Summary

Economist Ole Peters discusses ergodic and non-ergodic systems in relationship to expected value versus temporal average growth, using the example of a simple coin flip gambling situation. Peters explains that although in aggregate the population experiences positive expected value when taking the bet, the typical person does not. By analyzing the individual's risk preferences and applying the Kelly Criterion, Peters offers optimal bet sizes that maximize geometric growth rate for long term gains. He further introduces the concept of diversification and its importance in risk management.
