The link between diet and health: an exploratory study of adolescents in Northern Ireland using foodmaps

A significant proportion of consumers in the UK continue to adopt a diet consisting largely of nutritionally unbalanced foods. The adolescent period has been identified as being formative in the development of long‐term eating habits as the individual achieves greater control over their food choice. By examining the current eating behaviour of a sample of adolescents, the aim of this study was to establish why they are not utilizing their knowledge to choose nutritionally balanced foods. A two‐stage data collecting procedure was adopted. In stage 1, respondents (n = 136) completed a questionnaire that measured demographic and social factors, knowledge, attitudes, pre‐existing behaviour with respect to food and the influence of family, peers, the media and government campaigns on their eating behaviour. In stage 2, a subsection of the respondents (n = 20) completed a foodmap, which revealed the network of relationships involved in the adolescents' decision‐making process by identifying the links among the foods consumed, the people they eat with and the places they eat in. Results emphasized the importance of the home environment and the continuing influence of parents on adolescents' eating behaviour despite the greater independence related to this stage of the life cycle. A proportion of the sample was found to have recognized the need to change their eating behaviour in order to lose weight, because of their sporting commitments or to improve their health. Recommendations from this study include the need for the various agencies involved in the promotion of balanced dietary behaviour to attend to the link among adult, family and adolescent, and the need for greater progress in enabling consumers to translate the theory of nutritional education into practice.     

What Do Farmers Want From Agri‐Environmental Scheme Design? A Choice Experiment Approach

Agri‐environmental schemes (AES) have had a limited effect on European agriculture due to farmers’ reluctance to participate. Information on how farmers react when AES characteristics are modified can be an important input to the design of such policies. This article investigates farmers’ preferences for different design options in a specific AES aimed at encouraging nitrogen fixing crops in marginal dry‐land areas in Spain. We use a choice experiment survey conducted in two regions (Aragón and Andalusia). The analysis employs an error component random parameter logit model allowing for preference heterogeneity and correlation amongst the non‐status quo alternatives. Farmers show a strong preference for maintaining their current management strategies; however, significant savings in cost or increased participation can be obtained by modifying some AES attributes.     

Estimating Price Elasticities of Food Trade Functions: How Relevant is the CES‐based Gravity Approach?

The main objective of this article is to examine econometric estimates of price elasticities of food trade functions. We investigate the relevance of the prominent gravity approach. This approach is based on the assumptions of symmetric, monotone, homothetic, Constant Elasticity of Substitution (CES) preferences. We test all these assumptions using intra‐European trade in cheese. In general, the assumptions made on preferences by the gravity approach are not supported by our dataset. The bias induced in the estimated price elasticities is ambiguous.     

Participant‐focused analysis: explanatory power of the classic psychometric paradigm in risk perception

Typical psychometric paradigm factors appear to have greater explanatory power for individual participants than previously envisaged. It is possible to acquire interpretable information about single participants using two factors (catastrophic potential and social and personal exposure) from aggregated participant‐focused data. Our results suggest that the classical psychometric model originated by Fischhoff and Slovic in the early 1980s to explain differences among hazards may also be capable of accounting for differences among participants. While socio‐demographic conditions on their own do not have substantial explanatory power, they are statistically significant and appear to dictate the position of participants within the factor space obtained using a participant‐focused analysis. One of the principal criticisms of the psychometric paradigm has been its lack of interpretability when using disaggregated data, but incorporating socio‐demographic variables overcomes this limitation.     

The Pricing of Audit Services: Further Evidence from the Canadian Market

Since the seminal work of Simunic (1980), many studies have investigated audit pricing, competition in the audit industry, product differentiation and audit cost functions. This study expands on the work done to date by examining Canadian audit fees across time, audit firm and industry. The observations of audit fee data span the period of time during which the provincial codes of professional ethics with respect to fee tenders and advertising in general were relaxing in Canada. The results reported in this study support the existence of differentiated audit services in the Canadian audit market, and are consistent with DeAngelo's (1981) size interpretation of audit quality. Although no significant differences in the pricing of audit services across time are detected, the data provide evidence of significant pricing differences across (pre-merger) Big Eight audit firms in the small auditee market, suggesting that treating these audit firms as a homogeneous group in future research may not be appropriate. These inter-firm pricing differences do not appear to be due to the potential confounding effects of the auditee's industry. In contrast to previous studies, a significant positive association between internal and external audit costs is observed, suggesting a complementary, rather than a substitute, relationship.     

The influence of transformational leadership and organizational identification on intrapreneurship

Managers play a vital role in encouraging and supporting the initiatives of individual employees to explore new opportunities, to develop new products or to improve work procedures for the benefit of the organization. This study examines the influence of manager leadership styles on employee intrapreneurial behavior and the mediating role of organizational identification. Partial Least Squares modeling was used to analyze the data from 186 employees belonging to several Spanish public and private organizations. The results show that transformational leadership has a positive impact on employee intrapreneurial behavior, whereas transactional leadership negatively influences it. Furthermore, these effects are found to be partially mediated by organizational identification.     

The changing role of house price dynamics over the business cycle

In this paper, we attempt to analyse the relationship between house price dynamics and the business cycle. Employing a time-varying transition probability Markov switching framework, we provide empirical evidence that house price growth may prove a useful leading indicator for turning point detection. Focusing on three countries, the US, UK and Spain, we furthermore provide evidence that although potentially informative from an overall perspective in business cycle modelling, the significance of signals contained in house prices may not be symmetric across the identified high growth and low growth states. In addition, we suggest a possible range of values for house price deflation which may trigger a recession the following period.     

Climate Change Mitigation with Technology Spillovers

We explore the implications of an increase in clean technology spillovers between developed and developing countries. We build a game of abatements in which players are linked with technology spillovers determined by an initial choice of absorptive capacities by developing countries. We show that, within a non-cooperative framework, the response of clean technology investments in developed countries to an increase in cross-country technology spillovers is ambiguous. If the marginal benefits of these additional abatements are not sufficiently high, developed countries have a strategic incentive to decrease investments. Such a strategic response jeopardizes the initial effects of an increase in technology spillovers on climate change mitigation and decreases the incentives for developing countries to enhance their absorptive capacities.     

Push‐me pull‐you: comparative advertising in the OTC analgesics industry

We derive equilibrium incentives to use comparative advertising that pushes up own brand perception and pulls down the brand image of targeted rivals. Data on content and spending for all TV advertisements in Over‐The‐ Counter (OTC) analgesics enable us to construct matrices of rival targeting expenditures and estimate the structural model. Using brands' optimal choices, these attack matrices identify diversion ratios, from which we derive comparative advertising damage measures. We find that comparative advertising causes more damage to the targeted rival than benefit to the advertiser. We simulate banning comparative advertising to find industry profits rise.     

Liability insurance under the negligence rule

We incorporate the concept of evidentiary standard to the analysis of the negligence rule under liability insurance and court errors. When the postaccident evidence is privately contractible and not too noisy, efficiency is achieved by both strict liability and a negligence rule with appropriate due care and evidentiary standards. When the evidence is not directly contractible, trial outcomes represent useful contractible information for the risk‐incentives tradeoff in the liability insurance policy. Strict liability is then inefficient and dominated by the negligence rule. The negligence rule can itself be improved upon by decoupling damages from the harm suffered by the victim.
