I propose and formalize an argument for why economists working in the welfarist normative tradition should include nonwelfarist principles in how they judge economic policy. The key idea behind this argument is that the world is too complex, and our ability to model it too limited, for us to...

This paper explores how the persistently popular "classical" logic of benefit-based taxation, in which an individual's benefit from public goods is tied to his or her income-earning ability, can be incorporated into modern optimal tax theory. If Lindahl's methods are applied to that view of...

U.S. survey respondents' views on distributive justice are shown to differ in two specific, related ways from what is conventionally assumed in modern optimal tax research. A large share of respondents, and in some cases a large majority, resist the full equalization of inequality due to brute...

This paper uses the neoclassical growth model to examine the extent to which a tax cut pays for itself through higher economic growth. The model yields simple expressions for the steady-state feedback effect of a tax cut. The feedback is surprisingly large: for standard parameter values, half of...

Should the income tax include a credit for short taxpayers and a surcharge for tall ones? The standard Utilitarian framework for tax analysis answers this question in the affirmative. Moreover, a plausible parameterization using data on height and wages implies a substantial height tax: a tall...

We examine a prominent justification for capital income taxation: goods preferred by those with high ability ought to be taxed. In an environment where commodity taxes are allowed to be nonlinear functions of income and consumption, we derive an analytical expression that reveals the forces...

This paper examines the optimal response of monetary and fiscal policy to a decline in aggregate demand. The theoretical framework is a two-period general equilibrium model in which prices are sticky in the short run and flexible in the long run. Policy is evaluated by how well it raises the...

Empirical research suggests that parents' economic resources affect their children's future earnings abilities. Optimal tax policy therefore treats future ability distributions as endogenous to current taxes. We model this endogeneity, calibrate the model to match estimates of the...

The workhorse model of optimal taxation strongly recommends tagging, but its use in policy is limited. I argue that this puzzle is a symptom of a more fundamental problem. Conventional theory neglects the diverse normative criteria with which, as extensive evidence has shown, most people...

We highlight and explain eight lessons from optimal tax theory and compare them to the last few decades of OECD tax policy. As recommended by theory, top marginal income tax rates have declined, marginal income tax schedules have flattened, redistribution has risen with income inequality, and...
