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 policies popular in 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.
