Assume the coal resource is in fixed supply and its stock is 15 units of coal. Assume 2 periods of extraction: present and future and a discount rate of r = 10%. The demand function is given by MB = 10 - 0.5q and the supply function is given by a fixed MC cost of extraction MC = $5/unit of coal. a) What is the optimal extraction rate in a static setup of the problem? Show numerically. Why cannot it be applied to this resource? b) What is the optimal extraction rate each period in a dynamic setup of the problem? Show numerically. c) What are the prices and MUC-marginal user costs each period? Show numerically.
