This paper derives necessary and sufficient conditions for the existence of linear equilibria in the Rochet-Vila model of market making. In contrast to most previous work on the existence of linear equilibria in models of market making, we do not impose independence of the underlying random...

The existence of a linear equilibrium in Kyle's model of market making with multiple, symmetrically informed strategic traders is implied for any number of strategic traders if the joint distribution of the underlying exogenous random variables is elliptical. The reverse implication has been...

This paper considers a class of repeated signalling games to gain some intuitive insights into the effects and the desirability of modelling players in a dynamic game of incomplete information as being obstinate in the sense that their beliefs satisfy a support restriction. We demonstrate that...

The paper analyzes the canonical hold-up model of Hart and Moore (1988) under the assumption that the courts can verify delivery of the good by the seller. We show that the first best can be achieved using simple "option contracts" which give the seller the right to decide whether or not trade...

We examine the evolutionary foundations of common equilibrium refinement ideas for extensive form games, such as backward and forward induction, by examining the limiting outcome of an evolutionary process driven by stochastic learning and (rare) mutations. We show that the limiting outcome in a...

This paper introduces a class of signalling games with response intersection to discuss the informational efficiency of a monopolistic financial market. For these games a necessary and sufficient condition for the existence of a fully revealing sequential equilibrium outcomes is derived....

We show that, in environments with independent private values and transferable utility, a privately informed principal can solve her mechanism selection problem by implementing an allocation that is ex-ante optimal for her. No type of the principal can gain from proposing an alternative...

We provide a solution to the informed-principal problem in the independent private values setting with monetary transfers. The principal's private information creates signaling considerations that may distort the implemented allocation. We show that there is no distortion: all principal types...
