Abstract. As a result of the economic turmoil started in 2007, there is a dispute if the monetary policy implies radical changes or just a rethinking of details regarding the main framework of the monetary policy strategy. Therefore, the actual debates that I have analyzed in the article take into account, among others, the relationship of monetary policy with the one of financial stability, the analyze if the monetary policy should lean against credit bubbles or just clean after their explosion (Lean vs. Clean debate), the presence of nonlinearities in economy. Thus, monetary economy becomes more interesting and the economists need to think about a wider range of monetary policy problems than existed before.

Keywords: monetary policy; financial stability; macroprudential regulation; credit bubbles; linear quadratic framework.
