Consider our discussion on technological change. Assume for the moment that 3D printers become as cost effective as injection molding. In the long run, how does this impact firms, the industry, consumers and society? Part a) Consider the change in minimum effective scale (MES) Part b) How would the industry change Part c) How would benefit, who would be hurt?
