# Lecture 08: Local Public Goods and Fiscal Federalism Source: https://www.youtube.com/watch?v=DIgqgbsg2dw Recap page: https://rapidrecap.app/video/DIgqgbsg2dw Generated: 2026-02-04T20:06:06.676+00:00 --- ## Quick Overview Optimal fiscal federalism, which determines the appropriate level of government for public goods provision, hinges on three main factors: the strength of tax-benefit linkages, the extent of spillovers, and economies of scale, with the Tiebout model suggesting efficient local provision occurs when individuals can 'vote with their feet' to match their preferences, although this efficiency is limited by costly moving, information friction, and financing methods like property taxes. **Key Points:** - Fiscal federalism addresses which level of government should handle specific responsibilities, exemplified by national defense being federal while road fixing is local. - US government spending decentralized significantly between 1927 and 1952 due to World War II defense spending and the New Deal, followed by a shift toward state government responsibility funded by intergovernmental grants like Medicaid between 1952 and 2002. - The Tiebout model posits that efficient public good provision can be achieved locally if people 'vote with their feet' by moving to communities matching their preferences, effectively solving the Samuelson public goods problem by revealing true preferences through mobility. - The Tiebout model faces limitations including costly moving, information friction, the tension between economies of scale requiring larger groups and heterogeneity requiring smaller groups, and reliance on unpopular lump-sum taxes. - Local public goods are typically financed by property taxes, which, when combined with income heterogeneity, incentivize rich communities to implement zoning laws to keep out the poor and avoid free-riding on their higher tax contributions. - The optimal assignment of responsibilities is determined by tax-benefit links (pushing for local provision), spillovers (pushing for central provision), and economies of scale (pushing for central provision); for instance, redistribution is federal due to weak tax-benefit linkages locally. - California's Proposition 13, which severely limited property tax increases, led to an enormous increase in house values (a $1 annual tax reduction increased home value by $7), demonstrating capitalization, but subsequently caused the public school system to decline significantly. **Context:** The lecture continues the discussion on public goods, moving from general theory (Samuelson rule) and cost-benefit analysis to applications in fiscal federalism, which asks what level of government should provide specific services. This topic is highlighted as timely due to unprecedented federal transfers to state governments following COVID-19 relief bills, prompting an examination of historical spending shifts and theoretical models like the Tiebout model to explain optimal responsibility allocation. ## Detailed Analysis The distribution of government responsibilities across federal, state, and local levels, known as fiscal federalism, is largely explained by three factors: tax-benefit linkages, spillovers, and economies of scale. Historically, US government spending centralized significantly in the first half of the 20th century due to WWII and the New Deal, shifting later toward state government roles funded by federal grants like Medicaid. The core theoretical framework for local efficiency is the Tiebout model, which suggests that competition among localities—where citizens 'vote with their feet'—achieves efficient public good provision by making residents self-select into communities matching their preferences, thus overcoming the honesty problem inherent in direct preference aggregation. However, the Tiebout mechanism is imperfect due to costly moving, information asymmetry, and the conflict between economies of scale and preference heterogeneity. Furthermore, the common financing method, property tax (a tax on housing), creates incentives for wealthy residents to exclude poorer residents via zoning laws to prevent free-riding on their higher tax payments. Capitalization—where asset prices embed future tax burdens and benefits—is evident, as shown by Proposition 13 in California, where immediate property tax cuts caused house prices to surge, but ultimately led to a collapse in public school quality because the expected state bailouts did not materialize or the public misjudged the consequences. Ultimately, goods with large spillovers or economies of scale (like defense or redistribution) are better handled federally, while goods with tight local tax-benefit linkages (like roads and police) are suited for local provision, though education remains a potential area where federal involvement should be higher due to national spillovers. ### Historical Spending Trends - US government spending was primarily local in 1902, centralized dramatically between 1927 and 1952 due to WWII and the New Deal - The second half of the 20th century saw a rise in state government activity, often funded by federal intergovernmental grants like Medicaid. ### The Tiebout Model Mechanism - Charles Tiebout proposed that shopping across localities ('voting with your feet') can achieve efficient public good provision, restoring market efficiency absent in centralized public goods provision - In this model, residents move until they reach a town matching their preferences, achieving a Lindahl equilibrium without requiring honest preference revelation. ### Limitations of the Tiebout Model - Competition fails due to costly moving and information friction - A fundamental tension exists between economies of scale (requiring large populations) and preference heterogeneity (requiring smaller, specialized groups). ### Financing and Zoning - Local public goods are typically financed by property taxes, which creates a free-rider problem when incomes vary - Rich residents prefer living with other rich residents to minimize their relative tax burden, leading towns to impose zoning laws to restrict housing supply and keep out the poor. ### Capitalization Evidence - Asset prices, like housing, embed the capitalized value of future tax burdens and public good benefits - California's Proposition 13 demonstrated capitalization, as property tax reductions led to significant house price increases, but this also resulted in the state's public school system severely degrading. ### Optimal Fiscal Federalism Determinants - Optimal provision aligns with strong tax-benefit linkages (favoring local) and significant spillovers or economies of scale (favoring federal) - Redistribution remains federal because local attempts lead to residents leaving to avoid taxation. ### Education as an Anomaly - Education is financed mostly locally and by states, but spillovers (benefits to the whole country from educated workers) suggest a stronger central government role, which is common in other developed nations.
