I don't think we have sufficient models as to why each transaction happens or not. For example, why did someone buy blueberries instead of raspberries?

That's only tangentially related to economics. There are no economic reasons why I prefer TBS to FPS games.

[RandomLensman]

That is what economics is about in no small part: preferences, their pricing and expression.

The pure movement of money isn't particularly interesting.

[thriftwy]

The pure movement of money is interesting as long as we have economic crashes happening from time to time that we don't predict.

Preferences and pricing is marketing, not purely economics.

[RandomLensman]

Movement of money isn't causing crashes, but, for example changes in preferences who to move it to or not.

What do you think economics is about if it doesn't include preferences and their expression.

Btw., we have nearly endless information on the movement of money and credit.
