非整数出价在离散选择实验中触发系统2的完整信息处理
Use of Nonrounded Bids Triggers System 2 Full Information Processing in Discrete: Choice Experiments
摘要
An aspect of bid vector design in choice experiments that has received limited attention is the effect of using non-rounded (or precise) rather than rounded bids. Insights from the marketing and psychology literatures suggests that there are many factors potentially influencing the effects of using non-rounded bids, including image and level effects, accuracy cues, processing fluency, and stimulating more cognitively-based System 2 thinking. Using a split-sample experimental approach in a choice experiment, we find evidence that non-rounded bids may trigger use of System 2 cognitive processes, thereby increasing the number of significant attribute coefficients as well as reducing model variance.
中文摘要
选择实验投标向量设计中一个尚未得到充分关注的方面，是使用非整数（或精确）投标而非整数投标所产生的影响。来自营销学和心理学文献的洞见表明，有许多因素可能影响使用非整数投标的效果，包括形象效应和水平效应、准确性线索、加工流畅性，以及激发更多基于认知的系统2思维。在一项选择实验中采用分样本实验方法，我们发现证据表明，非整数投标可能触发系统2认知过程的使用，从而增加显著属性系数的数量并降低模型方差。
