肯尼斯? J. 阿羅（Kenneth J. Arrow) 有哪些學術成就？

Kenneth J. Arrow, one of the most brilliant economic minds of the 20th century and, at 51, the youngest economist ever to win a Nobel, died on Tuesday at his home in Palo Alto, Calif. He was 95.

R.I.P 大家就不要佔一個回答了

博客A Fine Theorem的作者給自己挖了個坑，打算用四天時間寫四篇博客總結Kenneth J.Arrow的學術成就，結果第一篇發完之後，第二篇隔了5天，第三篇目前遙遙無期……

我也給自己挖了個坑，打算把這四篇翻譯過來，第一篇剛發在了專欄里：

Kenneth J.Arrow的學術成就（一）：社會選擇理論 - 知乎專欄

第二篇過兩天發，後面的等作者寫出來再發。

這裡姑且拿其中一段作答：

Arrow在諸多經濟領域都如此具有影響力，以至於想要在一篇文章中總結他的貢獻是完全不可能做到的。因此，我將把他的貢獻分成四個部分，並在本周內每天發布一部分（譯註：然而作者的第二篇拖到了5天後，第三篇還遙遙無期……）。今天的文章是有關於Arrow在社會選擇理論中的工作，明天則是有關一般均衡，周四有關創新，周五則是一系列由他做出開創性貢獻的經濟學話題（特別是環境經濟學、委託-代理問題和衛生保健經濟學）。

謝邀。不敢評價。RIP.

Everything in economics is called Arrow.

R.I.P.

在經濟學領域:

高山仰止，景行行止。

雖不能至，然心嚮往之。

沒資格評價。

貼一張鄙校肯尼斯阿羅教授史蒂夫杜爾勞夫教授的評價吧。

謝邀…… 才疏學淺

瀉藥。可能是我去年寫論文的時候總是查經濟學家才邀請我。經濟大師，不配評價。

謝邀，我不是太清楚。

豈敢妄論

瀉藥，真心不造自己何德何能被邀，第一次有點小激動，但是我並不知道答案呀~

Now, I am going to conclude by relaying a story told by Eric Maskin, one
of those five students of Ken』s to win the Nobel Prize. Ken』s junior colleagues had all observed that on almost any subject, Ken turns out to know a lot more about it than they do. So, they concocted a plan. They would all study up on one of the most arcane topics they could think of – the breeding habits of grey whales. On the appointed day, they gathered in the coffee room and waited for Ken to come by. Then they started talking about whales and the elaborate theory of a marine biologist named Turner on how grey whales found their way back to the same breeding spot year after year. Ken was silent... they had him at last! With a sense of delicious triumph, they continued to discuss whales, and Ken looked more and more perplexed. Finally, he couldn』t hold back. 「But I thought that Turner』s theory was entirely discredited by Spencer, who showed that the hypothesized homing method couldn』t possibly work.」

大一的時候學校請他來做講座，有幸擠進去聽了……

然而他講模型，我毛都沒聽懂……

拿Google搜經濟學的no go theorem，基本2個結果

一個蒙戴爾三角，另一個阿羅不可能

額，真的不知道呀；怎麼會邀請我這種小白

謝謝，我無法評價
