Each main part of the book—part I, ‘‘Fundamental Issues in the Conduct of Monetary Policy’’; part II, ‘‘Monetary Policy Strategy in Advanced Economies’’; part III, ‘‘Monetary Policy Strategy in Emerging Market and Transition Economies’’; and part IV, ‘‘What Have We Learned?’’—opens with a short introduction that provides a brief summary of each chapter in that part, describing how these came to be written and how they fit together. The final part of the book contains a concluding chapter that tries to put it all together by summarizing what we have learned about monetary policy during the past twenty-five to thirty years.
