Externalities
Costs or benefits of an economic transaction borne by parties outside the transaction — the mechanism through which individually rational AI adoption decisions produce systemically harmful outcomes that no participant intended.
An externality is a cost or benefit of an economic transaction borne by parties who are not part of the transaction. Air pollution from a factory is the classic example: the firm captures the benefits of production, the customers capture the benefits of the product, and the surrounding community bears costs in health and environmental quality that do not appear in the transaction's price. Because externalities do not appear in the optimization calculus of the transaction's participants, rational decisions produce systematically inefficient outcomes — too much pollution, too little investment in public goods, too much of whatever generates negative spillovers and too little of whatever generates positive ones. Becker's framework applies externality analysis to domains beyond the market, including education, family formation, and now the AI transition's production of structural effects no individual participant intended.
