Though behavioural economics has been popularized over the past decade in both industry and pop culture, it seems that not much has changed with regard to the standard economic definition of rationality.
This is because for the most part (in my view and experience with my professors) it seems to have been irrelevant or unconvincing for the game theorists who deal with very similar theory to the behavioural economists. This is where a "super-micro" theory of consumer and prodoucer behaviour is generated and analysis takes place.
Now im not a huge fan of behavioural economics, but points like discontinous time preferences and prospect theory are useful for adding a degree of realism to models.
This all being said, (except for a few articles on behavioural game theory) why has a large chunk of young game theorists decided to stay away from "behavioural" elements?
