Top Income Adjustments and Inequality: An Investigation of the EU‐SILC†
研究了世界不平等数据库的高收入调整方法对欧盟26国2003-2017年收入不平等的影响，发现基尼系数平均上升约2.4点，但各国差异显著，且对趋势影响有限。
This paper provides a novel assessment of how the World Inequality Database (WID) top income adjustment applied by Blanchet, Chancel, and Gethin (2021) to European Union Statistics on Income and Living Conditions (EU‐SILC) data for 26 countries over 2003–2017 for Distributional National Accounts purposes affects inequality in equivalized gross and disposable household income. On average, the Gini is increased by around 2.4 points for both gross and disposable income, with notable differences across countries but limited impact on trends. EU‐SILC countries that rely on administrative register data see relatively small effects on inequality. Comparing with two other recent studies, differences in impacts on measured inequality depend less on the adjustment method and more on whether external data sources are used.
