What is inflation Sustained increase in the price level Measured in the UK using CPI (Consumer Price Index) Rate of inflation (%) = percentage change in the CPI over the previous 12 months = annual inflation Inflation describes a general movement upwards Governments current target = 2.0% (+/- 1%) = very difficult to hit central target 9. UK Inflation 2000-2013 3 key points about the CPI since 2007? 10.

Weighted Price Indexes Price Index: change from 100 to 106 = +6% 25% of household expenditure on food So 106 X 25 = 2650 Add them together, then divide by total of weights (100) New price index = 106.6 14. Weighted Price Indexes Recalculate the price index if: 1) If the index of food prices grows to 120 2) Cheaper imports caused the index of clothing prices to fall to 95 3) If the weighting of transport increases to eighteen per cent and that for miscellaneous items falls by four per cent 15.

Population Groups vary CPI = average household But different groups have different spending and therefore different inflation EG weighting for cars and tobacco will be irrelevant for non-smokers and those without a car No house prices Mortgage payments represent high proportion of spending of younger house buyers Older house owners have paid off mortgages Over-estimate inflation Price rises may hide real improvements in quality Prices of many cars and electrical goods have fallen over the last 30 years, but innovations have made them significantly better 17. Objectives Revise key inflation terms Understand the CPI and weighted price indexes Analyse the limitations of the CPI Understand the causes of inflation 18. Cost-push inflation Rise in costs of imported raw materials eg wheat and oil Rising labour costs Higher indirect taxes. VAT up from 17.5% to 20% Wage-price spirals 19. Draw it! Cost push inflation AD1 AS1 AS2 0 General price level P1 Y1 Real GDP Y2 P2 20. Demand-pull inflation Little spare capacity in the economy Increase in AD leads only to an increase in prices AD increases when one or more of its components increases. E.G increased spending due to reduced income tax 21. Draw it! Demand pull inflation 22.
