'In skillfully presenting new theoretical and empirical findings, Christopher Carrigan persuasively challenges long-standing principles about how to organize the many regulatory authorities that oversee business behavior. This innovative book represents the most definitive treatment of the opportunities and challenges involved in structuring the missions and jurisdictions of government agencies. With careful analytical execution and often counterintuitive insight, Carrigan offers a major advance in the study of regulatory politics and public administration, with critical insights for scholars and policymakers alike.'
