Productive efficiency and allocative efficiency are two concepts achieved in the long mm in a perfectly competitive market. These are the two reasons why we call them perfect. How would you use these two concepts to analyze other market structures and label them imperfect?
Firms ill a perfectly competitive market are said to be price takers that is, once the market determines an equilibrium price for the product, firms must accept this price. If you sell a product in a perfectly competitive market, but you are not happy with its price, would you raise the price, even by a cent?
. The market for fertilizer is perfectly competitive. Firms in the market are producing output, but they are currently making economic losses. a) How does the price of fertilizer compare to the average total cost, the average variable cost, and the marginal cost of producing fertilizer?b) Draw a graph, illustrating the present situation for the typical firm that is making losses.c) Assuming there is no change in demand or the firm's cost curves, explain what will happen in the long run to the price of fertilizer, marginal cost, average total cost, the quantity supplied by each firm, and the total quantity supplied to 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.
4. Profit maximization in the cost-curve diagram A Consider a perfectly competitive market for shirts. The following graph shows the daily cost curves of a firm operating in this market. PRICE Dollars per sht 20 HE 16 12 34 LE AD 72 OUTPUT (Theunts of shirts! Chow Ad In the short run, at a market price of $185 per shirt, this firm will choose to produce shirts per day. On the previous graph, use the blue rectangle (dirde symbols) to shade the area representing the firm's economic profit or loss if the market price is $18 and the firm chooses to produce the quantity you already selected. Tool tip: Mouse over the shaded region on the graph to see its area. The area of this rectangle indicates that the firm would have per day. For each price in the following table, calculate the firm's optimal quantity of units produced and determine the economic profit or loss if it produces at that quantity. Use the data from the previous graph to identify its total variable cost. Assume that if the…

1. Consider market adjustment from the short-run to the long-run under a perfectly competitive market. What will happen in the market if a typical firm in the market is making economic profit or loss? 2. Use a set of two graphs, one graph for the market and the other graph for a firm, to show the long-run equilibrium under a perfectly competitive market. What is the level of economic profit for the firms in this case?
