Strategic Pricing, Signalling, and Costly Information Acquisition

Consider a market where an informed monopolist sets the price for a good or as set with a value unknown to potential buyers. Upon observing the price, buyers may pay some cost for information about the value before deciding on purchases. To restrict buyer beliefs we generalize the idea of the Cho--Kreps ``intuitive criterion''. Then there is no separating equilibrium with fully revealing prices. Yet, as the cost of information acquisition becomes small, the equilibrium approaches the full information outcome and prices become perfectly revealing.
