A comparison of hypothetical risk attitude elicitation instruments for explaining farmer crop insurance purchases
比较三种调查方法（简单性、情境和报酬规模不同）诱导农民风险态度的稳定性与行为有效性，发现不同方法结果相关性差，只有明确以保险购买决策为背景的赌博任务能有效解释实际购买行为。
This article 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.
