The Nature of Public Goods
A public good exhibits two defining characteristics: it is non-rivalrous (one person’s use does not diminish another’s) and non-excludable (no one can be effectively barred from using it). Classic examples include national defense, which protects all citizens equally, and street lighting, which illuminates roads without limiting access. Private firms struggle to profit from non-excludable goods, so governments step in to ensure they’re supplied at socially optimal levels. When markets alone provide these goods, free-riding (benefiting without paying) leads to chronic under-provision. Recognizing these features explains why certain services reside in the public sector and how societies decide what to supply collectively.
Types and Examples of Government Services
Governments also deliver services that blend public-good and private-good elements. Consider: By examining each service’s mix of non-rivalry and excludability, policymakers tailor funding and access rules. This strikes a balance between efficiency (getting the right amount) and equity (sharing costs fairly).
Provision Mechanisms: Direct Supply vs. Vouchers
Governments can supply services through: Direct supply, where agencies own assets and employ staff (e.g., border patrol, traffic control). Voucher/subsidy models, in which public funds follow the user to private providers (e.g., school or health-care vouchers). Vouchers introduce consumer choice and competition, potentially improving quality and containing costs, but require robust oversight to prevent cream-skimming and to guarantee universal access.

Why this matters
A streetlight doesn't stop working just because the person under it didn't pay. Something non-rivalrous and non-excludable, like street lighting or national defense, can't be sold like a sandwich, because there's no way to keep a non-payer from benefiting anyway.
City Z's Green Heart initiative solved the free-rider problem in practice: property taxes covered the base cost, concession fees added revenue, and vouchers kept the park open to families who couldn't afford user fees. That blend makes the trade-offs concrete instead of theoretical.
From one teacher to another
I use this reading to help students understand why some goods and services are government's job rather than the market's. My students learn the concept of non-rivalrous and non-excludable goods, using examples like national defense and street lighting to see why private firms cannot profit from providing them. The City Z case study shows how a city combined property taxes, concession fees, and targeted vouchers to finance a public park, addressing the free-rider problem while ensuring access for low-income families. They explore different financing approaches (direct supply, vouchers, and public-private partnerships), recognizing that different goods require different solutions. This helps them see the reasoning behind government involvement in parks, schools, defense, and infrastructure.

Student Worksheet
City Z converted 200 acres of derelict land into a new park in 2018, paying for upkeep through property tax increases and concession fees charged to food stalls and bike rentals inside it. A voucher program gave seniors and low-income families $100 toward guided fitness classes, keeping access open despite the added fees. By 2021 visitor counts had risen 40 percent and nearby asthma hospitalizations had fallen 15 percent.
