會考經濟(22/04/2007) Ben 問

Ben問: wa 真係大開眼介...解釋十分之詳盡.太西利了
...如果 MCQ 41/02嘅y-axis由growth rate (%)改變成absolute change(unit:$), 敢個答案會係…?is that B?Rate of change / Growth rate / Percentage change 呢3樣野如果係正數slop 上升的話,姐係increase in a increasing rate?,slop 下降但係仲係正數的話姐係 incrase in a decreasing rate?咁如果個slop 係負數上升緊不過未到正數,係咪decrease in a decreaing rate? 咁如果個slop 係負數下降緊,咁係咪decrease in a increasing rate 呢?咁個slop 由正數下降到負數,咁低過左0個條line,係咪個實數係下降左呢?我仲想問下 potential GDP同actual gdp 同expansionary effect 同contraction effect 有冇out-到c 呢?多謝你的回答..

Ben,

1. 答啱啦, Ben!!!不過可以諗得簡單D。 MCQ 41/02(原裝版):若果y-axis係growth rate, 由於分子(G)上升10%, 多過分母(GDP)嘅上升(<10%),所以G/GDP會上升, 答案係A。(經濟友改編版):若果y-axis係absolute value (以$為單位),由於分子(G)嘅amount冇變, 而分母(GDP)嘅amount上升,所以G/GDP會下降, 答案係B。
2. Actual GDP(實際本地生產總值)緊係冇out syl啦, 而且勁重要添! 淨係Paper 1 過往10年都考咗5次, 必定用real life example問點影响GDP (唔洗寫明係actual, 因為understood o架啦) See 98-B11(c)(i) (4M);00-B9(b)(ii) (4M);01-B11(a)(ii) (5M);04-B10(c),05-B11(a) (5M), 同學只要記住GDP = C + I + G +(X-M) 呢條式, 然後諗下邊D component(s), 即 C, I, G, (X-M)升定跌, 就知道GDP升定跌, 經濟友遲下會講2007/08有セ嘢case考得。MC就做吓22/97; 29/97; 34/00; 29/01;29/04; 31/04; 30/05; 32/06吧!
3. Potential GDP(潛在本地生產總值) 都冇out syl, 主要考MC, 同學諗番F4學嗰4 factors of production (生產要素)就揾到答案, MC試吓做31/04。
4. 家吓個syllabus唔洗寫出expansionary (升)/contractionary (跌)effect, 講到GDP升定跌就OKo架喇。
5. 經濟友响呢度提番同學今年會考National income accounting(國民收入計算) out咗syl 有以下concepts:

(i) Components of GDP compiled under the income approach (用收入面計算GDP) , 例如MCQ 34/01, 26/02 就out 咗syl。
(ii) Calculation of NDP and NNP at market price/factor cost(以市價/要素成本), 例如MCQ 34/04 就out 咗syl, 但係GDP and GNP at market price/factor cost就要考嫁!

清楚嗎, Ben?
