The institutional economist who built the analytical machinery to answer why firms exist—whose transaction cost framework, centered on bounded rationality, opportunism, and asset specificity, now predicts with uncomfortable precision what AI is doing to every organizational boundary in the economy.
In 1937, Ronald Coase asked a question so obvious that the entire economics profession had overlooked it: why do firms exist at all, if markets are as efficient as claimed? Oliver Williamson spent the next five decades giving that question its teeth. His framework—
transaction cost economics—specified exactly which characteristics of a transaction determine whether it should be governed through markets, hierarchies, or the hybrid forms between them, and it did so with a precision that won him the 2009 Nobel Prize in Economic Sciences. The framework rests on three variables:
asset specificity, the degree to which assets lose value when redeployed outside a particular relationship;
opportunism, the assumption that agents will exploit informational advantages when they can; and bounded rationality, the recognition, borrowed from
Herbert Simon, that humans cannot foresee all contingencies or write complete contracts. From these three variables Williamson derived a single prediction of remarkable generality: as asset specificity
