This paper presents a model of price screening for goods with network effects, by a monopoly seller, and by an entry-deterring monopolist. These products are used in variable quantities by heterogeneous customers, the magnitude of network effects is influenced by gross consumption, rather than...

In principal-agent settings with moral hazard, the fact that agents are altruistic vis-a-vis third parties (e.g. their family) modifies incentive costs. We derive sufficient conditions for the principal to benefit from altruism. They bear on how altruism affects the agent's marginal rate of...

Consider the case of a firm with private valuation information bargaining with a supplier over the price and quantity of a good. If the firm and the supplier bargain directly, the bargaining outcome may not yield a first-best outcome due to the presence of information rents. The question we...

Empirical evidence shows that macroeconomic fundamentals have little explana-tory power for nominal exchange rates. On the other hand, the recent “microstruc-ture approach to exchange rates” has shown that most exchange rate volatility at short to medium horizons is related to order flows....

We examine the impact of public information in an economy where agents also have diverse private information. Our work builds on seminal contributions by Townsend (1983) and Phelps (1983), and more recently Woodford (2002), which emphasized the importance of higher-order beliefs – that is,...

Sellers benefit on average from revealing information about their goods to buyers, but the incentive to exaggerate undermines the credibility of seller statements. When multiple goods are being auctioned, we show that ordinal cheap talk, which reveals a complete or partial ordering of the...

We study optimal nominal demand policy in a flexible price economy with monopolistic competition where firms have imperfect common knowledge about the shocks hitting the economy. Information imperfections emerge endogenously because firms are assumed to have finite (Shannon) capacity to process...

Existence of monotone pure strategy equilibrium is established in the discriminatory and uniform S + a-th price (a in [0, 1]) auctions of S identical objects when bidders are risk-neutral with independent signals. The model requires discrete price / quantity grids and allows for...

A possible view of the role of an adjudicator is that it is to obtain the information that is needed to apply a well-articulated legal rule. That is, the task of an adjudicator in a case is to gather and verify the information that is called for to employ a legal rule, but that once the required...

We investigate the issue of implementation via individually rational ex-post budget-balanced Bayesian mechanisms. We demonstrate that all social choice rules that generate a nonnegative ex-ante surplus, including ex-post efficient ones, can generically be implemented via such mechanisms. The...
