What Catch Up Growth Under a Nominal GDP Level Target Looks Like
One more thing about Swedish monetary policy. I showed in a previous post that the Swedes seem to be effectively targeting the level of nominal GDP. A nice thing about level targeting is that it has "memory," that is monetary policy does not forget past deviations from its target and works in subsequent periods to make it up. Thus, it requires higher-than-normal catch-up growth if its targeted nominal variable it undershoots its target and vice versa. This catch-up growth can be seen for Sweden in the figure below which shows the year-on-year growth rates of nominal GDP: The Swedes appear to be aiming for just under a 5% nominal GDP growth. Starting in late 2008 and going into 2009, nominal spending collapses and contracts at about a 5% growth rate. To make up for this loss in nominal spending, the Riksbank nudges up nominal GDP growth up to almost 10% in subsequent quarters. Nominal GDP growth still remains elevated but now appears to be slo...
