In many instances of price discrimination, a seller of an item is in possession of signals from competing buyers regarding their private valuation for the item. If the seller uses this information to price discriminate against the buyer, buyers would correspondingly modify their signalling...

We analyze a model of monopolistic price discrimination where only some consumers are originally sufficiently informed about their preferences, e.g., about their future demand for a utility such as electricity or telecommunication. When more consumers become informed, we show that this benefits...

We examine optimal selling mechanisms with ex-ante commitment for a nondurable good when the seller does not observe the times at which strategic consumers arrive on the market and how much they are willing to pay for the good. Assuming consumer risk neutrality, we demonstrate in this...

This paper examines the optimal sequencing of sales in the presence of network externalities. A firm sells a good to a group of consumers whose payoff from buying is increasing in total quantity sold. The firm selects the order to serve consumers so as to maximize expected sales. It can serve...

We study the informational role of prices in a stochastic environment. We provide a closed-form solution of the monopoly problem when the price imperfectly signals quality to the uninformed buyers. We then study the effect of noise on output, market price, information flows, and expected...

In the standard monopolistic screening problem, buyers obtain information rent as a result of possessing private information; if a contract can be offered before the buyer knows his valuation, the seller can extract the full (expected) surplus. I consider a situation where the buyer may or may...

Extending Milgrom and Roberts (1982), we analyze an infinite horizon entry model where an incumbent may use its current price to signal its strength, in order to deter entry. In contrast with conventional limit pricing, we show the entry of weaker firms. We also provide necessary and sufficient...

We incorporate a search-theoretic model of imperfect competition into an otherwise standard model of asymmetric information with unrestricted contracts. We develop a methodology that allows for a sharp analytical characterization of the unique equilibrium and then use this characterization to...

In this paper I studied the optimal mechanism in selling information to decision makers with private prior knowledge about the payoff relevant state. When the underlying decision problem has a continuum of actions, the optimal mechanism will be a continuum menu of experiments with decreasing...

Pricing decisions are increasingly in the “hands” of artificial algorithms. Scholars and competition authorities have voiced concerns that those algorithms are capable of sustaining collusive outcomes more effectively than human decision makers. If this is so, then our traditional policy...
