Assume that no matter how many firms operate in the induatry, every firm is identical and faces the same marpinal cost (MC), averapt total cost (ATC), and average variable cost (AVC ) curves plotted in the following praph. The following graph plots the market demand curve for thodium. If there were 10 firms in this market, the short-run equilibrium price of rhodium would be per pound. At that price, firms in this industry would. Therefore, in the long run, firms would the rhodium market. Because you know that competitive firms earn economic profit in the long run, you know the long-run equilibrium price must be per pound. From the graph, you can see that this means there will be firms operating in the rhodium industry in long-run equilibrium. True or False: Assuming implicit costs are positive, each of the firms operating in this industry in the long run earns positive accounting profit. True FalseSuppose we have two identical fırms A and B, selling identical products. They are the only firms in the market and compete by choosing quantities at the same time. The Market demand curve is given by P=287-Q. The only cost is a constant marginal cost of $13. If Firm A produces a quantity of 60 and Firm B produces a quantity of 33, what is market price? Enter a number only, no $ sign. 194
- Two farmers produce milk for local town with local milk demand given by Q=100-1/3P (P denotes price measured in Rands, Q denotes the quantity measured in litres). Both farmers have the same cost function given by TC=150+2q (where q denotes output)a. What output should farmer 1 produce if he or she expects their rival to produce 20 units?WEBCAM RECORDING Industrial Economics da 6 A market is characterised by an inverse demand curve p =8 – 2Q where Q is total quantity.

If more than one firm choose the same price the demand is divided equally among them. There are no other firms in the market. Two firms have the same constant marginal cost cL and the third one has a higher marginal cost cH : cL < cH . Explain what will be the equilibrium price in this market.
- There are 80 firms of type A and 60 firms of type B in a perfectly competitive market. On one hand, type A firm faces a fixed cost (all sunk) of $12 and average variable cost is 2q. On the other hand type B firm faces a fixed cost (all sunk) of $100 and the variable cost is 3g. Market demand function is given by Q=1200-70P Find the equilibrium quantity of a type A firm and its profit, respectively. Oq=4, profit-$4 Oq=2, profit=$4 q-3, profit=$6 q=5, profit-$233. Suppose there are only two firms in an industry selling an identical product where the quantity produced must be set well in advance of the good being sold in the market (and thus the quantity cannot be changed rapidly). The market demand for this good is given by the following equation: Q = 1,000 - 4P. Firm A's marginal cost of production is as follows: MC Α = 30 + 1.5Q₁. Firm B's marginal cost of production is as follows: MCB 100+ 2.5QB. Assume that each firm knows the other's cost of production. = a. If the two firm's decide their output simultaneously, how much output will each firm produce? What price will be charged in the market for the good? b. If the firm A's decides its output first and then B decides its output second, how much output will each firm produce? What price will be charged in the market for the good? Does A have an advantage by setting output first? Explain.Each of 1,000 identical firms in the competitive peanut butter industry has a short-run marginal cost curve given by SMC = 5 + Q. If the demand curve for this industry is 20 P = 14 – 1,000 what will be the short-run loss in producer and consumer surplus if an outbreak of aflatoxin suddenly makes it impossible to produce any peanut butter? Instructions: Round your answers to the nearest whole number. Producer surplus: $ Consumer surplus: $
- There are two firms in the pumpkin industry: C and S. The demand function for pumpkins is q = 3, 200 - 1, 600p. The total number of pumpkins sold at the market is q = qC + qS, where qC is the number that C firm sells and qS is the number that S firm sells. The cost of producing pumpkins for either firm is $0.50 per pumpkin no matter how many pumpkins they produces. 1. Every spring, each of the firms decides how many pumpkins to grow. They both know thelocal demand function and they each know how many pumpkins were sold by the other firmlast year. In fact, each firm assumes that the other firm will sell the same number this year asits sold last year. So, for example, if firm S sold 400 pumpkins last year, firm C believes thatfirm S will sell 400 pumpkins again this year. If firm S sold 400 pumpkins last year, what doesfirm C think the price of pumpkins will be if firm C sells 1,200 pumpkins this year? 2. If firm S sold 400 pumpkins last year, firm C believes that if he sells qtCpumpkins…Use the following to answer questions (1) - (14): Suppose the local market for flat glass, considered a homogeneous product, consists of two firms, A and B.
