대기업과 중소기업 간의 신뢰 게임

Trust Game between a Small and Medium-sized Enterprise and a Big Business

We consider an extended trust game between a small and medium-sized enterprise (SME) and a big business (BB) with unobservable investment. The game has two Nash equilibria: the trust outcome and no trust outcome. By revoking the forward induction argument, we show that the trustee (BB) who has the option of burning money can single out the trust outcome. Burning money can be interpreted as a payment for nothing by BB in advance. Furthermore, by allowing cheap talk such as verbal assurance by BB to SME instead of burning money and using the refinement of neologism-proofness, we show that a more efficient outcome can be attainable.
