JamesMarch ranks as one of the founders ofmodern organization theory. His early work with Nobel laureate Herbert Simon, resulting in the book Organizations (March and Simon, 1958) served in many ways to define the field of organization theory, being the first attempt at systematizing insights relative to organizational phenomena. The book was followed up in 1963 with a book co-authored with Richard Cyert entitled A Behavioural Theory of the Firm (Cyert and March, [1963]1992). The latter book is of particular interest as an early process perspective in economic organization theory.
