Deadweight loss

By Christopher Renus
Deadweight loss is lost consumer and producer
surplus that would occur in an efficient market
Deadweight loss is caused by a tax, a price
ceiling, or the pricing from a monopoly.
More elastic supply, the more deadweight loss
Deadweight loss due to that a monopoly
restricts supply below the socially efficient
Lost value to consumers and producers due to
reduction in sales of the good
A monopoly will result in deadweight loss because
A. it creates more total surplus than a perfect competitor.
B. It creates less total surplus than a perfect competitor.
C. It produces a quantity that is allocatively efficient.
D. It produces a quantity that is not productively efficient.
D, Monopolies produce at a lower quantity
5. A deadweight loss is a consequence of a tax on
a good because the tax
a. induces the government to increase its
b. induces buyers to consume less, and sellers to
produce less, of the good.
c. causes a disequilibrium in the market.
d. imposes a loss on buyers that is greater than
the loss to seller
B, The supply curve shifts to the left.
Assume that the original supply and demand curves of a
commodity are S and D, respectively. Also assume that
the government imposes an excise tax (per unit tax)
16. The dead weight efficiency loss created by the tax is
equal to
(A) P,GHPo
(B) P,GKPo
(D) GKl
(E) zero
D, GKI is the area of deadweight loss
1. A. Assume that the market for doodads has an
equilibrium price of $10. At this price suppliers
produce 1,000 units. Draw a supply and demand graph
illustrating the market doodads.
B. Indicate equilibrium price and quantity on your graph.
2. A. The government imposes a maximum price of $12 on
the price of doodads. Explain the effect on the
equilibrium price that this price ceiling will have?
3. A. Now assume that the government imposes a
minimum price of $12 on the price of doodads.
Illustrate this price control on your graph.
B. Determine whether a shortage or surplus is created.
Indicate the quantity of this shortage or surplus.
C. Illustrate the welfare loss that occurs at a price of $12
