In 2006, a capital campaign led to the creation of a sizable endowment in order to celebrate the PIIE's 25th anniversary. Previously known as the Institute of International Economics, it changed its name that same year in recognition of Peter G. Peterson's role in the capital campaign and for his longstanding support of the Institute since the early 1980s. At its conference in New York, NY, a number of major economic figures attended: Alan Greenspan, former Federal Reserve Board Chairman; Robert Rubin, former Secretary of the Treasury; Jean-Claude Trichet, Governor of the European Central Bank, among others.
