(4 marks) (Sample paper Q2)

2. Under the School Textbook Assistance Scheme (STAS), needy students are granted subsidies to
cover the costs of textbooks and miscellaneous school-related expenses. Explain how STAS can
enhance equity in Hong Kong society.
(4 marks) (PP Q11d)
- The STAS increases the income of the needy students’ families while the rich families cannot enjoy this benefit.
− The STAS will help equalize opportunities as it helps the needy students further their studies.
− Education can increase future income of the needy students so it may help narrow the income gap over time.
− Any other relevant point (2@; max: 4)
3. According to the report of the United States in 2008, the Gini coefficient of Hong
Kong and Beijing were 0.53 and 0.22 respectively.
(a) Was the income gap between the rich and the poor in Hong Kong wider or
narrower than that in Beijing? (1 mark)
(b) Explain how an increase in the standard tax rate of salaries tax will affect
the post-tax Gini coefficient of Hong Kong. (3 marks) (2012 Q4)
(a) Wider (1)(b) Lower, because (1)
higher income group has a lower post-tax income while the income of lower income group remains unchanged. (2)
4. In 2011, the Financial Secretary announced the “Scheme $6000” which provides to each Hong
Kong permanent resident who is 18 years old or above.
(b) Do you think that the government should introduce the “Scheme $6000” to improve equity in
the Hong Kong society? Explain.
(4 marks) (2012 Q10b)
- Equity is a subjective concept that involves value judgements / different people use different standards of equity (1)
- Yes, because the $6000 results in a higher percentage increase in income of the poor. (2)
- No, as it does not help equalize opportunities. Relative to the rich, the poor do not get more resources to improve their productivity / increase future income. (2)
- No, it is not equalizing outcome as not everyone can benefit from the scheme, e.g. non-permanent residents and residents who are below 18 years old are not eligible for the $6000. (2) (max: 4)

5.
(a) Construction, since the Gini coefficient is lower. (1)
Reasons:
1. The entry to a particular occupation is closely associated with a person’s
human capital, which tends to be more homogeneous among the construction
workers than among finance professionals. (2)
2. The construction industry often pays their workers by times rates, which are
more or less uniform across workers. In addition to basic salaries,
compensions to the employees of financing, insurance, real estate and
business services often include performance-based commissions, bonuses
and profit-sharing, which may result in a greater diversity of income within
this industry. (2) (max: 3)
(b) How may the data given in Table 1 and 2 help explain the change in the income
inequality of Hong Kong as reflected in Table 3? (4 marks) (2013 Q7)
The Gini coefficient, which reflects the degree of income inequality, has increased in
the HK economy as a whole. (1)
Possible reasons:
- As shown in Table 1, income inequality in both the construction and financing,
insurance, real estate and business services industries has increased. Other things
being equal, this would contribute to the increase in the income inequality in the entire
economy. (2)
F.5_Efficiency, Equity and the Role of Government_Past Papers 8
- As shown in Table 2, there is an increase in the proportion of working population in
the industry with a larger disparity of income (i.e. financing, insurance, real estate and
business services) and a decrease in the industry with a smaller disparity of income
(i.e. construction). Other things being equal, this changing pattern of employment
distribution across the two industries would contribute to the increase in the income
inequality in the entire economy. (2) (max: 3)
6. The government has launched the “Work Incentive Transport Subsidy Scheme”…
(b) Discuss the effects of the scheme on
(ii) income inequality (3 marks) (2013 Q11)
It helps to reduce the income inequality. It helps to equalize outcome as it provides
extra money for the lower-income group only./ It increases their opportunity of
finding a job with higher income because they can travel farther away from their
residential area. (3)
7. Figure 1 shows the market supply and demand curves of Good X. Suppose the
government raises the price floor from Pa to Pb.
With the aid of Figure 1, explain whether the rise in the price floor could
enhance efficiency. (6 marks) (2014 Q3)
