In the context we are talking about we do know the expenses beforehad or if we join the pool after the product is already complete we definetely know what it costed.
Even if you didn't know the (exact) costs if both producers tell you what kind of production process they are going to use it is easy to favour one of them if it seems economically superiorly efficient. More roundabout but still prevents runaway costexplosions as you get unselected if you totally lack budjet discipline. |
