Regional Labor Market Dynamics, Housing, and Migration

Abstract.  This study explores the impact of plant‐level labor market dynamics and housing markets on gross migration flows. The internal and the external reorganizations of regional labor markets are shown to be related. An increase in internal turnover of jobs and workers in regional labor markets is found to increase net‐migration. This effect arises mainly from a reduction in out‐migration. Housing markets constitute constraints for migration. In particular, an increase in regional housing prices and a large share of owner‐occupancy housing discourages net‐migration to a region by reducing in‐migration. In contrast, the out‐migration rate remains largely unaffected by housing markets.

以北京浩沙健身连锁俱乐部为例,尝试利用公众在大众点评网、新浪微博等网络社区中发布的关注度、评价等作为加权因子,分析连锁网点之间的竞争状态,建立了一个基于互联网信息的加权因子计算模型,计算各连锁店的市场竞争域,结果显示互联网空间信息能够对连锁店之间的空间竞争产生指示作用,各分店表现出明显的竞争力差异;提出对加权Voronoi图区位意义上的地理学新解释:它不仅反映连锁店基本市场域,而且其边线弯曲度和单元面积的变化还可折射各连锁店在互联网空间中的吸引力差异。     

Thinking Through Networks and Their Spatiality: A Critique of the US (Public) War on Terrorism and its Geographic Discourse

Conventional thinking about war is encumbered by an inappropriate geographic paradigm that conceptualizes "targets" in terms of fixed latitudinal/longitudinal locations. This paper reconceptualizes terms such as "war" and "targets" to recognize intangible problems and develop appropriate counter‐terrorist strategies. This requires geographic inquiry focused on spatiality, not on location. We frame our discussion about terrorist networks (Al‐Qaeda in particular) in terms of understanding a network's sense of place and sense of space . The former "places" a network's meeting and recruiting grounds; the latter clarifies the operational dynamics of a network across space, at different scales, from the body to the neighborhood, to the region, and across nations. We argue that the roots of terrorism lie in conditions of disenfranchisement in particular types of places, understanding, however, that the socio‐cultural fabric of a terrorist network such as Al‐Qaeda evolves across space as well as time. Counter‐terrorist strategies should target neither people nor places but rather the conditions that give rise to terrorism; further, "intelligence" should focus on network dynamics, beyond particular people in particular places. We draw from network theories (specifically actor network theory and network approaches in economic sociology) to unravel network dynamics, and we draw from the literature on spatiality to interpret such dynamics in space, over time. We advocate a non‐military engagement with terrorism on both moral and strategic grounds; here we focus on the strategic dimension, the value of which has received scant attention.     

携程旅行网旅游“新零售”空间格局及形成机制——以上海市线下门店为例

基于携程位于上海市的线下门店及相关POI 数据，运用 GIS 空间分析和地理探测器等方法，探讨携程旅游“新零售”空间格局、区位选址及形成机制。结果表明：①携程旅游“新零售”在发展初期，其区位选址仍具有向心性，但不如传统零售业对城市中心区位需求强烈，向中心城区边缘及城市近郊区域下沉趋势明显；②呈现集聚分布特征，形成“多中心-外扩”式分布模式；③区位选址依赖于以写字楼为主的线下生活服务场景，对商务办公区的偏好超越对商业中心的偏好。交通区位、传统旅行社分布、地租水平影响次之，CBD 趋近度、商圈等级影响较小；④携程线下门店空间格局及区位特征是企业业务板块规划、地理实体空间竞争、区域产业配套水平共同作用形成的结果。

The Terrible Geographicalness of Terrorism: Reflections of a Hazards Geographer

Oppositional engagement with the phenomenon of terrorism by geographers could bring much needed scholarly clarity and balance to the militaristic dominant discourse on terrorism. The hazards subfield within the discipline of geography is germane to research on terrorism, as hazards geographers have been deeply concerned with environmental and technological extremes threatening human life and well‐being. A hazards perspective on terrorism could contribute towards defining terrorism, clarifying the contours of the terrorism discourse, root causes, and response. Insights gleaned from geographical research on social violence, technological and environmental hazards can be eminently applicable to researching various aspects of terrorism. The fundamental point is that terrorism is a deeply geographical phenomenon with potentially disastrous consequences for international peace. Beyond enhancing human safety, the geographical research agenda in terrorism will be part of the struggle to wrest control of the terrorism terminology away from the Western politico‐military elites, to keep them from using it to whip their real or imagined enemies.     

