What is inflation?
Inflation is rising just about everywhere. Why is this and what can be done about it?
To get some basic concepts clear: inflation is a sustained rise in the general price level. Both the words ’sustained’ and ‘general price level’ are imprecise and in need of operationalisation. By general price level I mean a broad, representative index of consumer prices. That excludes the (headline) CPI in the UK because, like the other EU harmonised price indices, it excludes housing costs (that is, the rental cost of housing services or the imputed rental paid by owner occupiers). This makes the CPI/HICP indices unrepresentative, unless either the relative price of housing services and the goods and services included in the CPI/HICP remains constant or UK/EU citizens live in cardboard boxes provided free of charge by the Salvation Army. It may come to that, but not yet. The UK’s RPI and RPIX indices would be more representative.
I also exclude as unrepresentative various ‘core’ price indices, which exclude from the headline index such things as food, drink, energy and fuel. Among leading central banks, only the Fed has focused mainly on core inflation rather than on the headline index of consumer goods and services prices. Focusing on core inflation will be misleading unless either the relative price of core and non-core goods and services is expected to remain constant or Americans don’t eat , drink, drive cars and heat their houses or use air conditioning.
