"The Taylor Rule" is a specialized book that deals with the implementation of monetary policy and the application of monetary rules, particularly the Taylor Rule. This rule describes how central banks should adjust their short-term interest rates in response to deviations of real GDP from its potential as well as deviations of inflation from established targets. The book provides a theoretical foundation for the Taylor Rule and explains its practical application through two real economies from the last decade. It is aimed at readers interested in econometrics and monetary policy rules, offering valuable insights into the decision-making processes of policymakers. The analysis of the Taylor Rule is supplemented by empirical examples that illustrate the relevance and applicability of this rule in modern monetary policy.
