A measure of inflation used for inflation targeting in the UK. It does not include housing costs and is an index number relative to a base year (100).
How is the CPI calculated?
7000 households in the UK are surveyed using self-reported diaries of all purchases.
A price survey is undertaken once a month to collect data about price changes in the 700 most commonly used goods and services.
Weights are assigned to each item to reflect its proportion of income spent on it.
The price changes are multiplied by the weights given.
State 3 limitations of the CPI.
It does not include housing costs which make up a large proportion of household expenditure.
The list of 700 items changes only once a year so sudden changes in spending patterns are not reflected.
There are likely to be sampling errors from households.
What is the retail price index (RPI)?
A measure of inflation similar to CPI but does take into account interest payments on mortgages. Despite this, it is less accurate than CPI.
What are the 3 main causes of inflation?
Demand-pull - occurs when aggregate demand increases more quickly than aggregate supply.
Cost-push - occurs when aggregate supply decreases.
Growth of money supply - links to the source of inflation being the increase in money within the economy.
