Keynes' principle of effective demand based on the Keynesian multiplier effect is mathematically wrong. The equilibrium solution of an initial state: 5=Y*=2/(1 - 3/5(=MPC)), which is correct. ΔG=investment fund. An incremental state: 5+ΔG = Y** = (2+ΔG) / (1 - 3/5). The multiplier effect formula: ΔG = ΔG/(1 -3/5). 2=5, which is incorrect. 5+ΔG=Y**= (2+ΔG) /(1-3/(5+ΔG)), which is correct.
Although Leontief's IO (input output) table is very useful, all the existing analytical results of the IO analysis for economies are mathematically wrong. The reason is that the correct solution for both the open model production equation and the price model equation should be joined to the single equation Y(=GDP)=H・V(=GVA), which is an Affine transformation.
Walras' general equilibrium (Walrasian equilibrium) in economies does not exist in capitalist societies from the existence of wisdom variables (desires for efficiency and extension) and the indeterminate relationship (Δfixed cost =ΔCm ,finite value≠0) between a labor volume and its wages. GVA in the past can be uniquely determined depending on the fact of GVA's generation, while GVA in the future cannot be determined as long as decision making will variables (e.g. dismissal, innovation and consumer confidence etc. ) are not determined.
Keynes' involuntary unemployment is caused by the conflict between ΔπO (incremental profit and loss) and the other items (wages in the case of GVA) in the equation ΔX =ΔDXm+ ΔCm (finite value≠0)+ ΔG + ΔπO in a given incremental decrease of ΔX (GVA=GDP) .
The logic of J.A. Shumpeter's innovation theory is mathematically shown.
The CVP analysis or the break-even analysis is easily possible in business accounting under standard costing or absorption costing.
Structural analysis for the Minami Bisan-Seto Bridge (suspension bridge) is introduced.
