Using predictive value for self-service sales for New Jersey and Oregon Johnson and Romeo (2000) estimate that the ban in those two states raised the price by approximately $.03-$.05 per gallon. Why did the ban effect the price? Illustrate using a figure and explain. Show the welfare effects in your figure. Use a table to show who gains or loses.
