Study Notes

Monte Carlo Simulations in Capital Budgeting

  • Monte Carlo simulations model uncertainty in capital budgeting projects
  • They predict different outcomes by considering random variables
  • The technique helps understand risk and uncertainty impacts
  • Initially developed by Stanislaw Ulam and John Von Neumann
  • Simulations are used to evaluate the probability of various project outcomes

How Uncertainty is Accounted For

  • Financial analysts assess new investments in two phases
    • Phase 1: Estimates potential outcomes and determines initial projections (NPV, IRR, etc.)
    • Phase 2: Identifies risk sources, seeks risk mitigation/monitoring strategies

Overview of Capital Budgeting Analysis Tools

  • Break-even analysis: Finds the input level where project NPV is zero
  • Sensitivity analysis: Shows how NPV changes with changing assumptions
  • Scenario analysis: Evaluates different sets of assumptions (various outcomes)
  • Monte Carlo simulation: Models risk using probability distributions of variables

Break-Even Analysis

  • Used to determine the level of an input at which a capital budgeting project has a zero net present value (NPV)
  • A common break-even level considered is the internal rate of return (IRR)
  • For each parameter, calculate the value where NPV equals zero.

Sensitivity Analysis

  • Breaks down NPV calculation into component assumptions
  • Shows how NPV changes when underlying assumptions shift

Scenario Analysis

  • Shows the distribution of possible outcomes
  • Results in a probability distribution of investment project outcomes

Monte Carlo vs. Sensitivity Analysis

  • Monte Carlo: More realistic risk and uncertainty simulations, many variables simultaneously over time

Steps in Monte Carlo Simulations

  • Define probability distribution of each input variable
  • Draw a random value from each variable distribution
  • Calculate project metrics (e.g., NPV, IRR)
  • Repeat the process many times
  • Create distributions of outcomes.

Step 1: Modeling Project Uncertainty

  • Consider realistic future assumptions

Step 3: Impact on NPV

  • Examine the distribution of net present value (NPV) from multiple simulation runs

  • Calculate NPV at various points in the distribution.

Monte Carlo Key Takeaways

  • Allows more realistic assumptions about risk and interactions in project variables over time
  • Gives fuller descriptions of project risks
