Suppose a firm operating in a perfectly competitive industry has costs in the short run given by: SRTC = 8 + ½q2 and therefore MC = q. Assuming that the firm is a price-taker operating in a competitive market, derive an expression for the firm’s supply curve, (the profit maximizing output for the firm as a function of the market price, i.e., q S = f(p). Assuming the firm is one of 100 identical firms in the industry, what is the short-run supply curve for the industry, i.e., Q S = f(p)? If demand is given by Q D = 1000 – 100p, what are the short-run equilibrium price, market quantity, and firm quantity? Is this a long-run equilibrium?

Suppose a firm operating in a perfectly competitive industry has costs in the short run given by: SRTC = 8 + ½q^2 and therefore MC = q. Assuming that the firm is a price-taker operating in a competitive market, derive an expression for the firm’s supply curve, (the profit maximizing output for the firm as a function of the market price, i.e., q^s = f(p). Assuming the firm is one of 100 identical firms in the industry, what is the short-run supply curve for the industry, i.e., Q^s = f(p)? If demand is given by Q^D = 1000 – 100p, what are the short-run equilibrium price, market quantity, and firm quantity? Is this a long-run equilibrium?

Consider a perfectly competitive firm with a short-run total cost function given by TC = q2 + 100 where q is the level of output. The short-run marginal cost function is given by MC = 2q If the price of output is $60, how much output should the firm produce in order to maximize profit? Calculate the firm’s economic profit at this level of output Assuming that each firm in the industry has an identical cost function, is $60 a long-run equilibrium price for this perfectly competitive industry?
Assume that a competitive firm has the total cost function: TC=1q3−40q2+820q+1900 T C = 1 q 3 - 40 q 2 + 820 q + 1900 Suppose the price of the firm's output (sold in integer units) is $600 per unit. How many units should the firm produce to maximize profit? What is the total profit at the optimal output level? Please specify your answers as integers.
Consider a competitive industry with a market demand curve of P = 120 - Q, where P is market price and Q is the quantity demanded in the market. In the short run there are 4 firms in the industry, and each firm has a total cost function of TC = 144 + q^2, where q is output of the individual firm. The short-run industry supply curve Qs is?
Multiplying one firm’s short-run supply function to the number of firms in a specified industry will give you the short-run market supply function. True or false.
Suppose the cost function for a firm is given by C(Q) = 100 + Q2. If the firm sells output in a perfectly competitive market and other firms in the industry sell output at a price of $10,A) What level of output should the firm produce to maximize profits or minimize losses?B) What are the profits at the optimal output amount? C) Should the company produce this optimal amount or should it shut down?
Assume the market for chips is perfectly competitive. The market supply and demand curves for chips are given as follows: supply curve: P = 0.000002Q demand curve: P = 11 - 0.00002Q The short run marginal cost curve for a typical chips factory is: MC = 0.1 + 0.0009Q Determine the equilibrium price for chips. Determine the profit maximizing short run equilibrium level of output for a chips factory. Assuming that all of the chips factories are identical, how many chips factories are producing chips?
Consider a perfectly-competitive industry where each firm has the following long run cost function C(q) = q3 − 12q2 + 105q, where q is the firm’s output. What is the long-run equilibrium price in this market? (Round your final answer to two decimal places, if necessary.)
Consider a competitive constant-cost industry in which each firm's marginal and average costs are given by the formulas MC = 4q and AC = 2q + 50/q, where q represents the quantity supplied by the firm. i) Determine the quantity supplied by each firm in long-run equilibrium, and determine the firms' break-even price.
Assume that a competitive firm has the total cost function: TC=1q3−40q2+880q+2000 T C = 1 q 3 - 40 q 2 + 880 q + 2000 Suppose the price of the firm's output (sold in integer units) is $550 per unit. Create tables (but do not use calculus) with columns representing cost, revenue, and profit to find a solution. How many units should the firm produce to maximize profit? Please specify your answer as an integer. What is the total profit at the optimal output level? Please specify your answer as an integer.
Consider a firm in a perfectly competitive market. The firm’s marginal cost, average cost and average variable costs are given by the figure below. Suppose that the current market price is p=10. In order to maximize its profit, the firm will produce q = ___________ units of output.
Consider a firm that operates in a market that competes aggressively in prices. Due to the high fixed cost of obtaining the technology associated with entering this market, only a limited number of other firms exist. Furthermore, over 70 percent of the products sold in this market are protected by patents for the next eight years. Does this industry conform to an economist’s definition of a perfectly competitive market?
