Richard Andreas Werner (born January 5, 1967) is a German banking and development economist who is a university professor at De Montfort University.
He has proposed the "Quantity Theory of Credit", or "Quantity Theory of Disaggregated Credit", which disaggregates credit creation used for the real economy (GDP transactions) on the one hand, and financial transactions on the other hand. In 1995, he proposed a new monetary policy to swiftly deal with banking crises, which he called 'Quantitative Easing', published in the Nikkei. His 2001 book 'Princes of the Yen' was a number one general bestseller in Japan. In 2014 he published the first empirical evidence that each bank creates credit when it issues a new loan.
