Solution
Qs = 9.5 P - 40
P = $ 6.5 per bushel.
(a) Qs = 9.5(6.5) - 40
= 61.75 thousands of bushels.
(b) Now, to calculate elasticity of supply , firstly take the first derivative of Qs with respect to P, we get:
Change in Qs/ Change in P = 9.5.
Elasticity of corn supply = (change in Qs / Change in P ) (P/Qs)
= 9.5 (6.5)/ 21.75
= 61.75/ 21.75 = 2.83 >0 .
It implies that the corn supply is price elastic.
When there is new marketing contract and supply is, Qs = 12P -55
And P = $6.20/ bushel
(c) By putting P in Qs , we get
Qs = 12(6.20) - 55
= 74.4 - 55 = 19.4 thousands of bushels.
(d) Elasticity of supply = (change in Qs/ change in P) (P/Qs)
Change in Qs / Change in P = 12 .
Elasticity = 12 (6.20) / 19.4 = 3.83 >2.83 >0
It implies that the elasticity of corn supply has changed . And now the supply of corn is more elastic.
(e) Total revenue before signing the contract = P(Q) = (6.5)(21.75) = 141.375.
Total revenue after signing the contract = P(Q) = (6.20)(19.4) = 120.28
It implies that the producer is worse off after signing the marketing contract as his producer surplus get reduced.
