Stephen W. Salant (born c. 1945) is an economist who has done extensive research in applied microeconomics (mostly in the fields of natural resources and industrial organization). His 1975 model of speculative attacks in the gold market (with Dale Henderson) was adapted by Paul Krugman and others to explain speculative attacks in foreign exchange markets. Hundreds of journal articles and books on financial speculative attacks followed. In industrial organization, he has contributed to the literatures on horizontal mergers, price discrimination, durable goods monopoly, and cartels.
