| We evaluate the impact of different information sequences on participants’ hypothetical willingness to pay (WTP) for food produced using nanotechnology. In three treatment groups, information on the health, societal, or environmental impact linked to nanotechnology was revealed in different sequences: an imposed order, a chosen order, and a chosen order after a discussion among participants. Results show that information choice is important. While in the imposed order, the first information revealed has no effect on WTP, the information chosen first has a strong impact. Discussion has no further impact. Health information was a priority and significantly decreased WTP, while societal and environmental information did not significantly influence WTP. |

| Many deficiencies in the capacity of a food system to deliver safe products are systemic in nature. We suggest a taxonomy of four general ways in which a systemic failure might occur. One relates to the connectedness, or topology, of the system. Another arises from mistrust on the part of downstream parties concerning signals on product attributes, production processes, and the performance of regulatory mechanisms. A third arises when asymmetric information leads to low incentives for preserving food quality. Finally, inflexibilities in adapting to different states of nature may leave the system vulnerable to failures. Innovations in information technology and institutional design may ameliorate many problems, while appropriate trade, industrial... |

| Product labeling has gained considerable attention recently, as a means to both provide product-specific information and reduce quality uncertainty faced by consumers, as well as from a regulatory point of view. This article focuses on whether and to what extent origin, quality and traceability labeling is an appropriate way to differentiate food products. The focus is on fresh meat and fresh fish, two mainly generic food product categories with a high degree of credence character. Insights into the potential for market differentiation through origin, quality and traceability labeling are provided and discussed using primary data collected during the period 2000-2005 by means of four consumer surveys. In general, direct indications of quality, including... |

| This paper presents estimates of consumers' willingness to pay for a GM food and non-food product based on data collected in a choice experiment. The choice experiment was part of a survey of 1510 randomly selected consumers in Germany that was mailed in spring 2005. Attitudes towards gene technology, institutions and technical progress were measured using 22 items. A factor analysis revealed five factors describing consumer attitudes: support, risk, trust, attitude towards technical progress and attitude towards technical innovation. Based on these factors we identify four different classes of consumers in a latent class model for both products. Analysis of these classes shows strong differences between willingness to pay estimates for benefits compared... |

| Economic assessments of pesticide regulations typically focus on producer impacts and generally ignore possible changes in product demand. These changes may be nonnegligible if real and/or perceived product attributes change. We measure consumers' willingness to pay (WTP) for the elimination of one insecticide and also a whole group of insecticides in apple production using a multiple-round Vickrey auction. The data are analyzed using nonparametric statistical tests and a double-hurdle model. Our findings show that consumer perceptions of product attributes change if pesticides are removed from production, and this is reflected in WTP changes. WTP is shown to be income elastic. |

| Milk production is seasonal in many European countries. While quantity seasonality poses capacity management problems for dairy processors, a European Union policy goal is to reduce price seasonality. After developing a model of endogenous seasonality, we study the effects of three E.U. policies on production decisions. These are private storage subsidies, production removals, and production quotas. When cost functions are seasonal in a specified way, then arbitrage opportunities interact with storage subsidies to reduce both price and consumption seasonality. But production seasonality likely increases because storage subsidies promote temporal market integration. Conditions are identified under which product market interventions increase quantity... |

| A wide array of food safety scares and breakdowns have led to loss of consumer confidence in the quality and safety of beef products. To counteract such concerns, firms and regulators have the ability to utilize brands or labels to signal quality. Utilizing a mail survey in France, Germany, and the United Kingdom, we analyzed consumer preferences for alternative beef labeling strategies. Using an ordered probit model and a double bounded logit model, we estimate consumer preferences for alternative beef labeling programs. In general, results suggest that consumers have more confidence in government mandated labels as opposed to private brands. French and German consumers place a higher level of importance on brands and labels than do UK consumers.... |

| This paper presents an analysis of food risk perceptions of German consumers over the eleven year period from 1992 to 2002. Using factor analysis, we analyse the respondents general risk attitudes and the specific perception of food safety risks. General risk attitude are described by variables relating to environmental, lifestyle and food risks. Food safety concerns are grouped into concern about use of biotechnology, about residues, about unhealthy eating habits, and about natural contaminants. An ordered probit analysis identifies the characteristics that explain the importance consumers attribute to these different food safety risks. The results reveal that general risk perceptions and knowledge about food safety hazards are highly significant in the... |

| Due to growth and changing distribution channels for organic food in Germany, there is some concern that organic food will lose against local food in the competition for conscious consumers. In this paper we will present the results of a survey in Bavaria searching for consumer motives and label recognition. A choice experiment using different prices, brands and labels is conducted for bread, beer and milk. Results show the importance of local production to the surveyed consumers, similarly for conventional as for organic products. |
