Using the latest in IP address geo-detection and profiling technology we’re delighted to bring you your personalized horoscope:
You have a great need for other people to like and admire you. You have a tendency to be critical of yourself. You have a great deal of unused capacity which you have not turned to your advantage. While you have some personality weaknesses you are generally able to compensate for them. Your sexual adjustment has presented problems for you. Disciplined and self-controlled on the outside, you tend to be worrisome and insecure on the inside. At times you have serious doubts as to whether you have made the right decision or done the right thing. You prefer a certain amount of change and variety and become dissatisfied when hemmed in by restrictions and limitations. You pride yourself as an independent thinker and do not accept others’ statements without satisfactory proof. You have found it unwise to be too frank in revealing yourself to others. At times you are extroverted, affable, sociable, while at other times you are introverted, wary, and reserved. Some of your aspirations tend to be pretty unrealistic. Security is one of your major goals in life.

Cargo Cults
In the Second World War many remote Pacific islands found themselves occupied by warring forces. This often led to an unexpected windfall for the primitive islanders as the troops were supplied from the air with unimaginable luxuries like corned beef, custard powder and anti-aircraft guns. When the war ended and the troops went home the planes stopped coming so, naturally, the islanders hatched a cunning plan to make them come back again.
They created the rudiments of the apparatus that the ground crew had used – paddles to welcome the aircraft, fake headsets for the radio operator, fake landing lights – and engaged in the same strange ritual ceremonies, behaviour generally known as a cargo cult. Yet no matter how they adjusted the ceremony they couldn’t get it quite right and the planes never came back. It would be crass simplicity to suggest that the same kind of magical thinking pervades the world of investment. Only it does, of course.

Bacteria, Boids and Market Instability

Here’s some weekend reading in advance. Consider throwing away economic models based on the misconception that people behave rationally and start anew with the premise that we are like mindless bacteria. – Ilene

The Gaps Between People
Old-time economics saw investors as rational individuals, all behaving autonomously in a logical fashion, rather like Mr. Spock umbilically attached to Deep Thought. Today not even economists really believe that this is how people actually operate, but figuring out something better is a not insignificant task. Psychologists, however, have long known that what happens in the gaps between people is as important as what happens in the gaps between their ears – so is there something going on in the interactions between investors, which causes market instability?
One possible answer comes from the study of bacteria. Just as we might have suspected all along, stockmarket investor behaviour can be modelled by examining the way a bunch of brainless, single celled and barely animate creatures interested only in food and reproduction disport themselves on a Petri plate. Sometimes analogies are just too sweet.
Investing Earthquakes
The critical thing about any economic model is that it arrives at results that look like what we actually see in markets. Mostly the jargon fixated commentators who dominate the media are happy to talk in terms of business cycles when, in reality, the only cycles seen in most investing circles are the ones used by the boys and girls delivering lunchboxes. What we actually get, if we look at stockmarkets and stock prices, is something that looks like the readout we see from a seismograph when an earthquake occurs.
If we start by making a few assumptions about what investors actually do in real life – like, for instance, that they don’t behave rationally and that they tend to copy successful behaviour from people they’re closely connected to – we can rapidly create a model that produces outputs that look very different from those generated by models of people who behave independently and rationally. In fact the output of these models looks a lot like the readout we see from a seismograph when an earthquake occurs.
So it seems that the interactions between investors and how these interactions affect their willingness or otherwise to invest is the critical thing in these models.…
