1.Derivation of the Angel curve for an inferior good
Engels curve defines the varied nature of expenditure and income of households. It shows how with an increase in income of a household, its expenditure increase but not with the same proportion as to income.
In case of inferior good this principle hold true as with an increase in income their demand falls because people prefer to move form inferior to nornal goods. And hence their is least expenditure on them after an increase in income.
