And the reason I am doing so now is that it may be a good starting point for distinguishing what monetary policy may achieve in the short and long run. We can note already that the policy areas I recently mentioned concern politics in a broad sense and not monetary policy. It is thus not monetary policy that can affect these most fundamental conditions for long-term growth. One illustration of monetary policy’s limited potential to affect employment in the long term is the disparate regional developments in one and the same country. In Sweden, for instance, there are large regional differences in employment levels, despite monetary policy being the same for all regions. These differences appear to be lasting, which might indicate that they are due to underlying, structural factors that are beyond the control of monetary policy. However, monetary policy can affect the conditions for long-term growth on one very essential point, namely by keeping inflation close to the target and inflation expectations anchored around the target. If inflation deviates from the target the Riksbank’s aim is normally to bring it back on target within a couple of years. Depending on how large the deviation is and its cause, the time horizon may be extended. This flexibility makes it possible for the Riksbank to take into account developments in the real economy in its monetary policy considerations. In the short term, monetary policy can contribute to reducing the fluctuations in production and employment that arise during an economic cycle.
Barbro Wickman-Parak: What can monetary policy achieve? Speech by Ms Barbro Wickman-Parak, Deputy Governor of the Sveriges Riksbank, at a meeting, Karlstad, 27 March 2009. *  *  *  Economic policy can be divided up into two areas: fiscal policy and monetary policy. In Sweden and all other countries with independent central banks, there is as we all know a distinct difference between these two policy areas. The Government is responsible for fiscal policy and the central bank for monetary policy. The central bank is not allowed to receive instructions from any other party when carrying out its monetary policy tasks – it is to conduct its monetary policy in an independent manner. So what is the range of the policy area delegated to an independent central bank; that is, what can we expect a central bank to be able to achieve? This question is the theme of my speech today. Economic policy ultimately concerns creating the best possible conditions for long-term growth and thereby a high level of welfare for the population. The given limit for growth is set by developments in the labour force and in productivity. To attain long-term growth the policies must be aimed at, for instance, educating the labour force, creating an incentive structure that stimulates people to work, creating a good innovation climate that promotes technological developments and so on. This is all common knowledge, but may be worth saying sometimes.
