Law professor and author Robin Feldman of UC Hastings College of the Law talks about her book Drugs, Money, and Secret Handshakes with EconTalk host Russ Roberts. Feldman argues that the legal and regulatory environment for drug companies encourages those companies to seek drugs that extend their monopoly through the patent system often with insufficient benefit for consumers. The prices for those drugs are then protected from new competition. She also argues that the pharmacy benefit management system allows drug companies to exploit consumers. The conversation concludes with a discussion of what can be done to improve the situation.
