GENERAL EQUILIBRIUM OF SPATIAL PRODUCT AND LABOR MARKETS*

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.     

Location Equilibrium for Cournot Oligopoly in Spatially Separated Markets

Consider a two-stage non-cooperative Cournot game with location choice involving n≥ 2 firms each with several facilities. There are m≥ 2 spatially separated markets constituting the vertices of a network. Each firm first selects the locations of their facilities and then selects the quantities to supply to the markets to maximize its profit. There exists a Nash equilibrium in the quantities offered by each firm at the markets. Furthermore, when the demand in each market is sufficiently large, each firm chooses to locate its facilities only at vertices. With linear demand in each market, there exists a Nash location equilibrium.     

Public policy,local labor demand,and migration in Sweden, 1979-84

"A model of private local labor demand and interjurisdictional migration is presented and estimated using data from Swedish counties and municipalities for 1979-84. Our goal is to compare the effects on local labor markets of distinctive public-sector programs with those of traditional market variables. We find that local income taxes and tax-equalization grants have important effects on local labor markets; regional development policy measures and geographical-mobility subsidies do not. Thus, recent efforts scaling back some of these programs may not materially alter the regional economy's performance. Wages and other traditional market variables are also often found to influence significantly local labor markets."     

Duopoly prices under congested access*

Abstract. Consider two firms, at different locations, supplying a homogenous good at constant marginal production cost. Consumers incur travel costs to the firm for each unit purchased, and the travel costs increase with the amount of travel to each firm (congestion). When all traffic and all congestion are generated by travel to a duopolist, both the Nash–Bertrand equilibrium prices and the Nash–Cournot equilibrium prices exceed the sum of the marginal production cost and the marginal external travel cost. However, when the road is shared by travelers to the duopolists' facilities and travelers in competitive markets, the Nash–Bertrand duopoly price equals the competitive price and the Nash–Cournot price contains a markup.     

THE EXCHANGEABILITY OF HEDONIC PROPERTY PRICE STUDIES*

ABSTRACT. Observations drawn from multiple markets are essential to the construction of indices of housing costs and to measures of demand for housing attributes. It is not evident when multiple markets exist or whether such markets exist for some attributes but not for others. We test for multiple markets by using Bayesian methods to assess the transferability (random exchangeability) of entire hedonic price expressions from one site and time to another, the transferability of hedonic price functions for particular attributes, and the degrees of similarity that hedonic price functions must have in order to be transferable. In our illustrations, price functions for structural housing attributes are generally transferable; prices for neighborhood attributes are not. Therefore, in our illustrations, the desired price indices and demand functions should be estimable for neighborhood attributes, but not for structural ones.     

Long–Run Industry Equilibrium Under Demand Uncertainty: The Locational Effect of Business Taxes

This paper departs from previous work on the locational effects of business taxes under uncertainty by considering the attainment of long–run industry equilibrium. A general m input, planar–space production location model is adopted, and each individual firm is assumed to face random industry demand. I provide some interesting results which are contrary to those proposed by previous studies in the single–firm context and the relative impact of various business taxes.     

A Review of Volume 5 of the Handbook of Regional and Urban Economics,Parts III and IV

This paper reviews parts III and IV of the recent Handbook of Regional and Urban Economics. Many of the surveys within the Handbook relate to two phenomena of interest: the recent boom and bust cycle in U.S. housing markets, and the striking growth of home prices in a few global “Superstar Cities.” Real Estate and Urban economists have made progress in modeling these phenomena. There is considerable room for future research, however. There is no coherent story explaining U.S. home price movements in the 2000s that does not run afoul of important stylized facts. We also have not yet identified the relative importance of supply constraints and demand growth in the rise of Superstar City prices.     

SEARCH FRICTIONS,UNEMPLOYMENT, AND HOUSING IN CITIES: THEORY AND POLICIES

We propose an urban search‐matching model with land development. Wages, unemployment, prices of housing and land are endogenously determined. We characterize the steady‐state equilibrium and then discuss the issue of efficiency. To explore interactions among markets, we implement comparative static analysis. We also consider three policies: an entry‐cost policy that reduces firms' entry, a transportation policy that reduces commuting costs, and a housing policy that decreases rental prices. We find that the transportation and housing policies are more efficient if the unemployment rate is low, while the entry‐cost policy is more efficient if the unemployment rate is high.     

ECONOMIC IMPACTS OF CULTURAL DIVERSITY IN THE NETHERLANDS: PRODUCTIVITY,UTILITY, AND SORTING*

ABSTRACT This paper identifies the impact of cultural diversity on local economies, by explaining spatial disparities in wages and housing prices across Dutch cities using unique individual panel data of homeowners during the period 1999 and 2008. We distinguish between the effects of spatial sorting based on individual heterogeneity, interactions‐based productivity effects, and consumer amenities while controlling for interactions between the labor and housing market. In line with previous literature, we find a positive effect of cultural diversity on average housing prices. After controlling for spatial sorting, the effect of cultural diversity on housing prices is negative. The negative impact of cultural diversity on local housing markets is likely driven by a causal effect between the presence of immigrants and neighborhood quality that outweighs a positive effect of immigrant‐induced diversity in consumption goods.     

THE LAW OF ONE PRICE IN A NETWORK: ARBITRAGE AND PRICE DYNAMICS IN NATURAL GAS CITY GATE MARKETS*

ABSTRACT. In this paper we develop a model of the law of one price in a network where many markets are linked with a structure of paths. We show that arbitrage-free prices depend on the structure of the network and so do price dynamics. Our estimates indicate that local bypass and open access pipeline transportation were instrumental in opening arbitrage paths to natural gas city markets and causing their prices to converge. Spot markets in the city gates, pipeline hubs, and production fields, that are scattered over distant points in the vast pipeline network in the United States, now form a single market.     

