The public demand for ecosystem services measured by willingness to pay (WTP) in contingent valuation studies provides important information for designing Payment-for-Ecosystem-Service (PES) programs. However, the hypothetical markets for contingent valuation and respondents’ unfamiliarity...

The numerical certainty scale (NCS) and polychotomous choice (PC) methods are two widely used techniques for measuring preference uncertainty in contingent valuation (CV) studies. The NCS follows a numerical scale and the PC is based on a verbal scale. This report presents results of two...

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...

This study employs stated preference data from a choice experiment to address two issues related to consumer demand for functional dairy products: (1) Consumers’ preferences for functional dairy product attributes in Germany, and (2) are willingness-to-pay estimates obtained in the choice...

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...

We compare the ability of three preference elicitation methods (hypothetical choices, non-hypothetical choices, and non-hypothetical rankings) and three discrete-choice econometric models (the multinomial logit, the independent availability logit, and the random parameter logit) to predict...

This paper estimates the costs of buying water use rights from farmers located in the Mafraq-Azraq basin in Jordan. Farmers’ water supply curve is estimated using data gathered from a contingent valuation survey. Estimation results indicate that a total supply of 29 million m3 could be...

Observed and unobserved characteristics of an individual are often used by researchers to explain choices over the provision of environmental goods. One means for identifying what is typically an unobserved characteristic, such as an attitude, is through some data reduction technique, such as...

Systematic supervision procedures have been proposed to improve contingent valuation surveying, particularly in developing countries. Surprisingly, the CV literature does not say much about the potential effects of supervision even though there is evidence of interviewer effects and social...

This paper presents the method and findings of a contingent valuation (CV) study that aimed to elicit United Kingdom citizens' willingness to pay to support legislation to phase out the use of battery cages for egg production in the European Union (EU). The method takes account of various biases...