Geographical Imaginations and Spaces of Political Engagement: Examples from the Indian Alliance

This paper is concerned with the various ways in which geographical imaginations are inflected in politics. It draws on examples from a three‐way partnership of civil society organisations based in Mumbai, India. This movement seeks to reconfigure the governance of anti‐poverty strategies by placing "poor people" at the centre of its activities. The partnership, which refers to itself as the Alliance , is involved in the mobilisation and creation of a range of alternative geographical imaginations that are inflected in the production of new spaces of political engagement. By exploring two of the Alliance's strategies—enumerations and exhibitions—I will illustrate some of the ways in which these alternative geographical imaginations feature in the creation of spaces of political engagement. These strategies involve the practical demonstration of the capacities of the poor to donors and states, and reflect a particular conception of the poor and social change.
The spaces of political engagement formed in part through the Alliance's work depend significantly on a commitment to non‐party alignment, an approach that has received criticism from NGOs and commentators involved with urban poverty. I will argue that the Alliance represents a broad development alternative—rather than a form of alternative development—which nonetheless is making substantial progress in the politics of citizenship in Mumbai.     

Spaces of Labor Activism, Mexican‐American Women and the Farm Worker Movement in South Texas Since 1966

This paper studies the farm worker unionization experience and the historical development of Mexican‐American women's activism in South Texas to elaborate more precisely the relationship among socio‐spatial practices, political activism and labor's geography. Drawing upon archival documents and interviews, the paper describes how Mexican‐American farm workers used public space for political activity; however, radical unionization efforts also domesticized other spaces for women's activities. The paper chronicles how Mexican‐American women in South Texas transformed the farm worker center from a "domesticated space" into one of empowerment. In short, women in the union made the farm worker center into a space that challenged both the class‐based structure of larger South Texas society and masculinist practices within the larger farm worker movement. The analysis advances the imperative to better understand how workers "make space" to ensure their own survival. The paper advances the study of labor geography by arguing that working class mobilization reconstitutes dynamic social geographies within laboring communities themselves. In arguing this point, the paper illustrates the limitations of activism based solely on the use of public space and argues for more attention to the significance of other socio‐political spaces for labor mobilization.     

A tetradic analysis of GIS and society using McLuhan's law of the media

The social implications of GIS have been debated over the past five years among scholars in several disciplines. GIS have been either conceived by practitioners as value‐free, neutral tools for problem‐solving or castigated by critical social theorists as socially biased technologies serving only corporate and state interests. Neither of these polarized views is very helpful in understanding the complex relationship between GIS and society. This paper argues that GIS are increasingly becoming media for communicating various crucial social and environmental information to the general public. By reconceptualizing GIS as media, the paper conducts a detailed tetradic analysis on the social implications of GIS using Marshall McLuhan's law of media. The analysis reveals the paradoxical and ambivalent nature of GIS technology. To make GIS fulfill democratic ideals in society, this paper calls for a shift of perspective, from viewing them as instruments for problem‐solving to viewing them as media for communication. This shift from instrumental to communicative rationality enables us to examine more critically and holistically how space, people and environment have been represented, manipulated and visualized in GIS and thus promotes a more critical and democratic GIS practice .     

'From Noodles to Satellites': The Changing Geography of the Japanese Sogo Shosha

The need for a less occidental approach to understanding organizational‐geographical change is increasingly accepted. However, there is a danger of replacing one stereotype with others drawn simplistically from alternative capitalisms. In this paper we use the Japanese general trading company ‐ the sogo shosha ‐ as an example. We show how their city-based, international networks evolved over a long period of time and, through a detailed case study of the sogo shosha in Europe, how their organization and behaviour need carefully to be interpreted.     

