Contract theory studies how people and organizations develop legal agreements in uncertain conditions with unknown factors and information asymmetry. It applies to both multi-party negotiations and contracts created by a single entity to specify agreement details. Ideally, a contract specifies all party responsibilities and requirements unambiguously to prevent disputes, but misunderstandings may still occur. Models within contract theory examine risks like moral hazard where a party acts in bad faith by withholding or misrepresenting information. Other models consider adverse selection where one party lacks risk information and signaling where a party conveys qualifying information. Contract theory applies game theory, which analyzes negotiation, conflict and cooperation between entities. Key questions involve why individuals make decisions and how individual decisions impact others.
