Definition

Proportionality Principle. One of the three fundamental principles underlying the I-O accounts. Under this principle, all inputs consumed by an I-O industry are a linear function of the level of output - that is, the inputs consumed vary in direct proportion to output and there are no economies of scale.

The other two principles are Consistency Principle and Homogeneity Principle.[1]
