A profit maximising auctioneer can provide a public good to a group of agents. Each group member has a private value for the good being provided to the group. We investigate an auction mechanism where the auctioneer provides the good to the group, only if the sum of their bids exceeds a reserve...

A profit-maximizing auctioneer can provide a public good to at most one of a number of groups of agents. The groups may have non-empty intersections. Each group member has a private value for the good being provided to the group. We investigate an auction mechanism where the auctioneer provides...

We consider the effect of asymmetric information on price formation process in a financial market where private information is held by a market maker. A Byesian game is proposed in which there is price competition between two market makers with two different information partition.

We present new conditions that guarantee the existence of mechanism with a unique or essentially unique equilibrium in auction and public goods problems with quasi-linear utility functions. These conditions bear only on the information structures of the agents.

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...

It is common practice for firms to pool their expertise by forming parterships such as joint ventures and strategic alliances. A Central organizational problem in such parterships is that managers may behave noncooperatively in order to advance the interests of their parent firms. We ask whether...

Ths authors consider a first-price auction when the ranking of bidders' private valuations is common knowledge among bidders. This new informational framwork is motivated by several applications, from procurement to privatization. It induces a particular asymmetric auction model with affiliated...

The authors exhibit an efficient auction (i.e., an auction that maximizes expected surplus conditional on all private and public information). In the case of private value, it is well-known that the Vickrey auction (for one good) or its Groves-Clark extension (for multiple goods) is efficient in...

Consider an auction in which potential bidders must sink an entry investment before learning their values. Suppose the auction designer can make the bidders learn their value before entry. Such early information will induce screening of high-value bidders, and it will give rise to information...
