Episode notes

Author and consultant Luca Delana talks with Econ Talk host Russ Roberts about the importance of avoiding ruin when facing risk. Along the way, Delana makes understandable the arcane concept of ergodicity in everyday life. In an ergodic system, the performance or outcome of any individual is likely to match up with the average or be close to it. For instance, if you have a bunch of people all flipping a coin a hundred times, they're likely to all get similar outcomes. This also relates to the work of Naseem Taleb and others.

In this episode we answer questions from MyContactInfo, Anonymous and Arun. We discuss a podcast and article about the concept of Ergodicity and how to apply it, a variation of the Golden Ratio portfolio from one of our listeners recently discussed in an interview, and the illusory benefits of dividend-paying stocks and related delusions.

And THEN we our go through our weekly portfolio reviews of the seven sample portfolios you can find at Portfolios | Risk Parity Radio.
