The contractual or nexus of contracts theory df the firm, which is wid
ely accepted in financial economics and legal theory, has a normative
structure that can provide a framework for identifying and analyzing m
any business ethics problems and for devising solutions to those probl
ems. Specifically, the contractual theory of the firm focuses on the n
eed to safeguard the assets that each constituency brings the nexus of
contracts, and many ethical problems result from inadequate safeguard
ing of the assets of a particular constituency. Business ethics proble
ms can be identified within the contractual framework as wrongful harm
s, misallocations, and misappropriations. Solutions include tort remed
ies, the expansion of management responsibility, and political action,
including regulation. However, the theory of the firm does not addres
s all business ethics problems, particularly those involving large eco
nomic and social forces outside the firm. Nevertheless, the contractua
l theory has sufficient explanatory power that it should be seriously
considered by researchers in business ethics.
