Producer Surplus and Quasi-Rent

Producer surplus is revenue over variable cost, the area between price and the supply curve, 32 at the worked price of 16, and the portion covering fixed cost is the quasi-rent, the return to the fixed factor that entry and exit arbitrage over the long run.

2. Decomposing the surplus

3. Surplus and supply together

4. The module's midpoint

The module's midpoint

5. The surplus computation

At price 16 with supply 4, what is the firm's producer surplus?

6. The marginal unit's contribution

Why does the last unit supplied contribute zero surplus?

7. Quasi-rent meaning

What is the quasi-rent of the fixed factor here?

8. The envelope twin

How does producer surplus grow as price rises along the supply curve?

9. Profit from surplus

Subtract the fixed cost 36 from producer surplus 32, and write the profit.

10. Revenue at the tangency

Compute revenue at price 16 and quantity 4, and write the number.

11. The variable bill at four

At price 16 the firm supplies 4 units earning producer surplus 32 on revenue 64. What was its variable cost?

12. Surplus decomposed

Producer surplus is 32, profit is minus 4. What is the relation?

13. Surplus growth along the curve

Producer surplus is 8 at price 10 and 32 at price 16. What does the growth pattern show?

14. The fixed factor idled

If the price fell all the way to 7, what happens to the quasi-rent?

15. Supply at twelve

Using q equals 2 plus root of p minus 4 over 3, compute supply at p of 12, and write the number to two decimals.

16. Variable cost at three

For the cubic family, compute total variable cost at q of 3, and write the number.
