Micro Unit 4, Question 9- Lump Sum vs. Per Unit

The video tutorial explains the differences between lump sum tax and per unit tax. A lump sum tax is a one-time fee that affects a firm's fixed costs, altering the average total cost but not the marginal cost. This results in unchanged price and quantity but reduced profit. In contrast, a per unit tax impacts variable costs, leading to changes in both average total cost and marginal cost. This causes an increase in price and a decrease in quantity, affecting the firm's profit margin.

Explain why marginal costs remain unchanged with a lump sum tax.
