This volume is a one—of—a—kind contribution to applied social science and the product of a long collaboration between an established, interdisciplinary sociologist and a successful banking executive. Together, Neil Smelser and John Reed use a straightforward approach to presenting substantive social science knowledge and indicate its relevance and applicability to decision—making, problem—solving and policy—making. Among the areas presented are space—and—time coordinates of social life; cognition and bias; group and network effects; the role of sanctions; organizational dynamics; and macro—changes associated with economic development. Finally, the authors look at the big picture of why society at large demands and needs social—science knowledge, and how the academy actually supplies relevant knowledge.
