A consistent pair specifies a set of "rational" strategies for both players such that a strategy is rational if and only if it is a best reply to a Bayesian belief that gives positive probability to every rational strategy of the opponent and probability zero otherwise. Although the idea...

We briefly survey several insights about value and revenue maximization in multi-object auctions and apply them to the German (and Austrian) UMTS auction. In particular, we discuss in detail the exposure problem that caused firms in Germany to pay almost Euro 20 billion for nothing.

Concerns for relative performance are integrated into a model of contractual renegotiation in bilateral trade. It is shown that concerns for relative performance do never impede efficient trade. Moreover, conditional on renegotiation to occur, concerns for relative performance tend to mitigate...

The paper offers a concise proof of a rule attributed to Alfred Marshall concerning the own-price elasticity of a firm's derived factor demand. The derivation uses the implicit function theorem.

Optimal rank-order tournaments have traditionally been studied using a first-order approach. The present analysis relies instead on the construction of an "upper envelope" over all incentive compatibility conditions. lt turns out that the first-order approach is not innocuous. For example, in...
