Consider there is a firm called Health-R-Us that is a monopoly. How does Health-R-Us decide the price to charge and quantity to sell of the goods it has a monopoly on? Illustrate your answer using a fully labelled and explained market diagram. Assume Health-R-Us is making monopoly profits and illustrate these on the same diagram. In addition, indicate the area on your diagram that illustrates the efficiency cost (the dead weight loss) of the monopoly, and explain why this dead weight loss arises.
