This paper characterizes the optimal taxation of top earners in a world with externalities. It takes a reduced-form approach that spans a broad class of models where top earners create externalities on the economy. The model allows for a flexible relationship between top earnings and the...

We provide new evidence that cash transfers following the birth of a first child can have large and long-lasting effects on that child's outcomes. We take advantage of the January 1 birthdate cutoff for U.S. child-related tax benefits, which results in families of otherwise similar children...

Evidence that high tax rates significantly depress capital gains realizations is inconsistent with the implications of neoclassical investment models in unchanging economic environments. Higher tax rates reduce after-tax investment returns, thereby encouraging investors to sell capital assets...

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...

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...

Household time and money allocations in response to income support programs vary across diverse family circumstances and preferences, yet such heterogeneous responses are not well understood. Using data from a large-scale, multisite, U.S.-based randomized controlled study, we examine...

A key policy question in evaluating social programs to address childhood poverty is how families receiving unconditional financial support would spend those funds. Economists have limited empirical evidence on this topic in the U.S. We provide causal estimates of financial and time investments...

In this paper we develop a novel approach to measuring individual welfare within households, recognizing that individuals may have both different preferences (particularly regarding public consumption) and differential access to resources. We construct a money metric measure of welfare that...

This paper examines the multigenerational impact of children and whether the public provision of formal childcare lessens the earnings and employment impacts of children. We find that the arrival of a firstborn reduces employment and earnings of mothers and employment of grandmothers. Studying a...

Fiscal policy in the U.S. and other countries renders intertemporal budgets non-differentiable, nonconvex, and discontinuous. Consequently, assessing work and saving responses to policy requires global optimization. This paper develops the Global Life-Cycle Optimizer (GLO), a stochastic...
