Determining Rent in a Market with Low-Cost and High-Cost Firms Suppose firms in a competitive market for house paints have the cost function C(q)=8+2q+2q?. The market is in a long-run equilibrium. (a) What is the price of house paint? (b) Suppose a subset of the firms in the market have developed technology that reduces their costs by 50% at any output level. That means these low-cost firms have the cost function C(q)=4+q+q?. How much additional profit do these low-cost firms earn from the technology? (c) Suppose over time, more and more firms adopt the lower-cost technology. What will be the price of paints in the long run?

Determining Rent in a Market with Low-Cost and High-Cost Firms
Suppose firms in a competitive market for house paints have the cost function C(q)=8+2q+2q?. The
market is in a long-run equilibrium.
(a) What is the price of house paint?
(b) Suppose a subset of the firms in the market have developed technology that reduces their costs
by 50% at any output level. That means these low-cost firms have the cost function
C(q)=4+q+q?. How much additional profit do these low-cost firms earn from the technology?
(c) Suppose over time, more and more firms adopt the lower-cost technology. What will be the
price of paints in the long run?
