Fairness in markets and market experiments: insights from a field‐plus‐lab study and a failed replication
研究实验室市场实验中的公平行为与公平贸易产品偏好之间的关系，原始样本中发现两者相关，但十年后的复制实验未得到显著结果，表明关系可能很弱。
Abstract We investigate how fairness in a laboratory experiment framed as a market exchange relates to preferences for fair trade products elicited before and at the end of the experiment. We collected two samples, 10 years apart. In the original sample, fairness in the market experiment measured by the willingness to buy at a higher price when higher wages are paid to the worker correlates both with the choice of a fair trade product and with the willingness to pay a positive fair trade premium. These correlations are not significant in the replication experiment, which indicates at best a weak relationship.
