To infinity and beyond: A general framework for scaling economic theories
提出一个通用框架,通过移除有限性假设来扩展经济模型的结果,仅需基于定理陈述而非证明,适用于多种理论如显示偏好理论。
Many economic models incorporate finiteness assumptions that, while introduced for simplicity, play a real role in the analysis. We provide a principled framework for scaling results from such models by removing these finiteness assumptions. Our sufficient conditions are on the theorem statement only, and not on its proof. This results in short proofs, and even allows us to use the same argument to scale similar theorems that were proven using distinctly different tools. We demonstrate the versatility of our approach via an array of examples from revealed‐preference theory.
