那麼,這篇文章一定十分適合你。

今天學博小編為大家整理了DSE常見的elasticity題型,還會附上相應的答題flow及例題,希望能幫助到大家。

Type 1: Ordinary elasticity

答題flow

-If the demand for _____ is elastic/inelastic,

-the % increase/decrease in P will be smaller/higher than the % decrease/increase in quantity (demanded).

例題

2013/DSE/II/9(a)

The following is an extract from a local newspaper article.

The MTR corporation raised the railway fares by 5.4% in 2012. This increase was based on the Fare Adjustment Mechanism set by the government. To respond to the discontent of the public over the fare increase, the Corporation introduced a concessionary measure ‘’Ride 10 Get 1 Free’’.

With the aid of a diagram, explain under what condition the total expenditure of passengers on the MTR will increase because of the rise in fare.                 (5 marks)

Marking scheme

elasticity dse

Indicate in diagram

-correction position of gain and loss (1)

-gain>loss (1)

Verbal elaboration

If the demand for MTR service is inelastic, (1)

the % increase in fare will be higher than the percentage decrease in the number of trips, (so the total expenditure will increase). (2)

elasticity dse

Indicate in diagram

-supply curve shifts to the left (1)

-Q drops and P increases (1)

Advertisements

-loss in total revenue<gain in total revenue (2)

Verbal elaboration

The % decrease in quantity (demanded) is smaller than the % increase in price. (1)

例題

2018/DSE/II/5(a)

During peak flu seasons, there is not enough medical staff in public hospitals in Hong Kong.

An economist stated, ‘Even if the government sharply increases the wage rates of the medical staff, it is still difficult to relieve the problem.’ Justify this statement using the concept of elasticity of supply/demand.                                                                                                                          (3 marks)

Marking scheme

The supply of medical staff may be inelastic because (1)

They require special training and qualification. (1)

(Even if the government raises their wage rates sharply,) the % increase in the quantity supplied would still be smaller than the % increase in their wage rates. (1)
