"A bulk of public resources in developing countries is devoted to the subvention of population control and health investments. The effects of these programs have been evaluated in this study with household and community data from Bangladesh. The results suggest that subsidy on family planning and secondary school would be most effective in the achievement of harmonious goals of reducing fertility and mortality and fostering investments in child education."  相似文献

Do jobs follow people or people follow jobs? A meta-analysis of Carlino–Mills studies. Spatial Economic Analysis. This study examines the classic question as to whether ‘jobs follow people’ or ‘people follow jobs’ by performing a meta-analysis of 321 results from 64 Carlino–Mills studies. It is found that the results are highly divergent, but that more results point towards ‘jobs following people’ than towards ‘people following jobs’. When it comes to the reasons for the variation in results, we find that the results are mostly shaped by the geographical location, spatial resolution, and population and employment characteristics present in the data, as well as by the model’s specification, its functional form and the spatial weight matrix specification.  相似文献

This study focuses on the identification of regional business clusters as a primary step in the design and implementation of cluster-based development strategies. A methodology that has not been used previously to identify clusters is applied to data on inter-industry linkages from the input–output table of a region in northern Spain. The first advantage of this approach, hierarchical clustering on principal components (HCPC), over the use of factorial analysis alone, is that it involves the application of objective clustering techniques to the principal components analysis results, which leads to a better cluster solution. A second advantage is derived from using a mixed algorithm for the clustering process – a combination of the Ward’s classification method with the K-means algorithm – which improves the robustness of the final results.  相似文献

The ‘wage space’, which is defined as the sum of price inflation and labour productivity growth, has played a major role as an indicator of allowable wage increases in the post-war wage negotiations in the Netherlands. This paper shows that: (a) wages and the wage space are co-integrated; (b) the deviation between wages and the wage space may act as an error correction term in the wage equation when both variables are identified as I(2); and (c) political consensus and the threat of labour conflicts (rather than actual strike activity) may be identified as the ‘mechanism’ behind this error correction in the wage equation.  相似文献

Simultaneous relations between various components of the regional supply of labor and the situation on the regional labor market are developed. There is a distinction between migration, participation and commuting. Conventional research only devotes attention towards the partial relation between one of these components and the regional labor market situation. However, many decisions people make, involve a simultaneous approach towards participation, commuting and migration. This approach is operationalized at a macro-level by constructing a simultaneous supply model. For the specifications we go back to standard literature. In each of the equations, apart from variables that are specific for the particular function, special attention is given to the interrelation between the three supply variables. An overall simultaneity is described by a fourth endogenous variable: unemployment; this variable is explained by employment, participation, netmigration and netcommuting. A combined time-series/cross-section-analysis is used to estimate the model.

Surprisingly it appears that in comparison with OLS parameter- and t-values of the supply-equations are not affected by the use of simultaneous estimation techniques. Only for the unemployment-equation there are significant changes.  相似文献

Accurate estimation of the equity premium (the expected difference between the returns to a well-diversified stock market portfolio and a riskfree asset) is of central importance in many applications of finance theory including project appraisal and portfolio selection. The standard approach is to take the average observed excess returns to the market over some recent time period (sometimes referred to as the ex post equity premium) and apply this as an unbiased estimate of the ex ante equity premium. The paper reviews the problems associated with such an approach and contrasts it with alternative theoretical techniques.  相似文献

This paper is concerned with the search for locally optimal designs when the observations of the response variable arise from a weighted distribution in the exponential family. Locally optimal designs are derived for regression models in which the response follows a weighted version of Normal, Gamma, Inverse Gaussian, Poisson or Binomial distributions. Some conditions are given under which the optimal designs for the weighted and original (non-weighted) distributions are the same. An efficiency study is performed to find out the behavior of the D-optimal designs for the original distribution when they are used to estimate models with weighted distributions.  相似文献

Although economists commonly view the accumulation of human capital as a key driver of economic development, what drives cross-country differences in human capital accumulation remains poorly understood. I use an epidemiological approach involving second-generation migrants to test for a possible cultural gradient in individuals’ propensity towards human capital accumulation. Results indicate a strong relationship between country-of-origin culture and human capital accumulation and are robust to using years of education instead of individuals’ engagement in human capital accumulation as the dependent variable. Drawing on dimensions of cultural differences identified in culture frameworks developed by cross-cultural researchers, results further suggest that cultural emphasis on intellectual autonomy helps explain part of the observed differences in human capital accumulation. However, further work is needed to complete our understanding of the cultural roots of individuals’ propensity towards human capital accumulation.  相似文献
