Since the first edition published in 1999 with editor Paul Sabatier, Theories of the Policy Process has served as the quintessential gateway to the field of policy process research for students, scholars and practitioners alike. This enduring and well-regarded volume provides a forum for the creators of, or scholars with deep expertise in, the most established and widely used theoretical frameworks to present the basic propositions, empirical evidence, latest updates, and promising directions for future research. This brief but comprehensive volume covers such classics as Multiple Streams (Zahariadis), Punctuated Equilibrium (Jones et al), Advocacy Coalition Framework (Jenkins-Smith et al.), Institutional Analysis and Development Framework (Ostrom et al.), Policy Diffusion (Berry & Berry), and Social Construction and Policy Design (Schneider et al). This thoroughly updated third edition, with new editor Christopher M. Weible, includes a new introduction on the trajectories and needs of public policy research and two new chapters, Policy Feedback (Mettler and SoRelle) and Narrative Policy Framework (McBeth et al). A revised chapter presents a comparative analysis and evaluation of the frameworks included in this edition (Cairney & Heikkila), and a new conclusion looks at future directions and emerging areas in the field.
