There is an industry consisting of 12 firms, each with total cost function given by TC(q) 3q²-2q+867, where the fixed costs are non-sunk. The demand for the industry's product given by Q(p) = 448-p per month. Firms are price takers. (a) Find the short-term equilibrium price, demand, the quantity produced by each firm, well as firm's profit. What is the consumer surplus? What about the producer's surplu (b) The government urgently needs to collect some extra tax revenues in the next fo months to meet debt payments. This implies that it needs to collect the amount T = 1000 per month from the industry. Calculate the tax level needed to raise th revenue depending on the type of tax. Which tax type is the better from a welfa perspective? i. An output tax of t per unit sold imposed on the firms.

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 that each firm in a competitive industry has the following costs: Total cost: TC=50 + 1/2q^2 Marginal cost: MC=q where q is an individual firm's quantity produced. The market demand curve for this product is Demand: QD = 120 - P where P is the price and Q is the total quantity of the good. Currently, there are 9 firms in the market. a. What is each firm's fixed cost? What is its variable cost? Give the equation for average total cost.
