SPATIAL MOBILITY AND COMMUTING: THE CASE OF TWO‐EARNER HOUSEHOLDS*

ABSTRACT We examine the effects of the spatial configuration of workers' residence and workplace location on intraregional residential and job moving decisions of workers belonging to two‐earner households. We hypothesize that two‐earner households' residential mobility depends positively on the commuting distance of both spouses, but negatively on the distance between workplaces. Further, we hypothesize that workers' job mobility depends positively on the worker's commuting distance, negatively on the spouse's commuting distance, and positively on the distance between workplaces. Using data for Denmark, it appears that these hypotheses hold, and that the effects of the spatial configuration are rather large.     

TRANSPORT-RELATED FRINGE BENEFITS: IMPLICATIONS FOR MOVING AND THE JOURNEY TO WORK

ABSTRACT.  Firms offer compensation not only through wages, but also offer transport-related fringe benefits such as transport benefits (company cars, travel, and parking benefits) and relocation benefits to job applicants. We argue that these benefits are not randomly offered to employees, but depend on the job applicants' commuting costs. The firms' choice between these benefits affects the workers' incentive to move their residence closer to the workplace. Using information on firms' recruitment behavior in the United Kingdom, this paper shows empirically that the applicants' journey-to-work time induces firms to offer these benefits to job applicants. The implications of transport-related fringe benefits for commuting and relocation are found to be rather distinct. Transport benefits make employees less sensitive to the costs of commuting, whereas relocation benefits induce employees to move closer to the workplace.     

THE JOURNEY-TO-WORK DISTANCE IN RELATION TO THE SOCIO-ECONOMIC CHARACTERISTICS OF WORKERS

The aim of this paper has been to explore the variation in the distance between the residence and work locations of industrial workers. This distance has been theoretically and empirically related to the income, number of dependents, marital status, sex, and age of workers whose job site was located in the centre of the city. A multiple regression model has shown the over-all importance of the budget constraint as a factor in the residential location decision relative to the job site. Of the variables included in the analysis, the wage rate of the worker is the strongest determinant of the location decision. Although workers who have the same budget constraint show weak locational relationships with the job site relative to the number of dependents and marital status, as suggested by the model, the only strong difference in spatial location occurs when the budget constraint is allowed to vary. Once workers have the means to increase their over-all utility level, they do trade off journey-to-work disutilities for residential facilities farther from the central city job site. But the social conditions of the worker tend to influence the residence-to-work distance only slightly when considered apart from the influence they may have on the wage rate. The over-all dependence of the journey-to-work distance on these variables in this setting hence was small, reaching an R value of only 0.38.     

Spatial Moving Behavior of Two-Earner Households

Economic theory suggests that job choice, residential choice and commuting behavior are simultaneously determined. The case of two-earner households deserves special attention because the two wage earners share a dwelling but have different workplaces. We base our analysis of spatial moving behavior on search theory. We demonstrate that job mobility depends positively on the distance between the workplaces of the two wage earners. Residential mobility seems to be negatively influenced by the distance between the workplaces of the two wage earners. The search model also indicates that two-earner households will, on average, move less often than single wage earners.     

Racial rent differences in U.S. housing markets: Evidence from the housing voucher program

This paper exploits an unusually rich data set to estimate racial differences in the rents paid for identical housing in the same neighborhood in U.S. housing markets and to show how they vary with neighborhood racial composition. Results suggest that black households pay more for identical housing in identical neighborhoods than their white counterparts and that this rent gap increases with the fraction of the neighborhood white. In neighborhoods with the smallest fraction white, the premium is about 0.6%. In neighborhoods with the largest fraction white, it is about 2.4%. This pattern holds across different types of areas.     

