Chapter 32 Inflation
What do we call the verb to “blow up a balloon” to “inflate” So what is inflation in the economy? → Brainstorm a definition Inflation = a general and persistent rise in prices. It is shown as a % Deflation = a decrease in the general price level of goods and services. May also be used to refer to a period where aggregate demand (total demand in an economy) is falling. This should not be confused with disinflation, a slow-down in the inflation rate (i.e. when inflation declines to lower levels). So when inflation slows from 3% p.a. to 2% p.a. this is disinflation not deflation, as prices still increased by 2%
How is inflation measured? (in the UK) Brainstorm Consumer Price Index (CPI) = Every month the government records the prices of about 600 G & S purchased by over 7,000 families.
