In Renegotiation in Repeated Games (1989), J. Farrell and E. Maskin present, among other results, sufficient conditions for payoffs to be “weakly renegotiation-proof”. We show that a step in the corresponding proof is not correct by giving a counterexample. We then provide a correct proof with slightly more demanding sufficient conditions.
