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

Rudy Moenaert, William Souder, Arnoud De Meyer, and Dirk Deschoolmeester report the results of their study of forty technologically innovative Belgian companies to examine the interaction between marketing and R&D. They studied one commercially successful and one commercially unsuccessful technological product innovation project in each participating company and collected data from one marketing and one R&D respondent per project. Communication flows between marketing and R&D are increased under conditions involving formalization of projects, decentralization, positive interfunctional climate, and role flexibility.  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

A study of the effect of age and gender upon student business ethics   总被引:1,自引:0,他引:1  
The present survey was voluntarily and anonymously completed by 2,196 students enrolled in business courses at the University of Southern Mississippi. The intent of the survey was to determine whether or not age or gender played a role in a person's perception of proper ethical conduct.The findings suggests that gender is a significant factor in the determination of ethical conduct and that females are more ethical than males in their perception of business ethical situations.Students were divided into groups according to age as follows: under 21 years, 22–30 years, 31–40 years, and 40 plus years. The results of this survey also suggest that age is a determining factor in making ethical decisions. The statistics suggest that those students falling in the 40 plus years age group were the most ethical, followed in order by the 31–40 group, the 22–30 group and those of 21 years of age and under.Durwood Ruegger is currently an Associate Professor of Finance and General Business at the University of Southern Mississippi.

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

This paper discusses the revolutionary new right introduced by the Trade Union Reform and Employment Rights Act 1993 for consumers to seek a court order to halt unlawful industrial action which disrupts the supply of goods or services, regardless of whether they have any enforceable right to the goods or services in question. Even more unusually, public funding is available to conduct these proceedings irrespective of the applicant's means where the industrial action is organised by a trade union. The paper analyses the nature of the right, locates it within the broader framework of remedies for the non-provision or inadequate provision of goods or services, and assesses the wider implications of the right for consumer policy.  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
