Questions using nonexcludable
Problem 1
Is every government-provided service nonrival and nonexcludable?
Answer and explanation
No. Some have limited places, congestion, or eligibility restrictions. Public provision and the technical public-good category answer different questions. Classify the use and exclusion conditions rather than the payer alone.
