Use of registers and population censuses as sampling frames in Great Britain

The use of official data sources as sampling frames for numerous government surveys in the United Kingdom is described. "The great majority of these surveys use registers of various kinds as sampling frames. Some of these registers are intended to cover all addresses in the country in which there are private households. Other registers relate to specific sub-groups of the population. Each of the general registers has advantages and disadvantages but none is ideal for sampling purposes. In recent years nearly all samples required of the general population have been drawn, by automated means, from the Postcode Address File, although the balance of advantages of this system need to be continually monitored and evaluated." Reasons why the census is not often used as a sampling frame are considered.     

英国生产服务业发展现状分析

本文利用1968-2002年间的英国投入产出表,将英国服务业中用于中间需求的部分界定为生产服务业,并由此分析了英国生产服务业的发展趋势及现状。分析发现,英国生产服务业增加值占服务业和GDP比重不断上升,与人均GDP之间存在显著的正相关关系。生产服务业中为农业、工业服务的部门比重不断下降,而为服务业服务的部门比重不断上升。文章最后分析了英国生产服务业发展变化趋势对我国的几点启示。     

Mandatory Pensions and Personal Savings in The Netherlands*

The Netherlands has a relatively generous social security system and a wide coverage of individuals by private (occupational) pension schemes. Total household savings are rather high and fairly stable, although the amount of contractual savings apears to be going up at the expense of non-contractual (free) savings. Using an approach originally pioneered by Feldstein (1974) we employ microdata to investigate the displacement effect of security and pension wealth on free household savings. It turns out that the data available are too noisy to make precise statements about the displacement effects. Our results do suggest, however, that a one-for-one displacement of free savings by social security is consistent with the data. For pensions such a complete offset is less likely. This suggests that increase of coverage by private pensions is an effective way of raising savings.
