This paper aims to assess the extent to which top earners in Ecuador were affected by the COVID-19 crisis compared to other segments of the population. Our analysis uses administrative data for individuals affiliated to social security between January 2019 and December 2021. We identify the top...

This paper presents the properties of optimal piecewise linear income tax systems for families based on joint and individual incomes respectively. It models the interaction between the wage rates of mothers as "second earners" and variation in child care prices and productivities as determinants...

This paper analyses optimal piecewise linear tax systems for two-earner households, based on joint and individual incomes respectively. It models the interaction between wage rates and variation in child care prices and productivities as determinants of across-household heterogeneity in second...

In this paper, we analyze how top income earners (TIEs) respond to changes in personalincome taxation. Our identification strategy exploits a unique reform to Uruguay’s progressivelabor income tax schedule that affected differently the tax rates of taxpayers within the top 1%of the labor...

Using unique longitudinal administrative tax panel data for the District of Columbia (DC), we assess the combined effect of the DC supplemental earned income tax credit (EITC) and the federal EITC on poverty and income dynamics within Washington, DC, from 2001 to 2011. The EITC in DC merits...

While policymakers are rightly concerned about evidence of rising income concentration at the top, it is often wrongly assumed that the same rich individuals stay rich. In reality, the membership of this group are in a state of constant flux. This new study, based on more than 20 million tax...

We analyze the macroeconomic implications of increasing the top marginal income tax rate using a dynamic general equilibrium framework with heterogeneous agents and a fiscal structure resembling the actual U.S. tax system. The wealth and income distributions generated by our model replicate the...

This paper assesses the feasibility of simulating the distributional impacts produced by various tax and transfer instruments in Viet Nam. Viet Nam's system of tax and transfer policies underwent frequent changes, in terms of diversity and adjustment scope. The most important source of data is...

We derive an ex post neutral comprehensive income tax on pension schemes equivalent to a Johansson-Samuelson tax that guarantees non-discriminatory treatment of lifetime-dependent and other investments. By separately taxing contributions and benefits, our concept does not require any assumptions...
