Asset pricing and energy consumption risk

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.     

The Effect of Fuel Price Changes on Fleet Demand for New Vehicle Fuel Economy

New vehicle purchases by private companies and government agencies, or ‘fleet’ buyers, represent a significant percentage of overall new vehicle sales in the United States. Yet little is known about fleet demand for new vehicle fuel economy including how it responds to fuel price changes. Using unique disaggregated data on fleet and household registrations of new vehicles from 2009 to 2016, we estimate how fleet demand for new vehicle fuel economy responds to fuel price changes. We find that fleet purchases of low fuel economy vehicles fall relative to high fuel economy vehicles when gasoline prices increase, a finding that is consistent with fleet buyers’ taking into account capitalization of fuel costs in the second‐hand market. Our estimates imply that raising gasoline prices by one dollar would increase fuel economy of new vehicles acquired by fleet buyers by 0.33 miles per gallon. We estimate a similar response for household buyers during the same period. This result justifies basing fuel economy responses to fuel cost changes on household data alone, an assumption widely used in the vehicle demand literature and the fuel economy valuation literature. We also find, however, that the response to fuel price changes varies across the types of fleet buyers: rental companies respond strongly to fuel price changes, whereas commercial and government buyers are insensitive. Our estimates imply that an increase in the federal gasoline tax would modestly increase fuel economy of vehicles bought by households and rental companies but would have little to no impact on fuel economy of vehicles bought by non‐rental companies and governments.

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?     

Structural changes in U.S. agriculture: Implications for African American farmers

Structural changes in U.S. agriculture, influenced by technological and institutional forces, have altered the economic and social characteristics of rural America, especially that segment of rural America populated by farmers and their families. Changes in the structure of agriculture have greater implications for small scale farmers, many of whom are African American, in that strategic options for their farm-firms are constrained to: increasing their farm size, exiting farming, and obtaining off-farm employment to survive. This article presents a rationale for public support of limited resource farmers, identifies structural trends in U.S. agriculture and their impacts on African American farmers, discusses economic problems unique to these farmers, and recommends needs for specific public policies and development programs.     

Making tourism work for the poor: Strategies and challenges in southern Africa

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.     

Exercise test on the older patient: is it still as predictive as for the younger patient?

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.

Recurrent PSA after prostatectomy for prostate cancer: implications of PSA doubling time

After radical prostatectomy for prostate cancer, men frequently develop detectable levels of prostate specific antigen (PSA). A slow rate of increase, as characterized by the PSA doubling time (PSADT) is the principal marker for a favorable prognosis. Data and results presented in 2 recent clinical articles studying cohorts of men with clinical stage T1/T2 prostate cancer are reviewed and used to develop mortality analyses. Life-table analysis shows a mortality ratio of 257% at 5 years for Gleason score < 8, PSA recurrence > 2 years after surgery for clinical stage T1/T2 disease, and PSA doubling time (PSADT) > 10 months. Markov modeling using transition probabilities derived from the clinical articles to develop a life table analysis yields a mortality ratio of 145% at 10 years for similar patients.     

Estimating net lottery revenues for states

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.
