Risk = Probability X Consequences. Really?


“Wall Street thought it had risk all figured out…” should read that they figured out a marketing message given kudos by the number of Phd’s, MBA’s etc. employed by organisations whose appetite for individual/collective wealth and power was enabled by regulatory and credit (rating) regimes that suited the aspirations of politicians ALL at the expense of their citizens (customers) i.e. those that give them the means to function.

Their own greed and inability to continue to control information that exposed it, has been their undoing. Access to INFORMATION has enhanced our knowledge to such an extent that we have been able to recognise the MISINFORMATION that was presented as ‘knowledge and expertise’.

They created and profited from a volitile financial environment that, once globally interconnected, is beyond their control but, for as long as profits can be privatised and losses socialised, they will not suffer…until what has been ‘hidden in plain view’ can no longer be tolerated or sustained.

Time is nearly up.

Probably the most frequently used definition of risk is this one:

Risk = the Probability of something happening X resulting Cost/Consequences

This definition is flawed because of two fundamental reasons, which the formula itself suggests very eloquently:

1. Estimation of probabilities of future events is very difficult (while it is considerably easier when talking of past events). Rare events have very low probabilities and these are extremely difficult to estimate due to the fact that the sample of available data is very small (what is the probability of an event similar to 9/11?). Since this factor multiplies the “cost” in the above equation it is of paramount importance.

2. Estimation of the costs/consequences of these events. This is most difficult. Even after a catastrophic event it is difficult to estimate the total damage and cost.

However, the most important flaw is hidden and it is conceptual…

Is it Possible to Make Predictions?: don’t ask an Actuary or statistician


Probability and Measure
Probability and Measure (Photo credit: John-Morgan)

I don’t consider myself particularly clever but I understand that, when it comes to matters of finance and insurance, we CANNOT predict the future. So, why is it that extremely clever, highly educated, people don’t appear to understand OR are prepared to feign ignorance?

“…contemporary “predictive machinery” is based on statistics – looking back in time, building some model of what has actually happened, extrapolating into the future. The concept of probability plays a central role here. Bertrand Russell is known to have said, back in 1929, that “probability is the most important concept in modern science, especially as nobody has the slightest notion what it means”. In fact, probability is not a physical entity and it is not subjected to any laws in the strict scientific meaning. As a matter of fact, there are no laws of probability. If a future event will take place, it will do so irrespective of the probability that we may have attached to it. If an extremely  unlikely event will happen, it’s probability of occurrence is already 100%”

The Last ‘Mystery’ of the Financial Crisis


“As you know, I had difficulties explaining ‘HOW’ we got to those numbers since there is no science behind it,” confesses a high-ranking S&P analyst. “If we are just going to make it up in order to rate deals, then quants [quantitative analysts] are of precious little value,” complains another senior S&P man. “Let’s hope we are all wealthy and retired by the time this house of card[s] falters,” ruminates one more.

Complexity, risk, uncertainty and change

Business management, particularly for those intent upon ‘change’ or responsible for managing exposures, needs a rigorous, objective, measurement of the endogenous properties (complexity) that enables the functionality from which (through interactions with exogenous parties) the business generates the revenues that sustain it in changing and turbulent economic times.

“Complexity increases cost and decreases flexibility — often in unforeseen ways — and also tends to decrease stability,”….

Peter Leukert, CIO of Commerzbank

It is the number, nature and integrity of dynamic, multi-scalar, interactions that are the sources of strength (enabling performance greater than the sum of the parts). The ability to distinguish and respond to ‘signals’, that maintain the variety, effectiveness and agility of the complex system, from the ‘noise’ of flawed metrics, self-serving culture, hierarchical structure (silos), skewed incentives – of an unsustainable, failed or failing, model (reliant upon  assumption, reflexive, subjective, statistical analysis and prediction) that has its foundation in flawed (linear) economic thinking.

We won’t get different or better answers while we keep on asking the same questions.

For meaningful change to occur and to be sustained requires a rigorous justification, sufficient to counter financial projections that satisfy the goals of C-level short-termism that are detrimental to the stability and long term health of the business.

Business Insurance:: ISO 31000 should we believe the hype?

Apparently,

“…risk managers should use standards such as ISO 31000, “because standards, no matter what kind or which ones, support key tools and processes.”“Standards allow you to proactively address risks with some discipline,” he said. “Standards also relate well to the whole idea of focusing on outcomes.”

Surely the focus should be upon being proactive and ‘managing’ emergent risks, NOT outcomes!?

Where, I suspect, NASA have a distinct (informational) advantage is that the multi-scalar interactions among components, processes, networks of sub-systems and systems are each rigorously tested at every point in assembly and operation…
