Job Titles:
  • Senior Fellow
  • Senior Fellow at Croatan Institute
Bill Harrington is a Senior Fellow at Croatan Institute. His work centers on boosting the sustainability of the world financial system with the dual aims of rationalizing economic decision-making and avoiding bailouts. He focuses on governance decisions in the financial sector that establish the capitalization and regulation of complex finance, particularly derivative contracts and structured finance products. Bill has evaluated products in the international financial markets since 1987, most recently as a research journalist at Debtwire ABS and before that as a senior vice president and derivatives analyst at Moody's Investors Service (Moody's). He also structured derivative contracts that referenced currencies and global interest rates at Merrill Lynch and analyzed the trading patterns of these indices as an economist at The WEFA Group. Since 2011, Bill has worked to rectify the under-capitalization of the types of complex finance that started and fueled the financial crisis. He has submitted technical comments to the US Court of Appeals for the Second Circuit, US and European regulators, to US and UK legislative committees, and to rating agencies such as Fitch Ratings, Moody's, and S&P Global. Bill also provided insights regarding Moody's rating practices to the US state attorneys general who settled with the company in early 2017. Bill has self-financed this advocacy and conducts it entirely in the public domain. He regularly speaks to the press, and his work has been profiled in the New York Times, the Financial Times, the Guardian, Bloomberg, Business Insider, ProPublica, the Wall Street Journal, the Washington Post, and on the BBC and American Public Media's Marketplace. He places all work on government and other websites and actively engages regulators, market practitioners, journalists, and other parties in on-the-record dialog. Additionally, Bill serves on the Experts Board of Wikirating. Bill was born and raised in the historically significant mill city of Lowell, Massachusetts, a cradle of the US Industrial Revolution and home to many of his family. Their deep Lowell roots extend to the 1857 arrival of John and Margaret Harrington from Ireland. Six of Bill's maternal great, great grandparents also immigrated directly to Lowell from Quebec in the 1860's, from Ireland in 1870, and from England in 1871. More recently, Bill's maternal and paternal grandparents lived a few houses apart on the same street between 1944 and 1965. This 160-year history of Lowell life animates Bill's fascination with the interplay of economic cycles and human decision making. Bill and his partner John live in New York City. Bill is an avid, lefthanded tennis player. Education M.B.A., Concentration in Finance, The Wharton School of the University of Pennsylvania B.A., Economics, University of Pennsylvania
