This paper investigates whether taxpayers bunch at the kink points of the US income tax schedule (i.e. where marginal rates jump) using tax returns data. Clear evidence of bunching is found only at the first kink point (where marginal rates jump from 0 to 15%). Evidence for other kink points is...

We characterize optimal policies in a multidimensional nonlinear taxation model with bunching. We develop an empirically relevant model with cognitive and manual skills, firm heterogeneity, and labor market sorting. The analysis of optimal policy is based on two main results. We first derive an...

We study optimal taxation in a model with endogenous financial frictions, risky investment and occupational choice, where the distribution of wealth across entrepreneurs affects how efficiently capital is used. The planner chooses linear taxes on wealth, capital and labor income to maximize the...

Robust support for corporate income taxation is a puzzle for standard tax theory because the tax's incidence is uncertain and unreliable. We propose a resolution: if the corporate tax is seen as a benefit-based tax, its normative appeal depends on the correspondence between its incidence and...

This paper provides general and empirically implementable sufficient statistics formulas for optimal nonlinear tax systems in the presence of preference heterogeneity. We study unrestricted tax systems on income and savings (or other commodities) that implement the optimal direct-revelation...

This paper derives analytical measures of the combined effects of tax changes and adjustment costs on investment and market value. Unlike earlier measures, the effective tax rate derived is valid in the presence of adjustment costs and anticipated tax changes. The derived measure of the impact...

The Economic Recovery Tax Act of 1981 mandated a series of tax rate reductions for the period 1982-1984. They represented the most significant changes in the tax rate structure in nearly two decades. This paper considers the response of taxpayers to these cuts and extends these results to...

This paper deals with the international effects of budget deficits arising from distortionary tax and transfer policies. The analysis demonstrates that the consequences of tax policies and the characteristics of the international transmission mechanism depend critically on the precise...

This paper encompasses multiple sources of inefficiency introduced by the U.S. tax system into a single general equilibrium model. Using disaggregate calculations of user cost, we measure interasset distortions from the differential taxation of many types of assets. Simultaneously, we model the...

An important proposition in the theory of efficient taxation is that, if capital income is taxed, all types of capital income should be taxed at the same rate. This conclusion has motivated extensive empirical analysis of the tax rates on different types of capital income. It has also been the...
