The impossibility of speculative trade result (Milgrom and Stokey, 1982) provokes the questions why traders care about their private information, if they cannot profit from it and how the aggregate information can then be reflected in REE prices. This paper answers these questions by analyzing a...

This paper considers an agency contracting with multiple tasks. The agent is privately informed on some tasks, but he must gather information on the other. We show that depending on the cost to gather information, task assignment is employed as an instrument to induce information gathering, or...

A review of the literature on cost sharing solutions for the minimum cost spanning tree problem is proposed, with a particular focus on the folk and Kar solutions. We compare the characterizations proposed, helped by some equivalencies between sets of properties.

Restricting the analysis to general 2×2 coordination games, this article shows how under certain conditions, it is highly likely that individuals coordinate on a (pay-off) efficient through risk inferior convention. This contrasts with other equilibrium refinement criteria, such as risk...

The topic is two-fold. First, we prove the convexity of Owen's Airport Profit Game (inclusive of revenues and costs). As an adjunct, we characterize the class of 1-convex Airport Profit Games by equivalent properties of the corresponding cost function. Second, we classify the class of 1-convex...

The interaction between a sophisticated player and a fictitious player is analyzed and applied to the problem of optimal enforcement. An adaptive potential offender myopically responds to the history of past enforcement. How can a sophisticated enforcement official take advantage of this...
