weight x price
why is the CPI not a good measure of inflation (3 points)
only shows prices in cities which is not the true cost of living
doesnt reflect consumer preferences/substitutions
doesnt account for changes in equality of goods so price tends to be overstated
what is a headline measure of inflation
the CPI is a headline measure of inflation, it is a broad measure of cost change in new purchases made by salary/wage earners
what are the 2 factors effecting headline measures
- price of agricultural commodities change each season (price falls when supply is up but rise in shortage or out of season)
- Macroeconomic events - fall in interest rates mean household spending on mortgages have fallen
what is an underlying measure of inflation and why is it better than headline
gives a more accurate picture of inlation and removes the above influences
how do you calculate underlying measures:
- trimmed mean
- weighted mean
- trimmed mean - all prices are arranged big to small and the top/bottom 15% are trimmed of
- weighted median - median of inflatino rate in CPI basket
what is demand pull inflation
too much money chasing too few goods - high demand caused by expenditure levels pulling up prices
what are 3 things that idnicate high demand (demand pull)
- high spending on construction/consumer durables
- excess money supply (growth rate money > growth rate output)
- excess labour demand (forces up wages = spending = = prices)
what is cost push inflation
rising production cost passed onto consumers through high price
what are 5 events that increase output price
- wages rise faster than worker productivity
- improts prices rises due to decreases currency
- rising energy price
- rising oil/petrol price
- natural disasters
