(a) What is the quantity of the resource constraint (i.e., how much resource is available over these two periods) __________________________________________________ 

(b) What area maximizes the total net present value of Period 1 and 2 (using labels from the figure)? _______________________ 

(c) If the Marginal User Cost (MUC) in period 1 is $1.92, what is the price in period 2 of the gold?______________________________________ 

(d) What is the present value of net benefit in Period 1 if 15 units of gold were consumed in this period? ________________________________________ 

(e ) What is the present value of net benefit in Period 1 if 5 units were consumed in this period? ____________________________________

Using the two period model below for which Marginal Extraction Cost (MEC) of gold extraction is 2, inverse demand curve is PP = 8 -0.4QQ, and discount rate is rr = 0.1. Please fill in the following blanks using the figure below and information provided. (a) [1 pts] What is the quantity of the resource constraint (i.e., how much resource is available over these two periods)?
