201528D:
increase in wealth>increase in Mt Not Ma.

2014 (3): increase in General PL or higher GPL =/= increase in /higher cost of living.
Typical textbook example: Increase in GPL, but quality of goods of services also increased > cost of living may decrease.

2012:
U-rate = # of unemployed / Labour force
(1): # of unemployed may increase: They return to HK and seek job =/= they get the job successfully.
(2): Labour force increases, because they return from Macau to HK

Change in u-rate depends on percentage change in (1) and (2)

想補充少少的最尾兩條的

2014 Q26

              Food    Food Price      Clothing    Clothing Price
Year 1      44          5                       25               10
Year 2      36          6                       22                9

Cost of living 的計法係basic on base year 的買貨量的
即係
Cost of living of Year 1 = 44 x $5 + 25 x $10 = $470
Cost of living of Year 2 = 44 x $6 + 25 x $9 = $489
所以cost of living of year 1 係平D
So Option 3 is wrong

2012 Q24

U-rate = # of unemployed / Labour force
只要諗兩個極端
1) 澳門回流的人全部unemployed
2) 澳門回流的人全部employed
如果都得到same conclusion, 就可以推到結論
如果推唔到,就係undetermined

Let the returned worker from Macau be x
1) 澳門人來到全部unemployed
U-rate = # of unemployed + x / Labour force + x
U-rate increase

2) 澳門人來到全部employed
U-rate = # of unemployed +0 / Labour force + x
U-rate decrease

所以答案係undetermined
