Alexander Ryzhenkov Unfolding the Eco-Wave Why Renewal is Pivotal System dynamics is a method similar to econometrics and mathematical statistics. Normally it is used to provide a rigorous analysis of models in closed systems (a system that is artificially created to simplify certain conditions, so that other conditions can be examined in more detail). Here, however, it is used for the first time to study capital accumulation, and the economic cycles. It is well documented that econometrics and mathematical statistics have their limitations. For the first time Unfolding the Eco-Wave sets out to prove that system dynamics does provide a coherent structure, language, and process for learning about and explaining economic phenomena in a way that is impossible to achieve with mathematical statistics and econometrics.
