This study uses a methodology that is independent of beta estimates to provide empirical evidence on the success of market timing by mutual fund managers. A fund's success at market timing is evaluated by determining if the percentage of the portfolio invested in stocks increases prior to an upturn in the general level of stock market prices and declines prior to a downturn in the level of stock prices. No evidence is found that managers possess, as a group, any market timing ability. 相似文献

The betting markets for totals in college football and arena football provide additional evidence of bettor preference for
scoring. The results for college football and arena football markets are similar to those found in the professional football
and professional basketball totals market. In all of these leagues, the overs are overbet. We suggest that there is a clear
preference for bettors to bet the over and the extent of the bias depends upon the volume of uninformed bettors to informed
bettors and limits placed on bets in these markets. 相似文献

Personality and other attributes,qualities, abilities and opinions of some ‘A’ level design students
John Tyers 《International Journal of Technology and Design Education》1991,1(3):159-170
Many claims have been made of a subjective nature that some students studying A level Design develop certain personal qualities and attributes not found in some students who study other academic A levels. The research describes attempts to quantify these claims and as a result provides a firmer basis for the understanding of the effects on students of studying design. 相似文献

Optimistic overconfidence (OO), that is, being certain of success only to end up disappointed, represents a potentially catastrophic error. However, few studies have identified which entrepreneurial actions are associated with it. To explore this issue, we examined 55 small companies and found that OO of product success was positively related to introducing products that required more resources and were more pioneering. Furthermore, satisfaction with company performance had a curvilinear (U-shaped) relationship with overconfidence. Both high and low levels of satisfaction were associated with greater OO in product introductions. In addition, the bias was positively correlated with entering hostile environments; that is, environments that are characterized by intense competition that threatens a firm and its introductions. Contrary to expectations, however, OO was negatively associated with environmental dynamism; defined as environments that embody frequent and large changes. The research also compared general knowledge overconfidence to OO, concluding that each represents a distinct bias with distinct effects. 相似文献

Health and disease reflect broad social conditions including economic, environmental, and cultural components. The impact of challenging housing conditions experienced by low-income African American households on their mental health is an example of this principle. Do physical housing conditions, the presence of roaches and rodents, plumbing defects, and heating/cooling problems contribute to mental health dysfunction such as being depressed, feeling worried, feeling sad, feeling helpless, and feeling emotionally upset? To address this research question, a sample of 128 households that originally lived in public housing in Washington, D.C. were surveyed. These households had been relocated to other low-income housing during the demolition and reconstruction phase of a HOPE VI project, some to alternative public housing developments and others to private units based on vouchers. The survey included self-reports by heads of household on their housing conditions and mental health status using Likert scales. The survey also asked participants for demographic, socio-economic, and physical health data and for information on neighborhood characteristics. Correlation and regression analyses were used to estimate the impact of building structure, building systems, neighborhood characteristics, physical health, and socio-economic/demographic variables on mental health stresses. Specific housing issues included the number of bedrooms, plumbing, heating, cooling, rodents, roaches, and building security (the independent variables). Mental health stresses (the dependent variables) included feeling depressed, nervous, anxious, sad, helpless, and having trouble concentrating. Several alternative specifications and models were used and estimated. They generally demonstrated strong overall explanatory value. The findings from these models suggested that challenging housing conditions significantly contributed to many mental health disorders. For example, in the 2SLS model of “problem being depressed”, the condition of the apartment (β?=?0.278, t?=?2.022) and plumbing (β?=?0.182, t?=?2.145) were significant and the model’s explanatory power was reasonable with an adjusted R2?=?0.221. Many non-housing control variables were also significantly associated with mental health challenges. 相似文献

General equilibrium models are constructed of four Asia‐Pacific economies that differ according to their levels of development, the comparative sizes of their manufacturing sectors and their patterns of comparative advantage and trade protection. The countries chosen are Australia, an industrialized importer of manufactures; Japan, an industrialized exporter; the Philippines, a developing importer; and the Republic of Korea, a developing exporter. Manufacturing industries are characterized as comprising identical oligopolistic firms producing homogeneous goods that are differentiated from competing imports. Oligopoly behavior notwithstanding, trade reforms are found to yield conventional results in that net economic gains are small while implicit transfers are substantial. More competitive (non‐collusive) pricing by oligopolistic firms, which might be achieved through reform of competition law and trade practices surveillance, yields larger net gains and these gains tend to accrue to all domestic primary factors. Such reforms also yield substantial interaction between oligopoly behavior and economic and industrial structure. 相似文献

This article shows that share repurchase announcements create value for shareholders when the shares of the industrial firm sell at a discount from the value of the underlying assets, even when shareholders and managers share full information about the firm's prospects and the firm's operating performance is not expected to improve. The value created by capturing the discount on the repurchased shares is a function of only two variables: the percentage discount prior to the announcement and the proportion of shares to be repurchased.
For a sample of 100 companies selling below net asset value, the authors report that the excess stock returns surrounding their announcements of open market repurchases are (significantly) positively associated with the authors' estimates of the value captured from buying shares at a discount. Moreover, the stock market's response to repurchase announcements by companies that are selling at a discount is considerably more positive than to announcements by firms selling at a premium. 相似文献
