本文提出了一个适用于代理人具有非均匀扭曲信念的经济体的福利标准。而不是采取一个立场,谁的信念是正确的,我们的标准断言,分配是信念中立的有效(无效),如果它是有效的(无效)下的任何凸组合代理的信念。虽然这一标准给出了一个不完整的社会分配排名,但它可以识别在广泛的经济环境中由相互冲突的信念驱动的正和负和投机。
This paper proposes a welfare criterion for economies in which agents have heterogeneously distorted beliefs. Instead of taking a stand on whose belief is correct, our criterion asserts that an allocation is belief-neutral efficient (inefficient) if it is efficient (inefficient) under any convex combination of agents' beliefs. While this criterion gives an incomplete ranking of social allocations, it can identify positive- and negative-sum speculation driven by conflicting beliefs in a broad range of economic environments.
