Despite South Africa’s need for inclusive economic growth, we find that the top income percentiles continue to diverge from the rest of the income distribution. We compare household survey data and tax data (which, unlike household survey data, includes accurate data for the very rich) to investigate the patterns of income growth over the period 2003 to 2018. We find that the gap between the stagnant middle and the top end of the income distribution widened, particularly over the post-recession period. We also show that the divergence was partly driven by high returns to capital for those with top incomes.

独家增长？在南非国家经济增长缓慢的情况下，最高收入快速增长

尽管南非需要包容性经济增长，但我们发现最高收入百分位数继续与其他收入分配不同。我们通过比较住户调查数据和税收数据（与住户调查数据不同，包括针对非常富有的人的准确数据）来调查 2003 年至 2018 年期间的收入增长模式。收入分配的末期扩大了，特别是在后衰退时期。我们还表明，这种差异部分是由高收入者的高资本回报驱动的。
