By using general information structures and precision criteria based on the dispersion of conditional expectations, we study how oligopolists' information acquisition decisions may change the effects of information sharing on the consumer surplus. Sharing information about individual cost...

In a relatively recent paper, Gehrig and Stenbacka (Eur Econ Rev 51, 77-99, 2007) show that information sharing increases banks’ profits to the detriment of creditworthy entrepreneurs in a model of a banking duopoly with switching costs and poaching. They restrict their analysis to the case in...

This paper studies the relationship between the auctioneer's provision of information and the level of competition in private value auctions. We use a general notion of informativeness which allows us to compare the efficient with the (privately) optimal amount of information provided by the...

We study a situation in which an auctioneer wishes to sell an object to one of N risk-neutral bidders with heterogeneous preferences. The auctioneer does not know bidders’ preferences but has private information about the characteristics of the ob ject, and must decide how much information to...

How much information does an auctioneer want bidders to have in a private value environment? We address this question using a novel approach to ordering information structures based on the property that in private value settings more information leads to a more disperse distribution of buyers’...

The paper deals with a bilateral accident situation in which victims have heterogeneous costs of care. With perfect information,efficient care by the injurer raises with the victim's cost. When the injurer cannot observe at all the victim's type, and this fact can be verified by Courts,...
