摘要：In the neoclassical model firm, identified with a perfectly rational entrepreneur, is reduced to the function
of production and is mechanically adapted to its environment. Reconsidering some hypothesis of this model
led to a contractual approach of firm, based upon concepts and results of game theory and information
economics.
Contractual theories have as an objective to describe relations of exchange between agents, considering
institutional and informational restrictions of their evolution background. The most known contractual
theories are: transaction costs theory, which is based on the notion of transaction, positive theory of
agency, which analyses divergences of interest between partners in the frame of collaboration and the cost
of these conflicts, and theory of property rights which emphasizes the structure of property rights.
