Choice Certainty and Consistency in Repeated Choice Experiments
研究了陈述偏好实验中重复选择如何影响偏好学习，通过自报确定性分析发现学习存在但未显著影响参数估计，且偏好稳定一致。
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.
