The emergence of sociology from political economy in the United States: 1890 to 1940.

Professional sociology in the U.S. began as a field area within economics, but gradually emerged as a separate discipline. Using new data on joint meetings and the separation of departments, I track interdisciplinary relations through three phases: sponsorship (1890-1905), collaboration (1905-1940), and disengagement (post-1940). In the early years, sociology was mostly a branch of economics departments. With the formation of the American Sociological Society, relations with economics began to be more characterized by professionally autonomous collaboration. The 1920s saw a large wave of sociology departments separating from economics. Still, joint annual meetings (including joint presidential addresses) remained the norm until 1940. Paradigmatic conflict between institutional and neoclassical economists was the major force that sustained the economics-sociology collaboration. As institutionalism faded from the scene in the late 1930s, so went interdisciplinary contact.
