Diagnose market failure.
A market fails environmentally when prices do not include important social or ecological costs, so private decisions create excessive harm.
A factory releases pollution without paying for health damage; its product price is too low relative to total cost.
Identify the missing cost, the affected party and the mechanism that could internalise it.
Key idea: Diagnose market failure.
Market failure is not simply a market with an unpopular result.
