This paper critically surveys the large and growing literature estimating the elasticity of taxable income with respect to marginal tax rates (ETI) using tax return data. First, we provide a theoretical framework showing under what assumptions this elasticity can be used as a sufficient...

We develop an optimal tax framework that combines two recent extensions of tax analysis: a tax-systems emphasis on non-rate policy instruments, and a recognition of the role of behavioral biases. Although the implications of taxpayers' biases for optimal tax rates have received considerable...

This paper develops a methodology in integrating the information from a micro-unit data file of tax returns into the framework of a general equilibrium model of taxation with endogenous financial behavior. It discusses how the available information on capital income flows can be used to impute...

This paper applies a numerical optimization technique using microunit tax data to the problem of choosing the parameters of a flat-rate tax system, should one be desired. Our approach is to first formulate explicit objectives that a flat-rate tax might reasonably be designed to meet, such as...

The current economic crisis requires fast information to predict economic behavior early, which is difficult at times of structural changes. This paper suggests an innovative new method of using data on internet activity for that purpose. It demonstrates strong correlations between keyword...

This paper takes stock of what is known about the efficacy of actual Value Added Tax (VAT) systems, nearly 100 years since the tax was conceived. Existing VAT systems fall short of the idealized version on many dimensions, some by design and others unintended. Actual VATs might therefore have...

In the aftermath of the recent financial crisis, a variety of taxes on financial institutions have been proposed or enacted. These taxes' justifications range from punishing those deemed to have caused or unduly profited from the crisis, to addressing the budgetary costs of the crisis, to better...
