This paper analyzes the political economy of environmental-policy formation in a trading economy with established rules for administered protection. We argue that the social costs associated with the adoption of an inefficient environmental regime are likely to be compounded by induced restrictions on trade when the effected industries are import competing. The preferences of interest groups for alternative environmental regimes tend to be linked to the legal-institutional setting in which trade policy is conducted. Under existing rules and practices in the area of administered protection, there is reason to believe that interest group preferences for an inefficient approach to pollution control will be strengthened because the adoption of such a regime is more likely to lead to a concomitant increase in trade barriers.  相似文献

Although his approach to politics and philosophy were relatively little known outside the United States, Leo Strauss was perhaps the most revered and the most controversial figure in post-war American political science. His followers today form what is arguably the most cohesive intellectual fraternity in the discipline. They constitute a highly influential opposition to the empirical-quantitative course taken by political science and political philosophy.
This study explores Strauss's ideas highlighting the unconventional mixture of substance and style that gives them an arrestingly idiosyncratic character. Substantively, Strauss belonged to the pre-modern intellectual tradition that understood Truth as accessible and knowable through philosophical contemplation. The form of his argumentation, however, his relentless critique of modernity and the moderns, is conducted with all the cognitive weaponry provided for by the modernist intellectual style.  相似文献

Abstract: Hydro-Québec's energy exports to neighbouring American electric utilities have increased substantially over the last decade as a result of conditions created by the oil crisis of the seventies. These increases have mostly been in the form of interruptible energy exchanges. Considering prices and costs of production on both sides of the border, the prospects for further growth of firm energy exports to the United States appear to be reasonably good. Some institutional features of electricity production in Quebec may raise concerns about fair trading. These concerns have little foundation, however, when consideration is given to the size of energy imports relative to the American northeast market, the pricing method of Hydro-Québec electricity exports to the United States, and the role played by the National Energy Board in Canada. Sommaire: Les conditions créées par la crise pétrolière des années soixante-dix ont permis à Hydro-Québec d'accroître de façon significative ses exportations aux services d'électricité américains. Cette croissance a pris la forme, en grande partie, de ventes d'énergie interruptible. Compte tenu des prix et des coûts de production actuels de chaque côdé la frontière, il serait raisonnable de s'attendre à une croissance des exportations d'énergie ferme aux États-Unis. Quelques caractéristiques institutionnelles de la production de l'électricité au Québec pourraient par contre soulever des inquiétudes quant au commerce équitable. Toutefois, ces inquiétudes apparaissent avoir peu de fondements quand on tient compte de la taille relative de ces exportations vers le marché de la Nouvelle-Angleterre, de la méthode tarifaire employée par Hydro-Québec pour ses exportations américaines et du rôle joué par l'Office national de léenergie du Canada.  相似文献

The general objective of this paper is to propose the establishment of a federal cost-sharing policy for reducing risk in transferring technology from the R&D stage to commercialization. Minimization of this risk barrier is expected to encourage diverse groups to participate in technology transfer. Section II focuses on specific barriers that impede technology transfer efforts and it presents policy options to minimize identified barriers. Section III introduces objectives of cost-sharing experiments from which cost-sharing policies can be formulated. In addition, we also identify specific cost-sharing participation criteria and success variables for the policy.  相似文献

A comprehensive list of innovations in the semiconductor industry during 1970 to 1980 was derived. The patterns of innovation across eight organizations showed consistency between the stages of initiation, adoption and implementation. Smaller organizations compared to large implemented a lower percentage of the innovations they initiated. The value of organization net sales and the dollar amount of the R&D budget, but not the number of organization of R&D personnel were significantly related to the number of innovations.  相似文献

The problems of adjustment during the midadolescent years were examined in 1298 privileged and underprivileged adolescents from the Sydney Metropolitan Area, Australia. Girls reported more problems than boys in all areas of adjustment and underprivileged adolescents more problems than the privileged group; however, a significant interaction effect was also found. Whether high-income or low-income group, the overwhelming number of problems were associated with educational adjustment and were interpreted as the reaction to pressures to achieve imposed on adolescents of this age.Received her M.A. (Hons.) and Ph.D. from Macquarie University.

We consider a new solution set for majority voting tournaments recently proposed by Banks (1985), and we examine its internal structure. In particular, we demonstrate that, in the absence of a Condorcet winner, there is always a cycle including precisely the points in the Banks set. We introduce the concept of “external stability” in order to facilitate analysis.  相似文献
