The annual U.S. market for prescription drugs is more than $500 billion, representing almost 17% of all health care expenditures, and it is rising at an unsustainable rate. In 2017, the average American spent $1,100 per year on medications. It is, therefore, no wonder that the public and elected officials are fixated on understanding the factors leading to high prices and forging workable policy solutions. Dr. Sean Sullivan, a health economist and expert on drug pricing, will discuss the many reasons why prescription drugs cost so much in the US and the options to address the problem.
