Ronald Coase's 1937 insight was that these costs — finding the right person, negotiating terms, monitoring compliance — are real and substantial, often consuming nearly half of economic activity in developed economies. When transaction costs are high, it becomes cheaper to organize activities within a firm under managerial direction than to contract for them on the market.
