Risk Sim

Everyone who has been to business school is familiar with business simulations.  These computer models simulate economic conditions and the competitive environment of one industry or another.  You spend the weekend, or time during an offsite competing against either the computer, or your peers to see who can run the most successful company according to the simulation.

 

Business simulations are fun, and students and training participants enjoy them up to a point.  Simulations attempt to get participants to learn how to juggle the multitude of factors that affect the outcomes of business decisions. 

 

Business simulations function by taking a set of rules, and correlations between rules and create outcomes based on the participant’s decisions. They are based on a set of assumed cause and effect relationships. If a simulation is played for too long of a period of time (or too many rounds), then it has been my experience that participants start to focus on reverse engineering the simulation, rather than thinking about making good decisions.

 

This raises an interesting question; “Can we create a risk management simulation?”  In other words, can we create a realistic simulation that allows a risk manager to develop their skill at making risk based decisions?  Are there a set of well known rules and correlations – cause and effect mechanisms, that will allow the construction of such a simulation?

Great Versus Relevant

As a university professor I always start to get excited again this time of year as fresh new batches of students are about to arrive on campus.  Another cohort of great minds to fill with relevant knowledge – or so we tell ourselves as we start preparing our class syllabus.

 

One of the strange characteristics that we note – or at least in business schools, although I suspect it carries over to other faculties as well – is that the great students on average underperform the average student later in life in their careers.  Of course there are always exceptions to this – some great students have outstanding careers.  Typically however the most gifted academically under-perform their more mediocre peers.

 

There are a couple of possible explanations for this.  The first and most obvious is that B-Schools teach and measure on all the wrong topics and metrics.   I believe this is true and have a forthcoming academic paper titled “Business School Myths” that outlines my arguments why this is so. 

 

A second and related explanation is that business schools teach great knowledge, not relevant knowledge.  Compounding this, students from the first days of kindergarten are rewarded for focusing on great knowledge not relevant knowledge.  (“Great” meaning both the great ideas –dead poets etc. – as well as the great volume of material that needs to be covered to satisfy the standard curriculum which is designed by a committee – insert your own design by committee joke here.)  What is “great” in terms of ideas is rarely questioned, other than by the kindergarten and primary student, and they are told that they are too young to understand.  (Anyone who needs to relearn how perceptive kids are needs to read the comic strip Frazz.)  For instance we continue to teach Shakespeare without question.  I have nothing against Shakespeare (in fact I rather like old Will’s writing and themes), but should we unquestionably continue to teach it simply because that it was taught last year?  Have there not been any relevant (more relevant) plays or stories written since?

 

It seems to me that risk management is also trending towards “great” versus “relevant”.  Regulators, shareholders, rating agencies, Boards, and others all want to see evidence of “great” risk management in place.  Here too “great” has two meanings; (1) what is considered the orthodox risk metrics and (2) a lot of it.  But does anyone ask if the risk management is relevant?

 

Getting back to the point about great students underperforming on average the more mediocre students, it is interesting to ask the question; “Does great risk management, on average, underperform mediocre risk management?”  If “great” means traditional and volume, and not relevant, then I believe that “great” risk management will indeed underperform mediocre but relevant risk management.

RMBWA (Risk Management By Walking Around)

Had dinner last night with a junior trader.  Really bright guy.  Has a terrific future ahead of him.  Along with the usual conversation about sports, cigars and travel etc., we starting talking about work.  In a nutshell he laid out many of the issues that he observed in his workplace.  The conversation was nothing out of the usual, and exactly what you would expect when two guys get together for some brew and grub. 

Walking back to my hotel I started to think about how useful it would have been for senior risk managers to have listened in to our conversation.  This front line trader knew where all of the weak links in the system were, the daily struggles to deal with them, and had some great ideas of how the issues could be remedied.  

What my friend did not have a knowledge or an appreciation for is all of the political B.S. that the senior risk people have to put up with on a daily basis as they try to align the various functional units, each of which has a specific agenda (and a senior manager who has their own agenda that is likely disconnected from the front lines). 

When I was in B-School in the early 90’s, one of the key buzz-words was MBWA – management by walking around.  In other words, senior managers should keep a handle on the business by keeping in contact with the front lines. 

Dinner last time convinced me that it is time for risk managers to RMBWA.
