The share of pre-tax income flowing to the top of the UK income distribution increased continually and substantially in the three decades leading up to the financial crisis, but has changed little since 2013. Using microdata sampled from UK tax records, we describe the nature of top incomes in...

We study the persistent effects of temporary changes in U.S. federal corporate and personal income tax rates using a narrative identification approach. A corporate income tax cut leads to a sustained increase in GDP and productivity, with peak effects between five and eight years. R&D spending...

We evaluate the 2017 Tax Cuts and Jobs Act. Combining reduced-form estimates from tax data with a global investment model, we estimate responses, identify parameters, and conduct counterfactuals. Domestic investment of firms with the mean tax change increases 20% versus a no-change baseline. Due...

Most antipoverty policy in the United States focuses on families with children, but efforts to assist childless adults have gained traction in recent years. We examine the impact of the Earned Income Tax Credit on the labor force outcomes of childless adults using the age-25 eligibility...

The philanthropic sector is highly consequential, particularly in the United States, and the most important policies directed toward this sector are tax policies. Yet most economic analysis of the optimal tax treatment of charitable giving is ad hoc, treating it as a subject unto itself. This...

This paper rethinks the design of the income tax by assuming that the objective of the tax is not to redistribute from rich to poor but instead to provide some insurance to individuals against the uncertainties they face in their future earnings, a motivation for the tax proposed in Buchanan...

Although it is generally blind with respect to race, the federal individual income tax can create racial disparities when factors that affect tax liability are associated with race. We provide new evidence on racial differences in marriage penalties and bonuses in the income tax, using data from...

This paper studies how differences in labor market regulations shape countries' comparative advantage in the cross-border provision of labor-intensive services, using administrative data in Europe for the last two decades. I exploit exogenous variation in labor taxes and minimum wages faced by...

The two main workhorses of state tax systems are levies on sales and individual incomes. In this paper we develop and implement a coherent methodology for characterizing these systems. The measures thus generated are used to show how the various systems differ across states, and how they evolved...

We assess the Covid-19 pandemic's implications for state government sales and income tax revenues. We estimate that the economic declines implied by recent forecasts from the Congressional Budget Office will lead to a shortfall of roughly $106 billion in states' sales and income tax revenues for...
