Shrinkflation

In economics, shrinkflation is the process of items shrinking in size or quantity, or even sometimes reformulating or reducing quality[1] while their prices remain the same or increase.[2][3] The word is a portmanteau of the words shrink and inflation. First usage of the term has been attributed to both Pippa Malmgren and Brian Domitrovic.[4]

Economic definition

Shrinkflation is a rise in the general price level of goods per unit of weight or volume, brought about by a reduction in the weight or size of the item sold. The price for one piece of the packaged product remains the same or could even be raised. This sometimes does not affect inflation measures such as the consumer price index or Retail Price Index, i.e. might not increase in the cost of a basket of retail goods and services, but many indicators of price levels and thus inflation are linked to units of volume or weight of products, so that shrinkflation also affects the statistically represented inflation figures.

Examples of shrinkflation
