AbstractWe use a revealed preference approach to disentangle conformity, an intrinsic taste to follow others, from information-driven herding. We provide ob- servations from a series of sequential decision-making experiments in which sub- jects choose the type of information they observe before making their decision. Namely, subjects choose between observing a private (statistically informative) signal or the history of play of predecessors who have not chosen a private signal (i.e., a statistically uninformative word-of-mouth signal). In our setup, subjects choose the statistically uninformative social signal 34% of the time and, of those, 88% follow their observed predecessors' actions. When allowing for payoff from the majority treatment demonstrate that conformist behavior is not driven by inequality aversion, nor by strategic voting behavior in which voters balance others who are uninformed. Raising the stakes five-fold does not eliminate conformist behavior; in both treatments, the social signal is chosen nearly 50% of the time. Individual level analysis yields the identification of rules of thumb subjects use in making their decisions.
