Structured Notes for The Structure of Costs in the Long Run
A scan-friendly outline of Economics 3e 7.3 organized around Long-Run Average Cost, Economies of Scale, Diseconomies of Scale.
- In the long run, firms can adjust all inputs, so fixed costs no longer constrain production in the same way.
- Track the section's working concepts: Long-Run Average Cost, Economies of Scale, Diseconomies of Scale, Constant Returns.
- Use the outline to move from textbook wording into recall-ready relationships.
Key takeaways
- In the long run, firms can adjust all inputs, so fixed costs no longer constrain production in the same way.
- Economies of scale occur when average cost falls as output expands.
- Diseconomies of scale occur when average cost rises as output expands.
