| For quite a while, stated preferences have been a major tool to measure consumer preferences for new products and services. Revealed preference methods, in particular experimental economics, have gained popularity recently because they have been shown to be more incentive compatible, and therefore more accurate. However, this advantage comes at the expense of higher survey costs. In the developing countries with limited funding for research, it is important to determine whether the extra cost can be justified by the extra gain in accuracy. A survey of 100 farmers was carried out in Western Kenya to determine consumer preference for yellow maize using the contingent valuation, choice experiments and experimental auction methods. Experimental auctions... |

| This paper examines Finnish citizens' attitudes towards multifunctional agriculture and further, the connections among these attitudes, consumers' willingness to pay, and some socio economic factors. Attitudinal dimensions were executed by using factor analysis. The respondents (N=1300) were distributed into clusters based on their attitudes. It would be expected that people who have positive attitudes, would also state high values of WTP. Instead, this study suggests that attitudes and open-ended WTP do not have a positive relation. People are willing to support domestic agriculture as a provider of safe and high-quality food. However, a remarkable proportion of Finnish citizens have a positive attitude towards externalities and joint products of... |

| The dispute between the US and EU over GM foods at the WTO is examined in terms of the issues it raises about protectionism and environmental protection and precaution. The issue of whether GM, GM Derived and Non-GM foods are equivalent to each other is examined using data from a national choice modelling study in the UK. These categories of food are critical since they underpin the EU's new food labelling regime which it hoped would defuse the WTO dispute. The results are analysed using a Bayesian mixed logit model which allows greater flexibility in the modelling of preference distributions. This is particularly crucial where, as in this case, bi-modal distributions are identified with some indifferent or mildly averse to GM foodtypes while others are... |

| This paper uses a payment card approach to reveal consumers‟ willingness to pay for green food in China. We first present a brief introduction of the payment card approach and introduce several methods to estimate the WTP with payment cards, which we subsequently use to estimate WTP values regarding green vegetables, green meat and green eggs in China. Our results indicate that consumers in big cities are willing to pay a higher premium for green food and that WTP values are relatively higher for more expensive food than for cheaper food. In addition, the ratios of premium to price range mainly between 25% and 50% and WTP values obtained from interval midpoint approach are relatively higher than those calculated by other approaches. |

| Estimates of the compensating surplus generated by changes in non-marketed environmental amenities can be estimated using stated preference valuation techniques. These are typically framed in terms of WTP tradeoffs, even if the situation of interest involves a property right vestment that calls for a WTA question. The differences created by the two questioning formats are explored in this paper using the results of two choice modelling applications. Both applications were framed on the potential for irrigation development and environmental losses in the Fitzroy River Basin, Central Queensland. The scenarios used in the applications differed only in that they used alternatively WTP and WTA questioning formats. The results indicate that robust models could... |

| Much of Hawaii’s economy relies on its unique marine environments, which are threatened by degradation from stormwater runoff. Using a stated preference method of choice-based conjoint (CBC) analysis, based on stylized photographs, this study examines both residents’ and visitors’ marginal value for levels of attributes associated with Hawaiian beach recreation. Each attribute (sand quality, water quality, congestion and water safety conditions) was significant for both residents and tourists, with water quality being the single most important attribute. There is little distinction between resident and tourist marginal value, except for a greater value lost for below average water quality among tourists. |
