Evidence which has emerged in the past few years indicates that the relative accuracy of population estimates derived from the ratio-correlation method and the difference-correlation method varies from state to state. In assessing the possible reasons why neither technique is uniformly more accurate, attention is focused on the temporal instability of the statistical relationships between symptomatic indicators and population change. The author concludes that further improvement in population estimates based on regression techniques is likely to be limited until demographers derive means of measuring and adjusting for these temporal changes. 相似文献

What determines how many adults live in a house? How do people divide themselves up among households? Average household sizes vary substantially, both over time and in the cross-section. In this paper, we describe how a variety of government policies affect living arrangements, intentionally or not. Using data from a survey of households in New York City, we find that these incentives appear to have an impact. Specifically, households receiving these housing and income subsidies are smaller on average (measured by number of adults). The impacts appear to be considerably larger than those that would occur if the programs were lump-sum transfers. Small average household size can be extremely expensive in terms of physical and environmental resources, higher rents, and possibly homelessness. Thus, we encourage policymakers to pay greater heed to the provisions built into various social policies that favor smaller households. 相似文献

Health expectancies of the states ‘Disability-free’ and ‘Disabled’ are estimated for Australian females and males aged 60
and over, both by cohort from 1980 and current for survey years 1981, 1988, 1993 and 1998. Modifications of recently developed
logistic regression techniques are used rather than the standard 1971 method due to Sullivan. Results from the three later
surveys are broadly similar and differ in important respects from those of the 1981 survey. Based on the last three surveys
our estimates support the view that, depending on age, two-thirds or more of the increase in female life expectancy over the
decade 1988–1998 is spent in the Disabled state. The situation is worse for elderly men, for whom all of the increased years
of expected life are estimated to be spent in the Disabled state. The findings do not support rectangularization of the survival
curve or Disability-free survival curve. 相似文献

We present theoretical results for large-file distribution on general networks of known topology (known link bandwidths and router locations). We show that the problem of distributing a file in minimum time is NP-hard in this model, and we give an O(logn) approximation algorithm, where n is the number of workstations that require the file. We also characterize our method as optimal amongst the class of “no-link-sharing” algorithms. 相似文献

Considering the effects of globalisation, the increase of production and energy costs, and the introduction of advanced technologies, companies need to change their way of doing business if they want to stay competitive. One way of doing this is to establish collaborations with suppliers, distributors and retailers, in order to exchange products efficiently and create value for customers. Nevertheless, the structure of the collaboration must be designed carefully and some coordination mechanisms must be implemented to support this way of doing business. In this article, we first analyse: why companies work together, how they should build their partnership, and which strategies they can implement to facilitate coordination of supply chain activities. We then report a case study of collaboration in the forest industry that shows the benefits of implementing coordination mechanisms as well as the necessity of using incentives to better share these benefits. 相似文献

This paper provides an efficient method to measure utility under prospect theory. Our method minimizes both the number of
elicitations required to measure utility and the cognitive burden for subjects, being based on the elicitation of certainty
equivalents for two-outcome prospects. We applied our method in an experiment and were able to replicate the main findings
on prospect theory, suggesting that our method measures what it is intended to. Our data confirmed empirically that risk seeking
and concave utility can coincide under prospect theory. Utility did not depend on the probability used in the elicitation,
which offers support for the validity of prospect theory.
