Does the Structure of an Urban System Affect Income Disparities?

In this paper I analyze the impact of basic training and specialized training on the distribution of skill, income disparity, social welfare, and on the structure of a decentralized specialized city system. This is done in a spatial general-equilibrium model of a closed economy producing a single consumption good. The economy is populated with a continuum of unskilled labor with potential heterogeneous ability. The only consumption good can be produced by specialized technology or by general technology. Specialized technology requires specialized training that enables each worker to transform his potential ability into productivity. General technology requires basic training that enables all workers, independent of their potential ability, to produce the good at a constant marginal product. In this framework I show that such an equilibrium exists uniquely and is efficient. Then I characterize the conditions that lead to a different distribution of skills, a different system of cities, and generate income disparity endogenously. Thus, the paper presents a link among income disparities, social welfare, and the structure of an urban system that is new to this literature.     

Migrant household homeownership outcomes in large Chinese cities - the sustained impact of hukou

Homeownership by migrant households in large Chinese cities is increasingly evident and sometimes blamed for driving up local housing prices. Hukou reform grants local hukou to migrants in small cities while it allows large cities to set up hukou entry barriers to control migration. This paper explores whether migrant households’ micro-level characteristics and macro-level urban policies relating to hukou reform have any impact on their housing tenure choices. Using data from a 2009 survey of migrant households in six large cities, this study adopts logistic regression models to examine factors influencing labor migrant households’ tenure decisions. We find that household income and head of household hukou type, contribution to pension fund, and enrollment in health insurance all positively predict homeownership. Migrant households are more likely to be found in cities with larger population size. We argue that city entry barriers create new forms of institutional haves and have-nots and new forms of inequality. The sustained impact of previous hukou types suggests inherited inequalities through intergenerational wealth transfer, which calls for targeted welfare policies to mediate.     

乡村旅游对农户农林业生产和外出务工影响研究——基于陕西22个旅游扶贫村农户调查数据

利用课题组2017年6-8月在陕西安康、商洛、汉中、宝鸡4市9县22个旅游扶贫村收集的841个农户调查数据，采用双重选择模型（DSM）等分析了农户参与旅游对家庭农林业劳动时间、外出务工时间的影响。研究发现，参与旅游有助于增加调查地的农户收入，旅游兼营型农户收入更高。在全样本中，参与旅游对农户农林业生产时间具有显著负向作用，但在参与了旅游的农户样本中，农户参与旅游一些特征或形式，如土特产销售，对农林业生产则有显著正向作用；在多个模型中，农户从事旅游对家庭外出务工活动具有显著的负向作用。提出了延长农业产业链、发展“旅游+农业”、促进农村一二三产业融合，提高景区带村作用、完善旅游扶贫政策等对策建议。     

Multi-Firm City Versus Company Town: A Micro Foundation Model of Localization Economies

When do we have a company town and when do we have a multi‐firm city? In this paper I analyze the impact of public infrastructure investment decisions on types of cities in a decentralized urban system. This is done in a one‐sector spatial general equilibrium model of a closed economy. Investment in public infrastructures reduces the fixed set up cost of all firms within the city resulting in multi‐firm cities. Thus, in this approach localization economies are modelled explicitly instead of assuming that larger industrial size within the city enhances productivity. On the other hand, when the infrastructure is not provided, a company town will be formed by a developer because of the fixed cost required by each firm. The decision of whether to invest in the provision of public infrastructures depends on the type of city that will provide households with the highest utility. This paper characterizes the conditions that lead to each of the two equilibrium configurations.     

A THEORETICAL EXPOSITION OF MIGRATION ENFORCEMENT ON EXISTING MIGRANT AND DOMESTIC HOUSEHOLDS*

ABSTRACT This paper presents a model with a domestic household and a heterogeneous migrant household in arrival timing. The domestic and documented migrant households divide their one unit of time between lobbying for/against immigration enforcement expenditures and employment. The analysis shows that an increase in public dislike for undocumented workers lowers domestic and existing migrant households private investment in own child education. It also causes average public expenditures on education to fall and leads to a negative impact on the educational outcomes of all households.

