The global concentration of wealth
比较了相对与绝对财富集中度的历史变化，发现相对集中度虽上升但非历史最高，而绝对集中度可能创历史新高，高净值人群在2008年金融危机后迅速恢复，2013年财富比2007年至少高30%。
This paper compares changes in relative and absolute wealth concentrations to establish whether both processes have followed similar trajectories. The findings indicate that while the relative wealth concentration level has increased in recent times, it is not extraordinarily high from a historical perspective. In contrast, the absolute wealth concentration level is most likely higher than has ever previously occurred, due to the growth of per capita wealth holdings and the population size of high net worth individuals (HNWIs). The available data also suggest that HNWIs recovered very quickly from the losses that they experienced in the financial crisis of 2008. As a result, HNWIs’ wealth holdings in 2013 were at least 30% higher than they were in 2007. The post-crisis recovery of billionaires was even stronger, with their 2014 net wealth holdings more than 85% higher than 2007 levels.
