Of Rats and Men
We are in the midst of writing a rather long post on the similarities between teenage girls with low blood sugar and daily and intra-day changes in equity prices. Namely, one can see huge swings in behavior, attitudes, and mood caused by seemingly very minor underlying events, e.g., “she looked at me the wrong way.” The “she” in this case being an eight-year-old sister.
However, we couldn’t complete that post because another thought keeps diverting our (limited) attention from it.
We were driving with the Chairman earlier today when she mentioned that the neighboring county was holding its fair, and that it was one of the largest county fairs in the state. She went on to explain whenever she thought of fairs and state fairs she would think of the book, Charlotte’s Web. (We’ve never read it because it was a girls’ book in our youth, and we did not read girls’ books: not then, not now.) As she explained, she particularly liked the chapter in which Wilbur the Pig goes to the State Fair, and Templeton the Rat tags along in the pig’s cage.
As she explained it, when the rat investigated his new surroundings, he thought that he had reached paradise. He was amazed at the wealth of delicacies that he could find on the ground – probably things like popcorn and corn dogs and ice cream cones and maybe deep-fried Snickers bars.
Upon hearing that, a question came immediately to mind: so, did he stay there?
See, we could imagine the rat believing that he had reached the proverbial land of milk and honey – in this case, half-eaten corn dogs and ice cream cones as far as the eye could see. It would seem to be an almost limitless supply. Except, except for the fact that state fairs only last for a week or two.
If he decided to stay at the fairgrounds after his swinish friend returned to the farm – if that’s where the pig went – then it could easily seem to have been the best decision of his life – for a week or two. Until the cleanup crews came and swept the refuse away, and until he began to face the following 50 weeks of deprivation and hunger.
Despite its completely deterministic and cyclical nature, the “great bust” or ” great depression” or “great famine” or whatever phrase he would have used to described the closing of the fair, would have seemed completely unpredictable and random. Templeton and his other rodent friends, could easily ask, “who could have ever predicted it? or “how could it be my fault?” Of course, it could be that things that seem to be too good to be true, often are.
Now, we are not comparing the recent (and ongoing) financial crisis with our imagined scenario of Templeton the Rat’s life. In our mind, economic crises tend to have endogenous causes, i.e., they erupt from within the system – not from an external source like a natural disaster or in this case, the predictable end of a two-week fair.
However, we do think the scenario is instructive. To Templeton the Rat, the destruction of his new environment would have seemed like a unpredictable tsunami. He wouldn’t have known when or if the good times – the fair – would end, and he wouldn’t have known what he didn’t know, i.e., very important characteristics of his environment.
It’s that aspect that is instructive, and it’s why we think that trading and investing firms should increase the scope of their risk management functions to the broader function of uncertainty management. “Uncertainty” includes the explicit realization that (1) not all randomness is measurable risk and (2) seemingly incomprehensible and unconsidered bad things can happen.
Note however, that just because such things are (currently) incomprehensible doesn’t mean that (i) that can’t be protected against and (ii) they can’t eventually be imagined through creativity and reason. The former is true because adequate protection against known harms can also protect against unknown ones; putting your house on stilts protects against known seasonal flooding and unknown tsunamis. The latter is true because that is the nature of human progress and the expansion of knowledge through experimentation and contemplation: think of humanity’s relatively recent discoveries of bacteria and viruses. Interested parties looking for more should read our essay, Uncertainty Management or our tongue-in-cheek post, The Role for Survivalists and Depressives in Uncertainty Management.
Finally, please note that we chose our title carefully. It’s a play on the line from the Robert Burns poem, To a Mouse, On Turning Her Up in Her Nest with the Plough. We Anglicize the line as: “the best laid plans of mice and men often go awry and leave us nothing but grief and pain.” We’d add that less thoughtful plans often don’t turn out that well.
