Hyman Minsky
Hyman Philip Minsky (September 23, 1919 – October 24, 1996) was an American economist, a professor of economics at Washington University in St. Louis, and a distinguished scholar at the Levy Economics Institute of Bard College. His research attempted to provide an understanding and explanation of the characteristics of financial crises, which he attributed to swings in a potentially fragile financial system. Minsky is sometimes described as a post-Keynesian economist because, in the Keynesian tradition, he supported some government intervention in financial markets, opposed some of the financial deregulation of the 1980s, stressed the importance of the Federal Reserve as a lender of last resort and argued against the over-accumulation of private debt in the financial markets.Minsky's economic theories were largely ignored for decades, until the subprime mortgage crisis of 2008 caused a renewed interest in them.
