CHAPTER 8: Short-Run Costs and Output Decisions SHORT-RUN COSTS AND OUTPUT DECISIONS You have seen that firms in perfectly competitive industries make three specific decisions. DECISIONS are based on INFORMATION 1. The quantity of output to supply 1. The price of output 2. How to produce that output (which technique to use) 2. Techniques of production available* 3. The quantity of each input to demand 3. The price of inputs* *Determines production costs FIGURE 8. 1 Decisions Facing Firms © 2007 Prentice Hall Business Publishing Principles of Economics 8 e by Case and Fair 3

CHAPTER 8: Short-Run Costs and Output Decisions COSTS IN THE SHORT RUN When an independent accountant works until late at night, he faces diminishing returns. The marginal cost of his time increases. In the short run, every firm is constrained by some fixed input that (1) leads to diminishing returns to variable inputs and (2) limits capacity to produce. As a firm approaches that capacity, it becomes increasingly costly to produce successively higher levels of output. Marginal costs ultimately increase with output in the short run. © 2007 Prentice Hall Business Publishing Principles of Economics 8 e by Case and Fair 14

CHAPTER 8: Short-Run Costs and Output Decisions COSTS IN THE SHORT RUN The Relationship Between Average Total Cost and Marginal Cost The relationship between average total cost and marginal cost is exactly the same as the relationship between average variable cost and marginal cost. If marginal cost is below average total cost, average total cost will decline toward marginal cost. If marginal cost is above average total cost, average total cost will increase. As a result, marginal cost intersects average total cost at ATC’s minimum point, for the same reason that it intersects the average variable cost curve at its minimum point. © 2007 Prentice Hall Business Publishing Principles of Economics 8 e by Case and Fair 22

Sometimes referred to as explicit costs. - Economic costs Costs that include the full opportunity costs of all inputs. These include what are often called implicit costs. - Total fixed costs Costs that do not depend on the quantity of output produced. These must be paid even if output is zero. TFC Total variable costs Costs that vary with the level of output. TVC Total cost The total economic cost of all the inputs used by a firm in production. Average fixed costs Fixed costs per unit of output. AFC = TFC/q Average variable costs Variable costs per unit of output. AVC = TVC/q Average total costs Total costs per unit of output. Marginal costs The increase in total cost that results from producing one additional unit of output. TC = TFC + TVC ATC = TC/q ATC = AFC + AVC MC = DTC/Dq © 2007 Prentice Hall Business Publishing Principles of Economics 8 e by Case and Fair 23

OUTPUT DECISIONS: REVENUES, COSTS, AND PROFIT MAXIMIZATION CHAPTER 8: Short-Run Costs and Output Decisions TOTAL REVENUE (TR) AND MARGINAL REVENUE (MR) total revenue (TR) The total amount that a firm takes in from the sale of its product: the price per unit times the quantity of output the firm decides to produce (P x q). marginal revenue (MR) The additional revenue that a firm takes in when it increases output by one additional unit. In perfect competition, P = MR. © 2007 Prentice Hall Business Publishing Principles of Economics 8 e by Case and Fair 25

CHAPTER 8: Short-Run Costs and Output Decisions OUTPUT DECISIONS: REVENUES, COSTS, AND PROFIT MAXIMIZATION As long as marginal revenue is greater than marginal cost, even though the difference between the two is getting smaller, added output means added profit. Whenever marginal revenue exceeds marginal cost, the revenue gained by increasing output by one unit period exceeds the cost incurred by doing so. The profit-maximizing perfectly competitive firm will produce up to the point where the price of its output is just equal to short-run marginal cost—the level of output at which P* = MC. The profit-maximizing output level for all firms is the output level where MR = MC. © 2007 Prentice Hall Business Publishing Principles of Economics 8 e by Case and Fair 27
