A new chemical has been discovered that can be produced at a constant marginal cost of MC = $10 by its patent holder, Johnson, Inc. There are no fixed (capital) costs in this question. Two industries, A and B, find the chemical, Cloreen, to be useful in their production processes. Industry A has a demand for Cloreen of QA = 100 - PA. Industry B's demand is QB = 60 - Pg. a) [4 points) If Johnson can prevent resales between industries A and B, what prices will it charge to A and B? It can be assumed that the patent gives Johnson monopoly power. What quantities will be sold to the two industries, and what will be Johnson's profit? b) [4 points] Assume now that it is illegal for Johnson to charge different prices to A and B. What price will Johnson now charge? What is Johnson's total quantity sold? What will its profit be? c) [4 points) Is total economic surplus (or net economic benefit) higher in part (a) or (b)? What is the difference in total surplus in the two cases? d) 3 points) Draw a well-labelled graph (or graphs) to guide your calculations in parts (a)-c).
