Research errors in economics are not uncommon, but they are usually caught at an early stage, as happened once to me in a prepublication draft. Sometimes errors are not discovered until later, when they are working papers, as with Reinhart and Rogoff, or after publication, as with Nobel laureate Ken Arrow, who had to correct a mistake in the proof of his famous impossibility theorem.
经济学中的研究错误并非稀罕事，但它们通常在早期阶段就被发现了，我的付梓前草稿也出现过这种情况。有时错误直到成为工作论文之后才被发觉，莱因哈特和罗格夫的论文就属于这种情形；也有可能在发表后才被发觉，诺贝尔奖获得者阿罗（Ken Arrow）就遇到过这种情形，他在证明他著名的不可能定理时犯了一个错误，不得不做出纠正。
