The realized volatility of FTSE‐100 futures prices

Five‐minute returns from FTSE‐100 index futures contracts are used to obtain accurate estimates of daily index volatility from January 1986 to December 1998. These realized volatility measures are used to obtain inferences about the distributional and autocorrelation properties of FTSE‐100 volatility. The distribution of volatility measured daily is similar to lognormal while the volatility time series has persistent positive autocorrelation that displays long‐memory effects. The distribution of daily returns standardized using the measures of realized volatility is shown to be close to normal, unlike the unconditional distribution. © 2002 Wiley Periodicals, Inc.

An empirical model of the multi‐unit,sequential, clock auction

We construct a model of participation and bidding at multi‐unit, sequential, clock auctions when bidders have multi‐unit demand. We describe conditions sufficient to characterize a symmetric, perfect‐Bayesian equilibrium and then demonstrate that this equilibrium induces an efficient allocation. We propose an algorithm, based on the generalized Vickrey auction, to calculate the expected winning bid for each unit sold. This algorithm allows us to construct a simulation‐based estimator of the parameters for both the participation process and the distribution of latent valuations. We apply our method to data from 37 multi‐lot, sequential, English auctions of export permits for timber held in Russia. Copyright © 2006 John Wiley & Sons, Ltd.     

Not-So-Strong Evidence for Gender Differences in Risk Taking

Based on a growing body of experimental and other studies, two recent economics survey articles claim to find “strong evidence” that women are “fundamental[ly]” more risk-averse than men. Yet, much of the literature fails to clearly distinguish between differences that hold at the individual level (categorical differences between men and women) and patterns that appear only at the aggregate level (statistically detectable differences in men's and women's distributions, such as different means). There is a resulting problem of possible misinterpretation, as well as a dearth of appropriate attention to substantive significance. Additionally, one of the two surveys suffers from problems of statistical validity, possibly due to confirmation bias. Applying appropriate, expanded statistical techniques to the same data, this study finds substantial similarity and overlap between the distributions of men and women in risk taking, and a difference in means that is not substantively large.     

Marketing research interviewers and their perceived necessity of moral compromise

Marketing research interviewers often feel that they must compromise their own moral principles while executing work-related activities. This finding is based on analysis of data obtained from three focus group interviews and a mail survey of 173 telephone survey interviewers. Data from the mail survey were used to construct scales measuring interviewers' perceived necessity of moral compromise, moral character, and job satisfaction. The three scales then were used in a hierarchical regression analysis to predict incidences of interviewers' self-reported proscribed behaviors on the job, the latter being an index of behaviors known by interviewers to be wrong. Results support all hypothesized relationships. James E. Nelson is Associate Professor of Marketing at the University of Colorado at Boulder.

Business Ethics – to Teach Or Not to Teach?

While some studies have explored the effects of taking business ethics classes on business students, several shortcomings in them invite greater scrutiny of this critical issue (cf. Robertson, 1993). In contrast to previous research, this study more directly assesses the impact of taking business ethics class on ethical decisions made by future business executives. To determine if teaching business ethics modifies behaviors or behavioral intentions, the current study examines decisions made in ethical situations rather than inferring the same by measuring attitudes, values, etc. Furthermore, these were measured in three different business contexts: whistle blowing, recruitment, and industrial espionage, to enhance the generalizability of the findings. Finally, unlike most previous studies, a within-subject's design was chosen to eliminate confounds that may be caused by not controlling for individual differences (Glenn, 1992). The current results indicate that business ethics classes have minimal effect on ethical decision making in any of the three contexts investigated, empirically providing support for Wolfe's (1993) and Wynd and Mager's (1989) position that teaching business ethics may have limited benefits.     

The All-Important First and Last Impression: A Guide to Auditing the Trip to and from Your Airport

The first and last impressions of a destination are critical to the guest experience. This article details a protocol to systematically analyze what guests experience as they enter and leave a destination via the airports. The article pulls from the author's experience researching for, and participating in, such an audit of the Philadelphia International Airport on behalf of the State of Delaware and includes a convenient list of points to be assessed in an audit.     

Do Labour Strategies Matter? An Analysis of Two Enterprise-Level Data Sets in China

This paper examines the effect of labour strategies and management types on firm performance in Chinese enterprises. We use two large panel surveys on Chinese enterprises, spanning almost two decades of transition. Our findings suggest that, as commonly thought, there are significant differences across ownership types in China in the degree to which flexible labour market strategies are utilized; and more flexible strategies (such as bonus-reward systems) do seem to significantly enhance performance. However, after controlling for different degrees of labour market flexibility, ownership differences have little influence on enterprise performance (with the exception that foreign joint ventures clearly outperform other types in growth and labour productivity). This important result suggests that the impact of Chinese ownership types on performance is felt through cost-impacts rather than via direct differences in competitive behaviour or the goals of enterprise decision-makers.     

Demand,innovation, and the dynamics of market structure: The role of experimental users and diverse preferences

The history of a number of industries is marked by a succession of eras, associated with different dominant technologies. Within any era, industry concentration tends to grow. Particular eras are broken by the introduction of a new technology which, while initially inferior to the established one in the prominent uses, has the potential to become competitive. In many case new entrants survive and grow, and the large established firms do not make the transition. In other cases, the established firms are able to switch over effectively, and compete in the new era. This paper explores a model which generates this pattern and has focused on the characteristics of the demand. We argue that the ability of the new firms exploring the new technology to survive long enough to get that technology effectively launched depends on the existence of fringe markets which the old technology does not serve well, or experimental users, or both. Established firms initially have little incentive to adopt the new technology, which initially is inferior to the technology they have mastered. New firms generally cannot survive in head-to-head conflict with established firms on the market well served by the latter. The new firms need to find a market that keeps them alive long enough so that they can develop the new technology to a point where it is competitive on the main market. Niche markets, or experimental users, can provide that space.

European integration: the third step

A perception of declining EU competitiveness has intensified calls for structural reforms within the EU. This paper examines recent evidence on changes in relative EU competitiveness and considers the observed changes in relation to the evolving competitive environment facing EU firms. Our analysis suggests that recent declines in EU competitiveness reflect changes (or lack thereof) within the EU in response to an evolutionary “Third Step” in the process of EU integration: global market integration. Starting from the mid-1990s, we find that the EU began to face unprecedented increases in external sources of competition. The rising competition from external sources and declining export market competitiveness created pressures for EU firms to alter their organizational and product market strategies to meet the challenge of a globally integrating market. While many leading EU firms have responded to this challenge, most EU firms remain hampered by anachronistic EU product and labor market regulations that have inhibited adjustments that could better restore the competitiveness of EU based firms. In particular, our analysis points to labor market rigidities and limited growth in the services sector as factors limiting adjustment to the realities of a global market. The growing calls for structural reforms therefore reflect the rising external competitive pressures on EU firms as they attempt to respond to growing global competition.
