💰 Production & Costs

Part 1 of 7 — Cost Curves and Production Decisions

The Production Function

A production function shows the relationship between inputs and outputs:

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

Per-Unit Cost Curves

Critical Relationships

$MC \text{ intersects AVC and ATC at their minimum points}$

Why? Same logic as MP/AP:

• When MC < ATC → ATC is falling (adding units cheaper than average)
• When MC > ATC → ATC is rising (adding units costlier than average)
• When MC = ATC → ATC is at minimum

Applied Recall ✍️

1. Total cost equals fixed cost plus _______ cost.

2. MC intersects ATC at ATC's _______ point.

3. AFC always _______ as output increases because fixed costs are spread over more units. (increases/decreases)

Cost Classification 🔍

Short Run vs. Long Run

Economies and Diseconomies of Scale

In the long run, the LRATC (Long-Run Average Total Cost) curve shows:

🔑 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.
