Quality Uncertainty in Early Economic Thought
梳理了罗马法和中世纪思想家对质量不确定性的讨论，揭示早期经济思想如何预见了现代信息经济学关注的问题，对经济思想史和信息经济学研究者有参考价值。
This article highlights the contributions of early economic thought to quality uncertainty. Both Roman law regarding fraud and medieval thinkers (such as Vacarius, Thomas Aquinas, Henry of Ghent, and Astesanus of Asti) scrutinized asymmetric information and shared uncertainty regarding product quality, although not in the same terms as the modern literature. This retrospective analysis will help clarify how early economic thought can enlighten us both on the nature and consequences of quality uncertainty and the mechanisms to address it, and may have even predicted the issues that have been addressed by modern information economics.
