Levered Beta
measures the risk of a firm with debt and equity in its capital structure to the volatility of the market
Unlevered beta
asset beta
measures the market risk of the company without the impact of debt
Definition of Decision
consciously or unconsciously
between alternatives of action to realize objective
Situation of Certainty
seldom, perfect level of information
every enviro, nmental condition probability of occurrence of 1 or 0
Situation of Risk
imperfect level of information
total of all probabilities of occurrence is 1
Situation of (Complete) Uncertainty
a certain environmental condition cannot be assigned any
probability of occurrence, but it will occur
risk averse decision maker
choose the one alternative expecting the smallest danger of sustaining a loss
willing to take risk decision maker
highest possibility of gaining a profit
risk neutral decision maker
choose the best alternative on average (loss, profit)
Bayes-Rule
calculate Expected Value
E(p) = eij * pj
and sum up, choose highest
Maximin-Rule
choose the maximum of the minima of each row
Maximax-Rule
choose the maximum of the maxima of each row
Hurwicz-Rule
compromise between Maximin and Maximax
λ = Optimism-Parameter
λ > 0.5 willing risk
λ < 0.5 risk averse
best result (row maxima) is multiplied by λ, the worst (row minimum) by 1-λ
Laplace-Rule
Assumption: All environmental situations same probability of occurrence
mean over eij, choose highest
Savage-Niehans-Rule / Minimum-Regret-Rule
minimize his forgone benefit resuling from not choosing best
regret measure: difference best and the alternative (column wise)
choose the alternative with smallest maximum regret measure (row wise)
