Headline Inflation
Slide1.jpeg

Headline inflation is a measure of the changes in prices that includes irregularities and anomolies within the economy. This means that unusual or seasonal fluctuations in prices are included in this figure. An example of this occured during the COVID-19 pandemic, when childcare payments was covered by the government, and therefore free for society. This irregularity in the economy would be included from headline inflation calculations.  This type gives a more accurate indicator of price changes and is the measure used most often.

Underlying inflation calculates the changes in average prices of consumers’ purchases without including anolomies or irregularieties in economies. Using the same example, dwhen childcare payments were temporalily free, this fluctuation in price was excluded for the final figure. It can be found using either the 'trimmed mean' or 'weighted median' methods, used to remove the top and bottom 15% of inflation figures in order to attain an average. For this reason, this type of inflation produces as a very broad measure that is prone to short term fluctuations as well as also demonstrate the price changes of different types of goods which can indicate economic performance.

As shown by the graph from the Reserver Bank of Australia, the different statistics produced by both types of inflation show many similarities, yet in certain instances, the values produced are very different. This could be due to seasonal influences, such as cyclones destorying crops or price changes from the COVID-19 pandemic that have shocked the economy in particular years. The effects of these shocks would not be included in underlying inflation, yet they would be included in the headline inflation figure, thus producing different results.
