ABSTRACT We investigate how cross‐country differences in firms' fixed set‐up costs affect the trade‐off between global efficiency and spatial equity. Our analysis reveals that the standard assumption of symmetry in set‐up costs masks the existence of an interesting effect: the range of available varieties depends on the spatial distribution of firms. In such a setting, where the market outcome leads to excessive agglomeration in the symmetric case, a planner may opt for asymmetric set‐up costs and even more agglomeration. We show that the planner will always favor lower set‐up costs in the large country with more agglomeration when the consumer's marginal preference for variety is high, or with less agglomeration when the consumer's marginal preference for variety is low.  相似文献

This study examined the longitudinal spatial diffusion of state government policies and their related implementation organizations in the American states. The impact of coercive, institutional, and competitive processes on policy and state agency adoption were considered, as well as how aspects of the underlying policy can impact the degree of spatial diffusion. The rises of 27 different policy populations were analyzed over time, each representing not only a different policy form but a distinct implementation organization.
The policy adoption/spatial diffusion relationship across all populations was examined and results showed that the degree of spatial diffusion varied greatly. Analysis of potential relationship moderators indicated that federal impetus (coercive processes) led to an absence of spatial diffusion. Policies with an institutional basis also showed an absence of spatial diffusion while competition-based policies diffused spatially.  相似文献

This introduction to the special issue ‘Slavery, Servitude and Freedom in the Danish-Norwegian West Indies, 1672–1848’, edited by Niklas Thode Jensen and Vibe Maria Martens, situates the five essays in the issue in the framework provided by previous research. It begins with a historiographical overview of research carried out since c. 1950 concerning Caribbean and Danish-Norwegian West Indian racial slavery, and continues to locate the essays within this field and its recent historiographical trends. The introduction ends with a brief overview of the history of the Danish-Norwegian and later the Danish West Indies to provide the general context for the five essays.  相似文献

Immer größer wird der Einfluß der EU auf alle Lebensbereiche. Kaum ein Gesetz kann verabschiedet werden, ohne zuvor mit den Richtlinien europäischer Politik abgestimmt zu werden. In großem Maße betrifft dies auch den Umweltbereich. Als Mittler zwischen den Mitgliedsländern und der Kommission setzt die EU verstärkt auf thematisch spezialisierte Agenturen. UTE C. BAUER sprach mit DIPL.-GEOGRAPH STEFAN JENSEN , der seit zwei Jahren als Projektmanager bei der Europäischen Umweltagentur in Kopenhagen tätig ist.  相似文献

Abstract. The point of departure of this article is a conception of nations as discursive constructions of ‘us’/‘here’ in relation to ‘them’/‘there’. The empirical analysis examines three national discourses in Rehoboth, Namibia: (1) a discourse on the ethnic Baster nation; (2) a discourse on the Namibian nation‐state and (3) a discourse on the nation‐state containing a variety of ethnic nations (‘the rainbow nation’). The first discourse is characterised by a primordial belief about Rehoboth Basters, their homeland and their ties to this homeland. This conception is challenged by the discourse on the Namibian nation‐state. Here, it is argued that ‘ethnic nations’ are the creation of colonialism; with Namibia's new independence, it is seen as necessary to tear down previous ‘ethnic nations’ and build up a new, united nation‐state. The rainbow discourse attempts to integrate the other two discourses through ideas about overlapping nations, where the boundaries that separate ‘us’/‘here’ from ‘them’/‘there’ overlap and are inclusive rather than exclusive.  相似文献
