We designed four observational learning experiments to identify the key channels that, along with Bayes … observational learning accounts for the phenomenon of excessive herding, it captures well herd behavior with medium quality signals …-rational inferences, drive herd behavior. In Experiment 1, unobserved, whose actions remain private, learn from the public actions made in …

We report two information cascade game experiments that directly test the impact of altruism on observational learning … substantial public information which increases the earnings of participants. In Experiment 2, participants have better … opportunities to learn about the strategies played by observed which amplifies the impact of altruism on observational learning. …

This paper develops a theory in which heterogeneity in political preferences produces a partisan disagreement about … objective facts. A political decision involving both idiosyncratic preferences and scientific knowledge is considered. Voters … voters' intrinsic preferences or because of rigidities in the political process. The theory predicts that providing mixed …

Furthermore, we determine that the correlation … on simplifying decision-making techniques in general or to reject all of them. Alternatively, this finding may suggest …

We study social learning in a social network setting where agents receive independent noisy signals about the truth …

The paper investigates social-learning when the information structure is not commonly known. Individuals repeatedly … interact in social-learning settings with distinct information structures. In each round of interaction, they use their … behavior in the long-run if and only if individuals distinguish social-learning settings and receive rich feedback after each …

In a setting which adds 'conversational' learning about both the payoff outcomes of … though they can discuss the outcomes of their choices. Models of informational herding or cascades have examined how rational …

We analyze a game theoretic model of social learning about a consumption good with endogenous timing and heterogeneous … increase the probability of herding on consumption of both high and low quality goods …
