This paper presents evidence on the stability and behavioural validity of alternative survey mechanisms for eliciting farmers' attitudes towards risk. Three hypothetical instruments are considered that differ in terms of the simplicity, context, and payoff scale of the decision presented to respondents. Responses are assessed in terms of their relative ability to explain actual farmer crop insurance purchases. Results indicate that measures of risk attitudes are poorly correlated across alternative mechanisms. The strongest positive evidence of behavioural validity is found for the gamble task explicitly defined in the context and scale of farmers' economic activities pertaining to their insurance purchase decision.
In many environmental valuation applications standard sample sizes for choice modelling surveys are impractical to achieve. One can improve data quality using more in‐depth surveys administered to fewer respondents. We report on a study using high quality rank‐ordered data elicited with the best‐worst approach. The resulting “exploded logit” choice model, estimated on 64 responses per person, was used to study the willingness to pay for external benefits by visitors for policies which maintain the cultural heritage of alpine grazing commons. We find evidence supporting this approach and reasonable estimates of mean WTP, which appear theoretically valid and policy informative.
