pymrio.Extension.calc_system

Extension.calc_system(x, Y, Y_agg=None, L=None, G=None, population=None)

Calculate the missing part of the extension plus accounts.

This method allows to specify an aggregated Y_agg for the account calculation (see Y_agg below). However, the full Y needs to be specified for the calculation of F_Y or S_Y.

Calculates:

  • for each sector and country:

    S, S_Y (if F_Y available), M, M_down, D_cba,

  • for each region:

    D_cba_reg, D_pba_reg, D_imp_reg, D_exp_reg,

  • for each region (if population vector is given):

    D_cba_cap, D_pba_cap, D_imp_cap, D_exp_cap

Notes

Only attributes which are not None are recalculated (for D_* this is checked for each group (reg, cap, and w/o appendix)).

Parameters

  • x (pandas.DataFrame or numpy.array) – Industry output column vector

  • Y (pandas.DataFrame or numpy.arry) – Full final demand array

  • Y_agg (pandas.DataFrame or np.array, optional) – The final demand aggregated (one category per country). Can be used to restrict the calculation of CBA of a specific category (e.g. households). Default: y is aggregated over all categories

  • L (pandas.DataFrame or numpy.array, optional) – Leontief input output table L. If this is not given, the method recalculates M based on D_cba (must be present in the extension).

  • G (pandas.DataFrame or numpy.array, optional) – Ghosh input output table G. If this is not given, M_down is not calculated.

  • population (pandas.DataFrame or np.array, optional) – Row vector with population per region
