Lerner 1972
Basic Idea
Consumer sovereignty: everyone gets their preferences met without extra sacrifice from others.
Objections and Considerations
Focus on fulfilling wants, regardless of origin.
Aligns with democracy and efficient resource use.
"Ideal output": achieving consumer sovereignty.
Market Mechanism
Free markets need enforced laws and habits to establish property rights for buying/selling.
Rights originate from conflicts, resolved through economic transactions.
Imperfections and Corrections
Consumer sovereignty hindered by:
Imperfect competition
Suppressed knowledge
Ignorance and fraud
Corrections require changing/enforcing laws.
Denigration of Consumer Sovereignty
Deviations from marginal costs (political, sentimental reasons) reduce consumer sovereignty.
Critics argue consumers are manipulated by advertising.
Price approximates marginal cost; without restrictions, price equals average cost.
Inequality of Income
Market may prioritize rich over poor, but marginalism isn't to blame for income inequality.
Paying factors based on marginal productivity aims for consumer sovereignty, not justice.
Public Goods
Market mechanism inapplicable because everyone benefits, so no one pays.
Privatization necessary for efficient production.
Ecology
Awareness of Earth's finite nature.
Developing charges for environmental damage turns public goods into private goods.
State of Plenty
Marginal economic mechanisms unnecessary when everyone has enough.
Market mechanism might still be needed to indicate what to produce.
