We consider an information design problem when the sender faces ambiguity regarding the probability distribution over … admits a representation as a randomization over mechanisms consisting of two messages. A small level of uncertainty regarding … the receiver's prior makes the sender more truthful than in the full information benchmark, but as uncertainty increases …

over a set of probability distributions. This paper demonstrates that the contract that maximizes the minimum payoff over … all possible probability distributions of quality is a screening menu that separates all types, whereas the optimal … contract for any given probability distribution is a posted price, which induces bunching. Using the e-contamination model …

In traditional sequential search models, players face ex ante uncertainty prior to each search but obtain certain … modified sequential search model with ex post uncertainty in which the uncertainty cannot be fully eliminated by the search. In … our theory in a laboratory experiment with a search game to track subjects' behavior and use a multiple price list and a …
