New Economic Experiments by Using Eye-Tracking Machine

点击翻译按钮获取中文摘要

The aim of this research is to find new insights and enrich the results of previously -conducted economic experiments by using an eye-tracking machine. The eye-tracking machine can analyze subjects' information-processing behavior by checking their eye-movements. The experiments we have conducted so far are related to social preferences and strategic sophistication. The results of these experiments show that the classification by eye-tracking machine is consistent with that by other "usual" methods, e.g. the analysis of observed-choice data. Although the statistical analysis of eye-tracking data is complex, we have succeeded in finding a way to make use of it.
