1. A state that emerges when a resource is allocated by a design that correctly manifests the relative magnitude of the competing needs for it (i.e., fairness is achieved when each of the parties needing a given resource is appropriated a fraction of it that is proportional to each party’s relative need for it; e.g., when the needs are identical, fairness is accomplished by the appropriation of equal parts).
2. A state that emerges when all the participants in a contract (or an agreement) adhere to their parts in it (i.e., when each of the parties to an agreement deliver their part as stated in the agreement).
