Thorstein Bunde Veblen (born Torsten Bunde Veblen; July 30, 1857 – August 3, 1929) was an American economist and sociologist. He was famous as a witty critic of capitalism.

Veblen is famous for the idea of "conspicuous consumption." Conspicuous consumption, along with "conspicuous leisure," is performed to demonstrate wealth or mark social status. Veblen explains the concept in his best-known book, The Theory of the Leisure Class (1899). Within the history of economic thought, Veblen is considered the leader of the institutional economics movement. Veblen's distinction between "institutions" and "technology" is still called the Veblenian dichotomy by contemporary economists.
