The market supply in a competitive industry is p = Q and demand
is p = 100 - Q.
Production creates pollution with a social cost of $1 per unit of
output. In response to environmentalists,
the government creates a tax of $2 per unit.
(a) (9 points) Calculate the price and quantity for the competitive
equilibrium, the social optimum,
and the equilibrium with the tax.
(b) (9 points) Show these three points in a graph. Calculate the consumer surplus, producer
surplus, social cost, tax revenue and total welfare before and after the tax is imposed.
(c) (2 points) Is overall welfare improved or reduced by the
tax?

Suppose that in a perfectly competitive market, demand is given by Q=58.0-P and supply is given by Q=P-27.0. The government imposes a per-unit excise tax of $1 on the good. What is producer surplus after the tax is imposed? No units, no rounding.
