Economics. I do not think it means what you think it means. (Destiny)

There is very much an economy between your resources and the game's vendors. Some charge more than others; Eris scams you for Heavy Synths, and Banshee requires some pricey glimmer exchange, while Xûr has the best deal, but his sales are never guaranteed, and he requires a resource that you might want to use on other things.

The player is given options, all depending on availability, and what resources he has on-hand. That sounds very much like an economy to me.

Cody is mad because he demands that Xûr have an item in stock, despite it never being a guarantee. He's the bob-cut woman in the supermarket demanding to see the manager because they're out of his favorite brand.
