中文摘要
本文考察了2007年至2021年间智利财富不平等的水平与动态, 彼时智利私人养老金体系为强制性, 政府住房政策则以私人产权为核心。我们聚焦两大重大宏观经济事件:2016年对新建住宅征收增值税后住房价格的急剧上涨, 以及近期疫情期间通过提前提取养老金实现的大规模养老金资产清算。为此, 我们拓展现有方法, 运用机器学习技术将行政记录中的养老基金余额整合进家庭财富调查, 从而构建微观—宏观一致的财富分布。结果显示, 财富呈现出显著的集中态势:最富有的1%人群持有约三分之一的私人财富总额——这一水平与美国相当——主要由其对金融资产的不成比例持有所驱动。相比之下, 最底层50%人群持有7%至9%的财富, 主要以住房和养老金资产的形式持有, 这一份额高于大多数欧洲国家所报告的水平。我们还发现, 该时期财富不平等有小幅下降, 尤其是在2016年之后。反事实分析表明, 这一下降反映了两种相反力量的相互作用:住房升值主要惠及底层90%的家庭, 而养老金提取则在降低整个分布中各群体财富水平的同时, 相对加剧了不平等。我们关于水平、趋势与反事实情形的研究发现, 在不同的方法设定下均保持稳健。
Abstract
This paper examines the levels and dynamics of wealth inequality in Chile between 2007 and 2021, in a context where the private pension system is mandatory and government housing policies are centered on private ownership. We focus on two major macroeconomic events: the sharp increase in housing prices following the introduction of a value-added tax on new dwellings in 2016 and the large-scale liquidation of pension assets through early withdrawals during the recent pandemic. To do so, we construct a micro–macro consistent wealth distribution by extending existing methodologies to integrate administrative pension fund balances into household wealth surveys using machine learning techniques. Our results reveal pronounced wealth concentration: the top 1% hold roughly one-third of total private wealth—levels comparable to those observed in the United States—driven by their disproportionate ownership of financial assets. By contrast, the bottom 50% hold 7–9%, primarily through housing and pension assets, shares that exceed those reported in most European countries. We also document a modest decline in wealth inequality over the period, particularly after 2016. A counterfactual analysis suggests that this decline reflects the interaction of two opposing forces: housing appreciation, which predominantly benefited the bottom 90% of households, and pension withdrawals, which reduced wealth across the distribution while relatively increasing inequality. Our findings on levels, trends, and counterfactuals are robust across alternative methodological specifications.
