要:

ABSTRACT.This paper presents a new approach in the modeling of residential choices for simulation purpose. The originality of the approach resides in the way recent developments in stochastic choice models are combined with deterministic mathematical programming which allows to define an equilibration process for simulation. In that respect, ex ante probabilities of housing choice based on random utility maximization under perceived constraints are distinguished from ex post probabilities of choice that respect supply constraints. The proposed model is tested on the Montreal Metropolitan Region, and a few simulation results based on a scenario of population aging and decrease in household size are analyzed.

摘要:

ABSTRACT.This paper presents a statistical procedure for empirically establishing linkages between regional economies. Using Granger's definition of causality and the final prediction error technique for lag‐length specification suggested by Hsiao, a linked, multiregional employment model is developed. The forecast performance of the linked model is compared to models which do not include interregional linkages. It is shown that forecast error is reduced by taking into account employment interrelationships between region

摘要:

ABSTRACT.This paper examines the mechanism and extent of urban concentration using a two‐sedor growth model. The cause of urbanization is sought in the existence of urban scale economies. Assuming that temporary production decisions are concerned with optimal labor inputs and that profit incomes are reinvested according to relative profitability, the model shows persistent tendency for urban concentration and the transition of the economy from unlimited to limited labor supply. A simple example suggests that urban concentration is more likely than rural expansion with urban contractio

摘要:

ABSTRACT.This paper investigates the assumption of homogeneous labor inputs underlying the production functions in many regional models. The results indicate that nonproduction and production labor within manufacturing plants are not strongly separable, and the homogeneous labor assumption is not therefore appropriate. Hence, regional models need to take this into account in order to give reliable results. Differences between industries provide useful additional insights into their labor and capital relationships.
