(Pro-)Social Learning and Strategic Disclosure
2025-10-28
We study a sequential experimentation model with endogenous feedback. Agents choose between a safe and risky action, the latter generating stochastic rewards. When making this choice, each agent is selfishly motivated (myopic). However, agents can disclose their experiences to a public record, and when doing so are prosocially motivated (forward-looking). Disclosure is both polarized (only extreme signals are disclosed) and positively biased (no feedback is bad news). The extent of disclosure is non-monotone in prior uncertainty. Subsidizing disclosure costs can paradoxically lead to less disclosure, but more experimentation. (JEL D81, D82, D83)
