Study Notes
External Economies of Scale
- A company experiences external economies of scale when its size leads to preferential treatment, often by governments.
- Examples include tax breaks to attract job creators or infrastructure development subsidized by developers.
- Large companies can also partner with universities for discounted research and development.
- Small businesses can benefit from geographic economies of scale by clustering together in specific areas, like artists, galleries, and restaurants in an art district.
Producers Equilibrium - Expansion Path
- An isoquant represents combinations of two inputs that yield the same output level.
- An isocost line displays the various combinations of labor and capital that can be purchased with a given budget.
- Producer equilibrium occurs when a firm minimizes the cost of producing a given output or maximizes output with a fixed input budget.
- This is achieved when the ratio of marginal product to price is equal for both inputs (MPL/PL = MPK/PK).
- The expansion path connects the optimal input combinations as production scales up, representing the least-cost combinations for each output level.
Technical Progress and Its Implications
- Technical progress refers to advancements in production methods that allow more output from the same inputs.
- Neutral technical progress equally increases the marginal productivity of labor and capital.
- Labor-augmenting technical progress boosts the marginal productivity of labor more than capital.
- Capital-augmenting technical progress increases the marginal productivity of capital more than labor.
Cobb-Douglas Production Function
- Developed by Wicksell, it was statistically tested by Cobb and Douglas using US manufacturing data from 1899 to 1922.
- It's a homogeneous function, meaning output changes proportionally with the input factors.
- The Cobb-Douglas function exhibits constant returns to scale, meaning doubling inputs doubles output.
Cost Analysis
- A production function shows how much output a firm can produce with its resources.
- Profit maximization is achieved by producing at the output level that maximizes total revenue minus total cost.
Cost Concepts
- Opportunity cost is the value of the best alternative use for resources.
- Explicit cost is the actual money paid for resources, including wages, materials, and rent.
- Implicit cost is the foregone value of resources owned by the firm, like the lost income from not renting out company-owned property.
- Economic cost encompasses both explicit and implicit costs and focuses on future costs relevant to decision-making..
- Social cost represents the total cost to society, including external costs borne by the community from production, such as pollution.
- Sunk Cost is an unrecoverable cost already incurred and irrelevant to current decision-making.
Determinants of Short-Run Cost
- Fixed cost (FC) remains constant regardless of output, including rent, equipment, and building costs.
- Variable cost (VC) varies directly with output, incorporating wages, materials, and energy expenses.
- Total cost (TC) is the sum of fixed and variable costs. (TC = FC + VC)
- Average cost (AC) is the total cost per unit of output (AC = TC/Q).
- Average variable cost (AVC) is the variable cost per unit (AVC = VC/Q).
- Average fixed cost (AFC) is the fixed cost per unit (AFC = FC/Q).
- Marginal cost (MC) is the additional cost of producing one more unit (MC = ΔTC/ΔQ).
Short-Run Cost Output Relationship
- The fixed cost curve is horizontal as fixed costs don't change with output.
- The total variable cost (TVC) curve slopes upwards as output rises because more variable inputs are required.
- The total cost (TC) curve also slopes upwards, but it's higher than the TVC curve because it includes fixed costs.
- The shape of average cost curves (AC, AVC, AFC) is influenced by the relationship between total costs and output.
Long-Run Cost
- All costs are variable in the long run, as all factors of production can be adjusted.
- There are no fixed costs in the long run.
- Long-run average cost (LAC) is the envelope of all short-run average cost curves (SAC).
- The LAC curve represents the minimum average cost for producing each output level in the long run.
Revenue
- Total revenue (TR) is the total income from selling goods and services (TR = P x Q).
- Average revenue (AR) is the revenue per unit of output (AR = TR/Q = P).
- Marginal revenue (MR) is the increase in total revenue from selling one more unit (MR = ΔTR/ΔQ).
Break-Even Analysis
- Break-even analysis studies the relationship between total cost (TC) and total revenue (TR).
- The break-even point (BEP) is the output level where TC = TR, resulting in zero profit.
- BEP is calculated as TFC / (P - AVC).
- Output below BEP results in a loss, while output above BEP generates profit.
Margin of Safety
- Margin of safety measures how much sales or output can decrease before reaching the break-even point.
- It's calculated as (Actual Sales - BEP) / Actual Sales.
Uses of Break-Even Analysis
- Determine the selling price needed for desired profits.
- Calculate the sales volume required for a specific return on investment.
- Forecast costs and profits based on output changes.
- Guide decisions on sales mix.
- Compare profitability across firms.
- Analyze costs and revenue across various output levels.
