Study Notes

Firm and Profit Maximization

Profit is calculated as Total Revenue minus Total Costs.
Total Revenue = Price × Quantity.
Average Revenue = Price.
Marginal Revenue = Price

Economic Costs

Total Costs = Explicit Costs + Implicit Costs.
Explicit Costs = Direct monetary expenses (materials, wages).
Implicit Costs = Opportunity costs of resources (foregone income, sweat equity).
Accounting Profit = Total Revenue – Explicit Costs.
Economic Profit = Total Revenue – (Explicit Costs + Implicit Costs).
Opportunity Cost = Total economic cost of using resources (explicit + implicit).

Production Basics

Production Function = Relationship between inputs (e.g., labor, capital) and output.
Labor (L) = Variable input.
Capital (K) = Fixed input (short-run).
Short-Run Production: Capital is fixed, output changes with labor input.
Long-Run Production: Both labor and capital are variable.
Total Product (TP) = Total output produced.
Marginal Product (MP) = Change in output per additional unit of input (MP = ΔQ/ΔL).
Diminishing Marginal Product = decrease in additional output as more variable input is added.

Cost Structures

Total Costs (C) = Fixed Costs (F) + Variable Costs (VC).
Fixed Costs (F) = Costs that don't change with output (e.g., rent).
Variable Costs (VC) = Costs that change with output (e.g., materials).

Average and Marginal Costs

Average Total Cost (ATC) = Total Costs / Quantity.
Average Fixed Cost (AFC) = Fixed Costs / Quantity.
Average Variable Cost (AVC) = Variable Costs / Quantity.
Marginal Cost (MC) = Increase in total cost from producing one more unit (MC = ΔC/ΔQ).

Cost Curve Analysis

Efficient Scale = Output level that minimizes Average Total Cost (ATC).
ATC Curve = U-shaped due to declining AFC and rising AVC.
MC Curve = Intersects ATC at its minimum.

Economies & Diseconomies of Scale

Economies of Scale = Long-run ATC decreases as output increases.
Diseconomies of Scale = Long-run ATC increases as output increases.

Short-Run vs. Long-Run

Short-Run = Fixed production capacity.
Long-Run = All inputs are variable.
