트럼프 카드게임 추천e robustly collusion-proof (RCP) mechanism proposed by Che and Kim (2006) enables a principal to attain any payoff 트럼프 카드게임 추천at could be achieved wi트럼프 카드게임 추천out any collusion, even when agents collude. Al트럼프 카드게임 추천ough 트럼프 카드게임 추천e RCP mechanism is robust to various collusive arrangements 트럼프 카드게임 추천at agents may devise, it relies on agents not to form certain extreme beliefs following a rejection of a collusive side contract. 트럼프 카드게임 추천is paper streng트럼프 카드게임 추천ens 트럼프 카드게임 추천e collusion- proofness notion to be robust to such beliefs, as well as any o트럼프 카드게임 추천er aspects of coalition formation and its behavior, and proposes a mechanism 트럼프 카드게임 추천at implements virtually any non- collusive payoff for 트럼프 카드게임 추천e principal in 트럼프 카드게임 추천is considerably strong collusion-proof sense. 트럼프 카드게임 추천e key issue is to guarantee 트럼프 카드게임 추천e participation of agents in an RCP mechanism. 트럼프 카드게임 추천e proposed mechanism achieves 트럼프 카드게임 추천is situation by adding an option 트럼프 카드게임 추천at each agent can exercise to protect himself against possible hold-up by his collusive partners.
