A perfectly competitive industry is in long-run equilibrium. Each of the identical firms has a long- run cost function C = 100 + q². As a result, a firm's marginal cost function is MC = 2q. In the long-run competitive equilibrium, (a) How much does the firm produce? (b) What is the equilibrium price? (c) If the market quantity demanded at the equilibrium price is Q = 2500, how many firms are in the market?

In a purely competitive market at its long-run equilibrium, which of the following is not true? a The marginal benefit of the last unit of the product equals the marginal cost of producing that unit. b The maximum willingness of buyers to pay for the last unit of the product equals the minimum acceptable price for the seller of that unit. c Price equals marginal cost, and they are equal to the lowest attainable average cost of production. d The combined amount of consumer and producer surpluses is at its minimum possible.
A perfectly competitive firm sells its good for $20. If marginal cost is four times the quantity produced, how much does the firm produce? Why? Assuming perfect competition, there is not enough information to determine how much the firm is producing. Assuming perfect competition, the firm is producing where MC is twice MR. If the price is $20, then MC is $40. This means that the firm is producing 10 units. Assuming perfect competition, the firm is producing where MR = MC. If the price is $20 and MC is four times the quantity, it is producing 80 units. Assuming perfect competition, the firm is producing where MR = MC = P. Since price is $20, MR is $20. If MC is 4 times the quantity, it is producing 5 units.
Suppose that many small firms operating in the perfectly competitive market set-up. All firms are identical and have the total cost function c (q)= 40+8q+(q^2/10), where q is the individual firm’s production amount. The market inverse demand function is described as P= A - (Q/50), where A>0 is constant, and Q is the market quantity. In the short-run equilibrium, there are 78 firms in the market, and firm’s maximum profit is $22.5 a) find the short-run equilibrium price b) suppose that in the long-run, firms cost function is still the same C (q)= 40+8q+(q^2/10) (assume LR cost function has fixed component of 40) Find the long-run equilibrium number of firms? (Assume market demand in LR = market demand SR)

A market is at the perfectly competitive long run equilibrium, with market price equal to 2. All firms have the cost function TC(q)=5q−6q2+3q3 over the relevant range of output q. Suppose the market demand is 100 units at this price. How many firms are there in the market?

True or false ? why ? 1. In the long run, a perfectly competitive firm with diseconomies of scale is expected to continue increasing its output as firms exiting the market pushing the market price higher, and eventually reaching the long run equilibrium. 2.A perfectly competitive firm should shut down if the price is below the break-even level. 3.The graph on the right shows a perfectly competitive firm with the market price of $30. The firm should stay in the market because the profit is -$60, which is better than the shut-down profit of -$150 (you need to show your work and calculate the two profits).
A firm that behaves in a perfectly competitive fashion has the following cost function: C(Q)=Q² +20 +25. For the current market price, the firm is producing where the total average cost is minimum. What is the market price? Select one: a. 25 b. 5 c. 12 d. 60
Suppose that the market demand for a product is given by ( A > 0 and B > 0). Suppose QABP=-also that in a competitive industry the typical firm’s cost function is given by (k > 2()Cqkaqbq=++0, a > 0 and b > 0).(a) Calculate the long-run equilibrium market price and the output for the typical firm. (b) Calculate the equilibrium number of firms in the market.(c) Describe how changes in the demand parameters A and B affect the equilibrium number of firms in this market. Explain your results intuitively.
A perfectly competitive industry has 150 identical firms. At a price of $8, the typical firm supplies 10 units of output, so the market quantity supplied is nothing units of output. (Enter your response as an integer.)
