"The decreasing fertility rates in Sweden during the 1970s can be explained as postponement of childbearing. An increasingly larger part of each generation has chosen to bear children at a late age, after education and some years of occupational work. As a consequence, the yearly age-specific rates will, in years to come, change systematically towards relatively high rates for women in the second half of the fertile period; changes which are important in population projections. To predict the future rates a model based on birth order data and assumptions about the final family size is used. The model and its application in the 1989 projection of the Swedish population is discussed in the paper. Alternative projections and the assumptions behind the alternatives are specified."  相似文献

Aid, Agriculture and Poverty in Developing Countries   总被引:1,自引:0,他引:1  
The authors make two contributions to the debate on aid‐effectiveness, illustrating that for impact on poverty what matters is not just the level but also the composition and stability of aid. One specific implication of this for aid policy is that aid most effectively reduces poverty if it supports public (and other) expenditures which are supportive of agricultural development. Regression analysis confirms that these are not only direct expenditure on agriculture, but also on education and infrastructure, and military expenditure has a negative impact. Three factors appear to be particularly conducive to the development of stable pro‐poor expenditure patterns (and in particular pro‐agriculture expenditure patterns). These are expenditure strategies which protect the poor against risk, the development of stable relations between governments and aid donors, and long‐term political commitment to pro‐poor strategies by government. The argument is pursued partly by panel‐data econometric analysis of developing countries as a whole, and partly by case studies of sustained and non‐sustained green revolutions in heavily aid‐dependent countries in Africa.  相似文献

This paper was published in the wake of Pope John Paul II's encyclical 'Evangelicum Vitae', which condemns abortion and contraception. The author describes how, in the mid-1970's, the Vatican blocked the implementation of President Nixon's 'National Security Study Memorandum 200', which was intended to combat global overpopulation. The author explains that excessive population growth is considered threatening to U.S. security interests, and concludes that "papal security-survival along with the influence of fundamentalist Protestant opposition to birth control is now pitted against the U.S. and world security-survival."  相似文献
