Theories of the Policy Process provides a forum for the proponents of several of the most promising and widely used theoretical frameworks to present the basic propositions of their frameworks, to assess the empirical evidence that has developed, and to discuss promising directions for future research. The first edition contained analyses of Institutional Rational Choice (Ostrom), Multiple Streams (Zahariadis), Punctuated Equilibrium (Jones et al.), Advocacy Coalition Framework (Sabatier and Jenkins-Smith), and Policy Diffusion (Berry and Berry). The second edition revises these and adds new chapters on Social Construction and Policy Design (Schneider et al.) and Policy Networks (Adam and Kriesi). It also contains a much more serious analysis of the European literature relevant to each of the frameworks. Finally, the new edition contains a revised chapter by Edella Schlager, presenting a comparative analysis and evaluation of the relevant frameworks, and a concluding chapter by the editor suggesting a number of strategies for improving the state of theorizing in this field.
