Global Inequality Dynamics: New Findings from WID.world
基于WID.world数据，研究了美国、中国、法国和英国的不平等趋势，发现各国顶层收入与财富份额普遍上升但幅度差异大，强调政策与制度的影响，并呼吁提高数据透明度。
This paper presents new findings on global inequality dynamics from the World Wealth and Income Database (WID.world), with particular emphasis on the contrast between the trends observed in the United States, China, France, and the United Kingdom. We observe rising top income and wealth shares in nearly all countries in recent decades. But the magnitude of the increase varies substantially, thereby suggesting that different country-specific policies and institutions matter considerably. Long-run wealth inequality dynamics appear to be highly unstable. We stress the need for more democratic transparency on income and wealth dynamics and better access to administrative and financial data.