Preferences for Housing, Jobs, and Commuting: A Mixed Logit Analysis

This paper reports stated preferences of Dutch workers for combinations of housing, employment, and commuting. The analysis uses standard logit models as well as mixed logit models. Estimation results offer insights into the relative importance of various aspects of housing, employment, and commuting. Households dislike commuting and the value of commuting time implied by the model is high in comparison to the wage rate. Nevertheless, preferences for some housing attributes are strong enough to make substantially longer commuting acceptable to most workers. Of special interest is the strong preference for living in small-or medium-size cities, especially among two income households. Using a mixed logit model instead of a standard logit model results in a substantial improvement of the loglikelihood, reflecting the importance of heterogeneity among respondents. If no individual characteristics are incorporated into the model, the mixed logit implies substantially lower average monetary evaluations of most attributes. These differences are much smaller if some individual characteristics are incorporated into the model.     

SHARABLE INPUTS,PRODUCT VARIETY,AND CITY SIZES*

In this paper, I investigate some of the causes of city formation in spatial economies. A model is proposed in which an intermediate differentiated input shared by more than one industry is the cause of the formation of diversified cities. The desire of both the traded-good and the local-good industries to employ a variety of inputs from the intermediate industry provides the reason for the agglomeration of the three industries. In addition, the paper contains a comparative-statics analysis of the model in an open and a closed-city framework. It is demonstrated that the larger the city, the more variety of intermediate inputs the city can provide and the more specialized it is in the production of the traded-good. Moreover, the model suggests that different industrial structures will result in different city Sizes.     

Working,Shopping, and House Rents

The interaction between household demand for goods and for leisure and the supply of labor at various distances from an urban center is investigated for the case where rents are endogenous and adjust to equalize differences in utility produced by the greater time and money costs of the journey to shop and the journey to work. The model is solved for a set of realistic parameter values and this confirms that when rents are equal everywhere the demand for leisure can increase and the supply of labor decrease for households nearer the center, while once rents are endogenous the reverse must be true. For a household at a given location the elasticities of demand for goods and leisure and the elasticity of labor supply are calculated for all the parameters of the model. It is shown that the unavoidable costs of travel to work have strong effects on the rent gradient while the costs of the journey to shop have only weak effects, being offset by the variable frequency of shopping.     

Place-to-Place Rent Comparisons among Canadian Cities

This paper estimates average monthly gross rents for comparable rented private-sector accommodation in Census Metropolitan Areas across Canada. By “gross rent” is meant the typical monthly payment in a CMA for a principal residence by a tenant of given traits under the conditions of a standard lease to a for-profit landlord in competitive market equilibrium for premises used exclusively for accommodation, in an arm's length transaction, and includes heating and utility expenses where paid separately by the tenant. A single average gross rent is estimated for each city for dwellings and households, each with specified characteristics. This paper reviews the application of hedonic price models for this purpose, identifies shortcomings of current research in the field, and suggests a new form for such models. This new model is estimated using microlevel data from a sample of renter households taken across the twenty-three largest urban areas in Canada. A classical version of the model is fitted first to renter data for individual cities, and its limitations assessed. A measure of “relative supply” is introduced to help explain city to city variations in the hedonic prices. Then an all-city new model is estimated which incorporates relative supplies. This all-city model is then used to derive place-to-place rent comparisons.     

The second demographic transition, new household forms and the urban population of France during the 1990s

European household structures and their geography have been transformed in recent decades as a response to the interplay of demographic events and changing lifestyles. The formation of new households generally outstrips the rate of population increase, as more numerous and smaller households result from changing patterns of marriage, child-bearing, divorce and longevity. This paper tests some of the underlying hypotheses of the 'second demographic transition' using data from the most recent (1999) French population census. It provides an analysis of changing national household structures over the last quarter of the twentieth century and highlights the importance of smaller households, with particular emphasis on the rise of living alone. Trends identified in earlier work have intensified during the 1990s. In discussing the geography of new household forms, the paper focuses particularly on the evolution of major central cities and argues for more explicit links between their distinctive population and household structures and wider socio-economic change.

