The Main Ideas:
Definition of Income
The maximum amount that can be consumed during the period while still expecting to be as well off at the end of the period as at the beginning of the period (Hicks 1946)

Instability of the accounting measuring unit is due to the effects of inflation or deflation.
General purchasing power adjustments
Current purchasing power accounting (CPPA)
Also called general purchasing power accounting; general price level accounting; constant dollar accounting
