Understanding Society, the UK Household Longitudinal Study includes a wide range of health measures, and in particular biomarker and genetic data. This makes it a unique resource for research on the economics of health. We review the main features of the biomarker data, how they are collected, and evidence on data quality. We also discuss examples of how these data have been used in economic research to date. 相似文献

This article describes a cost analysis of an employment programme available to people claiming incapacity benefits in the UK. The NDDP was delivered locally by contracted providers called ‘job brokers’. The cost analysis found great variation among job brokers' costs and profitability, much of which seems attributable to differences in job broker size. The methods described here will be useful in evaluations wherever multiple institutions are contracted by governments to deliver services, especially when these institutions are involved in several different programmes. 相似文献

In the early 1980s, disease susceptibility in short-season lentil landraces began to limit productivity in areas where relay cropping took place in Bangladesh. Since then, several improved high-yielding lentil varieties, which are resistant to rust and blight and suitable in the relay cropping system, have been released jointly by national and international research centers. This study used three methods, namely a panel of experts, a survey of 1000 households where the respondents named the variety they used, and DNA fingerprinting of seed samples collected from all lentil plots cultivated by survey households to estimate adoption. Double hurdle and instrumental variables regression methods were applied to the household survey and DNA fingerprinting data to identify determinants of adoption and measure their impacts. Of particular interest was whether estimates of adoption, determinants of adoption and impacts varied by method of variety identification. Results showed that the expert panel overestimated the adoption of more recent varieties while about 89% of the farmer-reported varieties were accurate, as verified by DNA fingerprinting. DNA fingerprinting appears to have little advantage for estimating the level of adoption in this case, where few varieties of lentils are found, local variety names do not exist, and most seed is obtained through a formal system. However, even under these conditions, determinants of adoption vary by identification method, and use of farmer-reported information on the variety can lead to erroneous conclusions about determinants of adoption. Because recent breeding efforts have focused on taste and cooking considerations, yield impacts were not significantly different from zero. 相似文献

This paper analyses managers' moral decision-making, and studies the role of ethical theories in it by following the research tradition using the multidimensional ethics scale. The research question is: what kinds of ethical dimensions do Finnish business managers reveal when they are making moral decisions, and how have these dimensions changed in the 1990s? This question is answered by examining what kinds of factors emerge when the multidimensional ethics scale is used to analyse Finnish managers' attitudes toward moral dilemmas. The results show that Finnish managers' decision-making reflects a variety of ethical theories. Teleological thinking is strongly emphasised by Finnish managers, and relativist thinking is used as well, but often combined with either deontology or justice thinking. In addition, a strong moralistic dimension emerged in Finnish managers' decision-making. The analysis was carried out in two different surveys in years 1994 and 1999, and the results show that the ways of decision-making were more complex at the end of the 1990s than almost six years earlier. 相似文献
