This paper analyzes the change in social welfare brought about by a cost reducing technological innovation. Each firm adopts a new technology at the expense of the other firms. Hence, competitive adoption of new technology can reduce social welfare. Because a technological innovation can change market structure in different ways under different kinds of competition it can cause quantity competition to generate greater social welfare than price competition does.
