We show that under standard assumptions a Tullock contest with asymmetric information has a pure strategy Bayesian equilibrium. Moreover, two-player common-value Tullock contests in which one of the players has an information advantage have a unique equilibrium. In equilibrium both players exert...

Under standard assumptions about players'cost functions, we show that a Tullock contest with asymmetric information has a pure strategy equilibrium. Next we study Tullock contests in which players have a common value and a common state-independent linear cost function. A two-player contest in...

We study a general model of common-value second-price auctions with differential information. We show that one of the bidders has an inform tion advantage over the other bidders if and only if he possesses dominantstrategy. A dominant strategy is in fact unique and is given by the conditional...

We study a class of common-value second-price auctions with differential information. This class of common-value auctions is characterized by the property that each player's information set is connected with respect to the common value. We show that the entire class is dominance solvable,...

We study upper semi-continuity of the private and coarse core and the Walrasian expectations equilibrium correspondences for economies with differential information, with Boylan (1971) topology on agents’ information fields. Copyright Springer-Verlag Berlin/Heidelberg 2005

We study the core and competitive allocations in exchange economies with a continuum of traders and differential information. We show that if the economy is "irreducible", then a competitive equilibrium, in the sense of Radner (1968, 1982), exists. Moreover, the set of competitive equilibrium...

We study how changes in the information available to the players of a symmetric common-value Tullock contest with incomplete information affect their payoffs and their incentives to exert effort. For the class of contests where players' state dependent cost of effort is multiplicative, we show...