Dynamic Models in Space and Time

This paper presents a first‐order autoregressive distributed lag model in both space and time. It is shown that this model encompasses a wide series of simpler models frequently used in the analysis of space‐time data as well as models that better fit the data and have never been used before. A framework is developed to determine which model is the most likely candidate to study space‐time data. As an application, the relationship between the labor force participation rate and the unemployment rate is estimated using regional data of Germany, France, and the United Kingdom derived from Eurostat, 1983–1993.     

A HEDONIC MODEL OF INTERREGIONAL WAGES,RENTS, AND AMENITY VALUES*

ABSTRACT This paper develops a general multimarket hedonic model appropriate for a national, interregional study of wages, housing prices, and location-specific amenities. The model encompasses the effects of interregional location, intraurban location, and city size. Typically, hedonic studies focus on a single market such as labor or housing and ignore interactions implicit in a more global compensation mechanism. Examination of the comparative statics of our model indicates that single-market differentials are partial prices and are unreliable measures of amenity values in an interregional context. Unbiased amenity values are estimated for a comprehensive set of amenities using data on housing prices for 34,414 households and wages for 46,004 workers from the 1980 Census of Population and Housing. Statistically significant differences in housing prices and wages are found due to amenities.     

全球化视角下的世界城市网络理论

城市诞生时就相互保持着联系,只有将城市纳入世界城市网络中才能正确把握城市产生和发展的本质。1980年以来在第三次全球化浪潮的背景下,世界生产要素和产品市场开始整合,世界城市的兴起是国际劳动分工在空间上的表达。Cohen、Friedmann、Sassen、Castells和Taylor等学者提出并发展了世界城市理论,世界城市网络理论已经成为研究城市问题的重要框架。联系数据的缺乏长期制约了世界城市网络的实证研究,二十世纪九十年代中期以来学者们创新性地解决了方法论的问题,对世界城市网络的各个层面进行了实证研究。     

Folder 5, box 92

This short paper is concerned with a map of central Japan that the later University of Chicago Professor of Geography, Chauncy Harris, drew in September 1944, when he was assigned as an US Army Private to work at the headquarters of the Research and Analysis Branch, Office of Strategic Services. The map provided a functional classification of Central Japanese cities, highlighting those that specialized in manufacturing. It was precisely these set of cities that were targeted for firebombing by the US Airforce from March 1945.     

Labor Specialization, Transport Costs, and City Size

This paper proposes a simple model of pre-industrial urbanization. Agglomeration stems from increasing returns generated by the specialization of labor, whereas dispersion is provoked by the transport costs of the agricultural good. Considering the existence of some urban institutions (in particular guilds), the equilibrium size of cities is derived and it is efficient. Within this framework, the effects of urban domination (e.g., taxation of agriculture) and the emergence of primate cities are explored. Finally, the transition between early and modern urbanization is studied.     

From left-behind children to young migrants: the intergenerational social reproduction of rural migrant labor in China

ABSTRACT

Growing in number in the last two decades, rural migrant workers in China have completed intergenerational replacement, and young migrants have become a principal part of the migrant population. However, the process of such intergenerational reproduction has not been thoroughly examined. Based on field studies in the Chinese countryside, this paper analyzes the mechanisms of intergenerational reproduction of rural migrants from the perspective of rural communities, families, and school education. “Left-behind” rural communities, their migration-oriented social culture, and the cognition of rural–urban differences as constructed through migrant parents facilitated a subjective willingness for migration among left-behind children. Exclusion from urban-biased rural education is often the final external thrust for their migration. Having finished the transition, the households of a new young generation of rural migrants are experiencing a different crisis of reproduction. This paper argues that there is a systematic rupture between labor, households, and rural society and that this presents a critical development trap for China.     

Guests Who Stay

This paper presents a model of legal international labor migration, particularly temporary migration. It explores the likelihood of voluntary return of a majority of foreign workers to their home countries. The approach chosen is that of deterministic simulation. The results of the simulation suggest that a relatively quick labor turnover as required for a true guestworker system is unlikely under most conditions.
