Okay, i defer to you on the economic literature understanding, but i still think it is weird to say:
We are dealing with pairs of ideas -pairpairsingle item.
It scans odd to me. It's semantics for sure, but it sits badly in my mind.
Aha, I get it now. Misunderstanding.
Each pair has a component from economics, a concept or cluster of concepts, and a component from SF, one or more pieces of work. So:
Is it clearer?
Much clearer, thanks Alberto
