Cristina Puentes-Markides 《Futures》1995,27(9-10):1067-1075
The Pan American Health Organization (PAHO), Regional Office of the World Health Organization, is a United Nations agency specializing in providing technical cooperation in health to the countries of Latin America and the Caribbean. A futures approach has much to offer in this endeavour, and PAHO is making health futures tools available to its Member States through a variety of activities. The purpose of promoting futures thinking and the application of futures tools is to improve health-policy planning and public health action within the framework of the ‘Health for All’ vision and PAHO's current Strategic and Programmatic Orientations.  相似文献

The number of firms using alliances as part of their corporate venturing or market entry strategies has surged over the past decade. Three common reasons cited for pursuing alliances are technology convergence, market access and alliance partners' complementary resources. This paper contrasts the alliance strategies of HP and IBM, two major competitors in electronic services (i.e. Internet-based 'e- service') businesses, using the Familiarity Matrix as a display tool to portray the strategies. Whereas the HP strategy is to attempt to establish its technology infrastructure as the standard e-services infrastructure on the Internet, IBM aims to position its IBM Global Services, rather than its technology, at the center of this ecosystem.  相似文献

Water and Economic Growth   总被引:1,自引:0,他引:1  
Several hydrological studies forecast a global problem of water scarcity. This raises the question as to whether increasing water scarcity may impose constraints on the growth of countries. The influence of water utilisation on economic growth is depicted through a growth model that includes this congestible nonexcludable good as a productive input for private producers. Growth is negatively affected by the government's appropriation of output to supply water but positively influenced by the contribution of increased water use to capital productivity, leading to an inverted-U relationship between economic growth and the rate of water utilisation. Cross-country estimations confirm this relationship and suggest that for most economies current rates of fresh water utilisation are not yet constraining growth. However, for a handful of countries, moderate or extreme water scarcity may adversely affect economic growth. Nevertheless, even for water-scarce countries, there appears to be little evidence that there are severe diminishing returns to allocating more output to provide water, thus resulting in falling income per capita. These results suggest caution over the claims of some hydrological-based studies of a widespread global 'water crisis'.  相似文献

This paper focuses on the development of a theoretical scheme describing the transformation of primary incomes into end consumption and savings in the Russian economy. This scheme is basically a system of interrelated tables reflecting the distribution of primary incomes across the institutional sectors and their further reallocation and use. The scheme makes allowances for the specific features of the Russian economy and existing statistics. In terms of methodology, it is coordinated with the interindustry balance in current buyer prices and, from the theoretical standpoint, describes the connection between Quadrant II and Quadrant III of the balance. Therefore, the proposed system of tables is treated in the paper as Quadrant IV of the interindustry balance. The theoretical scheme is used by the authors as a necessary basis for constructing an empirical model of the relationship between value added and end product, which will be published in the next issue of this journal.  相似文献

Analysis of firm investment behavior during 1982–1993 shows that the Tax Reform Act of 1986 (TRA 86) Public Law No. 99-514 substantially affects both purchases and leases of depreciable assets. The changes in the regular corporate income tax rules are shown to lower asset acquisition. The effect of the alternative minimum tax (AMT) is found to vary with the debt share in firms’ capital structure and with the frequency of AMT exposure during the life of the assets acquired. On average, TRA86 depresses asset purchases less for firms that are subject to the AMT: AMT somewhat mitigates the negative effects of the regular tax rules.  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

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
