The book "Monetary Policy Strategy" by Frederic Mishkin discusses changes in how monetary policy is conducted, focusing on inflation targeting. Mishkin combines theory, evidence, and case studies to explore the importance of price stability, central bank independence, transparency, and communication in achieving economic goals. Key findings include the significance of having a nominal anchor for stable prices, the role of fiscal and financial conditions in achieving price stability, and the rationale for inflation targeting as a policy strategy.
