Does a competitive firm’s price equal its marginal cost in the short run?
A. If a firm operating in a perfectly competitive market doubles the amount it sells, what happens to the price of its output and its total revenue?
B. How does a competitive firm determine its profit-maximizing level of output? When does a competitive firm decide to temporarily shut down in the short run? Explain, using the concepts of marginal cost, marginal revenue, price, and average variable cost.
Consider the perfectly competitive market for tofu. Many people use tofu as a substitute for meat.
Starting from long-run equilibrium, show graphically what happens in the short and long run to q. Q, P, and in the market for tofu (in comparison to the starting point) if the price of meat is increasing.

What should the firm do? d. Assume the price of the firm’s product in Exhibit 1 is $10 per unit. The maximum profit the firm earns is? Why?arrow_forwardSuppose the shirts industry is perfectly competitive and begins in a long-run equilibrium. (a) Pluto Company invents a new production process that reduces the production cost. What happens to Pluto Company’s profits and the price of shirts in the short run when Pluto Company’s patent prevents other firms from using the new technology? (b) What happens in the long run when the patent expires and other firms are free to use the technology?arrow_forwardWhat is the main feature of a perfect competitive market.

- Assume that apples are produced in a perfectly competitive market. Grande’s Orchard is a typical firm that grows and sells apples. Currently, Grande earns zero economic profit, and the market price of apples is $10 per bushel. (a) Suppose an increase in the popularity of apple cider increases the demand for apples. How will the increase in the demand for apples affect Grande’s economic profit in the short run? Explain. (b) What will happen to Grande’s economic profit in the long run? Explain.arrow_forwardShow the competitive firm in long run equilibrium and describe productive and allocative efficiency. Demonstrate what happens to equilibrium price and quantity with an increase in market demand. Can the firm make economic profit in the short run? What about the long run?arrow_forwardThe graph below shows cost curves for a typical firm operating in a perfectly competitive market. Curve 1 represents Marginal Cost (MC), Curve 2 represents Average Variable Costs (AVC) and Curve 3 represents Average Total Costs (ATC). Suppose that the equilibrium price is $12. What will happen in this market in the long run? a. No new entry/no exit. b.Existing firms will exit. c.New firms will enter.arrow_forward
- The diagram above represents a perfectly competitive firm that faces a demand curve d. Answer the following questions. Show all calculations. From the diagram, how many units should this firm produce to maximize profit? From the diagram data, calculate the firm’s total profit. Assuming no changes in the costs of production, in the long run how much will this firm produce and at what price? From the diagram, at what price will this firm break even? From the diagram, at what price should this firm shut down?arrow_forwardDraw the cost curves for a typical firm. Explain how a competitive firm chooses the level of output that maximizes profit. At that level of output, show on your graph the firm’s total revenue and total cost.arrow_forwardJo sells beautiful flower bouquets at the Sunday markets. Assume the market for flower bouquets is perfectly competitive. Jo sells her bouquets at the market price of $50. At the profit-maximising level of 57 bouquets, Jo's average total cost is $41 per bouquet. The minimum average variable cost is $38 per bouquet. Answer the following questions: a. Jo's economic profit or loss is dollars. (use a negative value if a loss). Answer in b. State whether the following statement is true or false: "At the profit-maximising quantity, Jo is making an economic profit of $9 per bouquet." Type T for true, or F for false c. State whether the following statement is true or false: "Jo should shut down if the market price is $40 per bouquet." Type T for true, or F for falsearrow_forward
- A requirement for a perfectly competitive market is that the sellers sell identical products (consumers don't care who makes the products sold in that market). Think about this from the perspective of the seller. What are the benefits of this? What are the drawbacks? Address these questions in your discussion thread post. You can use a specific product (e.g., bushels of corn) in you discussion if you wish or you can write about generalities.arrow_forwardDescribe how we can identify a competitive firm’s short-run supply curve.arrow_forward(b) In the long-run equilibrium, all firms in a perfectly competitive market earn zero economic profit. Explain why this is true using intuition and graphs.arrow_forward
