本研究的主要目的是考察重复选择对陈述偏好实验中偏好学习的影响。我们通过分析反应模式来检验与偏好学习相关的不同假设，并在选择实验中要求受访者报告他们在完成选择任务时的经验确定性。在分裂样本检验中，我们证明了后续选择确定性问题是程序不变的。自我报告的确定性结果表明学习发生了，但计量经济学检验程序没有发现学习效应对参数估计或选择任务的方差有任何显著影响。对选择一致性的额外测试表明，选择实验中的偏好是稳定和连贯的。
The main objective of this study is to examine how repeated choice affects preference learning in stated preference experiments. We test different hypotheses related to preference learning by analyzing response patterns and asking respondents in a choice experiment to report their experienced certainty when going through the choice tasks. In a split-sample test, we show that follow-up choice certainty questions are procedural invariant. The self-reported certainty results indicate that learning occurs, but econometric testing procedures do not identify any significant impact of learning effects on parameter estimates or variance across choice tasks. Additional tests of choice consistency suggest that preferences in the choice experiment are stable and coherent.
