The existence of bubbles and crashes in such a simple context was unsettling for the economics community that tried to resolve the paradox on various features of the experiments.

In particular, starting inGunduz Caginalp and collaborators [22] [31] modeled the trading with two concepts that are generally missing in classical economics and finance.
