讲座主题：The Social Value Of Information Uncertainty
摘要：Information acquisition can favor social welfare despite that informed trading distorts risk-sharing anddestroys trading opportunities. We analyze a Grossman-Stiglitz economy with heterogeneous endowment shocks, where acquiring information is costly and uncertain. Investors make optimal probabilistic information choices subject to a monetary cost, which give rise to an anticipatory benefit that can improve overall welfare. Welfare improvement can be substantial when risk-sharing incentives are weak, endowment shocks are small, and information precision is moderate. Moreover, with heterogeneous endowment shocks, there can be a continuum of Pareto optimal information-acquisition equilibria.
