Instinctive response in the ultimatum game Brañas Garza, Pablo Meloso, Debrah Miller, Luis Economic experiments Ultimatum game Yes-or-no game Median response time A revised version: Brañas-Garza, P.; Meloso, D.; Miller, L. Interactive and moral reasoning: a comparative study of response time. Innocenzo Gasparini Institute for Economic Research (IGIER), 2013. (Working Paper; 440) 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. 2014-05-02T11:36:58Z 2014-05-02T11:36:58Z 2008 info:eu-repo/semantics/report Brañas-Garza, P.; Meloso, D.; Miller, L.
