What is the long-run equilibrium number of firms in this industry? What is the quantity produced by each firm in this long-run equilibrium? Question 2 (Short-Run vs. Long-Run: Conceptual Question) Each worker (L) costs $10 to hire, each unit of capital (K) costs $10 to rent. The following table denotes the combinations of capital and worker mixes for a representative firm to produce certain quantities of good: L K TC AC 100 20 20 400 200 60 20 800 200 30 30 600 1. What should a firm do in the short-run if it wishes to increase the production from 100 units to 200 units? Why? 2. What should a firm do in the long-run if it wishes to increase the production from 100 units to 200 units? Why? Relate the difference between short-run and long-run average cost curves in light of answers in part 1 and 2. 4. Can you tell if the firm is experiencing increasing, decreasing or constant returns to scale? Business Learning Center - Econ 101 (Hansen) - Session 11 (October 28, 2015) Tutor: Kanit Kuevibulvanich Question 3 (Long-Run Average Cost Curves and Profit Maximization) COST INDUSTRY REPRESENTATIVE FIRM MC1 ACI LRAC MC2 AC2 15 12 400 600 20 40 50 Each firm has the ability to choose Scale 1 or Scale 2, denoted by MC1, AC1 and MC2, AC2, respectively. Consider the industry demand-supply curve and the cost structure of a representative firm and answer the following questions: 1. Suppose the current market price is $15, then each firm would produce units, and there are firms in the industry. Each firm earns an economic profit of . What would happen in the long-run? 3. How many firms are there in the long-run?Exercises Question 1 (Numerical examples) In this industry, all firms operate using the same production function. All firms hire workers in the perfectly competitive labor market and sell goods in the perfectly competitive goods market. Suppose a representative firm has the production function exhibited in the following table: Quantity of Total Labor (L) Product (Q) 0 1 40 2 70 3 90 4 105 5 115 6 120 Suppose the current wage is $100 per worker and the price of goods is $10 per unit. How many workers should each firm hire? 2. Suppose there are less people willing to work, causing the wage to increase to $200, and as a result, each firm is now hiring 4 workers, what must have happened to the price of goods for such equilibrium? 3. Instead, suppose better technology doubles the output produced by any firms, it is expected that the demand for labor would [ increase / decrease ], causing the wage in the labor market to [ increase / decrease ]. Question 2 (Two factors of production) You are the owner of a manufacturing company using capital and labor to produce goods. Currently you are hiring 200 workers and renting 100 machines. Through competitive factor markets, the wage (price of labor) is $20 per worker and the rent (price of capital) is $10. The 200th worker brings 40 units of output to the production, while the 100th machine brings 30 units of output to the production. This good sells for $20 per unit in the perfectly competitive market. 1. State the optimal rules for the choice between hiring labor and renting capital. (Hint: Recall the bang-for-the-bucks) 2. Is the current levels of labor and capital the most profitable? If not, should you hire or fire workers? Should you rent more or less capital? Question 3 (Factors complementarity and substitutability) A car manufacturer uses assembly robots, which are complementary with robot technicians and substitutable with hand-made workers. An increase adoption of assembly robots used will: [ increase / decrease ] demands for robot technicians. [ increase / decrease ] demands for hand-made workers. In the aspects of marginal products, this increased adoption of assembly robots used will: [ increase / decrease ] marginal products of assembly robots. [ increase / decrease ] marginal products of robot technicians.Question 8 (Producer Theory) 1. Consider the following information table regarding costs of production. Quantity Fixed Cost ($) | Variable Cost ($) 12 0 24 32 48 68 15 108 6 168 a. If the market price is $40, this firm should produce units to maximize its profits, which is Business Learning Center - Econ 101 (Hansen) - Handout 20 (December 14, 2015) Tutor: Kanit Kuevibulvanich b. If the market price is $20, this firm should produce units to maximize its profits, which is c. If the market price is $16, this firm should produce units to maximize its profits, which is. d. If the market price is $8, this firm should produce units to maximize its profits, which is 2. Suppose a firm uses ten variable inputs. As this firm increases the quantity produced using twice as much of all variable inputs, the average total cost increases. Given this information, this firm is experiencing [ increasing marginal returns / diminishing marginal returns / increasing returns to scale / decreasing returns to scale ]. Problem 9 (Producer Theory - Perfectly Competitive Market) 1. Suppose the market for bicycle is perfectly competitive. Each identical firm has cost functions in producing q bicycles described by the following equations Total cost function: TC =5q2 + 2q + 125 Marginal cost function: MC = 10q + 2 Let P and Q be the market dollar price per unit and market quantity of bicycles, the market demand function for bicycles is given by the following equation Market demand: P = 82 - Q There are initially 10 firms in the market. a. What are the equilibrium market price and equilibrium market quantity of bicycles in the short run? b. What are the equilibrium market price and equilibrium market quantity of bicycles in the long run? C. Since there are initially 10 firms in the market, how many firms will enter or exit from this industry in the long run? 2. Assume that all firms - incumbent and prospective entrant - have the same cost structure Total cost: TC = q2 + 5q + 25 Marginal cost: MC = 2q + 5 Average total cost: ATC =q+5+25/q Furthermore, the market demand is given by P = 105 - Q a. If the current market price is $45, what is the quantity each firm should produce to maximize its profit? b. What is the size of the industry with current market price of $45? That is, how many firms are there in the short-run? c. Given the current market price of $45 in the short-run, the profit of each firm is positive. What do you expect to happen in the long-run? d. What is the breakeven price of each firm? e. If there are new firms entering the industry in the long-run, what is the quantity produced by all firms in the market? f. How many firms are there in the industry in the long-run and how many units each firm is producing? g. Given the number of firms in the long-run found in above sub-question, what is the industry supply curve? Due to environmental law infraction, a fixed amount of penalty will result in [ lower / the same ] profit-maximizing quantity of output, while a penalty dependent on the quantity produced will result in [ lower / the same ] profit-maximizing quantity of output
