Wealth Inequality in Sweden: What can we Learn from Capitalized Income Tax Data?
利用2000-2012年瑞典财富登记和资本化收入税数据，研究发现2007年后财富不平等加剧，银行资产和住房分布不均为主要驱动因素，并评估了资本化方法的可靠性。
This paper presents new estimates of wealth inequality in Sweden during 2000–2012, linking wealth register data up to 2007 and individually capitalized wealth based on income and property tax registers for the period thereafter when a repeal of the wealth tax stopped the collection of individual wealth statistics. We find that wealth inequality increased after 2007 and that more unequal bank holdings and housing appear to be important drivers. We also evaluate the performance of the capitalization method by contrasting its estimates and their dispersion with observed stocks in register data up to 2007. The goodness‐of‐fit varies tremendously across assets and we conclude that although capitalized wealth estimates may well approximate overall inequality levels and trends, they are highly sensitive to assumptions and the quality of the underlying data sources.
