It is nevertheless relevant to raise the question as to whether monetary policy in general has been too expansionary. I would, however, point out that monetary policy must be evaluated in relation to the decision-making basis that existed at the time the decisions were made. Given the decision-making basis prevailing in 1999, it seemed likely that the Norwegian economy would experience a growth pause and that price and cost inflation would fall. Moreover, the international financial market was fragile as a result of the many financial crises the previous year. As new information gradually pointed to higher growth in Norway and internationally, coupled with the prospect of higher-than-expected price and cost inflation, we raised the interest rate. It may be that the combination of the decline in interest rates in 1999 and the brighter international growth outlook, partly reflected in higher oil prices, had an impact on expectations formation that we underestimated. Today, the krone exchange rate is approximately in the initial range, while inflation is higher than the level aimed at by the ECB. However, the interest rate is oriented towards bringing price and cost inflation down towards this level. If price and cost inflation remains too high, this will translate into a weak and unstable krone exchange rate sooner or later. 12  BIS Review 7/2001  Conclusion In the conduct of monetary policy we have two objectives. First, we have a long-term perspective where building confidence and credibility is important for ensuring nominal stability.
In its conduct of monetary policy, Norges Bank focuses on the fundamental preconditions for achieving exchange rate stability against the euro. First, price and cost inflation must be brought down towards the corresponding aim for inflation for the European Central Bank (ECB). At the same time, monetary policy must not in itself contribute to deflationary recessions as this could undermine confidence in the krone. There are few significant differences between Norway's actual response pattern and that of countries with explicit inflation targets. Price and cost inflation must be steered towards that aimed at by the ECB. However, in Norway fiscal policy has traditionally had an important role in stabilisation policy. This has reduced the burden on monetary policy. In addition, the Norwegian wage determination system has probably contributed in periods to dampening the impact of shocks hitting the economy. Monetary policy influences price and cost inflation with a time lag of perhaps one to three years. In consequence, projections for price and cost inflation with a horizon of a couple of years play an important part in the setting of interest rates. From the time interest rate decisions are taken until the interest rate has an impact on prices and costs, various types of disturbance occur which influence price and cost inflation. Thus it is not possible to maintain full control over developments in prices and costs. Actual price and cost developments normally deviate somewhat from earlier projections.
