Investment Decision-Making Accounting for Risk
Problems with Sensitivity Analysis • No decision criteria: What to do? • Only one variable at a time is analyzed • Solution: scenario analysis (What if? Analysis) on spreadsheet. (* see http://office.microsoft.com/en-us/excel-help/use-the-scenario-manager-feature-in-excel-HA001199652.aspx?CTT=5&origin=HA001199648 ) Alternative approach: Expected Net Present Value (ENPV) Analysis
Example: ENPV Ignore (past) Fixed Costs
Example: ENPV (cont.) Include (forgone) Opportunity Costs
When businesses (or investors) take on more risk, they generally require a higher rate of return – meaning that the discount rate used for evaluating ENPV must be higher when the risk is greater. Risk-Adjusted Discount Rate (RADR)
