A. Unemployment benefits increase
B. Tax system becomes more regressive
C. Tax system becomes more progressive
D. Healthcare subsidised by the government
参考答案: B
本题详细解析:
Shifting of the Lorenz curve from X to Y increases inequality.
In a rezf(.j(a 6dg)cf* btehgressive taxation system, the fraction of income paid as tax increases with the decrease in income. Hence, if the tax system becomes more regressive, the burden on the poor increases, which increases inequality. Hence, the Lorenz curve (ha .*fc(b zt)jed6gfshifts away from the line of equality.
Options A, C, and D result in more equal incomes and shift the Lorenz curve closer to the line of equality:
Option A: as increasing unemployment benefits raises the incomes of low-income people thereby reducing inequality.
Option C: as progressive tax systems tax the rich at a higher rate, leading to a reduction in inequality.
Option D: as healthcare, if subsidised by the government, will become more affordable for the poor (increasing human capital) which will reduce inequality.
