The third edition of Contemporary Regulatory Policy brings this classic text completely up to date-reflecting more than a decade of policy changes and including an entirely new chapter on food safety regulation. Beyond their focus on seven key policy arenas, the authors confront the broad problems of partisan polarization and congressional gridlock. They also consider the significance of unilateral policy actions by President Obama and how these initiatives may be vulnerable to change under President Trump. Recognizing that no single theory can sufficiently explain regulatory politics, they offer a comprehensive set of tools for understanding the world of regulatory policy today.
