Abstract: We test whether anchoring affects people's elicited valuations for a bottle of wine in individual decision making and in markets. We anchor subjects by asking them if they are willing to sell a bottle of wine for a transparently uninformative random price. We elicit subjects' Willingness-To-Accept for the bottle before and after the market. Subjects participate in a double auction market either in a small or a large trading group. The variance in subjects' Willingness-To-Accept shrinks within trading groups. Our evidence supports the idea that markets have the potential to diminish anchoring effects. However, the market is not needed: our anchoring manipulation failed in a large sample. In a concise meta-analysis, we identify the circumstances under which anchoring effects of preferences can be expected.The file contains the raw experimental data as exported by the experimental software.<br><br>

摘要：我们在个体决策与市场情境下，检验锚定效应（anchoring）是否会影响个体对一瓶葡萄酒的诱导估值。我们通过询问被试是否愿意以一个明显无信息价值的随机价格出售该瓶葡萄酒，对其施加锚定。我们分别在市场实验前后，收集被试对该葡萄酒的接受意愿（Willingness-To-Accept）。被试将以小型或大型交易群体的身份参与双向拍卖市场实验。交易群体内部，被试的接受意愿方差会出现缩减。本研究的实验证据支持"市场具备削弱锚定效应的潜力"这一观点。但市场并非必要条件：我们的锚定操纵在大样本实验中未产生显著效果。在一项简洁的元分析中，我们明确了可观测到偏好锚定效应的实验情境。本文件包含由实验软件导出的原始实验数据。
