Inferior good

An inferior good occurs when an increase in income causes a fall in demand. An inferior good has a negative income elasticity of demand. (YED) Inferior goods are characterised by low quality – and are goods with better alternatives.

For example, if average incomes rise 10%, and demand for holidays in Blackpool falls 2%. The YED of Blackpool holidays is -0.2. A holiday in Blackpool is an inferior good. When income rises, people can afford to forego the cheap alternative and buy the higher quality good instead. In this case, it is holidays abroad to Lanzarote.

For example, a person on low income may buy cheap gruel. But, when his income rises, he will afford better quality foods, such as fine bread and meat. Therefore, he stops buying gruel.
