英文文献：On the Validity of Gamble Tasks to Assess Farmers' Risk Attitudes-试论赌博任务评估农民风险态度的有效性
英文文献作者：Menapace, Luisa,Colson, Gregory
英文文献摘要：
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.
本文提供了关于激发农民对风险态度的替代性调查机制的稳定性和行为有效性的证据。三种假设工具被认为是不同的简单性，背景和回报规模的决定，向受访者提出。根据他们解释实际农民购买作物保险的相对能力来评估反应。结果表明，风险态度的衡量是不相关的替代机制。在与农民购买保险决策相关的经济活动的背景和规模中明确定义的赌博任务，行为效度的最有力正向证据被发现。
