Market societies have created more wealth, and more opportunities for more people, than any other system of social organization in history. Yet we still have a rudimentary understanding of how markets themselves are social constructions that require extensive institutional support. This groundbreaking work seeks to fill this gap, to make sense of modern capitalism by developing a sociological theory of market institutions. Addressing the unruly dynamism that capitalism brings with it, leading sociologist Neil Fligstein argues that the basic drift of any one market and its actors, even allowing for competition, is toward stabilization.
