Question 13 Perfect competition occurs when none of the individual market participants (buyers & sellers) can influence the price of the product. Under perfect competition marginal revenue (MR) and average revenue (AR) are thus both equal to the market price. The situation in which a firm makes an economic profit is identified as one of the possible short- run positions of a firm under perfect competition. 13.1. Illustrate the given short-run position and explain the situation with reference to your graph.

- Assume that a firm in a perfectly competitive industry has the following total cost schedule: Calculate a marginal cost and an average cost schedule for the firm to complete the following table. Output Total Cost Marginal Cost Average Cost (units) ($) ($) ($) 10 440 15 600 20 720 25 900 30 1,200 35 1,540 40 1,920 If the prevailing market price is $68 per unit, units will be produced. Profits per unit will be and total profits will be . Is the industry in long-run equilibrium at this price? No YesSuppose Glen’s Grinders, LLC is a retail outlet that sells meat grinders for household use and operates in a perfectly competitive market where there is a total of 10 firms in this market including Glen’s Grinders. Basically, all the firms in this competitive market have technologies (production and cost conditions) that are the same as Glen’s. Suppose Glen’s total cost function is given by: C(q) =100 + 25q + q^2 a. Calculate Glen’s optimal output level and profits if the monthly market inverse demand for units of the product is stable and given by: P= 250 - Q b. If Glen is typical of the firms in this industry (same as the other 9), calculate the long-run equilibrium output, price, and profit level that will ultimately prevail in this industry.Consider a perfectly competitive market with similar firms. Assume the total demand in the market is MWTP = 93 - 3Q. Each firm's total cost is TC = q^3 - 2q^2 +4q and its marginal cost is MC = 4 - 4q +3q^2. What is the long-run number of firms in the market? Decimals are possible. Answer to the second decimal place, and do not round until your final answer!
- Suppose that a perfectly competitive firm faces a market price of $12 per unit, and at this price the upward-sloping portion of the firm's marginal cost curve crosses its marginal revenue curve at an output level of 1,800 units. If the firm produces 1,800 units, its average variable costs equal $7.00 per unit, and its average fixed costs equal $1.00 per unit. What is the firm's profit-maximizing (or loss-minimizing) output level? What is the amount of its economic profits (or losses) at this output level?1- Suppose that the total cost function of a firm is given as follows;TC = 500 + 2Q2And the price of the firm’s product is determined by the market equilibrium at $100.a- Set the profit maximizing condition . Find the profit maximizing output level for this firm .b- What is the total revenue ?c- What is the total cost ?d- What is the profit earned by the firm ?e- Illustrate your answer by using a well-labeled graph .f- Denote the break even price level with Pb on the same graph .g- Denote the shut down price level with Ps on the same graph.h- Show the firm’s supply curve on the same graph .i- Does the firm function in short-run or long-run ? Why ?The market determined price in a perfectly competitive industry is P = Rs. 10. Suppose that the total cost equation of an individual firm in the industry is given by the expressionTC 1000+2Q+0.01Q2 At profit maximizing level what is firm total cost, total revenue and marginal cost
- 40) A perfectly competitive firm will earn ________ economic profits in the range of output for which the firm's price is above its minimum average total cost. A) positive B) negative C) zero D) Any of the above answers could be correct. 41) If a perfectly competitive firm's average total cost curve is below its demand schedule at any level of output, then the firm will earn ________ profits. A) positive B) breakeven C) negative D) zero 42) A perfectly competitive firm ________ at the level of output where P = ATC. A) earns an economic profit B) suffers an economic loss C) breaks even D) shuts down 43) If P = MC and MC ATC, then a perfectly competitive firm will earn ________ profits. A) positive B) zero C) negative D) break-even 44) If a perfectly competitive firm is currently producing where P = MC and MC = ATC, then the firm will earn ________ profits. A) positive B) zero C) negative D) above normal 45) If…The market determined price in a perfectly competitive industry is P = Rs. 10. Suppose that the total cost equation of an individual firm in the industry is given by the expressionTC 1000+2Q+0.01Q2 Why does a competitive firm is considered as a price taker and Monopoly firm as a price makerMarginal Analysis II Question 2 Suppose a competitive firm has as its total cost function: TC=18+2q2TC=18+2q2 Suppose the firm's output can be sold (in integer units) at $58 per unit. Using calculus and formulas (don't just build a table in a spreadsheet as in the previous lesson), how many integer units should the firm produce to maximize profit? Please specify your answer as an integer. In the case of equal profit from rounding up and down for a non-integer initial solution quantity, proceed with the higher quantity. Hint 1: The first derivative of the total cost function, which is cumulative, is the marginal cost function, which is incremental. The narrated lecture and formula summary explain how to compute the derivative. Set the marginal cost equal to the marginal revenue (price in this case) to define an equation for the optimal quantity q. Hint 2: When computing the total cost component of total profit for a candidate quantity, use the total cost function provided in the…
- Problem 2: Suppose in a perfectly competitive industry that the market supply and demand forces combine to produce a short-run equilibrium price of$100. Suppose further that a single firm in this industry has a weekly total cost function expressed by the equation: \[ \mathrm{TC}=200+60 q-6 q^{2}+(1 / 3) q^{3} \] (a) Calculate the equations facing the firm: demand, MR, and AR. (b) Calculate the following cost equations of this firm: TFC, TVC, AFC, AVC, MC, and ATC. (c) What is this firm's profit maximizing level of output? What are its profits? (d) At what level of (q) will this firm shut down its operations?please answer question 11 and 12 and 13 11- the market price for the product is $29. If company A wants to maximize its profits and sells in a purely competitive market, how many should they produce? 12- using the price given in Q 11, will company A make an economic profit or economic loss? Show your calculation 13- given the economic profit/loss calculate in Q12, will firms enter or leave this industry or is this industry at long run equilibrium? Why?A firm sells its output in a PCM. The firm’s short-run cost function is given by SC = Q3/300 - 0.2Q2 + 4Q + 10. When the equilibrium market price is 69.5, calculate the level of output and profit that each firm produces in the short-run. With this information, comment on the potential entry/exit of firms in this industry in the long-run.
