Consumers, Producers and the Efficiency of Markets
producer surplus (equation)
= amount received by sellers - cost to sellers
Consumer surplus is a good measure of buyers' benefits if buyers are rational. (T or F?)
T
Cost to the seller includes the opportunity cost of the seller's time. (T or F?)
T

T

T
consumer surplus
a buyer's willingness to pay minus the amount the buyer actually pays
producer surplus
the amount a seller is paid for a good minus the seller's cost
cost
the value of everything a seller must give up to produce a good
consumer surplus (equation)
= value to buyers - amount paid by buyers
total surplus (equation)
= value to buyers - amount paid by buyers + amount received by sellers - cost to sellers = value to buyers - cost to sellers

T
the efficiency of the equilibrium qty
at qty's less than the equilibrium qty, the value to buyers exceeds the cost to sellers. At qty's greater than the equilibrium qty, the cost to sellers exceeds the value to buyers. Therefore, the market equilibrium maximizes the sum of producer and consumer surplus
willingness to pay
the maximum amount that a buyer will pay for a good
Consumer surplus at price P2
the price falls from P1 to P2, the qty demanded rises form Q1 to Q2, and the consumer surplus rises to the area of the triangle ADF. The increase in consumer surplus (area BCFD) occurs in part because existing consumers now pay less (area BCED) and in part because new customers enter the market at the lower price (area CEF)
efficiency
the property of a resource allocation of maximizing the total surplus received by all members of society
equity
the property of distributing economic prosperity (Wohlstand) fairly among the members of society
Consumer surplus at price P1
the qty demanded is Q1 and consumer surplus equals the area of the triangle ABC
Producer surplus at price P1
the qty demanded is Q1 and producer surplus equals the area of the triangle ABC
welfare economics
the study how the allocation of resources affects economic well-being
Producer surplus at price P2
the supplied rises from Q1 to Q2 and the producer surplus rises to the area of the triangle ADF. The increase in producer surplus (area BCFD) occurs in part because existing producers now receive more (area BCED) and in part because new producers enter the market at the higher price (area CEF)
