The suitability of age-specific birth proportions (ASBP), or percentage distribution of births, as a rough and ready index of fertility change was analyzed by establishing a theoretical framework for its limitations and uses. The discussion suggested that the utility of ASBP as an indicator of fertility change depends on the characteristics and behavior of the population being considered. The concept was then empirically applied to birth trends in Japan and Singapore for 2 different time periods. Analysis suggested that ASBP trends in Japan reflected changes in age-specific fertility rates relative to general fertility rate as well as trends in parity distribution. The Singapore analysis was more complicated, raising different issues. As very limited empirical work has been done on ASBPs, the utility of ASBPs as an indicator of fertility change cannot be definitely ascertained. It was suggested however that ASBP trends may be applicable in countries where the age distribution of fertile-aged women is fairly stable. More empirical research should be done on ASBP trends in other countries, the behavior of A matrix as discussed in this paper, and useful empirical relationship of ASBP with other fertility measures.  相似文献

Summary In an earlier paper [Rao 1966] an exact expression for the variance of the ratio estimator under theMidzuno-Sen sampling scheme is obtained and here we study some of the interesting properties of the coefficients involved in this expression which depend on the auxiliary information. Use of these coefficients is made of in finding out an exact expression for the Bias and Mean Square Error of the ratio estimator under Simple Random Sampling With-Out Replacement (SRSWOR) scheme.  相似文献

城市发展战略是城市管理导引的主导性环节。城市产业发展战略是城市发展战略的核心内容。在当前形势下,我国城市产业发展战略面临以下三大课题:面对“入世”对我国提出的挑战和机遇,城市产业应提出“应对战略”;面对知识经济的到来和我国与发达国家存在的差距,城市产业应提出“追赶战略”;面对我国城市产业发展自身长期存在的不协调和不适应问题,城市产业应提出“调整战略”。  相似文献

This short note estimates using the Kmenta's (1967) approximation, a constant elasticity of substitution (CES) production function for Australia for 1960–2004. It is found that the elasticity of substitution is 2.44, technical progress is capital augmenting and the steady‐state growth rate (SSGR) of Australia is about 0.34%.  相似文献

This paper provides industry-of-origin comparative estimates of real output and labour productivity in the Indonesian and Australian manufacturing sectors. It makes binary comparisons for the benchmark year 1987, and extrapolates the 1987 benchmark backward and forward using national time series, to derive comparisons for the years 1975–90. Expressed in ‘purchasing power parities’ (PPPs), the gross value of output and value added in Indonesian manufacturing in 1987 was 40% and 34% of the respective Australian levels. In 1987 the Indonesian manufacturing price level was 74% of the Australian level, and Indonesian manufacturing labour productivity was 16% of that in Australia. 1975 to 1990 was a period of catch-up. The Indonesian manufacturing price level declined from 105% to 60% of the Australian level, while labour productivity increased from 12% to 17% of the Australian level. The catch-up was greater from the early 1980s onwards.  相似文献

Joint space multidimensional scaling maps are often utilized for positioning analyses and are estimated on survey samples of consumer preferences, choices, considerations, or intentions so as to provide a concise spatial depiction of the competitive landscape including relevant dimensions or attributes, competing brands, and consumers in the same joint space representation. Care has to be given concerning the underlying scale properties of such survey data so as not to distort the resulting joint space positioning map. We present a new joint space multidimensional scaling procedure for positioning analyses for displaying the structure in such survey data when such common ordered successive category measurement scales such as Likert, Edwards, semantic differential, etc., are employed. We present the technical details of this stochastic ordered preference multidimensional scaling vector model as well as the maximum likelihood estimation-based algorithm devised for parameter estimation. Favorable comparisons are made with several existent multidimensional scaling methods in representing the internal structure for such data in marketing positioning studies. An actual commercial positioning application concerning large sports utility vehicles consideration to buy judgments is presented with predictive validation comparisons with other multidimensional scaling joint space procedures.  相似文献
