Question
In western Kansas, corn can be grown in two
ways with or without irrigation. Dryland
farmers, who do not irrigate their corn, have
long-run average costs of
LAČC=Q^2-20Q+105 and long-run marginal
costs of LMCd=3Q^2-40Q+105, where Q is
measured in thousands of bushels. Farmers
lucky enough to water rights or river access
have lower costs: Their long-run average cost
is LACT=Q^2-16Q+67 and their long-run
marginal costs are LMCT=3Q^2-32Q+67.
A) If the corn market is in long-run
equilibrium,with both dryland and irrigated
corn being grown, what must the price of
corn be?
B) How much economic rent will farmers with
access to irrigation earn?
C) Explain why irrigating farmers earn
economic rents, but will still earn zero
economic profits.
