Part 1: Core Concepts
💰 Production & Costs
Part 1 of 7 — Cost Curves and Production Decisions
The Production Function
A production function shows the relationship between inputs and outputs:
| Workers | Total Product (TP) | Marginal Product (MP) | Average Product (AP) |
|---|---|---|---|
| 0 | 0 | — | — |
| 1 | 10 | 10 | 10.0 |
| 2 | 24 | 14 | 12.0 |
| 3 | 36 | 12 | 12.0 |
| 4 | 44 | 8 | 11.0 |
| 5 | 48 | 4 | 9.6 |
| 6 | 48 | 0 | 8.0 |
Diminishing Marginal Returns
🔑 Law of Diminishing Marginal Returns: As more units of a variable input (labor) are added to a fixed input (capital), MP eventually declines.
In the table: MP peaks at worker 2 (14 units), then decreases. This is NOT because workers are lazier — it's because each worker has less capital to work with.
MP and AP Relationship
- When MP > AP: AP is rising
- When MP < AP: AP is falling
- When MP = AP: AP is at its maximum
Think of it like a batting average: if your next at-bat (marginal) is above your average, your average rises.

Cost Curves
Fixed vs. Variable Costs
| Cost Type | Changes with Output? | Examples |
|---|---|---|
| Fixed (FC) | No | Rent, insurance, salaries of managers |
| Variable (VC) | Yes | Raw materials, hourly wages, electricity |
| Total (TC) | TC = FC + VC | All costs combined |
Per-Unit Cost Curves
| Curve | Formula | Shape |
|---|---|---|
| AFC | FC / Q | Always decreasing (spreading fixed costs) |
| AVC | VC / Q | U-shaped — falls then rises |
| ATC | TC / Q = AFC + AVC | U-shaped — falls then rises |
| MC | ΔTC / ΔQ | U-shaped — falls then rises |
Critical Relationships
Applied Recall ✍️
-
Total cost equals fixed cost plus _______ cost.
-
MC intersects ATC at ATC's _______ point.
-
AFC always _______ as output increases because fixed costs are spread over more units. (increases/decreases)
Cost Classification 🔍
Short Run vs. Long Run
| Time Period | Definition | Key Feature |
|---|---|---|
| Short run | At least one input is fixed | Fixed costs exist; diminishing returns |
| Long run | All inputs are variable | No fixed costs; can change plant size |
Economies and Diseconomies of Scale
In the long run, the LRATC (Long-Run Average Total Cost) curve shows:
| Region | ATC Behavior | Cause |
|---|---|---|
| Economies of scale | LRATC falls | Specialization, bulk purchasing, better technology |
| Constant returns | LRATC flat | Neither advantage nor disadvantage of size |
| Diseconomies of scale | LRATC rises | Coordination problems, bureaucracy |
🔑 Minimum efficient scale = the smallest output where LRATC reaches its minimum. This determines whether an industry naturally has many small firms or few large ones.
