Absolute Advantage and Comparative Advantage
Comparative Advantage – can produce a product at a "lower opportunity cost". Absolute Advantage[outputs] – can produce absolutely more with the same inputs. Absolute Advantage[inputs] – can produce absolutely faster with the same inputs.
Absolute  Advantage  –  [outputs]  can  produce  absolutely more with the same inputs [more efficient]. Absolute  Advantage  –  [inputs]  can  produce absolutely faster with the same inputs [more efficient].  I Can do 8 push-ups . I Can do 42 push-ups. I have an  absolute advantage   in the production of push-ups. I can clean that  house in 4 hours. I’m more efficient.  I can do the same work in 3 hours so  I have an  absolute advantage .

Absolute Advantage [ Outputs   v.

And with   inputs   ( hours ), the   smaller number   indicates   absolute   advantage ; that country is   more efficient   because it can produce  a good   absolutely   faster   than the other   with the same inputs.
