摘要翻译:
惯性和依赖于上下文的选择效应是行为现象中研究得很好的一类。虽然孤立地对这些影响知之甚少,但当两者都可能存在时,它们中的一个是否“支配”另一个却知之甚少。任何这种优势的知识对于有效的选择、架构和描述性建模都是相关的。我们以一个被试间的实验室实验开始了这一实证调查,该实验以一个对两三张彩票的单一决定为特征。我们的实验旨在测试现状偏差和诱饵效应之间的优势。我们发现了现状偏见的有力证据,但没有诱饵效应的证据。我们还发现,现状偏见足够强大,以至于在总体水平上,一小部分受试者从厌恶风险转向寻求风险。调查证据表明,这是由于当风险彩票是默认的时,受试者关注最大可能金额,当没有默认彩票时,受试者关注比最小金额更多的中奖概率。观察到的风险态度的逆转可以用一大类参照依赖的偏好来解释。

英文摘要:
  Inertia and context-dependent choice effects are well-studied classes of behavioural phenomena. While much is known about these effects in isolation, little is known about whether one of them "dominates" the other when both can potentially be present. Knowledge of any such dominance is relevant for effective choice architecture and descriptive modelling. We initiate this empirical investigation with a between-subjects lab experiment that featured a single decision over two or three money lotteries. Our experiment was designed to test for dominance between *status quo bias* and the *decoy effect*. We find strong evidence for status quo bias and no evidence for the decoy effect. We also find that status quo bias is powerful enough so that, at the aggregate level, a fraction of subjects switch from being risk-averse to being risk-seeking. Survey evidence suggests that this is due to subjects focusing on the maximum possible amount when the risky lottery is the default and on the probability of winning more than the smallest amount when there is no default lottery. The observed reversal in risk attitudes is explainable by a large class of reference-dependent preferences.
