The government is considering two policies for regulating the market for gasoline. Both policies would reduce the total amount of gasoline sold from 140 billion gallons/year to 120 billion gallons/year. However, policy A would increase the price to consumers by 50 cents per gallon while policy B would hold the price constant. Use the concept of consumer surplus to explain which policy consumers would prefer, and how much better off they would be under this policy than under the other policy.
