I'm not sure if you have read Mises, since I have not seen any mention, but in his book Human Action ( https://mises.org/library/human-action-0 ) 'attention economy' is in fact the centre of the entire treatise. Specifically, the process of decision between what one will do, and what one will not do, since the time of our life is the most scarce resource we have.

The central axiom of this book also is all about how we do the decision making process, the Action Axiom, which gives you the primary rules by which we evaluate and economise our use of our time (and attention). It is about minimising pain, and increasing pleasure.
