The Conference was held under the term of office of my predecessor, Jaime Caru- ana, who provided firm backing for the event and followed the preparation of the programme and all related organisational work very closely. The Conference enabled participants to discuss in depth and with a long-term perspective the main issues surrounding central banking today in the areas of mon- etary policy, payment systems and financial stability. A discussion on current mac- roeconomic imbalances and their impact on world economic trends, with particu- lar focus on central banks’ tasks, added an appropriate shorter-term perspective of present economic policy challenges to the programme. This volume presents the Conference proceedings which, I believe, will contrib- ute to promoting discussion and understanding of the main challenges currently facing central banks and, hopefully, to inspiring possible policy-making improve- ments. We appreciate the outstanding contributions of all those who participated in the symposium, helping shed light on very complex and relevant topics. Finally, let me convey my special thanks to all the staff involved in the design and organisa- tion of the conference. Introduction: conference summary Santiago Fernández de Lis and Fernando Restoy1 Banco de España his book contains papers and proceedings from the Conference organ- Tised on 8-9 June 2006 to celebrate the 150th anniversary of the adoption of the name Banco de España by the Spanish Central Bank. On this occasion, dis- tinguished public officials, central bankers, academics and financial market par- ticipants met in Madrid to exchange views on the changes in the role played by central banks in the recent past and the challenges ahead in the new century. The Conference permitted participants to discuss in depth the main issues currently shaping the monetary policy debate, along with other matters of great relevance to central bankers. In particular, the programme included sessions on Payment and Security Settlement Systems and Financial Stability. Moreover, there was a panel discussion on how current macroeconomic imbalances affected the economic out- look and the extent to which this was relevant for central banks. In what follows we summarise the papers presented and the discussions held at the Conference. Monetary Policy In the session on monetary policy, chaired by Governor Jaime Caruana, Alan Blinder presented an issues note dealing with up to sixteen relevant questions. The paper contained what proved to be relatively uncontroversial arguments in favour of collegial monetary policy decision-making committees, the involvement of central banks in banking supervision, the gradualist approach for interest rate decisions, the need to lead rather than follow markets and other issues. The commentators, however, focused their remarks on a few questions on which they presented their own nuances or sometimes contradictory views. These mainly related to the objective function of 1 We wish to thank all staff involved in the organisation of the conference.

Regarding the loss function for central banks, Blinder made a case for central banks becoming more transparent about their policy objectives. In that respect he set out different practical and theoretical arguments which, in his view, would ad- vise central banks to adopt something close to a quadratic loss function in which both inflation and unemployment (or output) deviations from target would ap- pear as arguments. He would however accept that, in a systemic crisis scenario, central banks should depart from the regular objective function and give priority to financial stability considerations. Governor Vítor Constâncio expressed reservations on the proposal to ask cen- tral banks to make explicit their own loss functions. First, using results by Michael Woodford, he highlighted several theoretical points. In particular, he reminded the audience that a loss function between inflation and the output gap was only a good approximation to consumers’ welfare under specific assumptions, such as the absence of frictions other than sticky prices and the presence of cost-push shocks. Moreover, he recalled the practical difficulties of deriving robust estimates of the output gap. As a consequence, he preferred central banks not to be committed to a specific loss function or to a concrete instrument rule. ECB Vicepresident Lucas Papademos considered that the quadratic loss function proposed by Alan Blinder did not permit a realistic description of central bankers’ behaviour and introduced unnecessary constraints. In particular, he stressed that the ECB did use a hierarchical ordering of objectives – in which price stability had an overriding importance – and recalled the underlying proposition that, in general, price stability contributed to reducing output volatility. A second issue, related to some extent to the previous one, was the use of either headline or core inflation in the definition of central bank
