This paper studies an information design problem in a sequential consumer search environment. Consumers, whose valuation of firm's products is uncertain, observe a noisy signal about the valuation upon being matched with a firm. The goal is to characterize those signal structures that maximize...

This paper studies robust Bayesian persuasion of a privately informed receiver in which the sender only has limited knowledge about the receiver's private information. The sender is ambiguity averse and has a maxmin expected utility function. We show that when the sender faces full ambiguity,...

This paper studies the welfare effects of information in a sequential consumer search environment. Consumers search in the market and observe a noisy signal about the match value upon being matched with a firm, based on which they make their purchasing decisions. We construct the class of...

This paper studies the reputation effect in which a long-lived player faces a sequence of uninformed short-lived players and the uninformed players receive informative but noisy exogenous signals about the type of the long-lived player. We provide an explicit lower bound on all Nash equilibrium...

This paper uses a mechanism design without transfer approach to investigate the optimal communication mechanism in a two-division organization. The principal, with perfect commitment power on multiple decision rules, wants decisions to be both adapted to local conditions and coordinated with...

The third and final study examines the causal relationship between uncertainty about macroeconomic fundamentals and return volatility. The underlying question is: does higher return volatility result in higher uncertainty in beliefs amongst analysts, or the other way around? Using daily data on...
