Production costs and economies of scale are crucial concepts in understanding how firms operate. As companies grow, they often benefit from lower average costs due to specialization and efficiency gains. However, there's a sweet spot where costs are minimized.
Long-run and short-run cost curves help visualize these relationships. The long-run average cost curve shows the lowest possible costs at different output levels, while short-run curves represent costs with fixed production scales. Understanding these helps firms make smart production decisions.

- Economies of scale decrease in long-run average costs as output increases due to specialization, more efficient technology, and volume discounts on inputs
- Diseconomies of scale increase in long-run average costs as output increases due to coordination problems, bureaucratic inefficiencies, and scarcity of inputs
- Constant returns to scale long-run average costs remain constant as output increases
- Minimum efficient scale (MES) lowest output level where long-run average costs are minimized
Long-run and short-run average cost curves
- Long-run average cost (LRAC) curve lowest possible average cost for each output level, allowing for changes in the scale of production derived from the envelope of the short-run average cost (SRAC) curves U-shaped, reflecting economies and diseconomies of scale
- Short-run average cost (SRAC) curves average cost for each output level, holding the scale of production constant each SRAC curve represents a different scale of production U-shaped, reflecting the law of diminishing marginal returns
- Long-run marginal cost (LRMC) change in long-run total cost resulting from a one-unit increase in output intersects the LRAC curve at its minimum point, representing the MES
Production Technology and Input Prices
Input prices and choice of production technology
- Firms choose production technology that minimizes costs for a given level of output
- Changes in input prices alter the relative costs of different production technologies increase in labor price encourages firms to adopt more capital-intensive technologies decrease in capital price encourages firms to adopt more capital-intensive technologies
- Substitution effect as the price of an input rises, firms substitute away from that input and towards relatively cheaper inputs (labor, capital)
- Scale effect as input prices change, the optimal scale of production may change, leading firms to adjust their output levels
- Firms may face short-run constraints in changing production technology due to fixed costs and long-term contracts (leases, supplier agreements)
Key Terms to Review (20)
Economies of Scale: Economies of scale refer to the cost advantages that businesses can exploit by expanding their scale of production. As a company increases its output, its average costs per unit typically decrease due to more efficient utilization of resources, specialized equipment, and division of labor.
Marginal Revenue: Marginal revenue is the additional revenue a firm earns by selling one more unit of a good or service. It represents the change in total revenue resulting from a one-unit increase in the quantity sold. Marginal revenue is a crucial concept in understanding how firms make output and pricing decisions across various market structures.
Diseconomies of Scale: Diseconomies of scale refer to the increase in average cost per unit that can occur when a company or industry expands its scale of production beyond an optimal level. This phenomenon is the opposite of economies of scale, where average costs decrease as output increases.
Marginal Cost: Marginal cost is the additional cost incurred by a firm when producing one more unit of a good or service. It represents the change in total cost that results from a small increase in output. Marginal cost is a crucial concept in understanding a firm's production decisions and profitability across various market structures.
Optimal Plant Size: Optimal plant size refers to the ideal scale of production that allows a firm to minimize its long-run average costs and maximize efficiency. It is a critical concept in the analysis of production and costs in the long run.
Long-Run Expansion Path: The long-run expansion path is a graphical representation of the combinations of inputs that a firm will use to produce different levels of output in the long run, where all inputs can be varied. It shows the firm's optimal input choices as output changes, given the firm's production technology and input prices.
Returns to Scale: Returns to scale refers to the behavior of output as a firm increases all of its inputs by the same proportion. It describes how a proportional change in all inputs leads to a change in output, and it is an important concept in the analysis of production and costs in both the short run and long run.
Long-Run Average Cost: Long-run average cost (LRAC) is the average cost of production per unit of output when all factors of production are variable, allowing the firm to adjust its scale of operations to achieve the most efficient level of output. It represents the lowest possible average cost of production in the long run.
LRAC (Long-Run Average Cost): LRAC, or Long-Run Average Cost, is a fundamental concept in microeconomics that represents the average cost of production for a firm in the long run, when all inputs can be varied. It is a crucial consideration for firms as they make decisions about production and expansion in the long term.
Constant Returns to Scale: Constant returns to scale is a property of a production function where an increase in all inputs by a certain factor leads to an equal proportional increase in output. In other words, doubling all inputs will exactly double the output.
Average Variable Cost: Average variable cost is the total variable costs divided by the quantity of output produced. It represents the average cost of each additional unit of production, excluding fixed costs, and is an important consideration for firms in the long run and when making output decisions in perfect competition.
Isoquant Map: An isoquant map is a graphical representation of the various combinations of inputs that can produce the same level of output for a firm. It is a useful tool in the analysis of production and cost in the long run, as it allows for the visualization of the tradeoffs between different factors of production.
Isocost Line: An isocost line is a graphical representation of all the combinations of two inputs that a firm can purchase with a given total cost or budget. It shows the different combinations of inputs, such as labor and capital, that a firm can use to produce a given level of output while spending the same total amount of money.
SRAC: SRAC, or Short-Run Average Cost, is a key concept in the study of costs in the long run. It represents the average cost of producing each additional unit of output when at least one input is fixed, reflecting the law of diminishing returns in the short run.
Minimum Efficient Scale: Minimum efficient scale (MES) is the smallest scale of production at which a firm can achieve the lowest possible per-unit cost of production. It represents the point where economies of scale are exhausted, and any further increase in output does not result in a significant reduction in average costs.
Envelope Theorem: The envelope theorem is a fundamental concept in microeconomic theory that describes how changes in exogenous parameters affect the optimal choice of a decision variable. It provides a way to analyze how the optimal solution to an optimization problem varies with changes in the parameters of that problem.
Cost-Minimizing Input Combination: The cost-minimizing input combination refers to the optimal combination of inputs, such as labor and capital, that a firm should use to produce a given level of output at the lowest possible cost. This concept is crucial in the context of long-run cost analysis, as firms aim to minimize their production costs to maximize profits.
Long-Run Total Cost: Long-run total cost refers to the total cost of production when a firm can vary all of its inputs, including the size of its facilities and equipment. It represents the minimum cost of producing a given level of output when the firm has the flexibility to adjust all factors of production, including the scale of its operations.
Short-Run Average Cost: Short-run average cost (SRAC) refers to the average cost of production in the short-run, which is the period of time where at least one factor of production is fixed. SRAC is a crucial concept in understanding a firm's cost structure and decision-making process in the short-run.
LRTC: LRTC, or Long-Run Total Cost, is the total cost of production for a firm in the long run. The long run is a period of time in which all factors of production, including capital equipment and facilities, can be adjusted. This allows the firm to choose the optimal combination of inputs to minimize costs and maximize profits.
