A note on the determination of A-optimal type block designs under fixed and mixed effects models

In this paper, we consider the problem of estimating a selected set of contrasts between v treatments using a block design consisting of b blocks of size k. Traditionally, the construction of A-optimal block designs for such situations has been carried out assuming a fixed effects model. In this paper, we show that A-optimal designs constructed under a fixed effects model are robust in the sense that these designs have maximal minimal efficiency when considered among all available designs and under all possible mixed effects models.

The evolution of consumer knowledge and sources of information: Hungary in transition

The authors’ research in Hungary during the period of transition to a market economy provides an opportunity to examine the evolving relationships between consumer product knowledge and its antecedents, including advertising, personal search, interpersonal sources, and brand experience. Their findings, based on survey data collected in Budapest in 1992 and 1998, indicate that the market information variables explain more variance in consumer knowledge later rather than earlier in the transition. Advertising is an important predictor of consumer knowledge later but not earlier in the transition, personal search is important at both times, and interpersonal sources are not important in either time period; brand experience is negatively related to knowledge earlier in the transition and positively related later in the transition. This study allows one to begin to understand the boundary conditions associated with studies conducted in developed economies. Managerial implications for firms investing in transitional economies are presented. Robin A.

Risk,commitment, and project abandonment

This article deals briefly with the most loathsome of business topics — the admission of failure. Rather than actively encouraging project Anti-champions, many organizations experiencing financial duress inadverdently stifle opposing opinion. In some cases recognition is delayed until it is too late. This is unfortunate since failure can be managed like any other business situation. Companies with CEOs that foster open communications between finance and operations are more likely to avoid escalating commitment to failed projects.Prudence is a rich, ugly old maid courted by incapacity.

Modeling Disinterest and Dislike: A Bounded Bayesian Mixed Logit Model of the UK Market for GM Food

Mixed logit models represent a powerful discrete choice analytical model but require assumptions about the functional form of the parameter distributions. The use of unbounded distributions, such as the normal distribution, may be regarded as unsuitable where theory indicates that all are negatively affected by increases in an attribute, such as price. Bounded distributions such as the triangular and log-normal are unable to model the case where a section of the population is indifferent towards an attribute, while the remainder are negatively disposed toward it. Train and Sonnier’s bounded mixed logit model accommodates these features and is employed in this paper. A censored normal and Johnson’s S_b distribution are used to model preferences in the UK for food attributes, including price and GM technology. Bi-modal distributions are identified regarding GM food: some are unlikely to ever consume it, some are close to indifference and willing to consume at relatively small discounts while the remainder are fairly unresponsive to further price reductions.     

The demand for game day attendance in college football: an analysis of the 1997 Division 1‐A season

This paper develops a predictive model which includes game, team and university specific factors that are likely to influence game day demand for Division 1‐A college football. Attendance during the 1997 regular season is used as the dependent variable. Tobit estimates of two separate equations reveal that the quality of both teams, traditional rivalry and membership of specific conferences have a significant influence on demand. In addition, colleges with lower enrollments and a higher percentage of off‐campus students attract smaller crowds. The presence of a nearby professional football team also detracts from a college team's drawing power. Copyright © 2003 John Wiley & Sons, Ltd.     

The Japanisation of British industry? Instances from a high growth area

Here the authors make two arguments, Japanese industry is characterised by distinctive practices, but these predominate in only certain ‘leading edge’ sectors and were introduced mainly to ensure labour supply. Second, Britain's managers are increasingly outside the internal labour markets of large corporations. In this respect British firms are not becoming ‘Japanese’.     

The impact of (more) enlargement on the European Employment Strategy

The European Union (EU) aspires to be the most competitive, full employment economy in the world and has set a number of ambitious targets to be met by 2010 in order that it can achieve this goal. At the same time, it is pursuing an enlargement policy that will witness the accession of an increasing number of less developed nations. This article explores some of the tensions that exist between these two goals as these are manifest in labour market indicators and finds the likelihood of meeting the deadline set for success remote.     

Family Firms

We present a model of succession in a firm owned and managed by its founder. The founder decides between hiring a professional manager or leaving management to his heir, as well as on what fraction of the company to float on the stock exchange. We assume that a professional is a better manager than the heir, and describe how the founder's decision is shaped by the legal environment. This theory of separation of ownership from management includes the Anglo‐Saxon and the Continental European patterns of corporate governance as special cases, and generates additional empirical predictions consistent with cross‐country evidence.     

关于铁矿产品合理价位的研究与建议

铁矿石是钢铁工业的重要原料,其价格一方面伴随钢铁产品价格升降同时起伏,另一方面其供求状况又对钢铁产品价格的变化起着重要的制约作用。所以,研究铁矿产品合理价位,保持市场供应相对稳定,不仅对保持矿山企业可持续发展具有重要作用,同时,也是稳定钢铁工业原料供应,维护钢铁产品合理价位和市场稳定的基础,值得认真研究。因此,冶金价格协会、冶金矿山价格研究会、《冶金财会》编辑部组织专家、学者和矿山实际工作者组成联合调研组,对这个问题进行了专题研究,现将研究结果报告如下。一、建国以来我国铁矿产品价格变动的基本情况建国50多年来…
