The effect of information on consumers' willingness to pay for natural and organic chicken

This study examined the effect of definitions for organic and natural on willingness to pay a premium for organic over natural chicken. Data were collected using surveys and experimental auctions that were conducted before and after information was presented. Before information, approximately two‐thirds of participants inaccurately equated the requirements of natural with those for organic. After information, nearly 50% increased their premium, while 30% decreased their premium. Logistic regression results showed that consumers who had overestimated the requirements for natural were most likely to have an increased premium after information, with significantly higher bids for organic. For those who decreased their premium after information, awareness of consuming genetically modified (GM) foods was a key variable. The non‐genetically modified (non‐GM) requirement of organic appears to be of low value to some consumers. Overall, consumer confusion regarding organic and natural standards may be having substantial impacts on the two markets.     

COOPERATION: THE POWER OF A SINGLE WORD? SOME EXPERIMENTAL EVIDENCE ON WORDING AND GENDER EFFECTS IN A GAME OF CHICKEN

Framing has been widely shown to affect decision making. In this paper, we investigate experimentally whether, and to what extent, cooperative behaviour in a Game of Chicken may be impacted by a very basic change in the labelling of the strategies. Our within‐subject experimental design involves two treatments. The only difference between them is that we introduce either a socially‐oriented wording (I cooperate/I do not cooperate) or colours (red/blue) to designate strategies. The level of cooperation appears to be higher in the socially‐oriented context, but only when uncertainty as regards the type of the partner is manipulated, and especially among females.

Food Scares and Trust: A European Study

The complex interactions between the determinants of food purchase under risk are explored using the SPARTA model, based on the theory of planned behaviour, and estimated through a combination of multivariate statistical techniques. The application investigates chicken consumption choices in two scenarios: (a) a ‘standard’ purchasing situation; and (b) following a hypothetical Salmonella scare. The data are from a nationally representative survey of 2,725 respondents from five European countries: France, Germany, Italy, the Netherlands and the United Kingdom. Results show that the effects and interactions of behavioural determinants vary significantly within Europe. Only in the case of a food scare do risk perceptions and trust come into play. The policy priority should be on building and maintaining trust in food and health authorities and research institutions, while food chain actors could mitigate the consequences of a food scare through public trust. No relationship is found between socio‐demographic variables and consumer trust in food safety information.     

The evolution of conventions under incomplete information

Summary. We formulate an evolutionary learning process with trembles for static games of incomplete information. For many games, if the amount of trembling is small, play will be in accordance with the games (strict) Bayesian equilibria most of the time. This supports the notion of Bayesian equilibrium. Often the process will select a specific equilibrium. We study an extension to incomplete information of the prototype conflict known as Chicken and find that the equilibrium selection by evolutionary learning may well be in favor of inefficient Bayesian equilibria where some types of players fail to coordinate.Received: 17 March 2003, Revised: 3 December 2003, JEL Classification Numbers: C72.     

我国对美国白羽肉鸡产品反补贴案上游补贴规则的运用与述评

通过对美国肉鸡产品反补贴案法律规则适用情况的分析,发现这是我国商务部借鉴美国上游补贴规则的理论和实践,首次运用上游补贴规则进行补贴利益传递分析并做出肯定性裁决的案件。尽管在我国法律法规没有明文规定上游补贴规则的情况下,我国商务部的这种做法可能存在重大的法律瑕疵,但也表明了我国亟需制定上游补贴规则的紧迫现实。为此,现阶段我国的上游补贴立法和实践应注意投入产品所接受补贴的性质、上游补贴的保护对象、上游补贴的地域性限制及审慎适用等问题。

Are Consumers Willing to Pay for Local Chicken Breasts and Pork Chops?

Consumer definitions of and demand for locally produced meat were collected via an online survey of 625 U.S. residents. Consumer choice experiments were utilised to elicit willingness to pay for locally produced chicken breasts and pork chops. Younger respondents, respondents without a college degree, participants in hunting and fishing and those who have altered their total meat consumption in the past 3 years due to food safety or animal welfare concerns more frequently report that local food is produced within 10 or 20 miles of their home. Results indicate that respondents are willing to pay a positive amount (at the mean) for verified local production of chicken breasts but not pork chops.
