Lignite price negotiation between opencast mine and power plant as a two-stage, two-person, cooperative, non-zero sum game. Based on the simple model of the lignite deposit the methodology of finding the optimal solution for bilateral monopoly (BM) of lignite mine and power plant is shown taking...

We analyse how consumer heterogeneity affects buying behaviour and the monopoly pricing of a network good and its usage. Under perfect information, sufficiently high heterogeneity yields a unique equilibrium, and the unit price is increasing in heterogeneity. Under incomplete information, we...

Discussion of "The Pricing Behavior of Firms in the Euro Area: New Survey Evidence" by S. Fabiani, M. Druant, I. Hernando, C. Kwapil, B. Landau, C. Loupias, F. Martins, T. Mathä, R. Sabbatini, H. Stahl, and A. Stockman (2004); Presented at the Inflation Persistence Network (IPN) Conference on...

Consider a revenue-maximizing seller who can sell an object to one of n potential buyers. Each buyer either has hard information about his valuation (i.e., evidence that cannot be forged) or is ignorant. The optimal mechanism is characterized. It turns out that more ignorance can increase the...

In many long-term relationships, parties may be reluctant to reveal their private information in order to benefit from their informational advantage in the future. We point out that the strategic use of debt by an uninformed party induces another party to reveal private information. Our...

We study the welfare effects of ambiguous product information for a buyer with alpha-max-min preferences and a price-setting seller. The buyer privately receives information about her valuation. We show that both can benefit when this information is ambiguous, and we characterize all possible...

We present a model of a discriminatory price auction in which a large bidder competes against many small bidders, followed by a post-auction resale stage in which the large bidder is endogenously determined to be a buyer or a seller. We extend results on first-price auctions with resale to this...

In this note we show that the equilibrium characterized by Biais, Martimort and Rochet (Econometrica, 2000) could have been characterized by direct mechanisms even if the Revelation Principle does not apply in their setting. The use of more sophisticated mechanisms, such as menus, was not necessary.

We consider a multi-dimensional procurement problem in which sellers have private information about their costs and about a possible design flaw. The information about the design flaw is necessarily correlated. We solve for the optimal Bayesian procurement mechanism that implements the efficient...
