This paper examines social learning when only one of the two types of decisions is observable. Because agents arrive …, as in the standard model, learning is complete if and only if signals are unbounded. If signals are bounded, cascades may …

We exhibit a natural environment, social learning among heterogeneous agents, where even slight misperceptions can have … a large negative impact on long-run learning outcomes. We consider a population of agents who obtain information about … information aggregation can be improved by simplifying agents’ learning environment. The key feature behind our findings is that …

We study to what extent information aggregation in social learning environments is robust to slight misperceptions of … the agents' learning environment …
