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...

Knowing the elasticity of taxable income (ETI) is crucial for understanding the effects of taxation on taxpayer behavior and consequently on tax revenues. Previous research finds that high-income individuals are the most sensitive to tax policy changes. However, these individuals have more...

This paper studies how the transition from self-employment to employee-jobs over the long run of development explains growth in income tax capacity. I construct a new database which covers 100 household surveys across countries at different income levels and 140 years of historical data within...

How are optimal taxes affected by the presence of superstar phenomena at the top of the earnings distribution? To answer this question, we extend the Mirrlees model to incorporate an assignment problem in the labor market that generates superstar effects. Perhaps surprisingly, rather than...

The resource cost of operating the income tax system is large, totaling as much as seven to eight percent of revenue raised. One source of this cost is the system of itemized deductions, which can require extensive record keeping and calculation. This paper estimates the resource cost of...

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...

When will the optimal mix of a constant income tax with a constant consumption tax involve a positive income tax? The assumptions of the model in which this question is asked include (1) identical individuals with coincident lifetimes who work in every period; (2) initial endowments of physical...

The purpose of the present note is to explore the structure of optimal income taxation/redistribution in an economy where the welfare of individuals depends in part on relative after-tax consumption, i.e., we specify individual welfare as a function of absolute and relative after-tax...
