Consumer and Producer Surplus Flashcards
Consumer Surplus
Difference between market price and what consumers would be willing to pay.
Represents benefit consumers receive when they pay less for something than what they were willing to pay.
Producer Surplus
Difference between market price and price at which producers are willing to sell.
Represents benefit producers receive when selling a product at a higher price than they would have originally sold it for.
Total Surplus
Sum of consumer and producer surplus, measures total benefit to society from production and consumption of a good or service.
Calculate Consumer Surplus
Area beneath demand curve and above price line.
Calculate with formula of area of a triangle B*H/2
Calculate Producer Surplus
Area above the supply curve but below the price line.
Calculate with formula of area of a triangle B*H/2
Market Efficiency
Market efficient when total surplus is maximized.
Occurs at market equilibrium, supply = demand.
Impact of Price Changes on Consumer Surplus
Fall in price increases consumer surplus (vice versa)
Brings new buyers into market, further increasing quantity of consumers and, thus, consumer surplus
Impact of Price Changes on Producer Surplus
Increase in prices increases producer surplus (vice versa)
Brings new sellers into the market
Efficiency vs. Equity in Markets
Efficiency: maximizing total surplus
Equity: fair distribution of resources
Markets tend to priortize efficiency, government is responsible for equity