COMPENSATION FOR COMMUTES IN THE LAND AND LABOR MARKETS: SOME EVIDENCE FROM THE TOKYO METROPOLITAN AREA*

ABSTRACT. Recent research suggests that in nonmonocentric cities compensation for commutes takes the form of both lower housing prices and higher wages. This paper develops a random utility model that predicts the probability of an actor choosing to commute between each residence and job in a metropolitan area conditional on the observed location of housing units and job sites. The model allows commuting time, origin-specific amenities, land prices, destination-specific amenities and wages to influence actors' choices. We estimate the model using maximum likelihood and generalized least squares techniques and data on commuting between each of 38 origin and 15 destination jurisdictions in the Tokyo metropolitan area. The empirical results show that, all else equal, a one percent increase in commuting time reduces the probability that a route (origin-destination combination) will be chosen by almost five percent. Origin-specific amenities are not completely capitalized into land prices and destination-specific amenities are not completely capitalized into wages. Desirable residential amenities include school quality and a low ratio of day to night population. Desirable workplace amenities include a large share of white collar jobs and a high density of employment.     

WELCOME TO THE NEIGHBORHOOD: HOW CAN REGIONAL SCIENCE CONTRIBUTE TO THE STUDY OF NEIGHBORHOODS?*

ABSTRACT We argue in this paper that neighborhoods are highly relevant for the types of issues at the heart of regional science. First, residential and economic activity takes place in particular locations, and particular neighborhoods. Many attributes of those neighborhood environments matter for this activity, from the physical amenities, to the quality of the public and private services received. Second, those neighborhoods vary in their placement in the larger region and this broader arrangement of neighborhoods is particularly important for location choices, commuting behavior and travel patterns. Third, sorting across these neighborhoods by race and income may well matter for educational and labor market outcomes, important components of a region's overall economic activity. For each of these areas we suggest a series of unanswered questions that would benefit from more attention. Focused on neighborhood characteristics themselves, there are important gaps in our understanding of how neighborhoods change – the causes and the consequences. In terms of the overall pattern of neighborhoods and resulting commuting patterns, this connects directly to current concerns about environmental sustainability and there is much need for research relevant to policy makers. And in terms of segregation and sorting across neighborhoods, work is needed on better spatial measures. In addition, housing market causes and consequences for local economic activity are under researched. We expand on each of these, finishing with some suggestions on how newly available data, with improved spatial identifiers, may enable regional scientists to answer some of these research questions.

快速工业化城市职住空间平衡与过剩通勤研究——以中山为例

过剩通勤是衡量城市居民职住空间组织和通勤效率的重要指标。本文以快速工业化城市中山市为例,采用2012年中山市交通调查数据,分析中山市职住空间平衡与过剩通勤状况。通过线性规划模型计算发现,中山市居民的通勤距离、过剩通勤率(E)、通勤容量(C_u)使用率均普遍小于国内大城市和西方城市。城市空间结构与土地利用、产业结构与就业结构对中山市的通勤特征的形成有重要的影响。过剩通勤各项指标与户籍、职业类型和家庭收入有显著的相关性。表现为家庭收入越高,过剩通勤率相对较高。机关事业单位和企业行政办公人员通勤效率较低,而产业工人通勤效率较高。非本市户籍人口通勤效率高于本市户籍人口。     

基于地铁刷卡数据的城市通勤与就业中心吸引范围研究

地理时空大数据为通勤行为和城市空间结构研究带来了新的机遇。基于一周地铁刷卡数据,采用出行链（trip-chain）数据模型对用户一天的出行进行描述,建立通勤识别规则,识别出上海市域的职住空间和通勤格局。上海市域平均通勤时间为35 分钟,通勤主流向是向心流,说明上海市域依旧表现出强单中心结构。市域就业单中心与居住郊区化并存,中心城区多核心就业已经形成。在此基础上进一步分析中心城区13 个就业（次）中心的吸引范围、模式以及在整个市域的影响力,讨论多中心发展对职住平衡与通勤消减的意义。结果表明：多中心发展有利于城市通勤的合理分配,虽然次中心的平均通勤时间不一定减少,但是就业（次）中心已经表现出对邻近地区的通勤吸引和对主中心的通勤分流。     

