1. Introduction to Theories of Public Policy
Outline
Uses of Models
Types of Models

2. Dye: Uses of Models
Simplify and clarify our thinking about politics and public policy
Identify important aspects of policy problems
Help us to communicate with each other by focusing on essential features of political life
Direct our efforts to understand public policy better by suggesting what is important and unimportant
Suggest explanations for public policy and predict its consequences

3. 1. What constitutes Public Policy?
2. Stages in Public Policy Process
3. Models of the Policy Process
4. Implications/Assumptions

4. 1. Institutionalism Public policy as institutional output
Who: executive, legislative, and judicial branches
How: policy is authoritatively determined, implemented, and enforced by these institutions (legitimacy, universality, and coercion)
Implications/assumptions: individuals have little impact; structure/design affects outcomes

5. 2. Process Model Public policy as political activity
Who: voters, interest groups, legislators, presidents, bureaucrats, judges
How: ID problem, set agenda, formulate policy proposals, legitimate policies, implement policies, evaluate policies
Implications/assumptions: who participates has a critical or determinant impact on the process

6. 3. Group Theory Public policy as group equilibrium
Who: interest groups, their allies in government
How: struggle among interest groups with legislature/executive as referee to manage group conflict and establish rules of the game
Implications/assumptions: groups will always join to press for particular issues, all interests will have an opportunity for representation

7. 4. Elite Theory Public policy as elite preference
Who: elites that have power, ability to allocate value
How: implementation of the preferences and values of the governing elite; public officials merely carry out policies decided on by the elites
Implications/assumptions: public is apathetic elites agree upon norms; political action is merely symbolic; protects the status quo

8. 5. Rationalism Public policy as maximum social gain
Who: decision makers (all social, political, economic values sacrificed or achieved by a policy choice) irrespective of dollar amount (Bentham, Mills)
How: select policy alternative(s) that allows gains to society to exceed benefits by the greatest amount
Implications/assumptions: assumes that the values preferences of the society as a whole can be known and weighted

9. 6. Incrementalism Public policy as variations on the past
Who: policy makers, legislators, others with a stake in ongoing programs or problems
How: continuation of past government activities with only incremental modifications
Implications/assumptions: accepts the legitimacy of established programs; fear of unintended consequences; sunk costs in other programs may minimize the opportunities for radical change

10. 7. Game Theory
Public policy as rational choice in competitive situations
Who: players/decision makers who have choices to make and the outcome depends on the choice made by each (assumes rationality in making choices)
How: each player has goals and resources, a strategy developed given possible moves of opponent, and payoff values that constitute the outcomes of the game
Implications/assumptions: repeated plays should lead to better policy outcomes

11. 8. Public Choice
Public policy as collective decision making by self-interested individuals
Who: rational self-interested individuals will in both politics and economics cooperate to achieve their goals
How: individuals come together in politics for their own mutual benefit; government must respond to market failures
Implications/assumptions: individuals have sufficient information to know what is in their best interest

12. 9. Systems Theory Public policy as system output
Who: individuals, groups, or nations depending upon the scope of the problem
How: environment may stimulate inputs into political system, producing outputs and feedback
Implications/assumptions: systems implies an identifiable set of institutions and activities in society that functions to transforms demands into authoritative decisions requiring the support of the whole society; implies that the elements of the system are interrelated, that the system can respond to forces in its environment, and that it will do so to preserve itself

13. 10. Kingdon-Garbage Can Model
Who: participants inside and outside government
How: choice opportunity is a garbage can into which various kinds of problems and solutions are dumped by participants as they are generated; policy outcomes are a function of the mix of the garbage: problems, solutions, participants, and participant resources in the can and how the can is processed
Implications/assumptions: each of the actors and processes can operate either as an impetus or as a constraint; streams operate largely independent of one another
