A competitive industry includes a large number of identical firms. Each firm has the total cost function TC(q) = q2 + 25. It can be shown that each firm’s marginal cost function is MC(q) = 2q.
a. Derive an equation for a single firm’s supply equation..
b. Derive the individual firm’s average total cost equation. Show your work. Now suppose the market price of the firms’ output is $8.
c. What will each firm’s profit-maximizing output be equal to?
d. What is each firm’s profit equal to at its profit-maximizing output?
consider long run equilibrium
What (if anything) will happen to the number of firms in this industry in the long run? Will it rise, fall, or stay the same? Why? Carefully explain.
f. What will be the equilibrium market price in this market in the long run? Why? Show your work and carefully explain.

A perfectly competitive industry has a large number of potential
entrants. Each firm has an identical cost structure such that
long-run average cost is minimized at an output of 20 units ( q i =
20 ) . The minimum average cost is $10 per unit. Total market
demand is given by Q = D ( P ) = 1 , 500 - 50 P . What is the
industry’s long-run supply schedule? What is the long-run
equilibrium price (...

An industry is perfectly competitive. Each firm is identical and
has a total cost function T C(q) = 50 + 2q^2 . The market demand
function for products is Q = 1,020 − P, where P is the market
price.
(a) Below, graph the firm’s short-run supply curve and provide a
brief explanation.
q*=____ Q*=____ P*=______. N*=______
(b) What is the long-run equilibrium firm quantity (q), market
quantity (Q), price, and number of firms (N)?
q*=____ Q*=____ P*=______. N*=______

Consider a perfectly competitive industry with a large number of
identical firms. Each firm’s long-run average total cost curve
reaches a minimum at $4, where output is 100 units. The current
market price of the good is $4. a. Is this industry in long-run
equilibrium? Why or why not?
b. Suppose that the industry is a constant-cost industry. The
government announces that this product is harmful to consumer
health, so aggregate consumer demand falls (but not to zero!). How
does...
