Ronald Coase
The Nature of the Firm, 1937
The Boundaries of the Firm: A firm will expand until the costs of organizing an extra transaction within the firm become equal to the costs of carrying out the same transaction by means of an exchange on the open market.
The Problem of Social Cost, 1960
Reciprocal Nature of Harm: Coase argued that externalities (like pollution) are reciprocal. A factory polluting a neighborhood harms the residents, but stopping the factory harms the production of the firm.
The Importance of Institutions: In the real world, transaction costs are never zero. Therefore, institutional arrangements (who owns what rights) determine economic efficiency.
The Complexity Lens: The prosperity of a society depends not just on the emergence of talent, but on whether its institutional structure can minimize transaction costs to allow synergy to emerge naturally.
