3. Consider the perfectly competitive markets for bottled water in two cities, A and B. Bothhave a downward-sloping demand curve and upward-sloping supply curve, and each marketis currently in long run equilibrium at the same price. The demand curves are similar, butin city A the supply curve is more price elastic than in city B.a) There's a shock: an accident causes the tap water in the area to become undrinkable.In two diagrams, one for each city, compare the effect on price and quantity traded inthe two cities, assuming that a new equilibrium is reached. Explain your diagrams.b) Following on from your answer to a), explain what would happen in the model to thenumber of suppliers and their profitability, in each of the short run and the long run.

Which of the following offers the best explanation of why “marginal revenue equals marginal cost” is the rule that indicates the profit-maximizing output level? a. If output were reduced from the profit-maximizing level, then the firm would be gaining marginal revenue that exceeds marginal cost, and thus increasing the level of profit. b. The marginal revenue is equal to the marginal cost at all levels of output for a perfectly competitive firm. c. If output were increased from the profit-maximizing level, then the firm would be gaining marginal revenue that is less than the marginal cost incurred in producing this additional unit, and thus reducing the level of profit. d. Because the firm colludes with other similar firms to set price equal to marginal cost.

6. Deriving the short-run supply curve The following graph plots the marginal cost (MC) curve, average total cost (ATC) curve, and average variable cost (AVC) curve for a firm operating in the competitive market for sun lamps. 100 90 80 70 60 50 ATC 40 30 20 10 0 0 5 AVC MOD 10 15 20 25 30 35 40 45 50 QUANTITY (Thousands of lamps) For every price level given in the following table, use the graph to determine the profit-maximizing quantity of lamps for the firm. Further, select whether the firm will choose to produce, shut down, or be indifferent between the two in the short run. (Assume that when price exactly equals average variable cost, the firm is indifferent between producing zero lamps and the profit-maximizing quantity of lamps.) Lastly, determine whether the firm will earn a profit, incur a loss, or break even at each price. Price (Dollars per lamp) 10 20 32 40 50 60 Quantity (Lamps) Produce or Shut Down? Profit or Loss?

Assume that Vartoli Saadettin decides to start up a peddler's trade. His bench is in a perfectly competitive market and has the following long-run total cost function: LRTC(q) = 80q – 8q² + q³ Vartoli Saadettin also observes that market demand is given by: Q=12500-50P. Note that Q represents the market quantity, including all the other firms in the market.

1. Assume you have a perfectly competitive market with two types of firms. The only difference between the two types of firms is that the minimum average cost at which firms of type A can produce is lower than the minimum average cost at which firms of type B can produce. a. Give a graphical example of what the individual long run supply functions of a type A firm and a type B firm may look like. Explain the shape in detail. b. Based on your example, what will the aggregate supply curve of a market with 2 firms, one type A and one type B, look like? Explain the shape in detail. C. Assume now that all potential firms are identical. Evaluate the impact of a demand shock on the long run equilibrium market price and firm numbers. You must use graphical analysis and explain in detail.
