1. Production and Costs in Perfect Competition:
b. If the market price for the firm's product is $15 per unit, determine whether the firm should continue production in the short run, and explain why or why not.
2. Characteristics of Perfectly Competitive Markets:
b. How does the entry of new firms into the market affect the price and output decisions of existing firms?
3. Imperfect Competition and Monopoly:
b. Calculate the monopolist’s profit or loss at the profit-maximizing level of output.
c. Discuss the economic inefficiencies associated with monopoly power compared to a perfectly competitive market.
4. Market Structure and Pricing in Monopolistic Competition:
b. Find the quantity that maximizes the firm's profit in the short run, and determine the price it will charge.
c. Explain the long-run equilibrium in a monopolistically competitive market, and discuss how entry and exit of firms affect the firm's profits.
5. Price Discrimination in Imperfect Competition:
b. If the monopolist practices first-degree price discrimination, calculate the monopolist's profit-maximizing price and output for each consumer.
6. Effects of Government Regulation on Imperfect Competition:
b. Discuss whether the price ceiling benefits consumers in the short and long run.
- A perfectly competitive firm faces the following cost structure:
- Fixed Costs (FC) = $50
- Variable Costs (VC) increase from $0 to $100 as output rises from 0 to 10 units.
- Total Costs (TC) = FC + VC.
b. If the market price for the firm's product is $15 per unit, determine whether the firm should continue production in the short run, and explain why or why not.
2. Characteristics of Perfectly Competitive Markets:
- Explain the characteristics of a perfectly competitive market. In your answer, discuss the role of many firms, identical products, price-taking behavior, and freedom of entry and exit.
b. How does the entry of new firms into the market affect the price and output decisions of existing firms?
3. Imperfect Competition and Monopoly:
- A monopolist has the following demand curve: P=100−2QP = 100 - 2QP=100−2Q, where PPP is the price and QQQ is the quantity of output. The monopolist’s total cost function is TC=20+10QTC = 20 + 10QTC=20+10Q.
b. Calculate the monopolist’s profit or loss at the profit-maximizing level of output.
c. Discuss the economic inefficiencies associated with monopoly power compared to a perfectly competitive market.
4. Market Structure and Pricing in Monopolistic Competition:
- A monopolistically competitive firm faces the following demand curve: P=60−2QP = 60 - 2QP=60−2Q, where PPP is the price and QQQ is the quantity. The firm has the total cost function TC=30+10Q+Q2TC = 30 + 10Q + Q^2TC=30+10Q+Q2.
b. Find the quantity that maximizes the firm's profit in the short run, and determine the price it will charge.
c. Explain the long-run equilibrium in a monopolistically competitive market, and discuss how entry and exit of firms affect the firm's profits.
5. Price Discrimination in Imperfect Competition:
- A monopolist has a demand curve P=100−5QP = 100 - 5QP=100−5Q and total cost function TC=40+4QTC = 40 + 4QTC=40+4Q.
b. If the monopolist practices first-degree price discrimination, calculate the monopolist's profit-maximizing price and output for each consumer.
6. Effects of Government Regulation on Imperfect Competition:
- Suppose the government imposes a price ceiling in a monopolistically competitive market. Describe the short-run and long-run effects of this price ceiling on the price, quantity, and firm profits.
b. Discuss whether the price ceiling benefits consumers in the short and long run.
