人们发现，利他偏好对于解释大量陈述偏好调查中确定的实质性非使用价值非常重要。然而，分析利他主义对支付意愿（WTP）影响的研究低估了通过既定措施衡量利他主义的挑战。我们利用自然发生的决策域来调查利他主义在规定偏好研究中的作用。我们采用从互联网调查小组收集的新颖数据集，其中包含受访者过去向慈善机构捐赠的调查硬币，并使用这些数据来分析捐赠行为对同一受访者的支付意愿的影响。我们分析了两项有关环境主题的条件评估调查的捐赠行为。捐赠者在匿名且无关的环境中被证明是给予者，就像独裁者游戏中的决策一样。我们发现，即使在控制了利他主义、生态和环境态度的规定措施之后，受访者过去的捐赠也与较高的支付意愿相关。结果表明，规定的利他主义的衡量标准未能捕捉到利他主义的重要方面，这意味着之前基于此类衡量标准的利他主义研究可能会受到质疑。研究结果还支持研究表明，一个决策领域中的利他行为可以很好地预测其他领域中的利他行为。
Altruistic preferences have been found to be important for explaining the substantial non-use values identified in numerous stated preference surveys. However, studies analysing the effect of altruism on willingness to pay (WTP) have underestimated the challenges of measuring altruism by stated measures. We exploit a naturally occurring decision domain to investigate the role of altruism in stated preference studies. We employ a novel dataset, collected from an Internet survey panel, that contains respondents’ past donations of earned survey coins to charities and use these data to analyse the effect of donation behaviour on the same respondents’ WTP. We analyse donation behaviour across two contingent valuation surveys on environmental topics. Donators are proven givers in an anonymous and unrelated setting, much like decision-making in a dictator game. We find that respondents’ past donations are associated with higher WTP, even after controlling forstatedmeasures of altruism, ecological, and environmental attitudes. The results suggest that measures of stated altruism fail to capture important aspects of altruism, implying that previous studies of altruism based on such measures may be questioned. The results also support research demonstrating that altruistic behaviour in one decision domain is a good predictor of altruistic behaviour in other domains.
