The Market for runcible spoons is characterized by the following pair of equations:

Q = - 100 + 10 P 

Q = 200 - 5 P      

1. In the boxes above indicate which is the supply curve and which is the demand curve.

2. What are the equilibrium price and quantity in the market for runcible spoons? Enter your answers in the boxes below.

Price =   Quantity =

 3. What is the amount of consumer surplus in the market for runcible spoons?

4. What is the amount of producer surplus in the market for runcible spoons?

5. What is the value of economic surplus? (This can be understood as the size of the economic pie that is shared by producers and consumers)

6. A price ceiling of P = 15 is imposed on the market for runcible spoons.  What will be the quantity demanded under the price ceiling?

7. With a price ceiling of P = 15 what will be the quantity supplied?

8. At the quantity supplied with the price ceiling of P = 15, what is the price that the marginal consumer would be willing to pay for a runcible spoon? Put another way, what is the reservation price for the 'last' customer purchasing a runcible spoon?  Reservation price =

9. What is the amount of producer surplus when there is a price ceiling of P = 15? Producer Surplus =

10. Has producer surplus increased, decreased, or remained the same? What is the amount of the change?

11. What is the amount of consumer surplus when there is a price ceiling of P = 15? Consumer surplus =

12. Has consumer surplus increased, decreased, or remained the same? What is the amount of the change?

13. What is the amount of total economic surplus when there is price ceiling of P = 15? Economic Surplus =

14. Has total economic surplus increased, decreased or remained the same? What is the amount of the change? The amount of this change is known as deadweight loss.

15. Some consumers have been made worse off as a result of the imposition of the price price ceiling. True False 

16. When comparing the free market result with the price ceiling result, the slice of the pie received by the marginal consumer has increased, decreased, or remained the same.

17. Producers have been made worse off as a result of the price ceiling. All, some, or none.

18. In a complete reversal of policy the local government eliminates the price ceiling and instead imposes a price floor.  The price floor is set at P = 25.  When there is a price floor of P = 25 what is the amount of deadweight loss?

19. In comparison to the free market case in which there is neither a price ceiling nor a price floor, the effect of the price floor of P = 25 is make all, some, none of the original producers better off, worse off, or unchanged and all, some, none of the original consumers better off, worse off, or  unchanged?
