Refer to Example 2.5
on the market for wheat. In 1998, the total demand for U.S. wheat was
QD=3,244−283P
and the domestic supply was
QS=1,944+207P.
At the end of 1998, both Brazil and Indonesia opened their wheat markets to U.S. farmers. Suppose that these new markets add
250 million bushels to U.S. wheat demand. What will be the free-market price of wheat and what quantity will be produced and sold by U.S. farmers?
The free-market price of wheat will be $ ___ per bushel.
(Enter your response rounded to two decimal places.)
The free-market price of wheat will be $1.77 per bushel.
what quantity will be produced and sold by U.S. farmers --- 2310.39 million bushels.
calcuation: Equilibrium price and quantity are where Demand =
Supply
3244 - 283P = 1944 + 207P
So, P = $2.65; Q = 3244 - (283 * 2.65) = 2493.18 million
bushels
If 250 million bushels are added to the demand, then
demand = 2743.18 (2493.18+250 = 2743.18)
Then, according to Demand function, 2743.18 = 3244 - 283P
So, P =
1.77.
US producers will produce (supply function): 1944 + (207*1.77) = 2310.39 millin bushels.
