Estimating Bubbles

In a presentation for more than 200 actuaries at 'Actuarieel Podium" (actuarial Platform) on October 2 (2013) (Actuary Day) in the Netherlands, I tested the ability of Dutch actuaries to estimate the number of bubbles in a bottle of champagne.

Take the Test

Test your own bubble estimation ability. Think for a while:

How many bubbles are in a bottle of Champagne?

If you think you've got the right answer, check it by clicking on the picture below...

If the order of magnitude of your answer was right: Congratulations!
If not, like most actuaries at my presentation, one thing is clear:

As actuaries we fall short in estimating bubbles!!!! (crises)

Key question is: why can't we estimate bubbles?

Short answer: because we have been only professionally trained in estimating relatively small numbers and small risks, not (systemic) crises.

One thing is sure: we need to fix this educational bubble-lack in our professional actuarial training.

49 Million Bubbles in a bottle of champagne may seem much, it's nothing compared to the U.S. Debt:
