The linkage between development and health is clearly spelt out in the definition of primary health care by the World Health Organisation. There is a widespread and growing disillusionment with the traditional Western approach to health care which fails to meet the real demands of the Third World situation.

This paper looks briefly at conditions in the developing world and the strategy proposed by the W H O to attempt to meet the objective of health for all by the year 2000 and refers to the South African situation.  相似文献

Summary In this article it is shown that Keynes concept of uncertainty is not identical with that of Knight, as is often argued. The identification of Keynesian with Knightian uncertainty has contributed to the neglect of an aspect of Keynesian uncertainty that is important in understanding the functioning of a monetary economy. Therefore, it is concluded that monetary theory can benefit from the development of an analytical apparatus that incorporates all aspects of Keynesian uncertainty.I am indebted to Mr. J. de Haan, Professor J.A. Kregel, Professor S.K. Kuipers, Professor J. Pen, Dr. J. Snippe and Mr. A. van Witteloostuijn for their comments on an earlier version of this paper. It goes without saying that they cannot be blamed for any remaining errors.  相似文献

Summary In 1961 Arrow, Chenery, Minhas and Solow presented their C.E.S. production function, which was based on the relation between the real wage rate and the average labour productivity. They argued that, if the aggregate production function is continuous, lineair and homogeneous, then, with perfect competition and profit maximalization prevailing, the relation between the real wage rate and the average labour productivity is reflection of the production structure. This relation can, therefore, be used for specifying the production structure.In the present paper, the same line of thought is applied to the Dutch economy. Several hypotheses on the relation between wage rate and average labour productivity are tested. Statistically, it turns out that in the Dutch economy the elasticity of substitution between capital and labour is not a constant: it declines with increasing capital-labour ratio. Two statistically acceptable production equations that have this feature are presented.The efficiency parameter appearing as an integration constant in both production equations shows a decline: with labour productivity constant, the capital-labour ratio is falling over time. This means that the relation between labour productivity and capital-labour ratio shifts over time. Another outcome of this study is that technical progress is capitalaugmenting and that it brings about 50 percent of the growth in the labour productivity.De schrijvers zijn dank verschuldigd aan Prof. Dr. F.

Summary Two behavioural models of economic growth are developed: a neo-classical and a neo-keynesian (Kaldorian) one.In the neo-classical model consumers aspire to a certain level of consumption. Savings and supply of labour (man-hours) are the means for reaching this level.In the neo-keynesian model firms and households have a certain aspiration level with respect to profits and consumption, respectively. To reach these levels firms decide to invest and households to supply man-hours.In both models growth is entirely dependent on the parameters of the behaviour equations. In this respect they differ from the traditional neo-classical and neo-keynesian (Kaldorian) models, in which growth is eventually determined by autonomous technical progress and growth of the labour force.  相似文献
