First, the spending decisions of the older age cohorts are less likely to be easily stimulated by monetary policy. That is because such age groups tend to spend less of their incomes on consumer durables and housing. Second, as the population ages and the number of retirees climbs, the costs associated with Social Security, government pensions, and healthcare retirement benefits increase. This creates budgetary pressure and leads to a choice of raising revenue to fund these costs, cutting other government programs, or cutting benefits. Now if this all had been fully anticipated by retirees and near-retirees, then this would already be factored into their spending and saving decisions. But, I doubt that this has been the case. I suspect that many have been surprised by the swift change in economic circumstances as the housing boom went bust. I doubt that many fully anticipated the budget crunch and the prospect that their future retiree and healthcare benefits would likely be curbed or their taxes would have to rise in the future. When households begin to anticipate this, they reduce their assessment of their sustainable living standards. This downward reassessment then feeds back to current spending and saving decisions. A fourth reason why the recovery has been slower than expected may be that we overestimated the capacity for fiscal policy to continue to provide support to growth until a vigorous recovery was achieved.
There are, however, some institutional responses that will take place if the Bank is not able to return the exchange rate back to its initial range, as defined by the mandate, without contributing to inflation or a deflationary recession. I will come back to this issue later in my speech. 1  BIS Review 101/2000  The base drift problem If the inflation rate in Norway deviates from the inflation rate in the euro countries, the nominal exchange rate will need to adjust over time. However, some of you may object that stabilising the Norwegian inflation rate at the level aimed at by the euro countries may not be sufficient to stabilise the nominal exchange rate. The reason is that inflation in both Norway and the euro countries will be subject to stochastic shocks. This means that even if the expected inflation rates in Norway and the euro countries were the same, the actual inflation rates would deviate. Technically speaking, the relative price levels will be subject to base drift, and so will the nominal exchange rate. Professor Larry Ball has discussed this in a paper on Norwegian monetary policy. Keeping the relative price level constant would require that we target the price level and not the inflation rate. However, in the 1920s Norway experienced that a policy aimed at achieving a specific level for the purchasing power of money led to substantial macroeconomic instability.
