AVAILABLE SOON: Wealth Tax and Information Disclosure Requirements, with Bertrand Garbinti, Mathilde Munoz, Stefanie Stantcheva and Gabriel Zucman

Abstract: Using exhaustive administrative wealth tax returns in France, we show that taxpayers do not respond to changes in wealth tax rates but strongly react to opportunities to hide information on the type of wealth they own. Combining a set of reforms that dramatically changed wealth information disclosure requirements with both dynamic bunching and difference-in-differences approaches, we estimate behavioral responses to information discontinuities in the wealth tax schedule. Implementing low information options in wealth tax returns causally decreased declared wealth growth rate by 0.4 percentage points each year on average, and by 4 percentage points for those taking-up the opportunity to hide wealth information after the reform. We build a theoretical framework that rationalizes the observed differences between individuals who self-select into the low-information option.

AVAILABLE SOON: Explaining Income and Wealth Inequality over the Long Run: The Case of France, with Stephane Auray, Aurelien Eyquem and Bertrand Garbinti

Abstract: We build an original model of heterogeneous agents with three assets (deposits, housing and equity), entrepreneurs, and a rich and realistic set of flat and progressive taxes and transfers. Using France as an illustration, our model reproduces the level and dynamics of wealth and income inequalities, the aggregate and distributional tax structure, the composition of wealth along the distribution as well as key macroeconomic aggregates over the 1984-2018 period. Counterfactual experiments shed light on the respective contributions of the different driving forces (changes in capital gains, taxation, markups, and others market forces) on inequality dynamics. When we neutralize the effects of changes in capital gains, taxation, and markups, income and wealth inequalities remain stable over the 1984-2019 period. While changes in markups are the main factor behind rising pretax income inequality, changes in capital gains, taxation, and markups all play a significant role in explaining wealth inequality dynamics.

REVISED 2022: Predistribution vs. Redistribution: Evidence from France and the U.S., with Antoine Bozio, Bertrand Garbinti, Malka Guillot, and Thomas Piketty, CEPR DP15415

Abstract: We construct series of post-tax income for France over the 1900-2018 period and compare them with U.S. series. We quantify the extent of redistribution and estimate the impact of redistribution vs pretax inequality on post-tax inequality. We obtain three major findings. First, redistribution has increased in both countries to reach similar levels today. Second, the long-run decline in post-tax inequality in France is due mostly to the fall in pretax inequality. Third, the relative lower post-tax inequality in France is entirely explained by differences in pretax inequality. This suggests that more attention should be paid to policies affecting pretax inequality. [Old 2018 WP]
