Purpose – This paper seeks to examine whether the stakeholder strategy matrix provides useful guidance for managers in dealing with stakeholders. The matrix suggests that strategies for dealing with stakeholders can be determined based on stakeholder ability to cooperate and threaten organisational outcomes.

Design/methodology/approach – The study uses a hypothetical scenario looking at the development of a new environmentally friendly product, where eight stakeholder groups and their influencing abilities are manipulated. Marketers reviewed one version of the scenario and were then asked the applicability of 13 strategies for each stakeholder group described. Mixed design analysis is then undertaken to examine the direct effects and interactions between the four combinations of influencing abilities, the stakeholder group examined or how the strategy suggested impacted on managers' views.

Findings – The research found that there was an interaction effect suggesting that some strategies were more applicable to stakeholders with certain sets of influencing abilities, as the stakeholder strategy matrix suggested. The specific stakeholder group examined also appeared to impact on managers' views, which is inconsistent with the theory.

Research limitations/implications –
The limitations are that the research focused on managers' perceptions of the applicability of strategies, rather than the actual success of strategies examined. Research into the effectiveness of actual behaviours would possibly require more in-depth examination of case studies.

Practical implications – The research suggests that the stakeholder strategy matrix may provide some guidance as to how managers deal with stakeholders. However, it also suggests that managers may be implicitly applying influencing abilities to groups irrespective of their “true” influencing ability. In this case managers are in fact ignoring valuable information when deciding how to interact with stakeholders and therefore possibly using less effective strategies to interact with stakeholders.

Originality/value – The research is unique as it looks at determining whether different types of strategies for dealing with stakeholders are perceived to be more or less effective. This therefore seeks to make stakeholder theory more strategic and applicable in a broader set of contexts. As such the paper would be of interest to managers seeking to understand better how to deal with stakeholders and to theorists seeking to understand better how stakeholder theory impacts on organisational outcomes.

Purpose – The purpose of this article is to present an empirical analysis of complex sample data with regard to the biasing effect of non-independence of observations on standard error parameter estimates. Using field data structured in the form of repeated measurements it is to be shown, in a two-factor confirmatory factor analysis model, how the bias in SE can be derived when the non-independence is ignored.

Design/methodology/approach – Three estimation procedures are compared: normal asymptotic theory (maximum likelihood); non-parametric standard error estimation (naïve bootstrap); and sandwich (robust covariance matrix) estimation (pseudo-maximum likelihood).

Findings – The study reveals that, when using either normal asymptotic theory or non-parametric standard error estimation, the SE bias produced by the non-independence of observations can be noteworthy.

Research limitations/implications –
Considering the methodological constraints in employing field data, the three analyses examined must be interpreted independently and as a result taxonomic generalisations are limited. However, the study still provides “case study” evidence suggesting the existence of the relationship between non-independence of observations and standard error bias estimates.

Originality/value – Given the increasing popularity of structural equation models in the social sciences and in particular in the marketing discipline, the paper provides a theoretical and practical insight into how to treat repeated measures and clustered data in general, adding to previous methodological research. Some conclusions and suggestions for researchers who make use of partial least squares modelling are also drawn.

In this paper we examine the role of environmental quality in determining per capita health expenditures. We take a panel cointegration approach in order to explore the possibility of estimating both short-run and long-run impacts of environmental quality. Our empirical analysis is based on eight OECD countries, namely Austria, Denmark, Iceland, Ireland, Norway, Spain, Switzerland, and the UK for the period 1980–1999. We find that per capita health expenditure, per capita income, carbon monoxide emissions, sulphur oxide emissions and nitrogen oxide emissions are panel cointegrated. While short-run elasticities reveal that income and carbon monoxide emissions exert a statistically significant positive effect on health expenditures, in the long-run in addition to income and carbon monoxide, we find that sulphur oxide emissions have a statistically significant positive impact on health expenditures.

This study investigates the use of strategy to address changes in business performance. It suggests the use of the marketing audit as a facility that can assist with the establishment, maintenance, and management of a market orientation strategy. The practice of the marketing audit and its perceived benefits are examined, and their relationships with change in business performance are investigated. The results indicate a positive association between the usage of the marketing audit and increase in market share, and a stronger increase in market share than increase in overall financial performance.

In this paper we explore the extent of exchange rate pass-through for the USA, UK and Japan using a post-Bretton Woods industry-level dataset. We investigate how different channels of exchange rate pass-through affect domestic and import prices. Our analysis is suggestive of two channels of transmission and we find considerable variation in the extent of pass-through across industries and countries.

We examine the trading activities of directors in shares of their own companies on the Australian Stock Exchange during the July-December 2005 period. We find that directors of small companies in particular earn abnormal return after both their 'Purchase' and as well as their 'Sale' trade. Directors of these companies have an uncanny ability to time the market by trading when mispricing is greatest, and are able to predict the future performance of their firms in short run. For directors of medium and large companies, we find evidence that 'Sale' trades are the ones which work as loss avoiders. Outsiders recognise to some extent that directors' trades are informative, however they are slow to incorporate the new information into prices, refuting much of the market efficiency literature.

We examined associations between objective measures of the local road environment and physical activity (including active transport) among youth. There is little empirical evidence of the impact of the road environment on physical activity among children/adolescents in their neighborhoods. Most recent studies have examined perceptions rather than objective measures of the road environment. This was a cross-sectional study of children aged 8–9 years (n = 188) and adolescents aged 13–15 years (n  = 346) who were participants in the 3-year follow-up of the Children Living in Active Neighborhoods (CLAN) longitudinal study in Melbourne, Australia. At baseline (2001), they were recruited from 19 state primary schools in areas of varying socioeconomic status across Melbourne. Habitual walking/cycling to local destinations was parent-reported for children and self-reported for adolescents, while moderate-to-vigorous physical activity (MVPA) outside school hours was recorded using accelerometers. Road environment features in each participant’s neighborhood (area of radius 800 m around the home) were measured objectively using a geographical information system. Regression analyses found no associations between road environment variables and children’s likelihood of making at least seven walking/cycling trips per week to neighborhood destinations. Adolescent girls residing in neighborhoods with two to three traffic/pedestrian lights were more likely to make seven or more walking/cycling trips per week as those whose neighborhoods had fewer traffic lights (OR: 2.7; 95% CI: 1.2–6.2). For adolescent boys, residing on a cul-de-sac, compared with a through road, was associated with increases in MVPA of 9 min after school, 5 min in the evenings, and 22 min on weekend days. Speed humps were positively associated with adolescent boys’ MVPA during evenings. The road environment influences physical activity among youth in different ways, according to age group, sex and type of physical activity.
