This paper attempts to identify the underlying principles of aid allocation, and particularly the balance of motivations as between the needs of recipient countries and the interests of donor countries. Two alternative models are fitted by cross-country regressions to bilateral and multilateral aid flows to some 80 developing countries in 1969–1970 and 1978–1980. The first (recipient need) model assumes that all aid is given to compensate for shortfalls in domestic resources. This model provides a reasonable explanation for the distribution of multilateral aid, but it is clearly not applicable for bilateral aid flows. The second (donor interest) model assumes that all aid serves only donor interests, defined to cover political/security investment and trade interests. This model gives generally good explanations of bilateral aid, but is a poor fit for multilateral aid. The relative importance of the various donor interests differs sharply among donors. The paper ends with an analysis of the shift in the balance of aid over the 1970s towards the recipient need element, and with a reference to the sharp change in policy in the 1980s towards increasing emphasis on donor interest aid.  相似文献

Life cycle theories suggest that businesses evolve through a number of stages: from an embryonic stage of introduction to growth, maturity, and decline. The force that propels their development is consumer acceptance. Industries pass through life cycles as well. However, not all industries pass through each stage of the life cycle, and the duration of stages varies across industries. Some industries skip the slow introductory phase; others avoid the decline stage and are continually revitalised through technological innovation. Still others continue to show substantial promise, but fail to take-off. It is this industry condition, persistent promise without corresponding growth, that we characterise as extended gestation. We believe that energy efficiency and renewable energy (EERE) businesses in Minnesota face the challenge of extended gestation. In this paper, we review the literature on the traditional stages of industry development, explore some of the factors that may lead an industry to remain in a state of extended gestation, and report the results of a study undertaken to better understand the factors that affect the growth of EERE businesses.  相似文献

A stochastic model is developed to estimate the expected social costs with and without a family planning program provided to a population. By examining the tradeoffs between the program costs and the costs of unwanted pregnancies, it is possible to estimate the costs and benefits of alternative family planning programs. Several extensions of the basic model are presented which permit the selection of optimal treatment variables for administration of a particular program as well as determining the long range effects of a particular family planning program.  相似文献

Scholars of urbanism have long been critical of America’s post-World War II efforts at urban renewal. What is generally less well understood is the theoretical context out of which urban renewal policy arose. This analysis sets forth the key precepts of modernist thinking in city planning as the explanation for urban renewal’s policy miscalculations. Data for Buffalo document the case, with emphasis upon the exclusion of blacks in the redevelopment process. Following three decades of failure, 1950 to 1980, a neighborhoodbased renewal project is now showing promise in meeting the housing needs of inner-city black households.  相似文献
