This study examines seaonality in three industry specific stock market indices; the Standard and Poor's (S&P) 20 Transportation, the S&P 40 Utilities, and the S&P 40 Financial. The results support the existence of a weekend effect in the transportation index. There is no evidence of a weekend effect in the utilities and financial indices. Both the transportation and financial indices exhibit the January effect. The utilities index, however, shows no evidence of a January effect. The finding of a weekend and a January effect at the industry level is significant because select mutual funds enhance the ability of investors to capitalize on such anomalies.  相似文献

Though uninsured depositors are recognized as a source of market discipline, the possible disciplinary effect of decisions made by fully insured depositors have gone largely unexamined. Using proprietary administrative deposit data at the account level, this paper analyzes depositor behavior at a recently failed institution. The results suggest that although uninsured deposits exited at a greater rate than insured deposits, the vast majority of deposits withdrawn were fully insured. Among types of deposit accounts, the rates of withdrawal for fully insured individual, joint, and trust accounts were relatively high. Uninsured business account owners were highly sensitive to the bank's deteriorating condition. In contrast, owners of uninsured individual retirement accounts effectively exerted no market discipline. The opinions expressed in this paper are ours and do not necessarily reflect those of the Federal Deposit Insurance Corporation. All errors are our own.  相似文献

Despite the social, economic and ethical problems facing government in the Czech Republic, there are positive signs of a growing concern for ethical business, including the development of codes of conduct and a striking example of new corporate social responsibility. Dr Bohatá is a member of the Economics Institute of the Academy of Sciences, Politickych Veznu 7, 111 21 Prague 1, and an Associate Editor of this Review.  相似文献

We explore the welfare implications of agricultural expansion in the Brazilian Amazon by comparing spatially explicit estimates of soybean rents and the value of ecosystem services. Although these estimates are generated from different datasets, models, and estimation techniques, the values are comparable, such that the value of ecosystem services is greater than soybean rents for about 61% of the total area and 24% of the area where soybean rents are positive if protected areas are well enforced. Based on the balance between the benefits and costs of conversion, failure to value ecosystem services reduces total social welfare by 7.13 billion dollars annually relative to an optimum. Policy instruments that internalize the value of ecosystem services via protected lands, land conversion taxes, conservation subsidies, or excise taxes can avoid much of this loss. Regardless of intervention regime, policy makers should be cognizant of the diminishing net benefits of converting natural ecosystems to agriculture. Realizing the final 3.8% requires the conversion of an additional 15% natural ecosystems to soybean production.  相似文献

The aim of this study is to provide a foundation for researchers and managers to discuss and resolve difficulties associated with research and development (R&D) target‐setting. While multiple studies mention the difficulty of R&D target‐setting, few have compiled reasons for these difficulties or addressed this issue in detail. This paper provides one of the first studies outlining reasons for R&D target‐setting difficulties through a literature review. It also provides an initial set of analyses and results after applying an emerging quantitative method, Technology Forecasting Using Data Envelopment Analysis (TFDEA), to illustrate these difficulties step‐by‐step to commercial airplanes. Results include determining the state of art in commercial airplane technology and technological rate‐of‐change variants in setting R&D targets.  相似文献
