Suppose that a wood pulp mill is situated on a bank of the River Tay. The Private Marginal Cost (MPC) of producing wood pulp (in £ per ton) is given by the function £ MPC = 5 +0.5Y where Y is tons of wood pulp produced. In addition to this private marginal cost, an external cost is incurred. Each ton of wood pulp produces pollutant flows into the river which cause a fixed damage valued at £10. This is an external cost, as it is borne by the wider community but not by the polluting firm itself. The Marginal Private Benefit (MPB) to society of each ton of produced pulp, in £, is given by MPB = 30 - 0.5Y
(20 marks) e) Explain and show with the use of a diagram how a different shape of the Marginal Private Benefit curve could lead to the social efficient level of output being zero. (30 marks)
