Employment,schooling and productivity growth 总被引:1,自引:1,他引:0
Summary This paper presents an empirical analysis of labour demand and labour productivity growth in The Netherlands. Assuming an aggregate production function with as factors capital and 3 types of labour, distinguished by educational attainment, cost minimization leads to a set of 3 labour demand relations to be estimated on time series data. Using the estimates and the implied elasticities, aggregate labour productivity growth is decomposed into factor substitution, autonomous factors, labour time shortening, economies of scale, utilization rates and the increased educational level of the working population. The contributions of substitution, utilization rates and education appear to be substantial, notably in the seventies.

The author examines recent urban development in Indonesia. "Analysis of urban developments in Indonesia has been hampered in the past by weak data. Recently, the National Urban Development Strategy (NUDS) project has generated a set of improved data. This paper aims at elaborating and supplementing the NUDS study. After a discussion of definitional problems, an analysis is carried out of urban growth rates at the provincial level. Private investment is shown to be a principal determinant of urban growth rates. Other significant determinants are rural immigration and the present level of urbanisation. Private investment is shown to be strongly biased towards provinces with large urban areas. In addition, polarisation is studied at the level of individual cities. It is found that a period of rapidly increasing polarisation has come to an end during the last decade." 相似文献

Issues such as global warming, ozone depletion, insufficient landfill capacity, and excess packaging are foremost on the minds of consumers. Companies face a myriad of environmental challenges, but they also recognize the opportunities to be gained by implementing responsible marketing action plans. 相似文献
