The supply and demand curves for mousetraps cross at a price of $10 apiece. There is and always has been a price ceiling of $6 per mousetrap. Now the government imposes an excise tax of $2 per mousetrap (while maintaining the $6 price ceiling). Illustrate the gains and losses to all relevant groups, and illustrate the deadweight loss due to the excise tax. Hint: You don't have to move the supply curve to solve this problem.)