Influence of Race on Household Residential Utility

Residential location choice models are an important tool employed by urban geographers, planners, and transportation engineers for understanding household residential location behavior and for predicting future residential location activity. Racial segregation and residential racial preferences have been studied extensively using a variety of analysis techniques in social science research, but racial preferences have generally not been adequately incorporated into residential location choice models. This research develops residential location choice model specifications with a variety of alternative methods of addressing racial preferences in residential location decisions. The research tests whether social class, family structure, and in‐group racial preferences are sufficient to explain household sensitivity to neighborhood racial composition. The importance of the interaction between the proportion of in‐group race neighbors and other‐race neighbors is also evaluated. Models for the San Francisco Bay metropolitan area are estimated and evidence of significant avoidance behavior by households of all races is found. The results suggest that social class differences, family structure differences, and in‐group racial preferences alone are not sufficient to explain household residential racial preference and that households of all races practice racial avoidance behavior. Particularly pronounced avoidance of black neighbors by Asian households, Hispanic neighbors by black households, and Asian neighbors by white households are found. Evidence of a decrease in household racial avoidance intensity in neighborhoods with large numbers of own‐race neighbors is also found.     

基于健康视角的城市就业者通勤模式选择及影响因素研究——以南京市为例

中国城市出现的居住和就业"空间不匹配"现象,对就业者日常通勤时间和方式产生了重要影响,进而影响就业者健康状况。依托南京市居民身体活动和健康状况问卷调查数据,根据不同通勤方式身体活动量的大小将就业者的通勤模式分为积极通勤、公共交通通勤和机动车通勤三种,构建多项Logistic回归模型探究城市就业者通勤模式的选择及相关影响因素。结果表明:(1)就业者对自身健康的主观认知和客观身体健康状况以及是否散步等健康行为显著影响通勤模式的选择;(2)通勤时间、加班等与工作相关的变量与就业者机动车通勤显著正相关,雨雪天气与积极通勤显著负相关;(3)个体社会经济属性中性别、年龄、家庭人口规模以及是否拥有小汽车等显著影响通勤模式选择。基于研究结果,本文对如何引导就业者选择更加积极和可持续的通勤模式提出了政策建议。     

Pottery Use-Alteration as an Indicator of Socioeconomic Status: An Ethnoarchaeological Study of the Gamo of Ethiopia

The use of a pottery vessel leaves markers on the ceramic wall that can inform archaeologists how the vessel functioned in the past. At present, archaeologists have little information for understanding how use-alteration reflects the complex nature of ceramic function and socioeconomic status. I conducted a 2-year ethnoarchaeological research project among the Gamo people of southwestern Ethiopia, who continue to produce and use pottery on a daily basis. This research indicates that interior surface attrition occurs primarily on pottery vessels used in wealthy households because of fermentation processes from high-status foods. Thus, the Gamo example suggests that there is a relationship between ceramic use-alteration and household socioeconomic status.     

Location choice,life cycle and amenities

Our study proposes a housing location choice model where a household faces a trade‐off between proximity to place of employment and proximity to amenities. We consider subsamples of high amenity cities and low amenity cities and households with and without children. We show that the roles of gender, education, homeownership, household composition, and public transportation vary significantly depending on level of amenities. Households with a female head of household, those with a working spouse and with older children prefer locating closer to downtown amenities. Female workers with and without children locate closer to work, in high and low amenity cities.     

基于手机数据的北京城市女性职住关系研究

自20世纪70年代以来，女性地理学的研究成为城市地理学关注的热点。本文基于2015年12月1日工作日涵盖所有交通出行方式的手机数据，采用核密度分析、回转半径、网络分析等方法，分别从市域、中心城区、就业集聚区三个空间尺度分析北京城市女性职住关系特征。研究发现：尺度影响女性职住关系特征，大尺度空间范围内的女性职住关系特征不显著；与工作在中心城区的女性相比，郊区女性的职住地联系较紧密；公共服务设施较为完善且以服务业为主导的工作地对女性就业者的吸引力更大。从工作地的角度探究女性职住关系特征，丰富了城市社会地理学和女性主义地理学的研究视角，其研究结果为人性化城市空间建构和设施配置提供理论依据。     

