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...

An important result due to Atkinson and Stiglitz (1976) is that differential commodity taxation is not optimal in the presence of an optimal nonlinear income tax (given weak separability of utility between labor and all consumption goods). This article demonstrates that their conclusion holds...

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...

We explore the interaction between two facts. The first is that income is variable; the second is that the tax and transfer system transforms before tax income into after tax income in highly non-linear ways. The effect is to penalize (and reward) income variability in a manner which is both...

In this paper, we examine Ricardian equivalence of debt and tax finance in a world in which taxes are not lump-sum but are levied on risky labor income. First, we show that the marginal propensity to consume out of a tax cut, coupled with a future income tax increase, is positive under...

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...

Relative to traditional piecewise linear income taxation schemes, it is possible to increase government revenues by offering to consumers a menu of linear income tax schedules. In the resulting Pareto-superior equilibrium, consumers sort themselves out according to their (unobservable)...

This paper reviews recent advances in the study of dynamic taxation, considering three main approaches: the dynamic Mirrlees, the parametric Ramsey, and the sufficient statistics approaches. In the first approach, agents' heterogeneous abilities to earn income are private information and evolve...

The first section of this paper introduces the topic. The next section shows that many parallel tax systems share common features and constructs a general model of the cost of capital based on the Hall-Jorgenson (1967) cost of capital formula. Section 3 presents conditions under which a parallel...

The evidence presented in this paper supports the basic theoretical presumption that state and local governments cannot redistribute income. Since individuals can avoid unfavorable taxes by migrating to jurisdictions that offer more favorable tax conditions, a relatively unfavorable tax will...
