James Douglas Montgomery (born April 13, 1963) is professor of sociology and economics at the University of Wisconsin–Madison.
He has applied game-theoretic models and non-monotonic logic to present formal analysis and description of social theories and sociological phenomena.
His paper is a major contribution towards formalization of social theories and sociological interpretation of game theories since he presents a repeated-game model in which the players are not individuals (as traditionally conceived in economic models) but assume social roles such as a profit-maximizing "businessperson" and nonstrategic "friend" (Montgomery, 1999).
[1] In 1992, Montgomery explored the role of “weak ties”, which he defined as non-frequent and transitory social relations, in labor market.
working on integrating non-monotonic logic with social network analysis in the context of sociological theories.
