Uncertain spatial demand and price flexibility: A state space approach to duopoly

Sufficient conditions for a unique price equilibrium, in terms of the uncertainty distribution and the state contingent consumer distributions, are given for spatial duopoly. Also considered are efficiency and endogenous locations for the symmetric case and comparative statics on price flexibility.     

Public perceptions of food-related risks: a cross-national investigation of individual and contextual influences

Public concerns about food risks have grown in recent decades in response to many food-related scandals. Despite some evidence that risk concerns vary across societies and risk domains, these variations remain understudied. To address this gap, this paper conducts a multi-level analysis of public concerns about biological and chemical/technical food risks in 26 European countries. Findings confirm previous work on individual predictors of risk concern and suggest that several contextual factors contribute to cross-national variations: aggregate perceptions of risks as unnatural, retail concentration in the food sector, and media coverage. The effect of institutional trust on risk concerns varies substantially across nations. Findings also reveal important differences in public concerns about biological versus chemical/technical food risks, supporting the view that food risk perception is multi-dimensional and complex.     

A Masterclass in interdisciplinarity: Research into practice in training the next generation of interdisciplinary researchers

This paper draws on evaluations of a number of interdisciplinary studentship and fellowship schemes to discuss some of the challenges of developing interdisciplinary research skills in early career researchers. It describes efforts to support such capacity-building in the UK through a series of Interdisciplinary Masterclasses which used workshop-based elicitation techniques to develop smallscale studies in order to synthesise experiential knowledge and foster mutual learning. This has enabled us to build important bridges between research and practice, thereby supporting and developing the interdisciplinary careers of early- and mid-career researchers, as well as research managers and leaders. This paper describes an approach to interdisciplinary capacity-building derived from actual practice. Based on learning from these activities, we offer some suggestions for improved supervision and mentoring of interdisciplinary graduate students and young postdoctoral researchers. If we are to develop effective, future interdisciplinary capacity, we advocate that supervisors/mentors need to focus, not just on the research, but on the particular forms of professional support and mentoring required by inexperienced interdisciplinary researchers in terms of career guidance, the development of publications strategies and network building.     

Two-part tariffs in the online gaming industry: The role of creative destruction and network externalities

Playing computer games online is a fast growing, billion dollar industry which has received little academic attention. The industry exhibits a number of interesting economic features. The industry structure is determined by creative destruction as in Aghion and Howitt (1992) [Aghion, P., Howitt, P. 1992. A model of growth through creative destruction, Econometrica, 60(2), 323–351], with game makers experiencing market power within a genre until the game is superceded. Furthermore, the attractiveness of playing a game online depends on the existence of opponents (positive network externalities) while technical and reputational problems eventually arise (negative network externalities). We model the choice of two-part tariffs by a monopolist under creative destruction and network externalities and derive conditions for the multiple equilibria which currently exist in the industry.     

University planning,decentralization and resource allocation

This paper proposes a system of resource allocation in universities which addresses both the problem of useful simulation of alternatives and efficient substitution of resources. It is the authors' view that the reasons why various university planning models proposed in the last few years have not been found useful in practice is that they take inadequate account of the decentralized nature of decisionmaking within universities. In this regard the three main points of the paper are: (1) university planning models should have flexible aggregation categories which can be determined and re-adjusted by the decisionmaker as he uses it; (2) resource constraints in university planning models should be flexible and negotiable, and negotiation over resources should be part of the analyst's domain of inquiry; (3) planning in universities must take into account the problem of introducing incentives which cause the behavior of individuals within the university to be directed to the needs of the institution's clienteles.     

Doing more with less: productivity or starvation? The Intellectual Asset Health Check

The recent wave of savings in public service expenditure comes at the risk of creating starved workplaces, depleted of intellectual assets. This paper examines the perils of starved workplaces and how to avoid them. Organizations that nurture their intellectual assets were found to outperform their peers with 13.3% higher productivity. These organizations created a ‘win–win situation’, achieving both productivity targets while sustaining high stocks of emotional and human capital.
