Public Goods & The Free-Rider Problem

non-rivalrous: one person's use doesn't reduce another's
non-excludable: can't prevent use by non-payers
markets under-provide → role for government

Figure 12.3 — under-provision at market equilibrium

wk6 l2 — public goods — slide 7

Public goods

Two conditions that break the invisible hand:

non-rivalrous — my use doesn't subtract from yours
non-excludable — I can't stop non-payers

why does the free-rider problem lead to under-provision?

each consumer reasons "someone else will pay," so willingness-to-pay is understated at the market level. aggregate demand D_market sits below true social demand D_social → equilibrium quantity < socially efficient level.

why does the free-rider problem lead to under-provision?

each consumer reasons "someone else will pay," so willingness-to-pay is understated at the market level. aggregate demand D_market sits below true social demand D_social — at any price the market quantity falls short of the socially efficient one.
