Class 14 Flashcards
General criteria to evaluate relative merits of alternatives RM tools
- choose tools to support org objectives
- choose tools to promote efficiency (org characteristics affect the efficiency of various options)
choose tools to support org objectives
- vision/mission (which offer info on):
- risk attitude
- risk tolerance
risk attitude
- relatives values of negative effects of risk
- risk averse or want more volatility?
- businesses make these decisions based on what shareholders want
risk tolerance
- level of “acceptable” worst possible outcomes at given probability
- whats the point where you think there is too much volatility?
choose tools to promote efficiency
- employ best opportunities to pool
- encourage efficient risk/loss control
- minimize current taxes
pooling
- combining loss experience across a group (gives you a more accurate estimate)
- you have to factor in both peoples probabilities of loss (may include a loss amount per individual numerous times)
equation for expected loss (mean)
loss1 (p1) + loss2 (p2) +…+ lossx (px)
equation variance
(loss-mean)^2 * probability
equation for stdev
sq. rt. (x-m)^2 * p (sq. rt. of variance)
what is a benefit of pooling?
the stdev. per individual decreases
mutually exclusive
don’t depend on one another
collectively exhaustive
all outcomes considered
consider what happens when many people pool their outcomes
- the expected loss per individual is unchanged
- the standard deviation per individual declines
what happens to negatively correlated events?
they are dampened
what happens to positively correlated events?
they are strengthened
