Choice Modelling Approaches: A Superior Alternative for Environmental Valuatioin?

In this paper, we examine some popular 'choice modelling' approaches to environmental valuation, which can be considered as alternatives to more familiar valuation techniques based on stated preferences such as the contingent valuation method. A number of choice modelling methods are consistent with consumer theory, and its focus on an attribute‐based theory of value permits a superior representation of many environmental management contexts. However, choice modelling surveys can place a severe cognitive burden upon respondents and induce satisficing rather than maximising behavioural patterns. In this framework, we seek to identify the best available choice modelling alternative and investigate its potential to 'solve' some of the major biases associated with standard contingent valuation. We then discuss its use in the light of policy appraisal needs within the EU. An application to the demand for rock climbing in Scotland is provided as an illustration.     

Evaluation of inventory management: Efficiency can affect success

In many manufacturing companies, top management analyzes inventories only when financial trouble is at hand. The average amount of money committed to inventories is about three times the amount held in cash. It is rare that a member of top management gives the sustained attention to inventories that he gives to the company's cash position. A troubled company can take important steps in retrenching by evaluating its inventory management. However, this evaluation can be a part of the continuing analysis of the company's operations, in most cases as an outgrowth of auditing services. The resulting efficiencies can have a favorable effect on the company's success and growth—especially if money formerly tied up in inventories is freed for investment in other resources.     

Anonymity and continuous social choice

Continuity of social choice is reformulated in terms of the quotient topology on profiles of individual preferences induced by the equivalence class corresponding to anonymity. It is shown that Chichilnisky's impossibility continues to hold.     

Leading global teams

Global teams that are characterized by national, cultural and linguistic heterogeneity and operate in a globally dispersed virtual environment are becoming an established form of organizing work in multinational organizations. As global team leadership research is rather limited, we review the literature on leading multicultural and virtual teams in a global context, focusing on leadership competencies, styles, strategies and modes. We also examine the emergent concepts of biculturalism, global mindset and cultural intelligence with respect to team leaders. Our aim is to add to our knowledge of leading global teams, highlight recent trends and suggest directions for future research. Three themes for global team leadership emerged: leaders as boundary spanners, bridge makers and blenders; people-oriented leadership; and leveraging diversity. We discuss implications for research and practice.     

Analysis of ultra-high-frequency financial data using advanced Fourier transforms

This paper presents a novel application of advanced methods from Fourier analysis to the study of ultra-high-frequency financial data. The use of Lomb–Scargle Fourier transform, provides a robust framework to take into account the irregular spacing in time, minimising the computational effort. Likewise, it avoids complex model specifications (e.g. ACD or intensity models) or resorting to traditional methods, such as (linear or cubic) interpolation and regular resampling, which not only cause artifacts in the data and loss of information, but also lead to the generation and use of spurious information.     

Contingent Valuation Versus Choice Experiments: Estimating the Benefits of Environmentally Sensitive Areas in Scotland

This paper reports results from a study of the economic value of the conservation benefits of Environmentally Sensitive Areas (ESAs) in Scotland. The main novelty of the approach taken is in comparing two direct valuation methods, namely contingent valuation and choice experiments, to value these benefits. The Contingent Valuation Method (CVM) is well-established as a technique for valuing the sorts of landscape and wildlife enhancements associated with ESAs. The CVM experiment reported here uses a dichotomous choice format, and includes a new correction for part-whole bias. Choice experiments are much less used as an environmental valuation technique. We note several advantages of such experiments over CVM, and then report characteristic values and ‘programme values’ estimated using the method. This application brings to light some problems in applying the choice experiment method. Finally, we discuss the issue of benefits transfer in the context of these two approaches to valuation.     

Reactions of the London Stock Exchange to Company Trading Statement Announcements

Using event study methodology, we examine market reactions to nearly 2,000 trading statements during the period 1995‐2001. We find that profit warnings outnumber upgrades by 50%, and, in line with previous US studies, we find that market reaction to the actual announcements is considerably greater for profit warnings than for upgrades.Sub-samples demonstrate significant market reaction to profit warnings for all sizecontrolled portfolios, but that reaction to the announcements is greatest for small companies.Examination of pre- and post-announcement CARs shows no pre-announcement market anticipation of the announcements.Post-announcement there is a significant positive abnormal return on the day after the announcement of bad news for the small company subsample.Other post-announcement results are small and insignificant.Trading volume results are consistent with this picture. Finally, when the trading statements are examined for news on turnover and margin changes, we find that the market reaction to margin changes is greater than market reaction to turnover changes.     

Non‐union employee representation: exploring the riddle of managerial strategy

Utilising case‐study research in two organisations this article considers the strategy underpinning managerially imposed systems of non‐union employee representation. Drawing on Dundon and Gollan's ‘sensitising framework’, an interplay of external factors and internal dynamics is seen to prompt objectives that are both defensive (union avoidance) and proactive in nature (e.g. the legitimisation of change). The article suggests that such goals represent ‘rival logics of action’, the tensions unleashed being ultimately reflected in the ineffective functioning of the institutions under review.     

Measuring the relative importances of social responsibility components: A decision modeling approach

In this study, a decision modeling approach is used to measure the relative importances of four social responsibility components. When given information concerning the economic, legal, ethical and philanthropic activities of 16 hypothetical organizations, 159 junior and senior management students judged the social responsibility of these firms. The study used two types of analysis: first, a within-subject regression, then a between-subject ANOVA. Results showed ethical behavior to be most important in judging social responsibility; legal behavior was second, discretionary behavior third, and economic behavior was least important. In addition, all but one rater consistently applied the social responsibility components. The implications of these results and suggestions for future research are discussed. Barbara A.
