We identify finance professors’ opinions on the efficiency of the stock markets in the United States and assess whether their views on efficiency influence their investing behavior. Employing a survey distributed to over 4,000 professors, we obtain four main results. First, most professors believe the market is weak to semi-strong efficient. Second, twice as many professors passively invest than actively invest. Third, our respondents’ perceptions regarding market efficiency are almost entirely unrelated to their trading behavior. Fourth, the investment objectives of professors are, instead, largely driven by the same behavioral factor as for amateur investors–one's confidence in his own abilities to beat the market, independent of his opinion of market efficiency. 相似文献

Universities and colleges continue to face constraints related to classroom space and faculty time, thus increasing the need to consider options such as hybrid courses that can leverage available resources. This article discusses the benefits of a hybrid course, as well as its design and implementation at a large, public university. In addition, for universities that use the introduction to risk and insurance course as a significant course for attracting majors, we identify the benefits for students from the use of hybrid courses, such as the variety of materials and activities utilized, as well as the flexibility in scheduling. This information may be useful in marketing the course so that it will be immediately attractive to students. 相似文献

Predictions of firm-level credit spreads based on the current spot and forward credit spreads can be significantly improved upon by using the information contained in the shape of the credit-spread curve. However, the current credit-spread curve is not a sufficient statistic for predicting future out-of-sample credit spreads; predictions can be significantly improved upon by exploiting the information contained in the shape of the riskless yield curve. In the presence of credit-spread and riskless factors, other macroeconomic, marketwide, and firm-specific risk variables do not significantly improve predictions of credit spreads. These results have important implications for credit-spreads modeling as well as for better understanding corporate capital structure and risk management policies. 相似文献

Previous research has examined the demand for life insurance policy loans using aggregate policy loan data. In contrast, we use a detailed household survey data set containing life insurance and policy loan information to alternatively, and in some cases more directly, examine the four hypotheses traditionally associated with policy loan demand. Our research provides the first U.S. evidence (in the post–World War II period) in support of the policy loan emergency fund hypothesis. In particular, we find that the more detailed emergency fund proxies used here reveal a significantly positive relation between loan demand and recent expense or income shocks. 相似文献

We investigate how closely NBA teams play up to their potential. We find that shooting, rebounding, stealing the ball and blocking shots raise the number of potential wins while turnovers lower it. We also learn that better coaching and defensive prowess raise a team's win efficiency. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

This article examines associations between home care workers' health, and non-standard hours and insecurity. Health refers to symptoms of stress and musculoskeletal disorders (MSDs), non-standard hours refer to part-time and casual hours, and insecurity refers to job and employability insecurity. Data come from our 2002 survey of 532 home care workers (nurses, therapists and personal support workers) in a medium-sized city in Ontario, Canada. Path analysis regression results for the conceptual model show that (1) part-time and casual hours and job insecurity are positively and significantly associated with symptoms of stress, (2) the associations between part-time and casual hours and MSDs are mediated by symptoms of stress, and (3) job and employability insecurity are directly associated with MSDs. Results provide evidence that non-standard hours and insecurity must be addressed in order to improve home care workers' health. We show the detrimental effects of non-standard hours and insecurity on workers' health, and the results have implications for employers, human resource managers, trade unionists and government policy-makers. 相似文献

This paper discusses what I believe a researcher ought to keep in mind when he/she tries to find a research topic and assesses the probability of success. In this context I think of success as a paper that becomes known over time and, generally, extensively cited. My discussion will lay out some useful ‘pointers’. I will also try to provide something resembling a ‘proof in the pudding’ by listing a number of specific research topics, each of which can be spelled out in a few sentences. My aim is to persuade the reader that research topics can rely on straightforward ideas as opposed to a specific set of antecedent papers. In this respect, I argue that the best research questions derive from an acute sense of how the world works as opposed to more or less stylized ‘theories’ originating in academia. 相似文献

This paper describes accrual output based budgeting (AOBB) systems and examines their adoption in Australia. An analysis of claims made about AOBB systems by central agency reformers is set out, and the conclusion offered that these claims are fundamentally rhetorical in their characteristics. These rhetorical claims are contrasted against a critical analysis which suggests that despite the claims made by reformist elements in favour of the adoption of these systems, the structural and empirical elements of AOBB systems as implemented in Australia raise considerable doubts as to whether suggested benefits will be realised in practice. 相似文献
