Abstract:
This paper provides a precise and critical rereading of theories, developed before the 1990s, able to justify why privatization has been considered as a central component of transition in post-socialist countries, mainly the theory of property rights, managerial theories of the firm, the positive theory of agency. It highlights their difficulties to fully explain the inefficiency of state enterprises and the superiority of private corporations. It concludes on theoretical missing links, pertaining to the role of state, incompleteness of contracts, laws, uncertainty and entrepreneurship.
