Summary
By applying this relation all results in the two definition systems can be translated into each other. In this note we will analyze some relationships between increments in gross and net production.
It turns out that in case the external delivery structure changes {the non-diagonal coefficients of A), relative increments in gross and net production are identical.
A further result is that neither relative nor absolute increments in gross and net production are identical in case of changes in the internal delivery structure {the diagonal coefficients of A).
The third result is that relative increments in gross and net production are identical in case of a change in final demand.
Input-output analysis can be set up in gross or net terms. In the first case the internal deliveries of a sector are included in the table, in the other case they are neglected. These two different approaches give rise to two different leontief matrices: A and D.
Stone determined a relation between the two matrix multipliers (I-A)^-1 and (I-D)^-1
