A decision you can investigate
- A city provides street lighting and sells bus tickets. A private company repairs bicycles.
- Who owns a service and whether it is a public good are different questions.
Build the explanation
- In a mixed economy, prices and private decisions allocate some resources while government ownership, spending and rules allocate others. Public-sector ownership and private-sector ownership differ in control and aims.
- A public good is non-rival and non-excludable: one person’s use does not reduce another’s, and it is difficult to exclude non-payers. Free riders can weaken the private incentive to fund provision.
Work through the evidence
- A pedestrian benefits from an operating street light without paying separately; another pedestrian can benefit at the same time. A bus seat is different: a ticket can exclude non-payers and a full seat cannot serve another passenger simultaneously.
- Privatizing a publicly owned bus company changes ownership, not automatically competition. In fictional economy A, 20 of 100 workers have public-sector jobs; in B, 40 of 100 do. Public employment shares are 20% and 40%, showing different sector importance on that measure.
Which statement separates ownership and public-good status correctly? · Qual afirmação separa corretamente propriedade e status de bem público?
Contractor ownership does not change the light’s consumption characteristics. · A propriedade do empreiteiro não altera as características de consumo da luz.
Test the limits
- Free of charge is not the same as a public good: a free clinic appointment still uses limited staff time. Public provision can finance a public good, even when a private contractor installs it.
- Privatization may improve incentives but can affect fares, access, jobs and public finances. Evaluate regulation and competition rather than assuming ownership alone determines performance.
