Several years ago, Pfizer and Warner-Lambert agreed to a $ 90 billion merger, thus creating one of the world's largest pharmaceutical companies. Pharmaceutical companies tend to spend a greater percentage of sales on R&D activities than other industries. The government encourages these R&D activities by granting companies patents for drugs approved by the Food and Drug Administration. For instance, Pfizer-Warner-Lambert spent large sums of money developing its popular cholesterol-lowering drug, Lipitor, which is currently protected under a patent. Lipitor sells for about $ 3 per pill.
a) Calculate the Lerner index if the marginal cost of producing Lipitor is $ 0.30 per pill.
b) Does the Lerner index make sense in this situation?
