Definition

Leontief Matrix. The Leontief “A” matrix is a direct requirements table calculated from an industry-by-industry transactions table.

The “I - A” matrix (where I is an identity matrix with ones in the diagonal cells and zeroes in other cells) can be inverted to calculate the inverse ((I - A)-1 ) or total requirements table.

The elements of the inverse enable one to estimate both the direct and indirect impacts of a change in final uses.[1]
