After lunch Philip Turner from BIS and Governor Ingves will share some of their insights from the theory and practice of central banking. The day will conclude with a panel discussion chaired by professor Gerlach, on central banks’ future challenges. We are fortunate to have such prominent speakers here with us today. I hope they inspire our further research on the topic “What is a useful central bank?”. 1  Walter Bagehot (1873): “Lombard Street: A description of the Money Market”. BIS Review 154/2010  3
Obviously, if the starting point is a structural budget deficit, then the return to budget balance will require spending to grow more slowly than nominal growth or else a discretionary increase in revenues, until balance is achieved. Evidence suggests that the application of a rule of this type during the upswing prior to the last crisis would have substantially curbed the public spending permitted each year, allowing the generation of significant room for manoeuvre that would have limited the deterioration in public finances during the crisis. Finally, pressing ahead with the various pending reforms would raise the economy’s growth potential which – through its effects on employment and productivity – is one of the basic determinants of reductions in public debt. These reforms include, in the regulatory area, revision of regulations that hinder the market entry of new firms or that limit their growth; in the labour market, reforms to reduce the degree of duality and to improve the employment prospects for the long-term unemployed; and the need to increase the efficiency of the legal system and of the education system and to promote the accumulation of technological capital, among others. Accordingly, any delay in their implementation or, worse still, a hypothetical reversal of reforms already introduced since the start of the crisis, would significantly worsen the prospects for economic growth and would make the fiscal consolidation still needed more costly. Conclusions Let me conclude by recalling the challenges and risks for the economy as a whole raised by the current fiscal imbalance in Spain.
