The Failure of Risk Management
|
||||
(Why It's Broken and How to Fix It)
|
||||
by Douglas W. Hubbard
|

This is the commentary companion to [[hubbard_2020_failure]].

|

_The Failure of Risk Management_ (abbreviated here as tFoRM)
|
||||
|
||||
tFoRM is has two chief concerns:
|
||||
|
||||
* introducing actuarial methods to industries other than insurance.
|
||||
|
||||
* discrediting arguments against the use of actuarial methods
|
||||
in industries other than insurance.

As it is most commonly understood,

risk _always_ implies a negative impact.

Analyses that suggest otherwise are unhelpful.

For boolean cases,

risk can be represented as a vector of **probability** and **loss**.

[[hubbard_2020_failure]] is obviously inspired in some part
