5F推: 你拿到的短期成本函數已經選了L,而長期就是選最適規模:K*03/08 06:55
6F→: , 將K*代入，就是長期成本函數。03/08 06:55
8F推: 平均每人消費極大化，一階條件就可以導出，MPK=n+d, 從02/09 14:42
9F→: 圖形也可以看出兩條線平行時，平均每人消費最大，這題沒02/09 14:43
10F→: 有n，就是MPK=d=2%, 而且就算沒剛好等於，由MPK遞減的特02/09 14:43
11F→: 性，也可以判斷出是高於或低於黃金法則水準。02/09 14:43
12F→: 所以你思路不少盲點，可能也跟補習班成長這單元往往教不02/09 14:45
13F→: 好有關。選擇題錯五題以內都還好，申論只要過程別太誇張02/09 14:45
14F→: ，結果是對的，分數幾乎都是全給，但通常上榜重點也不會02/09 14:46

31F推: "誘發性支出" <= 從哪來? 不就所得嗎 所得是經濟模型中的06/07 02:07
32F→: "應變數" 也就是你已經在討論後面階段了 再往前一定先有06/07 02:08
33F→: 個"自變數"在影響所得 也就是自發性支出06/07 02:09
34F→: 自發性支出增加 => 所得增加 => 產生誘發性支出 =>06/07 02:09
35F→: 所得再增加 => ... 你可以代數自進去 把每次增加的所得06/07 02:10
36F→: 列出來 會形成等比數列 總和就是等比級數 應該是高中生有06/07 02:11
37F→: 辦法算出來的06/07 02:11
11F推: 政府要花錢阿01/29 00:19
