Stewart Macaulay teaches contracts at the University of Wisconsin Law School and is interested in the part the legal system plays in implementing, regulating, and hindering economic relationships, and how it does these things. This book is a descriptive analysis of organizational change that has resulted from automobile dealers' attempts to find a legal remedy for what they consider unfair practices of the manufacturers. It advances our understanding of the limitations and the positive functions of formal rules in the regulation of human conduct, and shows how informal procedures can develop as a result of pressure for changes in the formal rules.
