How much impact does memory have on risk pricing? Have studies been done that demonstrate the limits of human memory on reputation in the Iterated Prisoner's Dilemma?

i.e. at what point (on average) does a player start to "forget" the actions of a previous opponent?
I'm not sure what you mean by risk pricing, but because you mention a repeated game, you might find the following papers useful. They present some theory about repeated games in which players have limited memory.
