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

Models for which the MLE and the conditional MLE coincide   总被引:1,自引:0,他引:1  
The MLE, CMLE and MMLE coincide in a linear regression model with fixed individual effects. In this case, there is no incidental parameters problem and the MLE is consistent. The equivalence of these estimators is important because CMLE=MLE implies both the consistency of the MLE and the efficiency of the CMLE. In general, we cannot expect to find a CMLE or MMLE, since there may be no fixed-dimension sufficient statistic for the effects, nor an appropriate transformation of the data whose distribution does not depend on the effects. However, we show that the MLE, CMLE and MMLE do coincide in systems of seemingly unrelated regressions and in systems of simultaneous equations. We establish this result for systems in which (exogenous) variables in addition to (or other than) the intercept may have coefficients which vary over individuals, provided that the set of such variables is the same in every equation.The financial support of the National Science Foundation is gratefully acknowledged.  相似文献

This paper reviews the measurement of equilibrium unemployment in Australia using the Phillips curve. To provide a theoretical framework through which these measurement exercises can be understood, the theory of equilibrium unemployment based on wage bargaining is also described and reviewed. The paper shows how studies have moved from specifying a unique and constant equilibrium rate of unemployment to specifications which emphasise the influence of unemployment benefits, hysteresis and a range of equilibrium rates of unemployment.  相似文献

At some stage in every household's family life cycle, the household is likely to make certain decisions with regard to its housing environment. Although the household's housing decisions essentially comprise the decision to move, and the selection of a new residence, the process from which these decisions are derived is very complex because varying circumstances could produce a multitude of different housing decisions. Due to the sheer complexity of the household's housing decision–making process, researchers have generally focused on individual decision–making stages rather than on the process as a whole. This paper therefore attempts to conceptualize the entire household housing decision–making process using theoretical concepts from the economic perspective, and then tests the conceptual model with empirical evidence drawn from the moving population within the multi–racial society in Singapore.  相似文献
