mario.calc_v(V, X)

Calculate the v value added coefficients matrix.

\[v = V\,\operatorname{diag}(X)^{-1}\]

Parameters:

• V (pandas.DataFrame) – V value added transaction flows matrix.

• X (pandas.DataFrame) – X total production vector.

Returns:

v value added coefficients matrix.

Return type:

pandas.DataFrame

Notes

Inverse production is computed elementwise. A zero production entry has inverse zero, so the corresponding column is set to zero.
