The Demand for Intermediate Goods in an Input–Output Framework: a methodological note

This methodological note suggests the use of the maximum eigenvalues of the matrices of the direct input–output coefficients and of the coefficients of vertically integrated sectors as indicators of the aggregate intensity of the demand for intermediate goods. Such indicators have the desirable property of being independent from both relative prices and the composition of final demand and reflect therefore only the structural characteristics of the productive system.
