1. Market demand for laptop computers is y = 500 - p. But the computers are developed by a hardware firm with a cost function c(y) = 100, & the operating system is developed by a software firm with a cost function of c(y) = 150. a. Calculate the optimal prices for the hardware & software firm to charge, & the total market quantity. (4 points) b. Calculate the optimal price & quantity if it were to behave like a merged firm
a.
Market Demand: y = 500 - p
p = 500 - y
Total Revenue TR = P * y = (500 - y) * y
TR = 500y - y2
MR = d(TR) / dy
MR = 500 - 2y
For Hardware firm:
at equilibrium, MR = MC
500 - 2y = 100
y = 200
p = 500 - 200 = 300
For Software firm:
at equilibrium, MR = MC
500 - 2y = 150
y = 175
p = 500 - 175 = 325
b. When both firms merge, then consider lower MC = 100
So, MR = MC
500 - 2y = 100
y = 200
p = 500 - 200 = 300
