This paper proposes energy consumption in the US as a new measure for the consumption capital asset pricing model. We find that (i) industrial energy growth produces reasonable values for the relative risk aversion coefficient and the implied risk-free rate; (ii) compared to alternative consumption measures, industrial energy performs well in explaining the cross-sectional variation in stock returns with the lowest implied risk aversion and pricing errors; (iii) the industrial energy consumption risk model performs equally well as the Fama–French three-factor model in the cross-sectional asset pricing tests; and (iv) total energy consumption risk is priced in the presence of the Fama–French factor risks. 相似文献

In 1998, in response to the escalating problem of violence and its impact on all sectors of the society, the Ministry of Health (MOH), Jamaica, established a pilot violence-related injury surveillance system (VRISS) in the country's leading public hospital, the Kingston Public Hospital (KPH) situated in the nation's capital. After six months' operation, VRISS was extended to include all injuries. Nine months later, the Jamaican Injury Surveillance System (JISS) was successfully introduced to four other hospitals and has been in operation since. Extension to an additional six institutions was implemented at the end of 2001. What were the challenges faced in introducing an injury surveillance system into the Accident &; Emergency Department (A&;E) of a general hospital, how they were overcome and what were the lessons learnt in the process? 相似文献

This article analyses strategies for 'pro-poor tourism' (PPT), ie strategies that increase the benefits to poor people from tourism development. Based on an international review of six pro-poor tourism case studies, it outlines the wide range of pro-poor tourism strategies used and their impacts to date, with particular focus on southern African case studies. By analysing their progress, problems and the critical factors influencing them, the article identifies implications for the way forward. This review underpins four propositions. First, despite commercial constraints, much can be done to enhance the contribution of tourism to poverty reduction, and a 'PPT' perspective assists in this endeavour. Secondly, PPT strategies can, and should be, incorporated by all actors in tourism, whether in government or business, at local or policy level. Thirdly, a wide range of impacts on poor people, going well beyond jobs, need to be recognised and enhanced. Finally, PPT strategies are difficult, but particularly relevant in southern Africa given the challenges of economic and political transformation, as well as the opportunity to influence international discussions on 'sustainable tourism' at the World Summit on Sustainable Development in Johannesburg in 2002. 相似文献

Exercise testing predicts both cardiac events and mortality after age 65, just as it does for younger patients. In both age groups, functional aerobic capacity itself is a potent indicator of mortality risk. In the elderly, achievement of predicted functional aerobic capacity identifies favorable mortality even in the presence of CAD and CAD risk factors. 相似文献

Based on 1980–95 data, this paper estimates and forecasts net lottery revenues for states with and without lotteries. This
study indicates that a multi-state estimation is improved when a time-series and cross-section technique is used. Forecasting
results are also improved when unequal time series in the data and less-than-full first years of operating lottery are controlled.
For states without lotteries, the time-series and cross-section estimation indicates that only two of 14 states without a
lottery would have generated net lottery revenue of more than $100 million. The number increases to five of 14 in the cross-section
estimation. 相似文献

Using data for a one-year period from the Kingston Public Hospital (KPH) in Jamaica, we describe patterns of non-fatal violence-related injuries, and carry out simulation analysis to estimate rates of hospital admission under various injury reduction scenarios, and the potential savings that can be realized by reducing violent crimes. In this period there were 6107 registered violence-related visits to the KPH representing 11.5% of all recorded visits. Of these 16.6% (1001) were admitted. The most common methods of inflicting injury was by stabbing (52.1%), blunt injuries (37.9%) and gunshot wounds (7.3%). Multivariate analyses indicated that gunshot injuries, stab injuries, being male between the ages of 15 and 44 years, receiving the injury in November or December, and being injured by a stranger or unknown assailant, were significant correlates of a higher probability of admission. Simulation analysis with various injury reduction scenarios indicated decreases in the probability of admission ranging from 12% to 44%, with estimated savings of up to 31% of the annual supplies budget of KPH. 相似文献

Experimental work in economics prompted the development of theories of other‐regarding behavior. In this article we reanalyze two classic public goods experiments and focus on the nature of individuals' responses to others' behavior in order to help distinguish alternative motives for giving, including altruism, warm glow, reciprocity, and inequality aversion. Analysis that allows for asymmetric feedback responses generates support for inequality aversion motives but little for reciprocity (matching), altruism, and warm glow. We conclude that individual‐level analysis of existing public goods data can provide more insightful, informative estimates of treatment effects. 相似文献
