Do Investors Expect Mean Reversion in Asset Prices?

We investigate the existence and source of equilibrium mean reversion in UK non-financial and financial asset prices over the period 6 April, 1981, through 31 October, 1995. Our results indicate substantial expected transitory components in commodity and metals markets but report expected mean reversion for financial assets only at the near to maturity horizons. Implied cash flow yields appear to have a role in driving the mean reverting process particularly at short horizons while the role of interest rate movements varied across assets and across maturities. Our results reject the existence of a common risk premium across market term structures.     

Noise and the Trading Mechanism: the Case of SETS

On 20 October 1997 the London Stock Exchange introduced a new trading system called SETS. This system was to replace the dealer system SEAQ, which had been in operation since 1986. Using the iterative sum of squares test introduced by Inclan and Tiao (1994) , we investigate whether there was a change in the unconditional variance of opening and closing returns, at the time SETS was introduced. We show that for the FTSE‐100 stocks traded on SETS, on the days following its introduction, there was a widespread increase in the volatility of both opening and closing returns. However, no synchronous volatility changes were found to be associated with the FTSE‐100 index or FTSE‐250 stocks. We conclude therefore that the introduction of the SETS trading mechanism caused an increase in noise at the time the system was introduced.     

Marketing implications of the expected role of physicians in family decisions concerning the institutionalization of the elderly

This study investigates the decision to place a loved one in a nursing home, looking at the interaction between adult children and the elderly, and at the role expected to be played by physicians. Younger respondents and those without previous experience with decisions concerning the admittance of a loved one in a nursing home do not see the physician as playing an important role, whereas the elderly and those with experience do. Differences in perceptions by these two groups are explored and the marketing implications for healthcare providers are discussed. © 1995 John Wiley & Sons, Inc.     

Entering Eastern European markets : Lessons from Kmart

Kmart completed its purchase of 13 stores in the Czech Republic and Slovakia in May/June 1992. Using interviews conducted in June 1993 with directors of Kmart-Czech Republic and Slovakia and a vice director of its major Prague competitor, Kotva, this paper analyzes the strategies Kmart is using to position itself in Eastern Europe for both retail sales and product acquisition and distribution. Four lessons to be learned from Kmart were identified: (1) internationalize what you do well; (2) know your customers by listening to them and adapting to their needs; (3) be flexible and change if a strategy does not work; and (4) balance short-and long-term gains.     

Book Reviews

This study applies data envelopment analysis to evaluate the financial efficiency of a sample of 63 top US pharmaceutical advertisers, based on their sales and media advertising expenditures in 11 key media outlets (i.e. network TV, cable TV, syndicated TV, spot TV, magazines, Sunday magazines, national newspapers, newspapers, network radio, national spot radio, and outdoor). The analyses reveal that, on average, 35% of a pharmaceutical advertising budget is wasted, the largest portion of which is on network TV. In addition, the results of tobit regression indicate that magazines and Sunday magazines significantly contribute to the advertising inefficiency.     

Evaluating the validity of self-assessment: measuring computer literacy among entry-level undergraduates within accounting degree programmes at two UK universities

This paper considers the validity of using self-assessment to measure computer literacy among entry-level undergraduate accounting students. Data collected from objective and self-appraisal computer literacy tests completed by students at two UK universities are analysed and the results of the tests compared for each student. The findings reveal significant differences in the students' perceived and actual computer literacy with the vast majority over-estimating their computer knowledge. Furthermore, evidence is provided that more-able students are more accurate in their self-assessment. These findings indicate that self-assessment is not an appropriate means of determining computer literacy among entry-level undergraduate accounting students when used in isolation. However, as an adjunct to a more robust measure of computer literacy, self-assessment may provide a useful insight into students' attitudes to computing. In addition, self-assessment stimulates reflection and thereby contributes to lifelong learning, a concept particularly important for accountants who must assess their competence throughout their professional careers.
