微觀經濟學有甚麼主要 Formula 必知?? 例如:Marginal Profit (MP) = Marginal revenue (MR) - Marginal cost (MC). 越多越好!! 考試溫書用!! Thanks
最佳解答:
讀 Micro 冇公式背,重要係背定義。 仲有係經濟學入面唔會有 MP ,因為 profit 係 unexpected 唔會有邊際概念,Micro 冇咩數計,全部都係寫 assey 多,自己慢慢背啦。 2006-12-11 23:21:08 補充: 都幾好嘢喎equi - marginal principle 都可以係一條式,搵啲讀過 AL Econ 黎睇睇, equailibrium condition 係一個概念,佢入面有定義,你背個定義啦。有三個 equailibrium condition1) Allocative efficiency / Economic efficiency / Pareto optimal condition2) Consumption efficiency 3) Production efficiency 2006-12-11 23:22:25 補充: 1) Allocative efficiency is a state where it is impossible to re-allocate so that one individual gains without loss to another . It means that MUV ( Price ) is equal to MC . 2006-12-11 23:22:33 補充: 2) Consumption efficiency is a state where all consumers have the same MUV of a good 3) Production efficiency is a state where all firms in the marker produce the good with the same . 2006-12-11 23:23:16 補充: 呢三個定義我自己都唔知係邊到搵條公式出黎,話有公式都幾好嘢。 2006-12-11 23:26:53 補充: Interest , Income , Wealth 個課係要計 discounting ,不過重點係佢哋嘅定義因為佢哋可以係 flow concept , 可以係 stock concept 2006-12-11 23:29:06 補充: 3) Production efficiency is a state where all firms in the marker produce the good with the same MC . 2006-12-11 23:33:45 補充: 要記住 Micro 唔同 Macro ,Micro要讀得好一定係背書,同係咁睇書,林本利呀、Chan & Kwok;而 Macro 係重數字多啲,不過重數字之餘都要有經濟概念,否則只得數字冇經濟概念嘅數字係冇用,呢句係佛利民講。 2006-12-13 00:33:49 補充: 你咪同張五常講唔背書就攞高分囉,無錯張五常係唔想學生背書,創新咁去答自己想答嘅答案,而老師亦會俾分,我夠膽講一句 Section B 你唔背你攞唔到分,除非你係攞 A 個勁人,咁唔該你俾個 Econ A 我睇。 2006-12-13 00:36:05 補充: 如果你唔係天才而想高分又唔勤力咁唔該你日日去拜神,睇吓有冇奇蹟出現,唔係就乖乖咁向現實低頭,自己冇又份讀 Econ 就要背嘢,如果唔背又想高分,世間上邊到會有免費午餐,呢句係佛利民講嘅。 2006-12-13 00:38:14 補充: 如果想講理想話改革個考試,唔該你叻啲入學統局做改革,或者去做行政長官,有人夠膽係香港考試制度下講理想,咁你自己慢慢考飽佢,要高分就要勤力。 2006-12-13 00:47:02 補充: 你自己讀 Econ 都知,想獲得一嘢物品就要付出代價,不一定係金錢,可以係勤力、天才或者行運,我想問你考試會靠行運,咁你準備考十次都得啦;如果你係天才,咁你咪入去打天才波囉,唔係就唯有用一個保險多少嘅方法去考好個試,呢個係我個人睇法,每個人觀點唔同,歡迎討論。

其實, 讀咩科都好, 都要背, 只係睇你背既方法係如何~ 如果你係一o的為背野而去背, 即係讀死書, 你背既方法肯定係好無效率, 例如, 背一條方程式, 跟著見數就代, 當中無理解個條方程點樣出來, 呢一種方法效率好低, 因為你唔識以一應百, 隨機轉變~~ 雖然樓主話, 當你理解或明白個概念, 咁就根本唔需要背, 但其實我地理解既時候, 已經背左, 只係背既方法唔同, 因為理解既時候, 再加入思考, 當中所要記既野已經係腦入面重複出現幾次, 實際中已經背好, 只係背既方法唔同, 呢種背既方法係有效率好多~~ 如果真係好似樓主所講, 剩明白而當中無背既過程, 咁你所學到既, 就只會係思考方法, 而唔係經濟學.... 第一回覆既人亦太過份緊張, 雖然樓上所理解既野同你唔同, 都唔需要寫得咁激, 討論應該平心靜氣, 而唔係為堅持己見而絕對反對其他意見, 咁樣唔係討論, 只係純綷係你個人solo~~|||||如果係基本的 Marginal benefit = Marginal cost Indifference curve: Marginal rate of substitution = Relative price Marginal use value = Price (Consumption efficiency) Marginal revenue = marginal cost (Production efficiency)同時亦是Wealth maximizing 的首要條件 Marginal use value = marginal cost(Society efficiency) Elasticity: Change in Quantity / Change in Price Interest, Income , Wealth: Present value * (1 + interest rate) = Future value Present value = Future / (1 + interest rate) 咁Interest ,income 同wealth係照塞番D數入去 基本上以上的formula是要知道下,還有其他濕碎野的原理和上面很類似,所以不列出來了,希望幫到你吧!
