Differential awareness, ambiguity, and incomplete contracts: a model of contractual disputes

We focus on aspects of differential awareness that give rise to contractual disputes. Parties to a contract are boundedly rational as the state space available to them is coarser than the complete state space. Hence, they may disagree as to which state of the world has occurred, and therefore as to what actions are required by the contract. Such disagreement leads to disputes. We show that the agents may prefer simpler less ambiguous contracts when facing potential disputes.
