Pre -multiplying it with a'AB we obtain a vector of flows from the consumption goods business sector: a'ABC = vector of imports, ind. and direct taxes, saving, distributed profits, wages and salaries. Post-multiplying this with B we get a further round, and so on. In the end we have to add up the two series, outflows from business firms and outflows from households. This yields the total offsets against the primary expenditure. The sum of the series can be written a. A r (BC) n vector of flows from business O a'A^T (BC) B vector of flows from households The convergence requires that the coefficients in the matrices A,B,C are all smaller than unity.
