mario.calc_pc(va, vc, wac, wcc)#

Calculate the SUT commodity price index pc.

\[p_c = w_{ac}^{\mathsf{T}}v_a^{\mathsf{T}}\mathbf{1} + w_{cc}^{\mathsf{T}}v_c^{\mathsf{T}}\mathbf{1}\]
Parameters:

  • va (pandas.DataFrame) – Direct value-added coefficients, with factor rows and activity columns. The columns must match the row index of wac.

  • vc (pandas.DataFrame) – Direct value-added coefficients, with factor rows and commodity columns. The columns must match the row index of wcc.

  • wac (pandas.DataFrame) – Leontief block with activity rows and commodity columns.

  • wcc (pandas.DataFrame) – Leontief block with commodity rows and commodity columns, matching the columns of wac.

Returns:

Price index, indexed by commodity nodes, with one column named price index.

Return type:

pandas.DataFrame

Notes

All value-added factor rows are summed before applying the transposed Leontief blocks. Both activity and commodity direct contributions are included.
