Abstract:
In a series of recent papers, Ariel Rubinstein claims that the study of response time sheds light on the process of reasoning involved in classical economic decision problems. In particular, he considers that a distinction can be drawn between instinc- tive and cognitive reasoning. This paper complements and expands upon Rubinstein's study on time responses. We show that strategic risk is the key element in explaining differences in median response time in ultimatum behavior.
