In this fourth edition of his ground-breaking work, Herbert A. Simon applies his pioneering theory of human choice and administrative decision-making to concrete organizational problems. To commemorate the fiftieth anniversary of the book's original publication, Professor Simon enhances his timeless observations on the human decision-making process with commentaries examining new facets of organizational behavior. Investigating the impact of changing social values and modern technology on the operation of organizations, the new ideas featured in this revised edition update a book that has become a worldwide classic. Named by Public Administration Review as "Book of the Half Century", "Administrative Behavior" is considered one of the most influential books on social science thinking, and was referred to by the Nobel Committee as "epoch-making". Written for managers and other professionals who wish to understand the decision-making processes at the heart of organization and management, it is also essential reading for students in business and management, economics, sociology, psychology, computer science, government, and law.
