Ch7. State and Local Finance — Fiscal Federalism in the United States

Core Questions of Fiscal Federalism

Fiscal federalism addresses how revenue-raising authority and spending responsibilities should be divided among levels of government.

Core questions in the US context:

Which functions belong to the federal government vs. states vs. local governments?
How should tax bases be assigned across levels?
How should fiscal disparities between jurisdictions be addressed?

Oates’ Decentralization Theorem

Wallace Oates argued: If the preferences of residents differ across jurisdictions, decentralized provision of public services by state and local governments is more efficient than uniform central provision.

Reasoning: Lower levels of government have better information about local preferences and can tailor services accordingly.

Limits: Functions with spillovers across jurisdictions, significant economies of scale, and income redistribution should remain at the federal level.

Functional Assignment in the US

Function	Level	Rationale
National defense, foreign policy, monetary policy	Federal	National public good; scale economies
Income redistribution (Social Security, Medicare)	Federal	Prevents “race to the bottom” in state redistribution
Macroeconomic stabilization	Federal	State fiscal policy spills over to neighboring states
K–12 education, police, fire	State/Local	Preferences vary by community; experimentation beneficial
Infrastructure (highways, transit)	Shared	External benefits justify federal involvement (Highway Trust Fund)

Designing State and Local Taxes

An ideal state/local tax satisfies these criteria:

Benefit principle fit: Taxpayers receive services roughly commensurate with what they pay
Low mobility: Taxed base cannot easily move to avoid the tax
Low inter-jurisdictional spillovers: Burden should not be exported to other states
No need for macroeconomic stabilization: Redistribution and stabilization are federal functions

Ideal state/local taxes: Property tax, land value tax, local user fees (water, transit fares) Poor fits for state/local level: Corporate income tax (capital is mobile), personal income tax (redistribution role)

US state/local tax mix:

Property taxes (primary local revenue): fund K–12 education and local services
State sales taxes: 45 states + DC
State income taxes: 41 states
State/local own-source revenue: roughly 40% of total state/local spending

Federal Grants-in-Aid

The federal government transfers funds to states and localities through two main mechanisms.

Purpose: Address vertical fiscal imbalance (federal tax capacity > federal spending responsibility for many services) and horizontal fiscal disparities (rich vs. poor states).

Block Grants (General-Purpose Grants)

Fixed-dollar federal transfers that states may use broadly within a program area.

Example: Community Development Block Grants (CDBG), Social Services Block Grant
High state discretion
Effect: parallel shift of state budget constraint (income effect only)

Categorical Grants (Conditional/Matching Grants)

Federal funds restricted to specific uses.

Type	Mechanism	Effect
Project grants	Competitive application	Targets specific programs
Formula grants	Allocated by formula (population, poverty rate)	Medicaid, Title I education
Matching grants	Federal matches state/local spending	Lowers the effective price → price effect + income effect

Economic effect of a matching grant:

Reduces the state’s effective cost of providing the matched service
Generates both a price effect (more of the service provided) and an income effect
States provide more of the matched service than with an equivalent block grant

Block grant vs. categorical grant comparison:

	Block grant	Categorical / Matching grant
Use restriction	Broad program area	Specific purpose
State autonomy	High	Low
Fiscal equalization	Yes	Targeted service expansion
Efficiency	Reflects local preferences	Good for services with positive spillovers

Fiscal Equalization

Horizontal Fiscal Imbalance

Fiscal capacity varies enormously across states and localities:

High-revenue states (New York, California, Connecticut) vs. low-revenue states (Mississippi, West Virginia)
Urban property-rich school districts vs. rural property-poor districts

Federal remedies:

Formula-driven grants weighted toward lower-capacity states (Medicaid FMAP formula)
Title I education grants targeted to high-poverty districts
Revenue sharing proposals (less common today)

Vertical Fiscal Imbalance

State/local spending responsibilities exceed state/local taxing capacity.

States depend on federal grants for roughly 30–35% of their revenue.

Problem: Decision-making unit (state) is separated from revenue-raising unit (federal) → reduced fiscal accountability.

Reform direction: Expand state tax authority and state spending discretion simultaneously.

Tiebout Hypothesis: US Applications

Tiebout hypothesis (reviewed from Ch3): Households reveal preferences by moving to jurisdictions offering their preferred public service-tax package.

US Evidence

School district choice:

School quality is capitalized into housing prices — households pay a premium for access to better-funded districts
This concentrates affluent households in high-spending districts and concentrates poverty in low-spending districts

Issues:

Only wealthy households can effectively “vote with their feet”
Fiscal sorting → reinforces inequality in educational opportunity
School finance equalization lawsuits (e.g., Serrano v. Priest in CA; Abbott districts in NJ)

Municipal Finance and Fiscal Stress

Municipal bonds (munis):

Tax-exempt interest income at the federal level (and typically the issuing state)
Lower nominal interest rate than taxable bonds
Funds capital projects: schools, water systems, roads

Municipal fiscal stress:

Detroit bankruptcy (2013): pension obligations and declining tax base
Puerto Rico debt crisis: ongoing (PROMESA oversight board)
“Soft budget constraint”: expectation of federal/state bailout → moral hazard in borrowing

Soft budget constraint: When subnational governments expect a bailout in fiscal distress → incentive to borrow and spend excessively.

Solutions:

Credible no-bailout commitment by higher levels of government
Statutory debt limits on municipalities
Chapter 9 bankruptcy process as a disciplining mechanism

Frequently Tested Concepts

Oates’ decentralization theorem: Diverse local preferences → decentralized provision is more efficient than uniform central provision

Ideal local taxes: Property tax, land value tax (immobile base, benefit principle fit)

Block grant vs. matching grant: Block grant = income effect only. Matching grant = price effect + income effect → more of the targeted service provided.

Tiebout: “Voting with your feet” — works well when households are mobile and jurisdictions are numerous
