An index number property such that the algebraic product of the price index comparing period j with period i and the price index comparing period k with period j is equal to the price index that compares period k directly with period i.

The property is also known as “transitivity”. When the axiomatic approach is used, a price index number may be required to satisfy the “circularity test”.
