Ergodicity explained through a simple econometric model
Every society (to the extent that there is such a thing) has its own set of values based on which decisions are made. Let us call the place for those decisions the economic system, and secondly, let us assume that this system follows a dynamic model. It can then be said that the system is ergodic when the set of values underneath have been accurately incorporated into the systemic model and have sufficient explanatory value so as to conduct decisions based on it 'ad infinitum'. In that case, there is ergodicity. Of course this is an immense oversimplification because it assumes that a system can be explained by a single model, which is certainly not the case at macro-economic level. The logic serves the purpose of this article.
