This paper documents a strengthening in the lead of stock index futures returns over stock index returns around macroeconomic information releases. Some evidence of a strengthening in feedback from the equities market to the futures market and weakening in the lead of the futures market around major stock‐specific information releases is also provided. This is consistent with the hypothesis that investors with better marketwide information prefer to trade in stock index futures while investors with stock‐specific information prefer to trade in underlying stocks. A small weakening in the contemporaneous relationship between stock index futures returns and stock index returns around both types of releases is also documented. This is consistent with disintegration in the relationship between the two markets associated with noise induced volatility. One by‐product of this study is new comparative evidence on the performance of adjustments for infrequent trading of index stocks based on a commonly used ARMA technique versus recalculation of the stock index using quote midpoints. The results suggest that the quote midpoint index performs at least as well as the ARMA adjusted index across the entire sample period, as well as around the different types of information releases. © 2000 John Wiley & Sons, Inc.

The Internet promises many opportunities for consumers who shop online. While prior studies identify problems with online access for persons with disabilities, research has not examined whether consumers with disabilities shop online similarly to persons who are not disabled. The study attempts to fill this gap in two unique ways. First, this paper specifically considers the frequency of online shopping, the amount spent, and reasons for shopping online among both disabled and non-disabled persons. In addition, the study groups persons with disabilities into six major categories according to disability type rather than aggregating into one general category. Telephone surveys of 1053 persons reveal both differences and similarities that suggest opportunities for improving online access and developing a richer understanding of the online shopping motivations and needs of persons with disabilities.  相似文献

When successful and ethical managers are alerted to possible organizational wrongdoing, they take corrective action before the problems become crises. However, recent research [e.g., Rynes et al. (2007, Academy of Management Journal 50(5), 987–1008)] indicates that many organizations fail to implement evidence-based practices (i.e., practices that are consistent with research findings), in many aspects of human resource management. In this paper, we draw from years of research on whistle-blowing by social scientists and legal scholars and offer concrete suggestions to managers who are interested in encouraging internal reporting of problems requiring attention, and to observers of questionable activity who are considering reporting it. We also identify ways that research suggests policy-makers can have a more positive influence. We hope that these suggestions will help foster evidence-based practice regarding whistle-blowing.  相似文献

To constrain the use of intangible assets in tax-motivated state income shifting, many U.S. state governments adopted addback statutes. Addback statutes reduce the tax benefits that firms can gain from creating intangible assets such as patents. Using a sample of U.S. public firms, we examine the effect of addback statutes on corporate innovation behavior. First, the adoption of addback statutes leads to a 4.77 percentage point decrease in the number of patents and a 5.12 percentage point decrease in the number of patent citations. Second, the “disappearing patents” resulting from addback statutes have significant economic value. Third, after a state adopts an addback statute, a firm with material subsidiaries in that state assigns fewer patents to subsidiaries in zero-tax states, whereas the number of patents assigned to the other states does not change. Overall, our findings suggest that addback statutes impede corporate innovation.  相似文献

This paper reviews the literature on economic development as it relates to indigenous people in the United States and Canada, and focuses on how institutions affect economic development of reservation and reserve economies. Evidence shows that strong property rights to reservation and reserve land and natural resources, whether communal or individual, are and always have been important determinants of productivity. Political and legal institutions that are perceived as stable and predictable to tribal members and to non‐Natives also improve economic opportunities for indigenous people living on reservations and reserves. Research reviewed here also shows that culture and acculturation are important in the development process. Although our emphasis is on North America, the findings are applicable to indigenous people in other parts of the world and shed light on growth questions that loom large for developing countries around the world.  相似文献

Recent studies show firms suffering drug recalls experience security losses many times larger than any reasonable measure of their direct cost. We discover that the implied standard deviation of stock returns from the Black-Scholes option pricing model significantly increases after a drug recall. The implied standard deviation provides a good proxy for the stock's ex ante beta. The higher systematic risk after a product recall must raise the discount rate used by investors. After a recall, stock prices are reduced in line with the lower expected future earnings and are further reduced because of a higher discount rate.  相似文献
