Question
Could I have help understanding how to solve an equation like this?
Continuing with the equations:
P = 80 – 3Q
MC = 20 + 13Q
Note:
MR = 80 – 4/3Q = 80 – ½Q – 2½Q = P – 3Q = P- (dP/dQ)Q = P(1 – 1/ED)
Setting MC = MR yields the profit-maximizing markup over marginal cost:
MC =
P(1 – 1/ED)
= MC[1/(1 – 1/Eo)]
(P – MC)/P :
1/ED
%3D
a. Assume the market is monopolized. Find Q*, P*, and the elasticity of demand Ep at the profit-
maximizing point and verify that the markup equation is satisfied:
Q* =
P* =
ED =
(P- MC)/P =
b. Assume the market is monopsonized. Using the procedure in (a), which found MR as a function of
P and ED, find a formula for marginal expenditure (ME) as a function of P and Es.
ME =
