Policy Cycle
Policy cycle: Agenda → Formulation → Adoption → Implementation → Evaluation
Policy Cycle
Five stages all public policies move through
Agenda setting: issue gets attention. Formulation: solutions designed. Adoption: officially approved. Implementation: agencies execute. Evaluation: effectiveness assessed. Cycle can repeat.

Iron Triangle
Iron Triangle: agency + committee + interest group — all benefit each other
Iron Triangle
Three actors who dominate policy in any given area
Congressional committee writes the law. Executive agency implements it. Interest group lobbies for it and provides expertise. Each benefits the others — a closed, self-reinforcing loop.

Legislative Process
How a bill becomes law: committee → chamber → conference → President
Legislative Process
The path from bill introduction to presidential signature
Introduced → committee → full chamber vote → other chamber repeats → conference committee if versions differ → President signs or vetoes → 2/3 override needed.

Administrative Agencies
Regulatory agencies are quasi-legislative, quasi-judicial, and executive all at once
Administrative Agencies
Federal agencies combine all three governmental powers
They make rules (legislative), enforce them (executive), and adjudicate disputes (judicial). Examples: EPA, SEC, FDA, FCC. Criticized for combining powers the Constitution separates.

Cost-Benefit Analysis
Cost-benefit analysis: weigh all costs and benefits to find the most efficient policy
Cost-Benefit Analysis
The standard tool for evaluating whether a policy is worth it
Add up all expected benefits (in dollar terms), subtract all expected costs. If benefits > costs → implement. Criticized for difficulty of monetizing non-market goods (human life, environment). Required for major federal regulations.

Agenda Setting
Agenda setting: media and interest groups determine what issues government addresses — first step of policy
Agenda Setting
How issues get onto the government's to-do list
Kingdon's streams model: problems stream (conditions become problems), policy stream (solutions exist), politics stream (political will) must converge to open a 'policy window.' Issue salience: media coverage → public attention → political pressure. Crises open windows: 9/11 → Homeland Security, financial crisis → Dodd-Frank.

Incrementalism
Incrementalism: policy changes happen in small steps, not revolutionary leaps — status quo has enormous power
Incrementalism
Why radical policy change is rare — even when desired
Lindblom: policymakers lack information and time for comprehensive analysis → make small adjustments to existing policy (muddling through). Status quo bias: existing programs have organized beneficiaries who defend them. Sunk costs: previous investments make change harder. Path dependence: early choices constrain later options.

Regulatory Capture
Regulatory capture: regulated industries gain control of the agencies that regulate them
Regulatory Capture
When the regulator starts serving the regulated
Stigler's capture theory: over time, regulated industries use resources and expertise to influence regulatory agencies. Revolving door: agency staff move to industry jobs and vice versa. Industry has more sustained interest in regulatory decisions than dispersed public. Result: regulations serve industry interests rather than public interest.

States as Policy Laboratories
Federalism and policy: states as laboratories of democracy — policy experiments spread nationally
States as Policy Laboratories
How federalism enables policy innovation
Brandeis called states 'laboratories of democracy.' Policy innovations often start in states before going national: Massachusetts healthcare → ACA, California auto emissions standards, state minimum wage experiments. Race to the bottom: states may cut regulations to attract business. Race to the top: states compete to attract talent with better services.

Public Goods
Public goods: non-excludable + non-rival. Free rider problem → government must provide them.
Public Goods
Why markets underprovide certain goods — requiring government intervention
Non-excludable: can't prevent people from using it (national defense, clean air). Non-rival: one person's use doesn't reduce availability for others. Free rider problem: if can't exclude, people won't pay voluntarily → market won't produce enough → government must provide and fund through taxes.

Externalities and Policy
Externalities require government: negative (pollution tax/regulation), positive (education subsidy)
Externalities and Policy
When markets fail to account for effects on third parties
Negative externality: cost borne by third parties not in the transaction. Market overproduces → Pigouvian tax, cap-and-trade, regulation to internalize cost. Positive externality: benefit flows to third parties. Market underproduces → subsidy, public provision. Education: benefits beyond the individual → subsidized.

Policy Implementation
Implementation gap: what policy says vs what actually happens on the ground — street-level bureaucrats
Policy Implementation
The gap between policy intent and policy reality
Lipsky's street-level bureaucrats: teachers, police, social workers exercise significant discretion implementing policy. Implementation failure: unclear mandates, inadequate resources, multiple veto points, principal-agent problems. Top-down model: central control. Bottom-up: local actors adapt policy to context.

Policy Evaluation Criteria
REIA — Results, Efficiency, Impact, Adequacy
Four criteria for evaluating whether a public policy is working
Good evaluation asks if the program worked, at what cost, for whom, and whether the problem is solved
Effectiveness: did the program achieve its stated goals? Efficiency: at what cost per unit of outcome — could resources be better used? Equity: who benefits and who bears costs — are effects distributed fairly? Adequacy: even if effective, is the magnitude of change sufficient to solve the problem? Political feasibility is the real constraint on technically good policies.
Formative
Evaluation during implementation — improve as you go
Summative
After program — did it work? Continue or cut?
RCT
Randomized control trial — gold standard for causal evidence

Regulatory Approaches
CASE — Command, Attention to incentives, Self-regulation, Economic instruments
Four approaches to regulation — from direct mandates to market-based tools
Governments can command behavior directly or use prices and incentives to change it indirectly
Command-and-control: set standards and enforce with penalties — most common (Clean Air Act). Economic instruments: taxes on negative externalities (carbon tax), subsidies for positive externalities, tradeable permits (cap-and-trade). Information: require disclosure (nutrition labels, financial disclosures). Deregulation: markets more efficient where failures are minor.

Lowi's Policy Typology
Distributive = everyone gets, Redistributive = take from some give to others
Different policies create different political conflicts and coalitions
Redistributive policies are the most politically contentious because someone visibly loses
Distributive: benefits spread widely, costs diffuse — low conflict, logrolling, pork barrel (farm subsidies, highway spending). Redistributive: take from one group to give to another — high conflict, class politics (welfare, progressive taxation, Medicaid). Regulatory: impose costs on specific groups to benefit public — interest group conflict. Constituent: organize government itself.

Pork barrel — everyone gets something, logrolling
Redistributive

Iron Triangle
CCA — Congress, Client groups, Agency — a closed loop of mutual benefit
Congressional committees, interest groups, and agencies protect each other
Iron triangles explain why inefficient policies persist — three actors mutually protect each other from outsiders
Congressional subcommittee: controls funding and oversight of agency. Interest group: funds campaigns, provides votes and information, lobbies committee. Agency: implements favorable policy, provides jobs via revolving door, provides information to committee. Each protects the others — president and public have difficulty breaking in. Issue networks: looser, more open modern version.
