"Moneyness" is a term in finance :-)
Do you mean "better extract profit" or do you mean "generate value with higher productivity"?
And my initial question still stands: what is your aim and what problems do you want to solve?
From what I gathered if two sellers would sell the exact same product but another seller could sell it at double the price it would become a favoured node. If they were not interchangeable products you could try to argue that the difference must be between the quality of the products. However if the same product has the same use value the measure is more about better extracting profits. There is the effect that given choice of equal product at cheaper or higher price a consumer ought to go with the lower cost. Competetive effects are supposed to kill off overpriced products but giving a bonus to seller for having a big mark up dulls their teeth.
I posted a stupid question a couple of weeks ago and got some good feedback.
@ChristianKl suggested that I start building a model of hypercapitalism for people to play with. I have the first one ready! It isn't quite to the point where people can start submitting bots to play in the economy, but I think it shows that the idea is worth more thought.
