Dealing with Uncertainty in Scenario Analysis: Stochastic vs. Deterministic Approaches

Hear from Ron Dembo Founder and CEO of as we apply stochastic thinking to the challenge of climate scenario analysis.

One of the most difficult aspects of managing climate risk is its inherent uncertainty. Because we can’t know with absolute confidence what our future climate economy or society will look like we therefore can’t know exactly when where or how intensely climate risks will manifest.

A technique commonly applied to this problem is scenario analysis. By building a picture of what the future might look like firms can formulate risk management strategies appropriate for that scenario.

However today’s guest believes we’re only scratching the surface of what scenario analysis can do for our financial institutions. In today’s episode we’ll home in on the idea of stochastic scenario analysis; what it is how it works and what makes it different to the traditional approach to scenario analysis. We’ll explore:

  • The difference between deterministic and stochastic scenario analysis;
  • The advantages of using large sets of scenarios generated by expert judgment; and
  • What stochastic scenario analysis means for risk professionals.
