LDU-factorization of Miyazawa income multipliers in multiregional systems
A new triple LDU-factorization (L represents a lower-triangular block matrix, D represents the diagonal block matrix and U represents an upper-triangular block matrix) of the Leontief inverse is based on the Schur block-inversion of matrices. This factorization is applied to the decomposition of Miyazawa-type multipliers of income formation within the multiregional system and to the further elaboration in the extended demo-economic multiregional input-output analysis.
