What is Public Choice Economics (PCE)?

PCE is the application of economic tools (like utility maximization, constrained optimization) to analyze traditional problems of political science.

The Rational Actor Model

The foundation of PCE is the Rational Actor Model (borrowed from the marketplace).

Core Assumption

• Political actors (voters, politicians, bureaucrats): self-interest - maximize personal well-being or utility
• PCE is famously known as “Politics Without Romance” (James M. Buchanan).

Rejection of the Romantic View

• Traditional View: Officials are benevolent “public servants” who aspire solely to the “common good.”
• PCE View: Politicians seek re-election, voters “vote their pocketbooks,” and bureaucrats strive to advance their careers.

The Primacy of Power Seeking: Election and Re-election

A politician’s highest utility function is securing and maintaining office. All behaviors flow from this necessity.

Question

• If we follow the PCE view and officials are really benevolent, does it change their behavior? Will it matter?

• If we follow the traditional view and officials are really self-interested, does it change their behavior? Will it matter?

The Systematic Bias

• Motivation: Winning the next election cycle (2-4 years).
• Result: Short-Term Policy Bias. Politicians favor visible initiatives that yield immediate popularity and campaign donations.
• The Cost: Avoidance of complex, painful long-term solutions (e.g., cutting structural deficits or climate mitigation).

The Influence Game

Politicians act as brokers for powerful external groups.

How Policy is Distorted

1. Need for Funds: Re-election requires continuous campaign funding.
2. Lobbying: Special interest groups (SIGs) offer contributions and incentives to sway legislative decisions.
3. Outcome: Policy is tailored to favor narrow, concentrated interests, often sidelining the broader public good.

The Niskanen Model: Budget Maximization

Public Choice analysis of bureaucracy, pioneered by William Niskanen, identifies the primary motivation of agencies.

Bureaucratic Incentives

• Primary Goal: Budget Maximization.
• Personal Utility: A larger budget equals more administrative discretion, higher prestige, better promotion opportunities, and greater job security.
• Behavior: The “use it or lose it” mentality—spending the entire allocation to justify a larger budget request next year.

The Bureaucrat’s Advantage

Bureaucrats successfully pursue budget maximization by exploiting a key structural imbalance.

Information Asymmetry

• The Bureaucrat: Possesses an information monopoly—detailed, specialized knowledge of the true costs and operations of their programs.
• The Legislator: Is a generalized actor (rationally ignorant of the granular details).
• The Result: Bureaucrats propose “take-it-or-leave-it” budgets, bundling essential services with excessive spending. Politicians fear opposing the core service and approve the inflated budget.

Rational Ignorance

The cost of being informed outweighs the benefit of casting a single, better-informed vote.

The Cost/Benefit Calculus

• Cost: High (hours of time and effort researching complex issues).
• Benefit: Infinitesimally Small (probability of one vote changing the outcome).
• Conclusion: It is economically rational for voters in large elections to remain uninformed and apathetic.

The Free-Rider Dilemma

This concept, central to Mancur Olson’s work, explains why the majority is structurally weak.

Why Organization Fails

• The Problem: If a public good (a beneficial law, a tax cut) is secured, everyone benefits, regardless of whether they contributed time or money to the fight.
• The Behavior: Individuals rationally choose to free-ride, relying on others to do the organizing and lobbying.
• The Vacuum: The lack of organized oversight from the rationally ignorant majority creates a vacuum of accountability, which is efficiently filled by organized special interests.

Concentrated Benefits and Diffused Costs (C/D Dynamic)

This is the primary analytical tool for explaining systemic policy bias. It shows how the political system routinely favors small groups at the expense of the large majority.

Rent-Seeking and Economic Waste

The pursuit of political favor is economically destructive.

Rent-Seeking Defined

• Spending resources (lobbying, contributions) to obtain special privileges (rents) that are created by the political process.
• Example: Lobbying to obtain a tariff that protects high profits.
• PCE Finding: The resources spent on rent-seeking are pure economic waste—wealth is merely redistributed, not created.

Logrolling & Pork Barrel

• Mechanism: Politicians agree to trade votes (logrolling) to assemble a winning coalition.
• Outcome: Funds directed to localized, massively wasteful projects (pork barrel politics). The total social cost often outweighs the limited benefit, but the project is politically popular locally.

Case Study 1: Regulatory Capture (Taxi vs. TNCs)

• The Regulation: Municipal taxi systems restricted licenses (medallions), driving medallion prices up to $1 million (New York).
• Concentrated Benefit: Massive rents for a small number of incumbent medallion holders.
• Diffused Cost: Inflated fares and restricted supply for millions of consumers.
• The Disruption: Uber and Lyft used technology to bypass the captured regulatory structure, serving the broader, previously disorganized consumer interest.

Case Study 2: The Cost of Tariffs

• Concentrated Benefit: Domestic steel and aluminum producers lobby intensely for tariffs (taxes on imports). This allows them to raise prices significantly.
• Diffused Cost: Every consumer and downstream manufacturer (e.g., car companies) pays higher prices. The cost is marginal per person, triggering rational ignorance in the majority.
• The Outcome: The high organizational intensity of the small steel industry consistently wins policy victories over the politically indifferent majority.

Refining the Rational Actor

Empirical evidence challenges the rigidity of the pure self-interest model.

The Modern, Refined Model

• Conditional Cooperators: Individuals willing to contribute to the public good, but only if others are observed cooperating.
• Willing Punishers: Individuals willing to incur a personal cost to punish free-riders, even without direct personal gain.
• Implication: Institutional rules can be designed to foster trust and encourage pro-social behavior.

The Lesson of Constitutional Economics

PCE demonstrates that the problem is not a lack of honest leaders, but flawed incentive structures.

The Focus of Reform

• Ineffective Goal: Fruitless to simply elect “better people.”
• Effective Goal: Constitutional Economics—design better, more effective rules (constitutions, institutions) that constrain self-interest and channel individual maximization toward collective benefit.
• Example: Structural restraints (bicameralism, presidential vetoes) designed to make logrolling more difficult and uncertain.
