This paper uses data from the universe of tax returns filed between 2001 and 2010 to test whether parents shift the timing of childbirth around the New Year to gain tax benefits. Filers have an incentive to shift births from early January into late December, through induction or cesarean...

The earned income tax credit generates large average tax refunds for low-income parents, and these refunds are distributed in a narrow time frame. I rely on this plausibly exogenous source of variation in liquidity to investigate the effect of cash on hand on unemployment duration. Among...

I analyze the optimal taxation of profits and labor income under endogenous firm formation. Individuals differ in their skill and cost of setting up a firm, and can become workers or entrepreneurs. A tax system in which profits and labor income are subject to the same schedule uses general...

I present a simple and tractable model of the optimal taxation of married couples, working off of the multidimensional screening framework of Armstrong and Rochet (1999). In particular, I study how the tax code varies with the degree of assortative mating. One result is that the "negative...

This paper uses the interwar United States as a laboratory for investigating the incentive effects of marginal income tax rates. We examine the impact of the large changes in rates in this period on taxable income using time-series/cross-section analysis of data by small slices of the income...

This paper employs an empirically estimated model to study the equilibrium effects of an increase in the US corporate average fuel economy (CAFE) standards. I identify and model heterogeneity across firms and find that the profit impacts of CAFE fall almost entirely on domestic producers. The...

Over three-quarters of US taxpayers receive income tax refunds, which are effectively zero-interest loans to the government. Previous explanations include precautionary and/or forced savings motives. I present evidence on a third explanation: inertia. I find that following a change in tax...

This paper derives optimal top tax rate formulas in a model where top earners respond to taxes through three channels: labor supply, tax avoidance, and compensation bargaining. The optimal top tax rate increases when there are zero-sum compensation-bargaining effects. We present empirical...

This paper provides evidence that dividend and capital gains tax rates importantly influence household portfolio choices. Using data from the Surveys of Consumer Finances around the 2003 dividend tax reductions, I estimate the relationship between taxes and household portfolio dividend yields. I...

We estimate the elasticity of corporate taxable income with respect to the statutory corporation tax rate using the population of UK corporation tax returns. We analyze bunching in the distribution of taxable income at kinks in the marginal rate schedule. We decompose this elasticity into an...
