經濟學是否有較為權威的分類方法？

今天的午餐很好吃啊！

當然是有的。請移步這個網址：AEAweb: JEL GUIDE，或者這個：AEAweb: American Economic Association: EconLit

以上是JEL的分類方法，相信看過經濟學文獻的應該都不會陌生。這個分類肯定是最權威的，沒有之一。

但是這個分類的缺陷（優點）之一就是太細。總的大類上，分成了A－Z共26個大類，已經很多了，然而細看，每個大類還有很多很多小類。

在我們很多人看來，game應該算微觀，更應該分到D Microeconomic裡面，但是跟計量放到了一起，而實驗經濟學也放在了同樣一個分類裡面。

此外還有比如 I：health, education and welfare，而J: labor and demographic這兩個分類，雖然不同，但是其實有很多交叉。比如 I26 Return to Education我學習的時候都是從 J: Labor下面學的，但其實分類時不一樣的。

還有諸如N: Economic History裡面的分支幾乎跟其他分類都有重合，而現在經濟史學的研究又很大程度上跟 O Economic Developlment 重合。
