The own price elasticity of demand is the most important determinant of pricing strategy by a firm. A firm can charge a high price for its product and earn higher revenue if the demand for its product is relatively inelastic. In other words, demand inelasticity and market power go hand in hand.
What strategies should a firm adopt to make the demand for its product inelastic? Explain.
A firm practices third-degree price discrimination. With the aid of a graphical illustration, explain the firm’s pricing strategy to maximise profits.
Question 5: Jimmy has a room that overlooks, from some distance, a major league baseball stadium. He decides to
rent a telescope for $50 a week and charge his friends and classmates to use it to peep at the game for 30 seconds. He
can act as a monopolist for renting out "peeps". For each person who takes a 30 second peep, it costs Jimmy $.20 to
clean the eyepiece. Jimmy believes he has the following demand for his service:

Provide words to explain the basic reason why the price does not move up or down as costs change.arrow_forward

The market for EpiPens Consider the pharmaceutical company Mylan that produces epinephrine injection devices called EpiPens. In the presence of other firms producing substitutes for this good, the price of EpiPens is $150. Now suppose that competitors to Mylan no longer produce epinephrine injection devices, so Mylan now has pricing power in this market. As the economist on staff at Mylan, you are charged with the task of figuring out what your company's new pricing strategy should be. The following graph shows the marginal cost (MC), which is assumed to be constant, and the average total cost (ATC) of Mylan. The graph also shows the demand curve (D) for EpiPens and the marginal revenue curve (MR) once the firm has market power. On the graph, use the grey point (star symbol) to indicate the quantity of EpiPens demanded if Mylan continues to charge $150. Dashed drop lines will automatically extend to both axes.
