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...

This paper analyzes the distortions created by taxation and the features of tax systems that minimize such distortions (subject to achieving other government objectives). It starts with a review of the theory and practice of deadweight loss measurement, followed by characterizations of optimal...

This paper analyzes the optimal treatment of tax expenditures. It develops an optimal tax model where individuals derive utility from spending on a contribution' good such as charitable giving. The contribution good has also a public good effect on all individuals in the economy. The government...

This paper revisits the Atkinson-Stiglitz result on uselessness of commodity taxation in the presence of optimal non-linear income taxation in a more general setup, namely when tastes are heterogeneous. This general analysis displays the key economic assumptions under which the Atkinson-Stiglitz...

The strength of the behavioral response to a tax rate change depends on the environment individuals operate in, and may be manipulated by instruments controlled by the government. We first derive a measure of the social benefit to affecting this elasticity. The paper then examines this effect in...

This paper derives optimal income tax formulas using compensated and uncompensated elasticities of earnings with respect to tax rates. A simple formula for the high income optimal tax rate is obtained as a function of these elasticities and the thickness of the top tail of the income...

A central tax policy parameter that has recently received much attention, but about which there is substantial uncertainty, is the overall elasticity of taxable income. We provide new estimates of this elasticity which address identification problems with previous work, by exploiting a long...

The effects of income and consumption taxation are examined in the context of models in which the growth process is driven by the accumulation of human and physical capital. The different channels through which these taxes affect economic growth are discussed, and it is shown that in general the...

The complexity of the income tax is an unending source of complaint. Compliance costs have received increasing attention and are estimated to be large. Yet most recognize that some degree of complexity is necessary if ability to pay is to be measured accurately. This article presents a framework...
