Central Bank and Price Stability: Is a Single Objetive Enough?

Current developments in monetary theory, coupled with the recent practical experience of many and diverse central banks, suggest a number of basic tenets that could be regarded as effective guideposts in the search for successful practices that could contribute to attain and to sustain macroeconomic stabilization. While common sense, the myriad of accompanying circumstances within which policies and institutions develop, tend to confound their significance and to blur their basic meaning and implications. The purpose of this paper is to review and revisit, in the light of prevailing experience, the state of the art regarding monetary and central banking policies and analyze, by outlining these experiences in the form of seven basic principles, their significance for the achievement and the maintenance of macroeconomic stabilization. While each of these principles can be reviewed independently, they are, of course closely linked. The paper first scrutinizes the manner in which the literature has dealt with these issues and, in light of recent experiences, attempts to integrate them into an unified framework and to draw a number of policy lessons and theoretical implications.
