Technical networks (transport, telecommunications, energy etc.) possess paradoxical virtues. They produce ‘structuring effects’ on space, obtaining comparative advantages for the places they serve. But they are ubiquitous factors which also enable a homogenization of space. The myths of deterritorialization and dual space are refuted by empirical analyses of the interaction between networks and territories. Networks ‘format’ market areas and political territories. They create matrixes which until now were controlled by the public powers. Linked to current transformations – globalization, deregulation – the present mode of development of the technical macro‐systems brings about a telescoping of geographical scales which is having an adverse effect on the historic compromise between networks and territories. The boundaries of traditional political space have become obsolete and an economic rationale in the form of an extension of the technical networks predominates. In order to rediscover their policy‐making capacity, local authorities must pay more attention to controlling the occupation of public space as well as to the design and organization of the networks’ hubs. They should encourage the emergence of users as players in the regulation of public utilities so that debates on universal service and territorial equality may be activated. Les réseaux techniques (transport, télécommunication, énergie etc.) sont parés de vertus paradoxales. Ils produiraient des ‘effets structurants’ sur l’espace, procurant des avantages comparatifs aux lieux desservis. Mais, facteurs d’ubiquité, ils permettraient aussi une homogénéisation de l’espace. Ces mythes de la déterritorialisation et de la dualisation de l’espace sont réfutés par les analyses empiriques des interactions entre réseaux et territoires. Les réseaux ‘formatent’ des aires de marché et des territoires politiques; ils fabriquent des métriques, dont les pouvoirs publics avaient jusquà présent la maîtrise. Liées aux transformations en cours – globalisation, dérégulation – le mode de développement actuel des macro‐systèmes techniques entraîne un télescopage des échelles géographiques qui met à mal le compromis historique entre réseaux et territoires. Il y a obsolescence des frontières des espaces politiques traditionnels et prédominance de la logique économique dans l’extension des réseaux techniques. Afin de retrouver des capacités d’action, les collectivités locales doivent porter plus d’attention au contrôle de l’occupation de l’espace public ainsi qu’à la conception et à l’organisation des noeuds de réseau. Elles ont aussi à favoriser l’émergence des usagers comme acteurs de la régulation des services en réseau, afin que soient activés les débats sur le service universel et sur l’équité territoriale.  相似文献

We test the pecking order model of capital structure by examining the financing of firms that went public in 1983. We estimate a logit to predict external financing, and a multinomial logit to predict the type of financing using data on the IPO firms' security offerings during 1984–1992. Our results indicate that the probability of obtaining external funds is unrelated to the shortfall in internally generated funds, although firms with cash surpluses avoid external financing. Firms that access the capital markets do not follow the pecking order when choosing the type of security to offer.  相似文献

In the present paper, we propose an extension of Spengler's (1950) analysis of successive oligopolies, to study the effects of entry in the downstream and upstream markets. Free entry is analyzed using replica economies à la Debreu and Scarf (1963) . We find that free entry may have different effects in the upstream and in the downstream market. Namely, the usual convergence of the price to the corresponding marginal cost only occurs in the downstream market.  相似文献

DOES SAMPLE DESIGN MATTER FOR POVERTY RATE COMPARISONS?   总被引:1,自引:1,他引:0  
Poverty comparisons—an increasingly important starting-point for welfare policy analysis-are almost always based on household surveys. Therefore they require that one be able to distinguish underlying differences in the populations being compared from sampling variation: standard errors must be calculated. This has typically been done assuming that the household surveys are simple random samples. However, household surveys are more complex than this. We show that taking into account sampling design has a major effect on estimated standard errors for well-known poverty measures. In our samples they increase by around one-half. We also show that making only a partial correction for sample design (taking into account clustering, but not stratification, whether explicit or implicit) can be as misleading as not taking any account of sampling design at all.  相似文献

This study addresses the cost efficiency, economies of scale and scope of the Taiwanese banking industry, specifically focusing on how bank mergers affect cost efficiency. Adopting stochastic frontier analysis, we employ a translog cost function for efficiency estimation. Composite error terms are used to account for managerial inefficiency and environmental effects. Empirical results suggest that economies of scale and scope exist at small and medium-sized banks. Meanwhile, government-owned or -controlled banks are the most cost efficient. Non-performing loans increase the inefficiency of the banking sector by just under 10 per cent. Further analysis reveals that bank merger activity is positively related to cost efficiency. Mergers can enhance cost efficiency, even though the number of bank employees does not decline. The banks involved in mergers are generally small and were established after the banking sector was deregulated.  相似文献

Abstract: This paper studies the emergence of developing countries from a development trap. It shows that countries whose dynamics exhibits several growth peaks can be considered as cases of equilibrium jump. Applying this criterion to a sample of 65 countries that were initially very poor in 1950, it identifies 13 such countries, called ‘emerging economies’. Comparing emerging and non‐emerging economies in the 1950s and early 1960s, it shows that economic take‐offs starting in the 1960s can be related to health and education in the early 1950s, while other possible factors, such as savings, openness and democracy are not significant.  相似文献
