The physiocrats were also correct in their belief that land can provide value, in its role in capturing the sun's rays. Where Smith, Marx, Ricardo, Sraffa etc were correct was in their belief that value is an inherent quantity, embodied in the goods and services in the economy. However, as was found a

ply balances to equal the above demand, where supply costs of commodities are calculated by aggregating costs of inputs on a cost plus basis, as per Sraffa, (un-reconstituted) von Neumann, market-microstructure and post-Keynesian analyses, but done on a dynamic equilibrium basis. At this level, price

The research on liquidity suggests two implications for finance that are both quite profound, the first area relates to the pricing models based on Black-Scholes, the second to the pricing of shares under the CAPM. Almost all modern option pricing theory is based on the Black-Scholes model, or other closely-

sible), then it may be that measurement of liquidity might be able to give good timely measures for current volatility that can be used directly in Black-Scholes models; rather than the current practice of imputing from historical volatility. A second significant area of interest for the application of liqui

n economics had been systematically disproved by neoclassical economics. More reading of economics quickly proved the second assumption to be false, Sraffa was the victor of the Cambridge capital controversies. The labour theory of value is indeed nonsense. However the concept of absolute value is not

andom walk process has been removed from it's many body background, and individual prices are treated as moving randomly isolated by themselves. But Black-Scholes is simply the diffusion equation, and things don't diffuse with random jumps in a vacuum. The random movements of dust particles undergoing Brownia

that this chaotic motion is noticeable in objects as large as planets. This is not simply the chaos of quantum effects or the stochasticity found in Black-Scholes. This is 'deterministic chaos' or usually 'chaos theory'. The chaos is present even in problems that can be described in exact mathematics and are

clear that the models were modelling the economics of the classical economists; the economics of Smith, Ricardo, Marx, von Neumann (unmodified) and Sraffa. With hindsight this turned out to be a consequence of the second of the two original models I had proposed in 2006. In this model wealth is implic

ists working in finance have not only accepted this, but they have built more and more baroque models on these flimsy foundations. The trouble with Black-Scholes is that it works very well, except when it doesn't. This basic flaw has been pointed out from Mandlebrot onwards, to date with no notice taken. Thi
