Robert D. Putman
Robert David Putnam is a political scientist and professor of public policy at the Harvard University John F. Kennedy School of Government. He is also visiting professor and director of the Manchester Graduate Summer Programme in Social Change, University of Manchester (UK). Putnam developed the influential two-level game theory that assumes international agreements will only be successfully brokered if they also result in domestic benefits. His most famous (and controversial) work, Bowling Alone, argues that the United States has undergone an unprecedented collapse in civic, social, associational, and political life (social capital) since the 1960s, with serious negative consequences.
