Functional foods: a conceptual definition

Purpose – To draw the frontiers of the functional food universe, to identify concepts that should be included in a broadly accepted functional food definition and to propose a definition.Design/methodology/approach – Based on a review of the literature and the Delphi technique with a group of North American and European experts.Findings – Four concepts were identified: the nature of food, health benefits, functions and regular consumption. Two dimensions, physiological effects and functional intensity, were developed to define the frontiers of the functional food universe and a definition is suggested.Practical implications – A large number of definitions as well as great variations within definitions make it difficult to provide industry partners with robust information on market trends and market potential, or to appropriately protect consumers through legislation. This paper should contribute to the debate surrounding the type of food that should be considered a functional food and surrounding the lack...

Simultaneous Allocation of Bundled Goods through Auctions: Assessing the Case for Joint Bidding

We use the experimental method to study the costs and benefits of allowing joint bidding in simultaneous multi-unit first price sealed bid auctions for bundled goods. The research has immediate applications to the sale of public forest stands that arbor a mixture of species. Joint bidding and communication raise the prospect of higher allocative efficiency, but also of collusive bidding through a reduction in the number of bidders and a greater scope for the formation of bidding rings. However, we find that allowing joint bidding has a significant positive impact on efficiency and reduces collusion significantly. We also explore the robustness of the results to characteristics of the auction environment that are relevant to timber auctions.

Keep It Down: An Experimental Test of the Truncated k-Double Auction

The introduction of a centralized institution for trading production rights in quota-regulated agricultural sectors can dramatically improve the flow of information among market participants and increase efficiency. On the other hand, prevailing conditions in these small markets can provide sellers with a market advantage, yielding high quota prices that impose important financial costs on quota holders and limit the entry of new producers into the industry. In this paper, we modify the normal allocation rule of the k-double auction (kDA) to counter thin market conditions and to favor buyers who bid low prices. In laboratory experiments, we test the “truncated” kDA (T-kDA) against a regular kDA for its ability to affect buyer and seller behavior and decrease equilibrium prices, and assess how it impacts efficiency. The results show that the T-kDA significantly lowers the equilibrium price and results in moderate efficiency losses. Most importantly, the T-kDA effectively counters the market power of oligopolists when demand far outstrips supply.

Integrating agroforestry intercropping systems in contrasted agricultural landscapes: a SWOT-AHP analysis of stakeholders’ perceptions

Agroforestry intercropping systems have been developed as an alternative to conventional monocropping systems to address environmental, social and economic issues in a wide array of agricultural contexts. As research on the biological properties of these systems tends to demonstrate their potential, fostering their integration in agricultural landscapes requires an in-depth understanding of local stakeholders’ perceptions. Our study used the strengths, weaknesses, opportunities and threats approach in combination with the analytical hierarchy process (SWOT-AHP) to investigate the factors influencing local stakeholders’ decision to integrate agroforestry intercropping systems in two Regional County Municipalities and their perception of the relative suitability of three agroforestry intercropping system designs (crop-oriented, tree-oriented and landscape aesthetic-oriented). We conducted focus groups with farmers, farm and forestry advisors, urban planners and local authorities in a very intensive and a very extensive agricultural landscape in Quebec (Canada) and compared the results between stakeholders within and across the areas. Our results show that social factors seem to have more impact than biophysical factors on the decision to integrate agroforestry intercropping systems in intensive and extensive agricultural landscapes. The relative value given to the decision factors varies greatly across stakeholders’ categories and areas. Agroforestry intercropping systems designed to meet crop production needs or landscape aesthetic purposes are perceived as more suitable in both agricultural contexts than the tree-oriented design. Our results highlight crucial issues for agroforestry intercropping system deployment and the development of relevant agroforestry system designs through collective decision-making processes.

Investment Behavior of Canadian Egg Producers: Analyzing the Impacts of Risk Aversion and Variability of Prices and Costs of Production

Animal welfare is a major concern for consumers. This concern has not gone unnoticed by sector stakeholders, especially egg producers. One of the fundamental changes likely to affect egg producers regards modes of production, specifically changes in housing systems, ranging from conventional cages to free range. From farmers’ perspective, changing their mode of production generates a technological and economic/marketing risk. This study documents the level of risk in the Canadian egg sector (conventional and specialty eggs) using data from 2009 to 2011. Our results indicate multiple uncertainty sources (technological, cost of production, price of eggs) that vary according to the types of eggs. We use a quadratic programming approach applied to expected mean-variance models to analyze the impact of risk on decision to invest when the resources must be allocated to different types of production that have different risk levels. Overall our results show how, given risk aversion parameters, producers minimize their risk levels by devoting their resources to the least risky type of eggs. An important result of our study is that supply management, by reducing the perceived risk level, has favored the development of specialty eggs, for the benefit of consumers.
