George J. Stigler, one of the most influential economists of the 20th century, won the Nobel Prize in Economic Sciences in 1982 “for his seminal studies of industrial structures, functioning of markets, and causes and effects of public regulation.” His research upended the idea that government regulation was effective at correcting private-market failures. Stigler introduced the idea of regulatory capture, in which regulators could be dominated by special interests. These regulators would work for the benefit of large, monied organizations rather than the public good. Catch up on ProMarket's coverage of his legacy.
