Average fixed cost, average variable cost, average total cost, and marginal cost curves

Explain how each of the following will affect the average fixed cost, average variable cost, average total cost, and marginal cost curves faced by a steel manufacturer:

1. New union agreement increases hourly pay.
2. Local government imposes an annual lump-sum tax per plant.
3. Federal government imposes a "stack tax" on emission of air pollutants by steel mills.
4. New steel-making technology increases productivity of every worker.

Solution Summary

A study of average fixed cost, average variable cost, average total cost, and marginal cost curves is embedded.
