Unit 2: Elasticity, Consumer Choice, Costs

Lesson 7b: Production Costs in the Short Run

Outcomes - What you should learn

TOPICS:

Short Run Costs: Define Draw, Describe

OUTCOMES:

Distinguish between fixed, variable and total costs

Explain the difference between average and marginal costs

Compute and graph AFC, AVC, ATC, and MC when given total cost data

Know how and why we graph the MC "at the midpoints".

Explain how TC, TVC, and TFC relate to one another: Do TC and TVC get closer together?

Explain how AVC, ATC, and MC relate to one another

- Do ATC and AVC get closer together?

- Why does MC cross ATC and AVC at their lowest points?

Explain the shapes of the total, average, and marginal cost curves (TC, TVC, TFC, ATC, AVC, AFC, and MC)

Relate average product to average variable cost, and marginal product to marginal cost

Explain what happens to the cost curves if there is a change in fixed costs and what happens if there is a change in variable costs (what can cause cost curves to rise or fall?)
