This paper considers the situation where two products are sold by the same seller, but to disjoint sets of potential buyers. Externalities may arise from each market outcome to the other. The paper examines the nature of the seller's optimal mechanism, and, for example in the case of positive...

Three designs of auctions with quality thresholds are considered. The quality threshold is not known with certainty by the bidders. In one scheme, quality plans submitted by potential bidders are evaluated first and price bids for only those plans that have been approved are invited. The second...

The effect of limited liability on debt contracts has been analysed as creating the possibility of credit rationing and hence inefficiently low levels of investment. In this paper we instead focus on restrictions on the use of debt finance to avoid moral hazard problems but which add...

This paper studies a game of strategic experimentation with two-armed bandits whose risky arm might yield a payoff only after some exponentially distributed random time. Because of free-riding, there is an inefficiently low level of experimentation in any equilibrium where the players use...

We consider the employment relation within firms with reference to investment in human capital. Although the firm knows the future value of the worker's human capital to the worker, the worker only finds this out after the training is complete. Both moral hazard and adverse selection problems...

Consider two agents who learn the value of an unknown parameter by observing a sequence of private signals. Will the agents commonly learn the value of the parameter, i.e., will the true value of the parameter become approximate common-knowledge? If the signals are independent and identically...
