We examine an entry-deterrence model in the commons. We investigate in which contexts asymmetric information among firms becomes welfare improving, and in which settings an uninformed regulator may prefer to assess and disseminate information about the available stock among firms.

In the context of first-price auctions with asymmetrically informed bidders, we show that risk aversion not only increases a player's bid, but also makes him less sensitive to the probability that other bidders are informed about his private valuation.