ECONOMETRIC ANALYSIS OF HOUSING TRAIT PRICES IN A THIRD WORLD CITY*

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 briefly.     

PRICE UNCERTAINTY,FACTOR SUBSTITUTION,AND THE LOCATIONAL BIAS OF BUSINESS TAXES*

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.     

THE IMPACT OF STATE LAND-USECONTROLS ON RESIDENTIAL LAND VALUES

In this paper, we examine the effects of state land-use controls on the aggregate demand and supply of residential land. Previous studies have examined the effect of land-use regulation on housing prices using single-equation estimation. We estimate a three-equation intejurisdidional supply-demand model of land-use controls. Our results suggest that land-use regulations have a significant impact on both the demand and supply of residentid land as expected.     

TWO-EARNER FAMILIES IN THE HOUSING MARKET

The 1970's has been a period in which three trends have coincided: housing prices have been escalating, wives have continued to enter the labor force, and legislation prohibiting discrimination in mortgage markets on the basis of sex and marital status has been enacted. In this paper, we examine the role of the two-earner family–one in which both husband and wife work–in the housing market of the 1970's, and the interrelation of this household type with other factors shaping the current high demand for housing. We also speculate on the role of the two-earner family in the housing market of the 1980's. We conclude that two-earner families are in a position to increase their housing outlays in the future, that the continued growth in the number of two-earner families will add to future housing demand, but that many two-earner families may be divorced couples of the future. This suggests that, while there will be a strong impact on single-family home demand, there will also be some restructuring of demand toward rental housing and cooperative/condominium ownership.     

DOES AGGLOMERATION MATTER EVERYWHERE?: NEW FIRM LOCATION DECISIONS IN RURAL AND URBAN MARKETS*

We test whether commonly used measures of agglomeration economies encourage new firm entry in both urban and rural markets. Using new firm location decisions in Iowa and North Carolina, we find that measured agglomeration economies increase the probability of new firm entry in both urban and rural areas. Firms are more likely to locate in markets with an existing cluster of firms in the same industry, with greater concentrations of upstream suppliers or downstream customers, and with a larger proportion of college‐educated workers in the local labor supply. Firms are less likely to enter markets with no incumbent firms in the sector or where production is concentrated in relatively few sectors. The same factors encourage both stand‐alone start‐ups and establishments built by multiplant firms. Commuting decisions exhibit the same pattern as new firm entry with workers commuting from low to high agglomeration markets. Because agglomeration economies are important for rural firm entry also, policies encouraging new firm entry should focus on relatively few job centers rather than encouraging new firm entry in every small town.     

沉没成本、制度环境与企业出口地理动态

本文使用2002-2011年中国海关出口数据,探究成本视角下企业出口地理动态和作用机制。实证结果表明企业出口活动和邻近企业溢出均对企业在出口市场上的进入和退出存在显著双面性影响：企业出口活动不利于企业进入新市场,但利于企业继续留在国外已有市场中;邻近企业溢出为企业进入新市场创造了有利条件,但加快了企业从已有市场退出。本文还发现在市场化程度较低和政府干预程度较高的地区,企业出口活动和邻近企业溢出发挥的“双面性”影响明显。这意味地方制度环境能影响中国企业出口地理动态,塑造了企业出口的动机和策略。     

HOTELLING'S “MAIN STREET” WITH MORE THAN TWO COMPETITORS*

ABSTRACT. I analyze oligopolistic competition among three or more firms located on Hotelling's (1929) Main Street and show that in contrast with Hotelling's duopoly, the symmetric locational structure supports a noncooperative equilibrium in prices. However, in a two-stage game of location choice in the first stage, and price choice in the second stage, there exists no subgame-perfect equilibrium where the whole market is served. This is because, starting from any locational pattern, firms have incentives to move toward the central firm. This strong version of the Principle of Minimum Differentiation destroys the possibility of a locational equilibrium. The results are a direct consequence of the existence of boundaries in the space of location. The sharp difference between these results and those of the standard circular model (whose product space lacks boundaries) shows that the general use of the circular model as an approximation to the line interval model may be unwarranted.     

Testing for the Law of One Price and Identifying Price-Leading Markets: An Application to Corn Markets in Benin

A data-determined method is proposed to test for the law of one price as a long-run equilibrium condition and to identify which markets in a network of spatially dispersed commodity markets quote the reference price. The method consists of supplementing Johansen's FIML cointegration procedure with a permanent-transitory decomposition and rules of inference in linear time-series models with unit roots. As an example, we apply our method to prices of six corn markets in Benin. We find that the law of one price holds in the long-run. It appears that two rural markets quote the reference price: their prices adjust fastest towards the permanent change induced by the common stochastic trend.     

The external effects of inner-city shopping centers: Evidence from the Netherlands

Shopping center redevelopment is inevitable to remain attractive for consumers. In this paper, we investigate the external effects of shopping center redevelopment on nearby residential property prices. Using a difference-in-difference empirical framework, we find the redevelopment has positive external effects on nearby property prices. We find the price of a property located next to a redeveloped shopping center increases by 1.43% on average just after redevelopment. Our results indicate that these positive external effects wear off rather rapidly across space and over time. This suggests that shopping center redevelopment plays a substantial, but limited, role in combating neighborhood deprivation.     

A MANAGERIAL MODEL OF THE EFFECT OF PRODUCT MARKET STRUCTURE ON FIRM LOCATION*

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.
