Research Seminar by Tatiana Kornienko (University of Edinburgh)

On Thursday, March 31 at 4.40 pm, room 3211 (Shabolovka str. 26) ICEF held the Research Seminar.
Speaker: Tatiana Kornienko (University of Edinburgh)
Theme: "Lone Wolf or Herd Animal? An Experiment on Choice of Information and Social Learning" joint with John Duffy and Ed Hopkins

Abstract: We report on an experiment that uses revealed preference to distinguish between rational social learning and behavioral bias. Subjects must choose between receiving a private signal or observing the past guesses of other subjects before guessing the state of the world. The design varies the persistence of the state across time. This changes whether choosing social or private information is optimal. We can therefore separate subjects who choose optimally from both those who excessively use social information (“herd animals”) and those with excessive use of private information (“lone wolves”). While aggregate behavior appears unbiased, this is because the numbers of lone wolves and herd animals are approximately equal.