Optimal Timing and Location in Competitive Markets

The choice of a good location strategy is one of the most crucial decisions facing a retailer. While a number of recent articles have addressed the issue of site selection, the related issue of optimal timing and preemption has been largely ignored. In this paper, we present an integrated location allocation model that allows a retailer to formulate an overall location strategy by addressing the questions of how many stores to open, where to open them, and when to open them. In addition, the model explicitly incorporates demand growth scenarios and takes into account the dynamics of competitive actions. As an illustration of its use, the model is applied to a simple yet realistic decision scenario.     

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.     

MAPPING FINANCIAL LITERACY: COGNITION AND THE ENVIRONMENT

Recent research suggests that regions can be characterized according to their (more or less) financial literacy. One implication is that there may be regional ecologies of finance nested within national institutions and global markets. This article begins by situating behaviour in time and space, linking behaviour to the interaction between cognition and the environment. This is followed by a substantive account of the geographical scale of the “environment” working from the global to the local and in return from the local to the global. By implication, maps of financial literacy reflect the skills and expertise of resident populations, affecting how they sort amongst the relevant information to make effective decisions (which have a material effect on their long‐term welfare). Explaining how and why this is the case is one goal of the article. It is also acknowledged that representing the relationship between behaviour and the environment is conceptually and empirically challenging. Reference is made to new findings about the ways in which people “sample” the world around them, suggesting that cognition and the environment are intertwined in ways that may reinforce existing urban and regional inequalities. In conclusion, implications are drawn for the design and implementation of pension and retirement saving policies.

Accounting for Temporal Demand Variations in Retail Location Models

This article develops and calibrates a spatial interaction model (SIM) incorporating additional temporal characteristics of consumer demand for the U.K. grocery market. SIMs have been routinely used by the retail sector for location modeling and revenue prediction and have a good record of success, especially in the supermarket/hypermarket sector. However, greater planning controls and a more competitive trading environment in recent years has forced retailers to look to new markets. This has meant a greater focus on the convenience market which creates new challenges for retail location models. In this article, we present a custom built SIM for the grocery market in West Yorkshire incorporating trading and consumer data provided by a major U.K. retailer. We show that this model works well for supermarkets and hypermarkets but poorly for convenience stores. We then build a series of new demand layers taking into account the spatial distributions of demand at the time of day that consumers are likely to use grocery stores. These new demand layers include workplace populations, university student populations and secondary school children. When these demand layers are added to the models, we see a very promising increase in the accuracy of the revenue forecasts.     

Competitive Multifacility Location on Networks: the (r∣Xp)‐Medianoid Problem

Abstract.  We investigate the ( r ∣ X _p )‐medianoid problem for networks. This is a competitive location problem that consists of determining the locations of r facilities belonging to a firm in order to maximize its market share in a space where a competitor is already operating with p facilities. We consider six scenarios resulting from the combination of three customer choice rules (binary, partially binary, and proportional) with two types of services (essential and unessential).
Known discretization results about the existence of a solution for the set of nodes are extended. Some examples and computational experience using heuristic algorithms are presented.     

Prospecting for Economic Returns to Research: Adding Informational Value at the Market Fringe

Abstract.  Private markets constantly assess project investment opportunities across a spectrum of such possibilities. The market's perspective on the boundary of viable projects, however, may be more limited than socially optimal due to informational constraints. In the case of economic development projects in particular, this boundary could be extended by public researchers. This paper constructs a method to estimate the private and social value‐added of such research, providing a new means to understand and assess the public/private sector interface. The framework uses agents' evolving subjective perceptions through Bayesian updating to value research information, along with methods to estimate functional forms and relative optima. Two case studies of regional development research on value‐added agriculture in Colorado highlight the utility of the approach.     

TESTING THE NEW ECONOMIC GEOGRAPHY: MIGRATIONS AND INDUSTRIAL AGGLOMERATIONS IN SPAIN*

ABSTRACT This paper examines whether access to markets had a significant influence on migration choices of Spanish internal migrants in the interwar years. In it we perform a structural contrast of a New Economic Geography model that focuses on the forward linkage that links workers location choice with the geography of industrial production. The results prove the existence of a direct relation between workers' localization decisions and the market potential of the host regions. This could help to explain the apparently low intensity of internal migrations in Spain until the 1920s as well as its geography.     

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.
