1. Which of the following implies an increase in the unemployment rate?
A. The labour force increases at a higher rate than the employed population.
B. The labour force decreases at a higher rate than then unemployed population.
C. Both the employed population and the labour force decrease.
D. Both the unemployed population and the labour force increase.

C&D由於唔知個%change,所以錯啦
我本人既答案係B.
因為分母(labour force)跌得快過個分子(unemployed population), 出黎個結果係會大左架嘛.咁B咪岩囉.?
但係老師話個答案係A...
求解答

結果係Cancel左呢條題目 因為A & B都岩...
不過好似話A係better option, 不過要解B無咁好都有一定難度

unemployed population跌緊,employed population即係升緊?
咁上面升,下面跌,employment rate係升的,所以unemployment rate係跌

第二個approach,唔做野嘅人多過失業嘅人(唔係econ term用解,只照字面解),咁unemployment rate自然係跌

你睇多次條問題
1. Which of the following implies an increase in the unemployment rate?
A. The labour force increases at a higher rate than the employed population.
B. The labour force decreases at a higher rate than then unemployed population.

事先我地需要知道條 Formula
Unemployment Rate = (Number of Unemployed / Total Labor Force) * 100%

而家就咁 plug in 數字入去,
事實上當 A 個答案出黎大過 B, 已經知道邊個非就業問題係嚴重, 亦即所謂 increase ~

e.g.

ORIGINAL
Unemployed people = 30,000
Employed people = 70,000
Total Labor Force = 100,000


你答 B 係未 >
Labour Force Decrease at a HIGHER RATE than Unemployed Population > 即係其實兩個都有趺, 一個趺得多 D, 一個趺得小 D 姐 ~ 係未 ?
e.g.
Unemployed People = 30,000 > Decrease 5 % = 50,000 * 0.95 = 28,500
Labour Force = 100,000 > Decrease 10% = 100,000 * 0.90 = 90,000

According the formula = 28,500 / 90,000 = 31.67% > 呢個就會係你 B 個答案 ~

到你 miss 話 A > The labour force increases at a higher rate than the employed population.
Labour Force Increase at a HIGHER RATE than Unemployed Population

用返上面例子
e.g.
Unemployed people = 30,000 > 暫時未知
Employed people = 70,000 > + 5% = 73,500
Total Labor Force = 100,000 > + 10% = 110,000

Unemployed people = 110,000 - 73,500 = 36,500

According the formula: 36,500 / 110,000 = 33.18% (我地係要用 number of Unemployed 去計 Unemployment Rate) ~

A 就係 33.18%, B 就係 31.67% ~
明顯地 A 個數係大過 B 個數, 所以 A 個 Unemployment Rate 係較為嚴重 ~

如果有錯請指 ~

Assume that employment rate = a/b, where a = employed population and b = labor force,

If % increase in labor force > % increase in employed population,

The new employment rate = a(1+c%)/b(1+d%) that 1+c% < 1+d%

In this way, new employment rate will be lower than original rate

For answer B,
It is true.

By the same approach, you can find out there will be increase in unemployment rate. The situation it describes is that some employed people and a few umployed people have left labor force but there are Only a few unemployed people, if not none, replace people who are initially employed.
