Question 3:
A competitive industry consists of identical 100 producers, all of whom operate with the identical short-run total cost curve TC(Q)=40+2Q2TC(Q)=40+2Q2, where QQ is the annual output of a firm. The market demand curve is QD=300−50PQD=300−50P, where PP is the market price.
What is the each firm's short-run supply curve?
What is the short-run industry supply curve?

Consider a competitive industry comprised of 60 producers, all of whom have an identical short-run total cost curve: SRTC(q)= 64 + 2q^2 where q is the monthly output of a firm and $64 is the monthly fixed cost. Assume that $32 of the firm’s monthly $64 fixed cost can be avoided if the firm produces zero output in a month. The market demand for coal production is D(P) = 400 − 5P, where D(P) is monthly demand at price P...

Assume that the industry for pickles is perfectly competitive. There are 150 producers. 100 of the firms are “high-cost,” with short-run supply curves Qhc = 4P, while the others are “low-cost,” with short-run supply curves Qlc = 6P. Quantities are measured in jars and prices in dollars. A. Derive the short-run industry supply curve for pickles. B. Assume the market demand curve for pickles is given by Qd = 6,000 – 300P. Find the market equilibrium price and quantity. C....

The competitive widget market currently has 3 identical producers with production costs c(q) = 100+10q+q^2, where q is the number of widgets each individual produces. (a) What is each firm’s marginal cost? (b) Find the short run aggregate supply function in this market. (c) If demand for widgets is Qd = 100 − P , what is the long run market price? (d) How many producers are there in the long run equilibrium?

A competitive industry currently consists of 50 identical firms. An individual firm’s total cost function is given by TC = 1⁄2 q2 + 450 and its marginal cost MC = q, where q is the quantity supplied by the firm. Market demand is given by Q = 4000 - 5P, where Q is the market quantity demanded and P is the market price. In the long run market equilibrium, how much will each firm produce?

Suppose in Pakistan, all the firms are identical with identical cost curves which mean industry is perfectly competitive. Now please consider this following information about the industry: A representative firm’s total cost is given by the equation TC = 100 + q2 + q where q is the quantity of output produced by the firm. You also know that the market demand for this product is given by the equation P = 1000 – 2Q where Q is the market...

10.   The widget industry is perfectly competitive. The lowest point on the long-run average cost curve of each of the identical widget producers is K4, and this minimum point occurs at an output of 1,000 widgets per month. When the optimal scale of a firm’s plant is operated to produce 1, 150 widgets per month, the short run   average cost of each firm is K5. The market demand curve for widgets Is. QD   = 150, 000 – 5,000 P Where...

2. In the local cabbage market, there are 5,000 producers that have identical short-run cost functions. They are: where q is the number of bushels produced each period. Out of the fixed cost, 50% is sunk and 50% is non-sunk. The short-run marginal cost function for each producer is: MC(q) = 0.05q. (3*2.5 = 7.5) a) If the local cabbage market is perfectly competitive, what is each cabbage producer's short-run supply curve? Derive the local market supply curve of cabbage....
