The Chicago Boys were a group of Chilean economists who rose to prominence in the 1970s and 1980s. Most were educated at the University of Chicago Department of Economics under influential figures like Milton Friedman, Arnold Harberger, and Larry Sjaastad, or at its academic partner, the Pontificia Universidad Católica de Chile. After returning to Latin America, they assumed key roles as economic advisors in several South American governments, most notably the military dictatorship of Chile (1973–1990), where many attained the highest economic offices. Their free-market policies later influenced conservative governments abroad, including those of Ronald Reagan in the United States and Margaret Thatcher in the United Kingdom.
