Under demand uncertainty, a risk-averse seller adopts marginal-cost pricing when clients are homogenous. When the clients are heterogeneous, the optimal unit price tends to move towards marginal cost as the seller's risk aversion increases and equals marginal cost if the seller is infinitely...

We present a diagrammatic and step-by-step analysis of price signaling quality. Because quality is a continuum on the real positive line, out-of-equilibrium beliefs need not be specified, i.e., every positive price is a positive outcome in equilibrium. We first study the behavior of the monopoly...

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...

Market definition is an essential ingredient to competitive and regulatory analysis. Yet, there is significant disparity regarding the definition of the relevant geographic market for high-capacity circuits, commonly referred to as Special Access services. Given the present debate over expanding...

This paper studies two-part tariffs with explicit consideration of cost uncertainty and risk aversion. It finds that firms charge a risk premium over expected marginal cost for each unit they sell. This pricing rule is socially optimal if and only if the modeled market is fully covered in...

We study the informational role of prices. To that end, we consider the framework of a dominant firm with a competitive fringe. When the competitive fringe is large enough, there exists a unique fully revealing equilibrium, in which the price conveys full information about the quality of the...

This paper investigates a stepwise tax/subsidy structure on a monopoly practicing quantity discounts. It covers four tax/subsidy systems: uniform and non-uniform schemes, each under specific and ad valorem regimes. The effects of an exogenous change in a tier's tax rate on the optimal tier sizes...
