1) Prove the following relationship between change in price and change in specific tax rates:

Answer: See the appendix to the chapter.

2) When the price of broadband access capacity increases by 10%, commercial customers buy about 3.8% less capacity. What is the elasticity of demand for broadband access? Is demand at the current price elastic or inelastic?

Answer:

elasticity is percent change is quantity over percent change in price. this the elasticity for broadband is 3.8/10 = 0.38.

0.38 is less than 1, thus the demand for broadband is inelastic.

3) Would you prefer for a 15 cent per gallon tax on milk to be collected from milk producers or from consumers at the store? Why?

Answer: It doesnt matter. The outcome is the same

4) Use calculus to prove that the elasticity of demand is a constant everywhere along the demand curve whose demand function is given by:

Answer:

5) The supply curve is Q = g + hp. Derive a formula for the elasticity of supply in terms of p (and not Q). Now give one entirely in terms of Q.

Answer:

6) Use math to show that, as the supply curve at the equilibrium becomes nearly perfectly elastic, the entire incidence of a specific tax will fall on consumers.
