Why the economic crash of 2008 will not be the last such financial crash.

As an economist I know of several explanations of why economies experience sudden and unexpected down turns, the usual explanation is the bursting of a credit bubble as happened in 2008. These downturns or crashes are always claimed by our political leaders to be unpredictable events, once in a life time happenings, even an ‘act of God’. Even when as in 2008 when the crash was caused by both human folly and greed. This misunderstanding is only possible because politicians have never understood the economics associated with John Maynard Keynes. He stated that economies are inherently unstable and these sudden and unexpected collapses in economic activity are part of of natural economic cycle. Unfortunately politicians act as if the good times will continue forever, a dangerous self delusion.

Although an economist by education, I am a philosopher by interest. Unlike Keynes I want use the techniques employed by the Greek philosopher Plato to explain the instability of the economy. He used myth to explain those aspects of reality that were not easily given to rational explanation, myth could make understandable, what reason could not easily explain. Perhaps the myth of the cave is the best known. A myth he uses to explain the ignorance of mankind as to the true nature of reality. He says imagine mankind as a group of individuals chained up in a cave. These chains prevent them moving and force them to look in one way only forwards.. In front of these men is a wall behind which is a fire. Now behind that wall images of things are passed backwards and forwards, so all the chained men see is a series shadows, which they take to be reality. Mankind for Plato could only see the world of appearances, which obscured the true nature of reality. However as I’m a 21st century economist who does not believe in myth, I will use metaphor as a substitute for myth.

The economy can be seen as a jigsaw puzzle in which the pieces seem to fit together to form a picture,. It’s seems to be composed of a series of interlocking pieces that fit together to form an integrated whole. However closer inspection of the puzzle reveals that the pieces do not fit easily together. There are gaps between the pieces they don’t easily fit together. Now if the tray on which the pieces are resting is moved, the puzzle immediately begins to lose shape and the picture eventually disappears from sight. The economy can be seen as a badly formed jigsaw puzzle that is likely to falling apart at any disturbance. Politicians ignorant of economics constantly make foolish decisions, that disturb and disrupt the economic policy. Occasionally they make disastrous decisions that cause the economic puzzle to fall apart,

There have been in our recent history a series of such foolish policy making from our political leaders. The most common fallacious policy is to promote speculative boom in either the property or stock markets as the main driver of economic activity. It is the fools gold of a policy. If economic growth is dependent on a constant inflation in house and property prices, there will be a time when market confidence fails and asset prices collapse and with it the economy. Unfortunately this simple understanding of the economy is beyond the political classes. Politicians seem predisposed to believe that everything in the garden is rosy and nothing bad will occur. A recognition of the fragility on which economic well being is based is too disturbing and unsettling to be accepted as a truth by our blindly optimist politicians.

The jigsaw metaphor can be used to explain how policies should be made to fix an economy, once a downturn has occurred. The broken puzzle can be put together through decisive political action and the economy rebuilt. There might have to be some reshaping of the pieces to make them fit together better, so making the economy more resilient to future shocks. Obviously the one piece that needs to be reshaped is the property and financial markets. Action needs to be taken to limit the activity of speculators in each. This action is a system credit controls and taxation that chokes off any foolish speculative activities. Unfortunately the politicians seem to believe that remaking the economy is an impossible task. What they prefer is the maladroit tinkering that is called Neo-Liberalism or leaving the market to fix itself. This is akin to asking these malformed pieces that remake up the economic puzzle in their own image. As a consequence the speculative economy that caused the collapse of 2008, has been rebuilt by the dominant players in the market, bankers and financiers with minimal interference from the government.

I must confess to one failing which is typical of all economists, I find it much easier to explain why economies go wrong than why they go right. My jigsaw metaphor cannot explain why the economy is subject to exuberant and unexpected periods of rapid economic growth. Perhaps if economists such as I could explain this economic fact, the economy would be in a better position than it is now.
