The Effect of Risk Characteristics on the Willingness to Pay for Mortality Risk Reductions from Electric Power Generation

The objective of this study is to estimate willingness to pay (WTP) for the reduction of mortality risks caused by fossil fuel (natural gas, coal and oil) versus nuclear electric power generation systems and to examine the influence of risk characteristics involved with electric power generation on WTP. A choice experiment was conducted to achieve these objectives. The attributes for nuclear risks in the experiment included the probability of disasters and the expected losses if a disaster occurs. We find evidence of (i) a baseline effect (where WTP is sensitive to hypothetical versus actual baseline expected mortality); (ii) a ‘labeling effect,’ where, surprisingly, the term ‘nuclear’ has no effect on WTP, but the term ‘fossil-fueled power generation’ results in lower WTP; and (iii) disaster aversion, meaning that people focus on the conditional loss from a nuclear disaster, not the probability. We also find that the WTP for reducing deaths from a nuclear disaster is about 60 times the WTP for routine reducing fossil-fuel generation-related deaths.     

Performance Evaluation of Audit Assistants in Chartered Accounting Firms

The development of efficient and competent staff in accounting firms is enhanced by the use of formal performance evaluation systems. This paper reports on a study which examined the objectives and uses of performance evaluation, the methods used, the dimensions evaluated, the development of overall assessments, the provision of feedback and the perceived strengths and weaknesses of the systems in use. In general, the performance evaluation process in these firms is effective, but there is scope for improvement in a number of areas.     

Organic Food at the Point of Purchase: Understanding Inconsistency in Consumer Choice Patterns

The organic food category, while still small in terms of world food production, has continued to grow in many markets in the developed world. This article focuses on understanding the barriers and facilitators to purchasing organic food at the final hurdle: the point of purchase (POP). A qualitative study has identified seven factors that influence buyer behavior at the POP, and these are consumer intention to purchase organic food when entering the retail outlet; habit; availability; false assumptions; visibility and access of organic food; visual and olfactory cues; and price. These can often be the final hurdle to consumers choosing (or not) organic food at the POP.     

Allocation of public funds to R&;D: a portfolio choice-styled decision model and a biotechnology case study

A decision problem—allocating public research and development (R&D) funding—is faced by a planner who has ambiguous knowledge of welfare effects of the various research areas. We model this as a reverse portfolio choice problem faced by a Bayesian decision-maker. Two elements of the planner’s inferential system are developed: a conditional distribution of welfare ‘returns’ on an allocation, given stated preferences of citizens for the different areas, and a minimum risk criterion for re-allocating these funds, given the performance of a status quo level of funding. A case study of Canadian public research funds expended on various applications of agricultural biotechnology is provided. The decision-making methodology can accommodate a variety of collective expenditure and resource allocation problems.     

Consumer's Responses to the Potential Use of Bovine Somatotrophin in Canadian Dairy Production

The responses of a random sample of consumers to the use of recombinant somatotrophin (rBST) in milk production were elicited using a stated preference methodology. A conditional logit model of consumer choice was developed and tested to analyze consumers' choices of milk with varying characteristics of fat content, price, freshness and rBST treatment. Welfare calculations for a representative consumer indicate welfare losses with the introduction of rBST. Welfare losses were slightly less for a male than a female household food purchaser and were less for food purchasers with higher levels of income and education. There was a small welfare gain when the representative food purchaser was offered a full range of “rBST” and “wn-rBST” milks. The resiilts suggest that making appropriately labelled “rBST-free” milk available to consumers could decrease consumer welfare losses associated with the introduction of rBST in Canada. Nous avons évalueé par une méthodologie des préférences déclarées les réponses d'un panel de consommateurs choisis au hasard envers l'utilisation de somatotropine bovine recombinante (rBst) dans la production laitière. Un modèle logit conditionnel des choix du consommateur est testé pour analyser les choix à la consommation à l'égard de laits de divers niveaux de teneur en matière grasse, de prix et de fraîcheur et provenant ou pas de vaches traitées à la rBst. Les coûts sociaux pour le consommateur représentatif font voir des pertes éonomiques avec l'introduction de la rBst. Ces pertes étaient légèrement moins importantes lorsque l'acheteur d'aliments pour le ménage était un homme plutôt qu'une femme ou que son niveau d'éducation et de revenu était plus élevé. On observait un léger avan-tage économique lorsque le pourvoyeur du ménage représentatif avait accès à toute la gamme des laits avec et sans rBst. Il ressort de ces observations qu'une indication Claire de l'absence de rBst dans le lait sur l'étiquette des produits offerts à la consommation pourrait diminuer les pertes économiques résultant pour le consommateur de l'introduction de la rBst au Canada.     

Implications of Realization Uncertainty on Random Utility Models: The Case of Lottery Rationed Hunting

Conditional multinomial logit (MNL) models are often used to estimate the value of nonmarket resources under the assumption that consumer choices will be realized with certainty. The conditional MNL may not be appropriate when choices made may not be realized with certainty, such as when rationing mechanisms are used as a means of managing nonmarket resources. Two models that address this issue, developed by Boxall (1995) and Rouwendal (1989), are compared here to estimate welfare measures for moose hunting in Newfoundland. The results from these two models differ significantly from the results of a simple conditional MNL model .
Les modèles logit multinomiaux conditionnels (MNL) sont souvent utiliés pour calculer la valeur de ressources non marchandes, dans une hypothèse de départ voulant que les choir du consommateur sont assurés d'être réalisés. Ce genre de modèle peut toutefois ne pas convenir lorsque les choix fait ne sont pas assurés d'être pleinement réalisés, comme dans les cas où des mécanismes de rationnement sont imposés comme moyen de gérer ces ressources non marchandes. Nous comparons deux modèles conçus et mis au point, l'un par Boxall (1995), l'autre par Rouwendal (1989), pour estimer les mesures des effets socio-économiques d'une réglementation de la chasse de l'orignal a Terre-Neuve. Il apparaêt que ces deux modèles aboutissent à des résultats significativement différents de ceux obtenus par un modèle MNL conditionnet simple .     

Influence of strategies and heuristics on farmers' response to change under uncertainty

Hierarchical Decision Models of woolproducers' decisions provide unique insights into the impact of major price changes. Producers' lagged response in some contexts appear to be due to the ambiguous decision environment they face, their strategic goals and responses to that environment apart from lags caused by factors such as attitude to risk, expectations adjustment, adjustment costs and learning costs. Much of the response to major price changes comes from strategic decisions to change enterprises rather than marginal changes to existing enterprises. In ambiguous environments, methods may need to be found that incorporate simplifying behavioural rules and strategies.     

One little Lebanese cucumber is not going to break the bank: Price in the choice of fresh fruits and vegetables

This paper reports on empirical research into individual consumer behaviour in the context of fresh fruit and vegetable purchases. The discussion draws on research results from two studies conducted around the actual shopping process. The findings suggest that consumers' price response behaviour may not be consistent with that predicted by economic theory and that this could be significant at the aggregate level. The existence of 'acceptable price ranges' points to the presence of price thresholds within which consumers are relatively insensitive to price movements. Also of relevance is that the primary influence of the budget constraint may be at a broader level rather than at the level of choosing particular products.
