Abstract
The economic approach to sociology accepts purposeful behavior at the level of the individual, but rejects functionalism at the group level. It posits rationality or the attempt to maximize utilities. In general, it assumes stable preferences and selfishness. Here, the rational action model of human behavior is applied to the division of labor, exchange, and team production; to social norms and deviant behavior; to rebellions and revolutions. A focus on inequalities in resource endowments and motivation together with insights from the logic of collective action provide the typic all point of departure in these analyses.
