In this paper the role of expenses in explaining closed-end fund discounts is re-examined. A present value model is developed to illustrate the relationship between expenses and discounts. Earlier studies find that discounts are not related to management fees. In this paper, using a larger sample over a longer and different period and a better specification of the expense variable consistent with the model developed, discounts are found to be significantly related to expenses. The relationship between expenses and discounts holds in the presence of other control variables.  相似文献

A conceptual framework of anonymity in Group Support Systems   总被引:2,自引:2,他引:0  
As the development and use of automated systems for collaborative work grows, the need for a better understanding of these systems becomes more important. Our focus is on one type of system, a Group Support System (GSS) and, in particular, on one important aspect of a GSS—anonymity. A conceptual framework for the study of anonymity in a GSS is presented, which describes the general classes of variables and their relationships. These variables include the factors that influence anonymity in a GSS, types of anonymity, and the effects of anonymity on a message sender, receiver, group process, and outcome. Each of these variables is discussed with working propositions presented for important group process and outcome measures. The objectives of this article are to highlight the importance and complexity of anonymity, to act as a guide for empirical investigations of anonymity, and to influence future GSS development and use.  相似文献

Search and Liquidity in Single-Family Housing   总被引:5,自引:0,他引:5  
A two-stage least squares model of housing prices is estimated with data collected from 3358 single-family home transactions. The results provide evidence for an optimal marketing period and indicate that a liquidity premium is priced in single-family home sales. Consistent with the hypothesis derived from economic search models, the model shows higher selling prices for houses having longer expected marketing periods. The model also shows a price premium for houses that sell faster than expectations. This effect supports the concept that liquidity is a value-enhancing characteristic.  相似文献

Through a case study of a large industrial company ( TRW ) , this paper examines the history and functioning of independent local unions ( ILUs ). TRW's ILU plant wages were about the same as those at affiliated union plants and higher than those at nonunion plants. The premium explains why TRW and other companies discarded ILUs in favor of a "new" nonunion model. Yet ILUs can remedy some of the defects in that model and thus belong on the policy and research agenda  相似文献

This paper examines the behavior of the risk premium component of currency forward rates. Analyzing forward rates of one, two and three-month maturity, we find that the power of forward rate as a predictor of future spot rate decreases with the length of contract maturity. Further, we find that the proportion of the variance of the forward premium which is due to the variation of the risk premium is larger than the proportion due to the expected spot rate change for all currencies except for the Canadian dollar. This proportion also increases with the length of maturity.  相似文献

Young children's memory for television advertising is important in order for children to recognize brands in stores and/or to recall the brand name in making a purchase request. Two experiments showed that the use of visual advertising retrieval cue (a green frog as the brand character) improved memory performance and brand evaluations. Study 1 (n = 40) showed promise in the cue's assistance in children's recalling the brand name (cued recall) from the ad memory trace. Study 2 (n = 40) contained multiple exposures to the ad, which resulted in greater free recall and in support for the cue's assistance in better access of the brand name from the ad memory trace (cued recall). Affected ad memory resulted in more favorable brand evaluations and intent to request the brand's purchase. © 1994 John Wiley & Sons, Inc.  相似文献

An examination of the ethical perceptions of business students using Macobby's head/heart traits and a comparison to earlier studies of managers, accountants, and business students is made. The data were collected at three universities that are similar in size, enrollment and degree programs within the College of Business. Results indicate that present day business students are no less ethically inclined than are their business counterparts in previous eras. In general head traits dominated over heart traits, an indication that business schools continued to do a good job emphasizing and developing analytical skills but a poor job of developing the qualities of the heart that are generally associated with ethical behavior. The implications of these findings are discussed.  相似文献
