Project Appraisal Under Risk Flashcards
What is a risk?
A condition in which several possible outcomes exist, the probabilities of which can be quantified from historical data
What is uncertainty?
The inability to predict possible outcomes due to a lack of historical data
What is sensitivity analysis?
Analysis of changes made to significant variables in order to determine their effect on a planned course of action.
Lower percentage in a sensitivity analysis?
The more sensitive the NPV is to that project variable,
Advantage of sensitivity analysis?
Sensitive the project is to changes in any of the original estimates
Identifies the critical success factors for the project
Limitations of sensitivity analysis?
Assumes data for all other variables is accurate
Sensitivity analysis does not provide a decision rule
What is a simulation?
A technique which allows more than one variable to change at the same time
1st stage in a Monte Carlo siituation?
Specify the major variables (e.g. revenue and costs)
2nd stage in a Monte Carlo siituation?
Specify the relationship between the variables
3rd stage in a Monte Carlo siituation?
Attach probability distributions to each variable and assign random numbers to reflect the distribution
4th stage in a Monte Carlo siituation?
Simulate the environment by generating random numbers for revenue and costs
5th stage in a Monte Carlo siituation?
Record the outcome of each simulation
6th stage in a Monte Carlo siituation?
Repeat the simulation many times to obtain a probability distribution of the possible outcomes
Advantages of simulation?
Data can be used to calculate an expected NPV
Disadvantages of simulation?
Very time-consuming and expensive
Monte Carlo simulation is not a technique for making a decision
