Pré-publication, Document de travail: This paper examines wealth inequality dynamics in Chile from 2007 to 2021, focusing on two key macroeconomic events: the sharp rise in housing prices after the introduction of a real estate value-added tax in 2016 and the substantial liquidation of pension assets through early withdrawals during the pandemic. We introduce a methodological innovation that aims to improve the measurement of wealth inequality by integrating administrative pension fund records into household wealth surveys using machine learning techniques. Our results reveal extreme levels of wealth concentration, with the top 10% holding approximately two-thirds of national private wealth. However, inequality slightly declined over the period, particularly after 2016, as the outcome of two opposing forces: housing appreciation, which benefited middle-class households, and pension fund withdrawals, which disproportionately reduced wealth at the lower end of the distribution.
