GDP growth and
resource utilisation
Saltsjöbaden
6 October 2011
First Deputy Governor
Svante Öberg
Summary
Resource utilisation can be measured in
several different ways, among others as
actual GDP in relation to potential GDP
(GDP gap)
 The financial crisis has lowered the
growth rate of potential GDP
 Resource utilisation is thus largely
normal, even though GDP is only slightly
higher than before the crisis


2. The significance of resource
utilisation for monetary policy



The target for monetary policy is to
hold CPI inflation at 2 per cent
The Riksbank also takes into account
high GDP, high employment and low
unemployment
Resource utilisation is also an
indicator of future inflation

6. Need for continued analyses




What determines the development of
productivity and potential GDP in
normal business cycles and in deep
recessions?
Particularly TFP
Combine the production function
approach and economic short-term
statistics
Use micro data
