Issue 14 of PSI’s Impact magazine is now available online. “In this issue, Impact looks under the hood to see how [non-governmental organizations (NGOs)], donors, charity watchdogs and corporations measure impact and what role measurement plays in decision-making,” according to the magazine’s website. The issue includes a feature on how pricing affects malaria treatment, expert commentary from USAID’s Ellen Starbird, and a letter from PSI President & CEO Karl Hofmann, among other articles (November 2013).
