Country size and ‘insulation’ from external disturbances

Summary This paper considers the relationship between economic size and vulnerability to external disturbances. In order to analyze this issue effectively a model comprising three different-sized economies is constructed. The issue of economic size and insulation is approached from this alternative perspectives depending upon the relative size of (a) the `recipient' country and (b) the transmitting country. The results of the analysis indicate that, contrary to popular belief, a small country under floating exchange rates is less severely affected by external economic events than a large economy regardless of the type of external disturbance and the degree of domestic wage indexation.This paper has been improved by the helpful comments of a referee.

生态文化旅游的价值评价研究

旅游业已经成为现代经济增长一个新的亮点,特别是生态文化旅游的增长速度更是惊人,而其发展的价值平衡是生态学和经济学必须面对的一个难题。本文依据意大利经济学家帕累托的不均匀分布定律,运用埃奇渥斯盒状分析图,在某一选定的生态资源环境的承载量既定的基础上,从生态文化旅游的价值交换的角度考虑,并且从定性研究转向定量研究,分析研究生态文化旅游的价值帕累托最优曲线,用以筛选生态文化旅游的工程项目。     

De produktiestructuur van Nederland in de periode 1950-1966

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.

Gedragsmodellen van de Economische Groei

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.     

Half the power,half the income and half the glory,the use of microeconomic theory in women's emancipation research

Summary Major fields of economic research to understand the development of women's integration into the economy and women's economic independence can be categorized into three main groups. First, theories that attempt to explain wage and earnings differences according to gender; second, theories that attempt to explain the division of work within the family, and third, theories that attempt to explain the determination of fertility and the combination of work and motherhood. This paper offers a review of these three areas of neo-classical theory as well as an evaluation as to what extent the theories are adequate to answer the questions of women's emancipation research.This article is a revised version of my inaugural speech held on May 30th, 1990, at the official assumption of the chair of Labour market issues with special attention to women's emancipation, at the University of Amsterdam.

Fertility projection based on birth order data--a Swedish approach

"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."
