Study Notes
Production Theory
- Describes how firms make cost-minimizing decisions, relating cost to output.
- Production decisions are similar to consumer purchasing decisions, each involve three steps: Production Technology, Cost Constraints, and Input Choices.
Factors of Production
- Inputs to the production process, such as labor, capital, and materials.
Production Function
- Shows the highest output achievable for given input combinations.
- Inputs and outputs are considered flows (measured over time), not stocks.
- Inputs like labor, raw materials, or energy are consumed over a period of time to produce goods/services.
- Outputs, like goods/services likewise are measured over time.
- The production function q = F(K, L) assumes constant technology.
Short Run vs. Long Run
- Short run: period where at least one factor of production is fixed and cannot be changed.
- Long run: period where all factors of production are variable.
Average and Marginal Products
- Average product: output per unit of input.
- Marginal product: additional output from increasing an input by one unit.
Law of Diminishing Marginal Returns
- As more of one input is used (with other inputs fixed), the resulting additions to output eventually decrease.
Isoquant
- Curve showing all possible input combinations producing the same output.
Isoquant Map
- Graph combining multiple isoquants, illustrating a production function.
Marginal Rate of Technical Substitution (MRTS)
- Quantifies the amount one input can be reduced while using one more unit of another, to maintain the same output.
- MRTS = -AK/AL = MP₁/MPK
Returns to Scale
- Rate at which output expands as all inputs increase proportionately.
- Increasing returns: output more than doubles when inputs double.
- Constant returns: output doubles when inputs double.
- Decreasing returns: output less than doubles when inputs double.
Cost of Production
- Economic cost: comprises explicit and implicit costs, including opportunity cost.
- Accounting cost: only explicit costs.
- Explicit costs: require direct outlay of money (e.g., raw materials, wages).
- Implicit costs: do not involve direct cash outflow (e.g., forgone wages, rent).
- Sunk costs: past expenditures not recoverable (shouldn't affect current decisions). amortization treats sunk costs as annual costs.
Marginal Cost (MC)
- Change in total cost due to producing one more unit.
- MC is equal to the increase in variable cost or the total cost from an extra unit of output.
- MC = ΔTC/Δq
Average Total Cost (ATC), Average Fixed Cost (AFC), and Average Variable Cost (AVC)
- ATC = TC/q
- AFC = TFC/q
- AVC = TVC/q
Cost Curves
- Average total cost (ATC) curves are U-shaped
- Marginal cost (MC) curve intersects the ATC curve at its minimum.
Long-Run Average Cost (LAC) and Short-Run Average Cost (SAC)
- LAC curves relate average cost to output when all inputs, including capital, are variable.
- SAC curves relate average cost to output when the capital level is fixed.
Economies and Diseconomies of Scale
- Economies of scale: LRAC falls as output increases, frequently due to specialization and bulk purchasing.
- Diseconomies of scale: LRAC rises as output increases, potentially due to managerial inefficiencies.
Production, Cost, and Revenue
- Profit = Total Revenue - Total Cost.
- Revenue: amount a firm receives for its output.
- Cost: expenses for producing the output.
- Profit maximisation: Producing to a level where Marginal Revenue (MR) equals Marginal Cost (MC).
Firm Structures: Perfect Competition vs Monopoly
- Perfect competition: Many sellers, homogenous product, easy entry/exit, no market power. Price = Marginal revenue (MR).
- Monopoly: One seller, unique product, high barriers to entry, significant market power. Price > Marginal revenue (MR).
Monopoly
- A single seller in a market with no substitute products.
- Has significant market power.
- Can set price, but output and price are determined by demand.
Price Discrimination
- Charging different prices for the same good to different groups or customers based on their willingness to pay.
