The mid-1980s began a period that might, in retrospect, be seen as the golden age of monetary policy. Worldwide inflation rates, which had come down from the high levels reached in the 1970s, were at the lowest level seen in a long time. In the real economy, low and stable inflation went along with growth - at first, reasonable, and later, remarkable - and with reduced volatility. The term Goldilocks is sometimes used to describe this solid, sustainable situation - meaning that, like the porridge in the fairy tale, it was neither too hot nor too cold but just right. A number of fortunate circumstances contributed to the Goldilocks economy. Deregulation and globalisation, with their impact on competition and pricing power in goods and labour markets, are sometimes seen as major factors supporting the achievement and maintenance of low inflation (Rogoff (2003)).With the weakening of deregulation and globalisation, will we see the end of the golden age, which then will turn out to have been only a short episode? On the one hand, an end to the golden age would be no surprise for those who have stressed from the outset that its highly positive macroeconomic outcomes were the result, if not of luck, then of benign circumstances whose combination could not be expected to last forever (Sims and Zha (2006)). And do not recent developments already confirm this sceptical assessment of the role of central banks and monetary policy during this period? Isn't inflation rising? Doesn't the ongoing turbulence in financial markets indicate that central banks did not - or, rather, could not - prevent such developments?On the other hand, have we not seen the emergence of a policy regime that should be robust enough to continue the period of monetary stability? And would not a regime of monetary stability contribute..
