A prelude to set the scene – borrowed from a commenter on Steven Keen’s ‘DebtDeflation’ blog
Q:
What would happen if engineers designed a bridge the way neoclassical economists have designed their model of the global economy?
A:
- The bridge would have foundations of dried shaving foam labelled “Assume the presence of reinforced concrete here”
- 10% of the structure would consist of lengths of cotton thread bearing sticky-taped notes saying “IOU one girder|stringer|cable|etc”
- the remaining 90% would consist of large areas of empty space that are annotated on the plans as “Will be filled by endogenous creation of decking” or “Section not required because structure is in equilibrium”
Yet, paradoxically, when the first sparrow attempted to perch on the bridge and caused it to crumble into dust, its collapse would cause a magnitude 10.2 earthquake and devastate everything within a 1000km radius.
Recently I have been thinking about our national and global society and how random its modern successes and failures appear to be – how this seems a poor way to build on the huge back-history of momentous sacrifices, advances and “never again!” moments that have come before. By now, surely, with our technologies and allegedly clear understanding of how the systems of our society operate, we should be free to plot our course and advance steadily on autopilot while focussing on improving ourselves in so many necessary ways. Unfortunately, our economy and economic policy have recently struck me as being disturbingly like ancient astronomers using fanciful and utterly incorrect contraptions in an attempt to explain and predict the heavens. Once I started poking around I noticed the very same parallel being drawn in these articles: Economists are the forgotten guilty men and Now is the time for a revolution in economic thought.
How are we ever going to be able to live peaceful lives in a stable, safe world when every context is governed by economic “wise men” performing digital auguries, based on logic flawed at its most basic levels, explaining everything with scapegoat-of-best-fit and constantly mis-steering us?
As I started this entry I ran into the blog of Steven Keen whose book “Debunking Economics” was (is?) sold by a previous workplace of mine. What I have read of his logic and discussions always makes a huge amount of sense to me. He rails against the most basic tenets of our economics – well at least the basic tenets of the neo-classical economics that defines, “explains” and “steers” our world today.
Neo-classical economics appears to use as a basis some things that appear rather obviously naive. For example: How can anyone base a massively interconnected system’s smooth running around the assumption that every actor in it has full knowledge of the state of the whole system? In this form of economics, to the best of my meagre and un-nuanced understanding, this is the case. So for the economy to run effectively, and balance itself properly, it relies on every purchaser knowing about every product that can meet their needs … and every quality of those products … and of their producers … and how the prices vary across localities … even how they vary over time … As if. Next time you need some pumpkin make sure you bone up on the international market and figure in shipping prices before you decide where to buy it. How can a human consider a fraction of this information in every purchase that we make – let alone obtain the information. We’re all victims of geographic, vendor or supplier lock-in for almost everything we ever buy.
Another obvious naivete is the tenet that all parties in the system behave rationally – even mechanically or slavishly – following the logic and actions that an economist with full knowledge of the system would. However … no-one ever does. People and corporations are more subject to influences on their psychology than to logic in most cases. A crash? I’d better jump. Wrong – the market already crashed! It’s too late – now you’ve lost almost all of your money (“crystallised your loses” as they term it). I can think of a good example of where traditional economics breaks down: in the fear that corporations show when faced with a low-price product – they won’t buy it – if it doesn’t cost them millions it must be flawed in some way. However neo-classical economic axioms would dictate that a consumer should always buy the cheaper of two equally appropriate products… Enter psychology and the bizarre effects that it has on buying patterns. Another current example is the way that the banks, the corporations and the people are all holding their breath (and their money), resisting the economic and political pressures being applied and waiting for a clear sign to jump. In neo-classical economics there is no pause, no holding of breath, no hesitation or second guessing – it anticipates we all have full knowledge of the situation and of the outcomes of our actions, that we will act and act immediately.
Looking at our current situation it is plain and obvious that the best thing we can do is to continue as normal, spending, lending and employing – however people are saving (I can’t blame them), banks are denying refinancing to major companies (even those with massive assets), and companies are sacking employees (despite having significant profit margins). No-one in the whole network is listening to the pressures applied by the government or the economists.
Yet despite all this we trust the concepts built on these basic assumptions – but the assumptions are flawed. And we build models on the concepts – and the models are guesstimates and oversimplifications at best. And we rationalise the past based on these assumptions – but in the flurry of a national or global economy nothing is as simple as they paint it. And we even make momentous commercial, national and global decisions based on these assumptions – and eventually something snaps and everything grinds to a shuddering halt…
Despite being trusted to explain and steer our economies, the ’science’ of economics seems to have been completely incapable of rectifying its own market failures. Japan, the intellectual and technological giant, has spent years trying to pull itself out of its financial hole, however international analysts have looked at the results so far and questioned whether the neo-classical measures that were taken have done more harm than good. Massive spending and incentives on the part of the government, intended to resurrect the economy, actually encouraged a bond bubble that burst and caused its own crisis in the midst of the one they were trying to climb out of.
How can an economics of this kind be considered a science, or be trusted as one would trust a true science, when its models (laws) cannot account for the past, prevent disasters or even rectify itself? That’s what a science is! We look at what has gone before, define patterns, derive rules, use those rules to explain how and why those things happened, and go as far as applying those rules in making predictions, which we then use to validate our model, and then use those rules to manipulate events. But in the case of economics this is a farce – its numerous models are divergent, no prediction holds and models are constantly modified to better reflect the recent past with no regard for long term accuracy. Anyone who occasionally listens to financial news, or is vaguely following the current crisis, can see that economics is more about greed/self-interest, fear/paranoia and desperation than laws – it’s more like financial psychology than a science, with an equally egregious history, hand-wavey present, and always brimming with mountains of retrospective wisdom.
How can anyone look at a national or global economy and not have chaos theory come to mind? Billions of seemingly inconsequential actions over time, millions of conflicting influences on the actions, inertia inexplicably building up where people can’t see it and then suddenly a tipping point or an elastic limit is reached and the whole system unwinds catastrophically into a smoking heap.
Economic forecasting and planning using the established models appears to be less reliable than the oft slighted meteorology.
How can economists and governments watch our debt-to-GDP levels spiking (as they have done numerous times before) and allow or encourage it, leading us to the inevitable bust (as it has numerous times before)?
An insider critique of our economic tradition has been written and it seems quite damning, pronouncing this crisis as a market failure of the economics profession itself. I find it amusing to see the report quote economics writers (traditional neo-classical economists) as having noted “… the possibility of an increase of ‘systemic risk.’ But … this aspect should not be the concern of the banks…because it is the governments’ responsibility to provide costless insurance against a system-wide crash…”
So, as far as those economists were concerned, things should be ok and yeah sure our system and actions may lead to bigger and bigger risks building up to threaten the whole economic system, but it’s all ok because the tax payer will be there to wear the outcome and cost of our speculations and shortcomings…
Anyway – enough prattling.
