At time t = 0, the monopolist decides what amount I 0 to invest on cost reduction, and at time t = 1 what quantity q of products to produce. His unit production cost c ( I ) > 0 is decreasing and convex in I . Profits are realized at time t = 1. Throughout this problem, assume that p ( q ) and c ( I ) are such that the maximizations are concave and the solutions have strictly positive production and investment. (i) Formulate the monopolists profit-maximization problem and determine the corresponding first- order necessary optimality conditions. (ii) Provide the social-welfare function W ( q,I ) as a function of the monopolists decision variables q and I . Compare the monopolists (second-best) choice of (....
