For this problem you'll make use of a two-period model like the one in Figure 8.4. Suppose each period's net marginal benefit curve for oil is a straight line with a vertical intercept of $100 and a horizontal intercept of 50 barrels. Assume the discount rate is zero. What is the dynamically efficient allocation in each period if the total quantity of oil is 120 barrels? What is the dynamically efficient allocation in each period if the total quantity of oil is 60 barrels? Illustrate your answers with graphs.