Seventeenth-Century Glass Trade Beads from La Salle's Fort St. Louis and the Grand Village of the Kaskaskia

Abstract

Glass trade beads are described here from two seventeenth-century sites located in the upper Illinois Valley, La Salle's 1682–1691 Fort St. Louis and the nearby Grand Village of the Kaskaskia, destroyed during an Iroquois raid in 1680. Simple monochrome drawn beads characterize both bead assemblages and each contains significant percentages of very small (<2 mm) and small (2–4 mm) size beads. Dominant colors are blue, white, and black. Turquoise-blue beads were a staple of the French trade at this time in the Illinois Country, particularly in transactions involving La Salle and his successors based at Fort St. Louis. Comparative treatment provided as part of this research indicates that there are significant similarities between the bead assemblage from Fort St. Louis and the beads recovered from the 1686 wreck of La Salle's ship Belle in Matagorda Bay off the Texas coast.     

THE IMPACT OF MIXED LAND USE ON RESIDENTIAL PROPERTY VALUES*

ABSTRACT Contemporary European urban planning policies aim to mix land uses in compact neighborhoods. It is presumed that mixing land uses yields socioeconomic benefits and therefore has a positive effect on housing values. In this paper, we investigate the impact of mixed land use on housing values using semiparametric estimation techniques. We demonstrate that a diverse neighborhood is positively valued by households. There are various land use types that have a positive impact on house prices, e.g., business services and leisure. Land uses that are incompatible with residential land use are, among others, manufacturing and wholesale. It appears that households are willing to pay about 2.5 percent more for a house in a mixed neighborhood. We also show that there is substantial heterogeneity in willingness to pay for mixed land use. For example, only apartment occupiers are willing to pay for an increase in diversity, whereas households living in other house types are not willing to pay for diversity.     

海口城市建成环境对高峰期网约车通勤出行的影响——基于滴滴出行数据

网约车的普及重塑了居民的通勤行为。城市建成环境作为居民通勤出行的制约因素,是交通地理学的重要研究议题。采用海口市滴滴出行订单数据,刻画格网尺度的居民通勤时间与通勤距离的空间分异格局,并运用地理探测器分析城市建成环境对居民通勤出行的影响。结果表明：(1)早晚高峰通勤时间在空间上表现为中间集聚、四周分散的分布特征;早晚高峰通勤距离呈现梯度递增的圈层结构。(2)不同维度的建成环境因素对通勤时间和通勤距离的影响程度不一;其中距公交站距离、距市中心距离、职住比、道路邻近度是核心影响因素;人口密度、就业可达性、路网密度产生较为显著的影响。(3)从影响效应看,交通区位优越、职住趋于平衡、道路邻近度高、就业可达性好能引导网约车与多元交通协同发展。结果可为改善交通出行环境、优化居民通勤结构提供借鉴。     

The Diurnal Cycle of Regional Commuter Systems: North Wales, 1991

Places of household residence and places of commuter destination are considered in a contiguous system of subareas constituting a region. An intrahousehold distribution of household members, by subarea of their commuting destination, is considered for each subarea of residence. A household composition matrix is constructed in reference to the average number of commuters to subareas of destination, per household at a subarea of residence, across all subareas. The matrix is a linear transformation from the spatial distribution of households onto the spatial distribution of daytime population, over all subareas of the region. Diurnal population change throughout the region is rendered by this transformation. A linear optimization model extending this transformation formalizes general conditions that relate the diurnal population system to household choice of residence and work. Further, the division of the region into subareas is assumed to be such that the average household in each subarea contains at least one person who remains in the subarea during day and night. Under these conditions, the diurnal system is shown to be analogous to the Leontief input‐output model. An example of eleven counties of North Wales, along with an exogenous area of northwestern England, drawn from the 1991 census of the United Kingdom, illustrates the formal relationships.
