At its current level of production a profit-maximizing firm in a competitive market receives $15 for each unit it produces, and faces an average cost of $10. At the market price of $15, the firm’s marginal cost curve crosses the marginal revenue curve at an output level of 1,000 units. A. Draw a diagram that depicts the typical firm in this market. B. What is the firm’s current profit? C. What changes are likely to occur in this market and why?

1) The cost curves for a firm in a perfectly competitive industry are given below. Complete the table. If the firm operates in a perfectly competitive market, and the market price is $25 per unit, what Quantity should this firm produce at?

"A profit maximizing firm seeks to produce at an output where its marginal revenue is equal to its marginal costs." Agree or disagree with this statement.

a.Suppose a perfectly competitive firm can produce10000 bushels of corn a year at an output at which marginal revenue is equal to marginal cost. The market price of corn per bushel is $2. The firm's total costs per year are $30000 and fixed costs per year are $15000. Show and explain which of the following is true: In the short run, this firm should a) Produce 20000 bushels to try to increase economic profit. b) Produce 10000 bushels of corn because, although they are losing money, they are losing less than if they shut down. c)Shut down. d) Continue producing until the price of corn increases.       b.A perfectly competitive firm, with MC=q operates in a market character,zed by the following market demand and supply conditions: Demand: Q=20000-100P Supply: Q=100P   How much output does this competitive firm produce to maximize profit?
