An Analysis of Extendibility and Early Termination Provisions: The Importance of Framing Duration Safeguards
结合交易成本经济学与社会认知心理学，发现合同框架（如促进型可延长条款）能有效管理合同期限，减少交易问题，并作为关系管理工具，对合同设计和供应链管理有参考价值。
We augment transaction cost economics with social cognitive psychology to show that contract framing is an important element in minimizing issues in focal exchanges and managing buyer-supplier relationships. We find that exchange partners use promotion-framed extendibility clauses to address contract duration in the presence of greater physical distance, measurement difficulty, prior relationships in other businesses, and reusable technology. Our results suggest that contracts not only protect against exchange hazards, but also function as relationship management tools.
