Consumer perceptions of risks of chemical and microbiological contaminants associated with food chains: a cross-national study

The development and implementation of effective systems to identify vulnerabilities in food chains to chemical and microbiological contaminants must take account of consumer priorities and preferences. The present investigation attempted to understand consumer perceptions associated with chemical and microbiological contaminants in four specific food chains (drinking water, farmed salmon, chicken and milk powder). To this end, ten focus group discussions were held in five different countries (Poland, Ireland, the Netherlands, France and Brazil). Consumers expressed higher concerns about chemical, as compared with microbial, contaminants. Chemical contaminants were more strongly associated with the potential for severe consequences, long-term effects and lack of personal control. Traceability was considered by consumers as a useful tool that offers the potential to improve consumer confidence in food safety.     

To challenge the world view or to flow with it? Teaching sustainable development in business schools

This paper explores the fundamental question of what ‘responsibility’ means to different sets of world views adopted implicitly by business students. The exploration adopts the stakeholder theory and three subsets of the Friedman mentality to explain how individuals may value sustainability initiatives. Subsequently, it explores whether it is better to flow with the dominant economic‐driven world view as prescribed by the business school or to challenge it in order to cultivate business students with sustainability‐driven values. The conclusion highlights implications for business and management education, as well as the role of entrepreneurship to promote sustainability values.     

Capital-induced labor migration in a spatial Solow model

Journal of Economics - In this work we consider labor mobility in the spatial Solow model for economic growth. Besides considering that labor diffuses from regions with higher density to regions...     

Market illiquidity and bounds on European option prices

The paper analyses the impact of illiquidity of a stock paying no dividends on the pricing of European options written on that stock. In particular, it is shown how illiquidity generates price bounds on an option on this stock, even in the absence of other imperfections, such as transaction costs and trading constraints, or the assumption of stochastic volatility. Moreover, price bounds are shown to be asymmetric with respect to the option price under perfect liquidity. This fact explains, under some conditions, the appearance of a smile effect when the implied volatility is estimated from the mid-quote.     

Rational Underdevelopment*

We propose a two‐region two‐sector model of uneven development, where technological change benefits either the lagging or the leading region. In this framework interregional transfers may lead to persistent underdevelopment; by raising wages, transfers reduce the chance of the backward region adopting a new technology and taking off. Due to uncertainty about which region benefits from technological change, the backward region may rationally choose to remain underdeveloped, while the advanced region continues to pay transfers. The model provides a rationale for cases, such as Italy's Mezzogiorno, where the same rich region subsidizes the same poor region on a continuous basis.     

Changing Women's Lives: Child Care Policy in Ireland

Child care as a policy issue has been forced to the center of the national planning agenda in Ireland with the report of an expert working group on child care. As Ireland has broken into the ranks of wealthy Western economies, Irish women have joined the formal workforce in ever greater numbers, dramatically breaking the traditional ideology of women as childbearers and homemakers. However, women are now carrying the double burden of work that accompanies the lack of any state policy on child care. This article traces this recent history of the feminizing of the Irish workforce, amidst a fast-changing social context for family life, and the multiple problems confronting the expert working group of securing an adequate range of policies for the provision of child care in a country which has one of the lowest rates of formal state provision in the entire European Union.     

ASYMMETRIC INFORMATION AND EXCHANGE OF INFORMATION ABOUT PRODUCT DIFFERENTIATION

We introduce asymmetric information about consumers’ transportation costs (i.e., the degree of product differentiation) in the model of Hotelling. When transportation costs are high, both firms have lower profits with asymmetric information than with perfect information. Contrarily, if transportation costs are low, both firms may prefer the asymmetric information scenario (the informed firm always prefers the informational advantage, while the uninformed firm may or may not prefer to remain uninformed). Information exchange is ex‐ante advantageous for both firms, but ex‐post damaging if transportation costs turn out to be low. If the information is unverifiable, the informed firm does not represent a reliable source of information, since it always prefers to announce that transportation costs are high and there is no contract that induces truthful revelation.     

Improving Service Quality in Person-to-Person Encounters: Integrating Findings from a Multi-disciplinary Review

Although the core of most services is a person-to-person encounter, we still know very little about its underlying mechanisms as very few models or theories have been developed for these dynamic interactions between persons. An holistic approach to quality improvement is therefore suggested. Different prototypical person-to-person encounters may be studied on different levels and interfaces in service operations to eliminate inconsistencies. The aim of this contribution is to review some recent research findings for person-to-person encounters from the neighbouring management fields of services, operations and human resources in order to draw together their strategic implications for service managers. Some ontological and methodological considerations of studying person-to-person encounters from a qualitative perspective are discussed. The outline of a multi-disciplinary and learning-centred research approach is also suggested. Findings are integrated by a model of four generic and strategic processes for quality improvement in service operations. Finally, some implications for managers are proposed.
