- Although 23 states barred the self-service sale of gasoline in 1968, most removed the bans by the mid-1970s. By 1992, self-service outlets sold nearly 80% of all US gas, and only New Jersey and Oregon continued to ban self- service sales. 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.(Q1) Many software companies, after years of providing unlimited free telephone technical support for their products, began to charge for these services (typically after an initial start-up period of 90 days). Most companies offer two pricing plans. For instance, Lotus Development offers users of their spreadsheet software the option of paying either (i) $2.00 per minute for telephone support or (ii) a $129 flat charge for a year of unlimited toll-free calls. Question 1: Consider a customer with a yearly (expected) demand for service support of P = 11 – 0.1Q, where P is the price per minute and Q is the number of minutes of calls made per year. How many calls would this customer make under plan (i)? Why? How many calls would he or she make under plan (ii)? What would be the annual cost to this customer under each plan? Explain your answer. Question 2: Which plan would this customer choose? Explain your answer.U(t,s) = 5t + 2s Calculate the MRSs,t (Note: Write the number in Table. Give one digit after the point. Example: 1.5).
