What is the adjustment process from short-run abnormal profit to long-run equilibrium in a perfectly competitive market? c) Please find below Pricing options for firm A and B, along with individual payoffs (Firm A's payoff/Firm B's payoff) Firm A Price £2 Price £1 Assume you are the pricing manager at Firm A; i) ii) Price £2 £10,000/£10,000 £12,000/£5,000 Firm B Price £1 £5,000/£12,000 £6,000/£6,000 What is your payoff for a 'maximin' strategy? What is your payoff for a 'maximax' strategy? Does a dominant strategy exist within this prisoners' dilemma?

Problem #1: Assume that the following marginal costs exist in catfish production: 17 Quantity Produced (units per day) Marginal Cost (per unit) 10 11 12 13 14 15 16 $4 6 8 10 12 14 16 18 (a) Graph the MC curve. (b) Use the data on market demand below and graph the demand and MR curves on the same graph. Quantity demanded (units per day) 10 Price (per unit) 11 12 13 14 15 16 17 $25 24 23 22 21 20 19 18 (c) At what rate of output is MR = MC?

Question 4: Profit Maximization Price per Quantity Marginal Use the table on the left to answer the following sub-questions. (Hint: It may be useful to draw a diagram based on the information provided to Unit Demanded Revenue $100 $90 40 $90 help you visualize the question.) $80 80 $70 Imagine that a vaccine for COVID-19 is designed, patented and produced by PharmaCo, Inc.; so, now PharmaCo, Inc. is a monopolist producer of this new vaccine that everyone needs. Phar- maCo, Inc. has a constant marginal cost of pro- duction of $10 per unit of the vaccine. For sim- plicity, we will say that average total cost is also constant at $10 per unit. $70 120 $50 $60 160 $30 $50 200 $10 $40 240 -$10 $30 280 -$30 $20 320 -$50 $10 360 -$70 1. How many units of the vaccine will PharmaCo, Inc. produce and supply? Why? 2. How much profit is earned by Pharmaco, Inc. if it produces the quantity you mentioned above? 3. If Pharmaco, Inc. did not have a patent, and the market were perfectly competitive with…

Marginal cost= 2x+3 Average variable cost= x+3 Variable cost=x^2 + 3x x is the daily output. Product's price is 13 dollars. Part a) Calculate the level of output that will be produced.  Part b) Calculate the producer surplus of the firm.  Part c) The fixed costs are 5 dollars. In the short run, is the firm making a 0 economic profit, a positive profit, or a negative profit? Explain why.
