Supply and Demand,Tax,Income,Profit and Proof of Goldbach’s Conjecture--Logic is the Basis of Correct Mathematical Measurement

This paper demonstrates that Marshall’s logic on the supply and demand curve is not rigorous enough,that Coase’s theorem is flawed,and that the“Okishio Theorem”and Sweezy s logic are inadequate through empirical proof.By the way,the Goldbach conjecture is proved through clever mathematical proof.It shows that beautiful curves and mathematical formulas cannot be separated from reality and logic,and correct logic can play a correct role in market theory.In this paper,the analysis of the actual supply and demand curve,as well as the concepts and models of tax,profit rate and income,has positive practical significance for economic depression and stagflation.

Prediction of network attack profit path based on NAPG model

The network attack profit graph(NAPG)model and the attack profit path predication algorithm are presented herein to cover the shortage of considerations in attacker’s subjective factors based on existing network attack path prediction methods.Firstly,the attack profit is introduced,with the attack profit matrix designed and the attack profit matrix generation algorithm given accordingly.Secondly,a path profit feasibility analysis algorithm is proposed to analyze the network feasibility of realizing profit of attack path.Finally,an opportunity profit path and an optimal profit path are introduced with the selection algorithm and the prediction algorithm designed for accurate prediction of the path.According to the experimental test,the network attack profit path predication algorithm is applicable for accurate prediction of the opportunity profit path and the optimal profit path.

Marxist Crisis Theory and the Rate of Profit in the U.S. Economy during 1975-2008

The cyclical fall in the rate of profit reveals the basic mechanism of the cyclical fluctuation of the economy.A new synthesis of the Marxist crisis theory necessitates calculating the rate of profit as well as considering factors such as capital-labor relations,realization of value,the organic composition of capital,and money and credit.Empirical studies suggest that the U.S.profit rate in real economy showed no signs of effective recovery during 195-2008.The shrinking profit share caused by growing employment of non-production workers turns out to be the major factor contributing to the cyclical fall in the rate of profit,which in turn may be traced to the reorganization of the production process before the 1990s and the growing flexibility of employment relations after the 1990s.With long-term stagnation of the rate of profit,a new,financialised model of accumulation that heavily depends on increasing liquidity in the economy took shape in the United States,making the U.S.economy more fragile.The current crisis is but a natural result of the intrinsic contradiction between the Fed’s efforts to encourage financialised accumulation and to maintain the dollar as a legitimate quasi international reserve currency.

Technical Change,Income Distribution,and Profitability:Marx's Law Revisited

Under the assumption of constant real wage,Okishio’s theorem shows that profit rates do not fall after any viable technical change.Research has indicated that if real wages rise after the introduction of technical change and then profit rates fall,then such fall in profit rates belongs to the realm of profit squeeze theory,which leads to the claim of the impossibility of a consistent theory of declining profit rate based on Marx’s insight.The present study proposes a two-channel framework to distinguish the mechanism of rising organic composition of capital from that of profit squeeze,and show that any viable capital-using and labor-saving technical change would lower the profit rate if the wage/profit ratio is unaffected in a multi-sector setting.
