In the presence of foreign factor ownership tariffs change not only the terms of (goods) trade but also income flows between countries. Assume that only the home country owns factors abroad. Then the optimal tariff is negative if and only if foreign factor ownership entails trade-pattern reversals. Trade-pattern reversals are neither a necessary nor a sufficient condition for a negative optimal tariff if the foreign country owns factors in the home country. Changes in the home country's tariff shift the foreign country's offer curve. This adds a new dimension to optimal tariff analysis.  相似文献

A bstract Previous theoretical and empirical research on economic sociology leaves much to be desired in terms of consistently defining the agenda and objectives of the discipline As a result, economic sociology often appears to lack a clearly defined mission and purpose This is epitomized by various failures to establish adequate epistemological relations of the proper realm of economic sociology with those of economics and sociology, and especially with the domain of rational choice theory This failure is compounded by a misplaced distinction between the subject matter of economic sociology and that of sociological economics, or socioeconomics And some recent works in the discipline (including the ambitious Handbook of Economic Sociology ) have not helped to remedy this situation In this paper, we try to address this situation by suggesting some reformulations of the subject matter of economic sociology in relation to those of related disciplines In addition, we attempt to redefine the field of the sociology of the market which is seen as the focal specialty of economic sociology  相似文献

The channel literature has paid little attention to issues related to exclusive dealing governance arrangements. Consequently, there is only limited knowledge about how exclusive dealing impacts various channel processes and outcomes. This gap is especially regrettable since exclusive dealing, in addition to being one of the most commonplace governance formats within the distribution channels, is also one of the best exemplars of viable unilateral governance formats. In this initial investigation, the authors explore the linkages among the constructs of exclusive dealing, relationalism, communication, and performance. Empirical data for the study were drawn from the photocopier industry. He obtained his M.B.A. and D.B.A. degrees from Boston University. His primary research interest includes channels of distribution, franchisor-franchisee relationships, and consumer purchase behavior in international contexts. He has published articles inJournal of Marketing Channels and the proceedings of several marketing conferences. This article was crafted when Rajiv Dant was at Boston University. He received his M.B.A. from Bombay University and his Ph.D. from Virginia Polytechnic Institute and State University. His research focuses on channels of distribution, with primary emphasis on franchise structure, franchisee-franchisor relationships, and public policy aspects of franchising growth and ownership topics. His research has been published inJournal of Marketing, Journal of Public Policy & Marketing, Research in Marketing, Journal of Retailing, Journal of Business Research, Journal of Business Venturing, Journal of the Operations Research Society, Marketing Letters, Journal of Small Business Management, Journal of Economic Psychology, Southern Business & Economics Journal, Philosophical and Radical Thought in Marketing, Journal of Healthcare Marketing, Journal of Marketing Channels, andInternational Small Business Journal.  相似文献

This study examines the influence of day-of-the-week patterns in security returns on long-run IPO underperformance. Comparisons are made between the IPOs in Ritter's [20] database, and a constructed set of matching firms based on SIC code and size, using NYSE, AMEX, and NASDAQ securities. It is found that virtually all of the IPO underperformance occurs on Mondays and Tuesdays and that the degree of underperformance significantly differs from other days. Thus, a common explanation may exist for the general day-of-the-week pattern in security returns and IPO long-run underperformance.  相似文献

本文研究了用于开关电容(SC)滤波器的离散积分器,所推荐的积分器是由无耗离散积分器(LDI)和双线性离散积分器的最佳线性结合而成,因此,称之为组合离散积分器(CDI)。由于这个积分器使正常转折频率增加一倍,并使高频离散积分器误差减少到最低限度,所以它对高频应用是理想的。文中给出了组合离散积分器的几种SC实现,并且还给出了以组合离散积分器为基础,模拟一般一阶和二阶的模拟滤波器单元的SC电路。  相似文献

The paper seeks to evaluate the evidence on the employment effectsof the collective working-time reductions in Europe over thepast 20 years. While theoretical analyses produce contradictoryassessments, most empirical studies show positive employmenteffects but take insufficient account of these conditions underwhich the reductions in working time were implemented. Theseconditions for the success of collective working-time reductionsinclude an active training policy designed to minimise skillshortages in the labour market, the modernisation of work organisation,wage increases in conjunction with productivity gains and amore equal income distribution.  相似文献

Summary Economic design of one-sided screening procedures for improving outgoing product quality based on a screening variable is considered for the case with all parameters unknown. It is assumed that the performance and screening variables are jointly normally distributed and that costs are incurred by screening inspection, acceptance of an imperfect item, and disposition of a rejected one. A method for finding optimal cutoff value based on the predictive distribution is presented.  相似文献
