Corporate Governance as Part of the Strategic Process: Rethinking the Role of the Board

Commercial food health branding is a challenging branch of marketing because it might, at the same time, promote healthy living and be commercially viable. However, the power to influence individuals’ health behavior and overall health status makes it crucial for marketing professionals to take into account the ethical dimensions of health branding: this article presents a conceptual analysis of potential ethical problems in health branding. The analysis focuses on ethical concerns related to the application of three health brand elements (functional claims, process claims, and health symbols) as well as a number of general concerns that apply to health branding as such. Being a pioneering analysis, this article advances the academic understanding of health branding and provides practitioners with knowledge of important concerns to take into account when marketing health brands.     

Exploring the use of travel information – identifying contextual market segmentation in Seoul, Korea

As the amount of information is rapidly growing, and ubiquitous urban environments are emerging, the question which kind of information to provide is a major challenge for commercial and public travel-information service providers alike. This paper reports the analyses of recent data, collected in Metropolitan Seoul, about the acquisition of travel information. The study applies CHAID analysis to find homogeneous segments in travel information acquisition. Findings indicate that contextual variables are crucial to explain information acquisition behaviour, depending on decision context. The implication is that both socioeconomic and contextual variables are important to better understand the acquisition (and provision) of travel information. The results have important implications for managers and policy-makers, in particular in the way they respond to dynamic, contextual market segmentation.     

Localism and the Big Society: the asset transfer of leisure centres and libraries – fighting closures or empowering communities?

This paper critically examines the ‘asset transfer’ of leisure services from the public to the voluntary sector. Asset transfer might be theorised as ‘austerity localism’, in which volunteers are obliged to fill the gaps left by retreating public provision, or as ‘progressive localism’, which represents new opportunities through the localism and Big Society agendas to develop more locally responsive, cooperative and mutualist visions. In this way, asset transfer might overcome the limitations of the United Kingdom policies in which ‘Big Government’ is replaced by civic society. Drawing on qualitative interviews with key personnel (volunteers, managers and local authority officers) at 12 leisure facilities, a grounded assessment of the nuanced balance between ‘austerity localism’ and ‘progressive localism’ is provided, including three observations. First, the main impetus for transfer was cuts in local authority budgets which stimulated the emergence of local groups of volunteers. Secondly, the transfers themselves required interaction between local government and the volunteer groups; however, the nature of the relationship and support given varied and support was limited by austerity measures. Thirdly, volunteers do not automatically fill a gap left by the state: without support transfer viability relies on the financial and social capital among volunteer groups, and this is unevenly distributed. These findings suggest that the capacity for a ‘progressive localism’ to emerge through asset transfer is limited. However, where transfer has occurred, there are some progressive benefits of volunteer empowerment and a more flexible service.     

Die Private Krankenversicherung im Fokus des Verfassungsrechts

Starting with the question as to the extent to which the state may interfere with economic interests at all, a brief historical overview is given through to the regulations currently in force. The Basic Law (Grundgesetz) remains neutral on this issue so that the question cannot be discussed as to whether regulations are at all conceivable and admissible but how far these can go. The noteworthy parameters of the German law on intensifying competition in the statutory health insurance system (GKV-WSG) are then highlighted: the collision of the reform of private health insurance law with the reform of the entire insurance contract law as well as the length of the individual provisions and the correlating remark of member of parliament Merz in the Cicero magazine according to which no single member of parliament had even a rudimentary understanding of he was actually deciding on. From the point of view of substantive law, the main “diseases” of the GKV-WSG are strikingly shown, including in particular the creation and design of the basic rate as well as non-terminability etc. Finally reference is made to the double balancing act with which the private health insurance system is confronted: on the one hand the statutory health insurance system with its allocation principle and the private health insurance system with it superior principle of equivalence that wakens the desires of 4/5 of the German population who live in a poorly functioning system; on the other hand the field of tension between individual and collective consumer protection, i.e. between the high standards which are to be created for individuals which are then ultimately to be borne by the collective.     

Ridge regression and its degrees of freedom

For ridge regression the degrees of freedom are commonly calculated by the trace of the matrix that transforms the vector of observations on the dependent variable into the ridge regression estimate of its expected value. For a fixed ridge parameter this is unobjectionable. When the ridge parameter is optimized on the same data, by minimization of the generalized cross validation criterion or Mallows \(\hbox {C}_{L}\) , additional degrees of freedom are used however. We give formulae that take this into account. This allows of a proper assessment of ridge regression in competitions for the best predictor.     

A Comment on Dehez and Tellone, “Data games: sharing public goods with exclusion”

This comment shows that the data cost game introduced in Dehez and Tellone (Journal of Public Economic Theory, 2013) coincides with the nonadditive component of the library cost game studied in Driessen, Khmelnitskaya, and Sales (TOP, 2012) where the core, nucleolus, and Shapley value were also investigated.     

Through Trial and Error to Collusion*

In this article we study a very simple trial and error learning process in the context of a Cournot oligopoly. Without any knowledge of the payoff functions players increase, respectively decrease, their quantity as long as this leads to higher profits. We show that despite the absence of any coordination or punishing device this process converges to the joint‐profit‐maximizing outcome.     

Tail dependence between gold and sectorial stocks in China: perspectives for portfolio diversification

This article analyzes the relationship between gold quoted on the Shanghai Gold Exchange and Chinese sectorial stocks from 2009 to 2015. Using different copulas, our results show that there is weak but significant tail dependence between gold and Chinese sectorial stock returns. This means that the dependence between extreme movements of the two assets is not pronounced and confirms the role of gold as a safe haven asset. Based on analyzing the efficient frontier, CCC-GARCH optimal weights, hedge ratios and hedging effectiveness, we further show that adding gold into Chinese stock portfolios can help to reduce their risk. Gold appears to be the most efficient diversifier for stocks of the materials sector and the less efficient for the utilities sector. As a robustness check, we also compare gold to oil and indicate that gold is more efficient than oil in the diversification of Chinese stock portfolios.

     

Equally important criteria and demanding aggregation

Within the class of weighted averages of ordered measurements on criteria of ‘equal importance’, we discuss aggregators that help assess to what extent ‘most’ criteria are satisfied, or a ‘good performance across the board’ is attained. All aggregators discussed are compromises between the simple mean and the very demanding minimum score. The weights of the aggregators are described in terms of the convex polytopes as induced by the characteristics of the aggregators, such as concavity. We take the barycentres of the polytopes as representative weights.
