Michael D. Cohen (1945–2013) was a distinguished political scientist, organizational theorist, and public administration scholar, best known for revolutionizing the understanding of organizational decision-making through the Garbage Can Model of Organizational Choice. Developed with James G. March and Johan P. Olsen, this influential model challenged the traditional assumption that organizations always make rational and orderly decisions. Instead, Cohen demonstrated that decisions in complex institutions often emerge from the unpredictable interaction of problems, solutions, participants, and choice opportunities, making ambiguity and uncertainty central features of organizational life.
This article provides a comprehensive overview of Michael D. Cohen’s life and intellectual contributions, covering his biography, Garbage Can Model, Organized Anarchy, organizational learning, complexity theory, public policy, institutional analysis, key concepts, major publications, criticisms, and enduring legacy. It also explores how Cohen’s ideas transformed public administration, governance, organizational sociology, behavioral political science, and policy analysis, influencing research on bureaucracies, universities, public institutions, and complex adaptive systems. Whether you are preparing for UPSC, State PCS, UGC-NET Public Administration, Political Science, Organizational Behaviour, Management, Sociology, or Competitive Examinations, this guide offers a clear, engaging, and exam-oriented understanding of one of the most influential thinkers in modern organizational theory.
