- Classical and neo classical economics
Classical economics aimed to understand pricing and supply of goods through analysing the costs of production (land, wages, tax, materials, etc…) Neo-classical economics turned the viewpoint round and tried to analyse price and supply through the (marginal) preferences of aggregated consumers. The customer is king in retail and neo-classical economics.
2. Some seductive simplifications
The great thing about classical and neo-classical economics is a reductionist approach to economic equations. Both make the economy appear simple enough for a clever person to work out the mathematics with a pencil and a slide rule.
Economics was itself seduced by Newton. The idea of classical physics and mechanistic equations held a high place in the mind of the 19th century. And indeed, linear mechanistic equations are a hallmark of neo-classical economics (most famously the demand curve).
The paradigm holds that in aggregate people and firms can be seen as Rational, to maximise their utility/profit rationally and to be possessed of perfect information (Weintraub). Any departure from this leads to the excruciating detail of micro-economics and unpredictable non-linearity. Which is not comforting.
The paradigm also has a tendency to depict closed, linear systems. Firms are treated as bounded, as are national economies. But perhaps the most curious feature of this, is that it leaves out any role for the creation of debt. There is no account for purchasing power created by banks.
Instead this explained away by a form of double entry book-keeping type thinking where the creation of debt in one place always balances with the creation of credit in another. Leaving a nice neat zero in the maths (though often a huge hole in the finances). (cf. Keen)
3. Non-sensical implications
The difficult journey for neo-classical economics was that it started as a new an insurgent way of explaining the value and movement of goods. But in doing so through the idea of consumer preference found itself talking not about the value of goods but the motivations of people. Indeed it might be said to have moved from reductionist economics to a one-dimensional psychology.
The attempt to explain consumer behaviour by price, rather than movement of goods by price is almost an inevitable over-reach driven by the demands of the theory.
Further the combination of deifying the consumer’s taste whilst sweeping debt under the rug produces a very curious approach to assets. Wherein they find that price is value, and that value is, based on the premises, ultimately rational.
However, the rational price today is not the rational price tomorrow. This plain fact is difficult for the theoretical framework because a la demand curves, all markets clear (number of sellers and buyers match) and that this creates an equilibrium of supply and demand.
As some have noted, that the fact that an equilibrium price may exist for a market does not necessarily mean that consumers and producers will together find that happy balance, but rather, might oscillate around a point of balanced supply and demand ad infinitum.
4. Making neo-classical economics make sense
Clearly, it would be of great advantage to have a clear picture of the movement of goods within a society. The approach of neo-classical economists is often to say that their predictions are wrong not because their model is imperfect but that reality is imperfect. Or more specifically, the national legal/policy framework is causing a distortion.
Taking this view to heart, the first step would be to end the creation of capital by any means other than profit.
If finance was to exist it would be rationally allocated by a system with the capacity to predict and secure payment of all debts.
Further if all the marginal preferences of consumers were held on a database (as is the aim of advertising data) then a balance between forward production and forward consumption could be planned for. This system would be in possession of as near perfect information as possible and as per the theory, open to all consumers. This would allow the satisfaction of consumer preference without the need currency.
And then voila, you might have an economy that matched the neo-classical picture. It would be a “de-centrally planned economy”. Somewhat Hegelian.
5. Rationality
Many of the assumptions in neo-classical economics, and the other enlightenment era ideas are founded on the notion of rationality. However, once again, rather than taking a nuanced view proceeding from the ideas of logic, rationality in economics is taken to be somewhat generalisable, largely from the incentive of price.
In classical economics the concern is for the most part with rational production and consumption (Land, food, ships). The move to consumer preference, and to a wider range of consumption leads us into taste. If one consumer’s notional utility from purchase of a good is greater than another’s, then the least we can say is that their rationalities have produced a different value.
If we go into non-rational consumption, culturally mediated value in symbols (£40 to 20p Nylon shirt with a logo on) we rapidly stray from a behaviour that can be explained, deduced or extrapolated from our understanding of the movement of basic goods. We are into an eco-anthro-pyschonomics.
There is the idea that computers might make us more rational. But the next generation of artificial intelligence, built of neural nets, would appear as changeable and flighty as its creators, on whom the pattern of information processing is modelled. The mathematics of intelligence may be in itself and by necessity an oscillation between rational and “exploratory” or “experimental”.
6. A Scaffold to Absurdity
Like many of our institutions, the pressure to revise in the face of new possibilities is existential. If we continue to look out from and build within these old frames of reference, we will be vulnerable not simply to our own mistakes but to the predation of others with better understanding.
The maths does not have to be done on paper, the data does not have to be taken in aggregate, behaviour does not have to be understood through one dimensional incentives, the system does not have to be seen as closed. And of course, if we direct our entire focus of understanding resource allocation through a paradigm created for the production and consumption of physical goods the planet will strain to the point where billions die.
Neo-classical economics is more than a century old. It grew from a discipline known as political economy. In the recombinant analytics of culture it is probably time to reintegrate this elegantly simple strain of thought into a fuller picture that drives both understanding and allocation of resources in the post-Kantian world.
