Regulation is frequently less successful than it could be, largely because the allocation of authority to regulatory institutions, and the relationships between them, are misunderstood. As a result, attempts to create new regulatory programs or mend under-performing ones are often poorly designed. In their new book, Reorganizing Government: A Functional and Dimensional Framework, Alejandro Camacho and Robert Glicksman explain how past approaches have failed to appreciate the full diversity of alternative approaches to organizing governmental authority.
