咁如果HKEAA下年問:
Moving along a short run aggregate supply curve,
A. There will be a change in input prices
Moving along a aggregate demand curve,
A. There will be a change in the interest rate
應該跟考評局定cy? 上面2題揀唔揀得a?
cy解卷課堂話因為factors of shifting,咁move along就唔會有郁,即2題都唔可以選a
但係
1. interest rate 係factors of shifting
但根據考評局2013年marking, interest rate effect, interest rate會沿ad變
2. input price係factors of shifting
但根據practice paper同埋2016 marking亦見move along SRAS會有factor price adjustment
呢個情況要依cliff答案為依據定師弟為依據
不過唔希望我下年真係要再考
