I'm in search for a title that says: You can expect to read about how economic efficient different things are when compared against each other.
As I need a noun, grabbing the word economical and turning it into economicality of doesn't really cut it, because I don't even think that is a proper English word.
Is economics of the correct term? Somehow that gives a more internal feeling, as in economics of scale, and not as in
these things affect overall cost in such and such a way
Is there a better term than the non-existent word economicality?
