External reference pricing goes global

Do you know how drug prices are set in Guam, Kiribati or Micronesia? Or whether countries like Bhutan, Papua New Guinea and Uzbekistan use external reference pricing (ERP)? If not, you're in good company. The World Health Organization and Health Action International have no idea either, and have asked people living in 39 countries around the world to let them know whether they operate any kind of drug pricing systems, and if so whether these include ERP.
