Assume declining profits in the market for Internet service force several firms in the
area to drop out of the market. Which of the following best describes the effect of the
reduction in the number of service providers and the subsequent adjustment of the
market to the new equilibrium price and quantity?
A) Quantity supplied would decrease, creating excess supply at the initial equilibrium
price. Demand would then decrease until quantity demanded and quantity supplied are
once again equal.
B) Quantity supplied would decrease, creating excess demand at the initial equilibrium
price. Demand would then decrease until quantity demanded and quantity supplied are
once again equal.
C) Supply would increase, creating excess demand at the initial equilibrium price. Price
would then rise, causing quantity demanded to decrease and quantity supplied to
increase until a new equilibrium is reached.
D) Supply would decrease, creating excess demand at the initial equilibrium price.
Price would then rise, causing quantity demanded to decrease and quantity supplied to
increase until a new equilibrium is reached.
