Hyman Minsky

Minsky is often 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. Provided by Wikipedia
