Problem

Suppose the demand for insulin pumps is Q^D = 2,000 and the supply of insulin pumps is Q^S = 0.5P - 1,000. What is the price that sellers receive per pump? Suppose the government imposes a tax of $400 per pump on sellers. What after-tax price per pump do sellers receive?

Suppose the market for soda is represented by the supply and demand equations:
Q^S = 35P - 39.75 and Q^D = 10.25 - 5P, where P is price per bottle and Q measures bottles per second.

1. What are the values of consumer and producer surplus?

2. If the government imposes a $0.50 tax per bottle, what are the values of consumer and producer surplus?

3. What is the deadweight loss from the tax? How much revenue does the tax yield?
