In a recent issue of this Journal, Lin analyses a pollution control model that is designed to include adjustment costs, investment, employment and inflation. His analysis of the control theoretic solution appears to contain a number of errors which are pointed out below. Also, the model that he constructs has some awkward features in the view of this analyst. My concerns with the model are outlined in the second section of this comment. [See IAOR 37578.]
