Observational learning is typically examined when agents have precise information about their position in the sequence … individuals and receive a private signal about the state of the world. We show that social learning is robust to position … uncertainty. Under any sampling rule satisfying a stationarity assumption, learning is complete if signal strength is unbounded …

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

We study market dynamics when an owner learns over time about the quality of her asset. Since this information is … private, the owner sells strategically to a less informed buyer following sufficient negative information. In response, market … information, buyers suffer greater adverse selection, and prices fall accordingly. Eventually, the probability of a strategic sale …

Motivated by the proliferation of user-generated product-review information and its widespreaduse, this note studies a … product quality.
