Yes they are Maël Balac. I would however argue that a public price on an output would benefit small implementers and would be infinitely scaleable. In practice that would mean that a small clinic somewhere in a rural area could get the same terms (i.e. price) as the largest INGO in that country for their output. This is very different from what is going on right now, where the large INGO gets the grant and they dictate their terms to the small clinic (if at all, as often the small clinic gets cut out completely from the implementation). As long as the verification criteria are clear and standardized, anyone who verifies the occurrence of an output gets paid instantly the moment they submit the proof of verification.
