Contracts are drafted in a common language. Nevertheless, the principal and the agent may ultimately disagree about the terms of the contract that apply ex post. We presume that both parties are ambiguity averse and for tractability reasons that their preferences take a recursive constant absolute risk averse (RCARA) form. We consider various dispute resolution regimes and analyze how the optimal dispute resolution regime depends on the ambiguity attitudes of the parties. We also provide an axiomatization of the class of RCARA preferences.application/pdfen-AU© 2018 Elsevier IncLinguistic ambiguityPrincipal agent problemState-contingent versus output contingentcontracts201810.1016/j.geb.2018.02.0082020-11-23
