Consider the matter from the point of view of someone prescribing  
policy.  The model is a proposal of how the economics of the  
matter in question work.  Unless one assumes certainty about how  
the economics works, policy and action is impossible.  One  
proceeds [dare I say it?] as if there is certitude.  Action,  
necessarily ASSUMES that things are a certain way, or action  
becomes impossible.  Of course the actor is well aware that  
everything is only probable, but at the moment of action the  
assumption is that things are definitely a certain way.  That  
includes the assumption that other actors in the system behave in  
a certain way, and, unless specified otherwise, have full knowledge  
of the relevant environment of their acts.   
 
The assumption of perfect knowledge is a derivative of the policy  
application of Economics
