Bid Design and its Influence on the Stated Willingness to Pay in a Contingent Valuation Study AgEcon
Carmona-Torres, Carmen; Calatrava-Requena, Javier.
The CV method estimate the monetary value that specific changes in the provision of goods and services represent for society, which is asked for their Willingness To Pay (WTP) for it, according to their budget and individual preferences, in a survey. The applications of CV are a source of information to important public decision-making. Therefore, it seems to be a desirable objective for a CV study to strive to detect and reduce, as far as possible, the bias affecting the elicited values. In the present work, the starting point bias in an application to the case study of the conservation of the Iberian Lynx in Spain is analyzed. This bias is caused by the potential influence of the bid values offered to the interviewees on their stated preferences. Three...

Designing choice experiments to Test for Anchoring and Framing Effects AgEcon
Kragt, Marit Ellen; Bennett, Jeffrey W..
Choice experiments (CE) are increasingly used as a stated preference technique to value changes in non-market goods. Respondents to a CE survey are asked to make repeated choices between alternatives. Each alternative is described by a number of attributes – the attributes levels vary across alternatives and choice sets. A monetary attribute is typically included so that marginal values for changes in the non-market attributes presented can be estimated. The monetary attribute has central importance. However, there has been limited research on the impacts on respondents’ choices of changing the (range in) levels of the monetary attribute presented in CE surveys. This is known as the ‘anchoring’ effect. The ‘framing’ of non-market attributes may also...

Using a Modified Payment Card Survey on Chinese Consumers’ Willingness to Pay for Fair Trade Coffee: Would the Starting Point Matter AgEcon
Yang, Shang-Ho; Hu, Wuyang.
Coffee consumption in China is increasing rapidly over the recent years. This study offers one of the few initial attempts to not only understand general consumption behavior associated with Chinese coffee, but to explore the viability of niche markets for coffee with the credence attribute “fair trade”. A modified payment card approach was adopted as the consumer willingness to pay elicitation method. Survey results of 564 consumers from the city of Wuhan, China suggest a positive attitude toward coffee as an alternative drink and a willingness to pay a premium for “fair trade” coffee. This study also explores and describes the potential impact of starting point bias, which has been relatively well documented in the dichotomous choice literature but has...
