Homework 3: 
Due Tuesday, Feb 15.

The demand was the same in all four rounds.

1. When the seller pays a *15 tax in the event of a sale, what happens to the seller's cost?  
   To a buyer's value?

2. When the buyer pays a *15 tax in the event of a sale, what happens to the buyer's value?  
   To a seller's cost?

3. Draw the supply (marginal cost) for experiment 1.1, and the demand.  Add the supply curve 
   for experiment 1.2, where the seller paid a *15 tax.

4. Now repeat problem 3, but with experiments 1.1 and 1.4.  (That is, draw the demand 
for both experiments, and the supply). 

5. Fill in this table:

			1.1		1.2		1.3		1.4

6. Does it matter if the tax is imposed on the buyer or the seller?  Why, or why not?

7. If the elasticity of demand is 2, and the price goes up by 15%, what happens to 
the quantity demanded?

8. Suppose the elasticity of demand is 2 and the elasticity of supply is 3.  A tax of 
10% is imposed.  What happens to the buyer's price?  The seller's price?  Illustrate 
your answer with a diagram.
