In cross-sectional studies, countries with greater income inequality typically exhibit less support for government-led redistribution and greater acceptance of wage inequality (e.g., United States versus Western Europe). If individual nations evolve along this pattern, a vicious cycle could form...

We estimate growth rates of real incomes in the U.S. by quintiles using the Congressional Budget Office's (CBO) post-tax, post-transfer data as basis for the period 1979-2011. We improve upon them by including only the present value of earnings that will accrue in retirement and excluding items...

Horizontal equity -- the command that equals be treated equally -- has received increased attention, particularly in attempts to measure the desirability of tax reform proposals. This paper questions whether the normative foundations for horizontal equity justify the indexes and approaches that...

Anti-utilitarian norms often are used in assessing tax systems. Two motivations support this practice. First, many believe utilitarianism to be insufficiently egalitarian. Second, utilitarianism does not give independent weight to other equitable principles, notably concerns that reforms may...

Alan Auerbach and Kevin Hassett offer a new measure of horizontal equity (HE) that is designed to overcome deficiencies in prior indexes. There is, however, a fundamental problem that their effort shares with their predecessors' attempts: the underlying rationale for pursuing HE at the expense...

Much criticism of the income tax involves administration: the enormous complexity of the system is responsible for large compliance costs, public and private, and the tax gap is large despite substantial resources devoted to enforcement. The desire for simplification and improved compliance...

Attempting to shed light on the optimal size of government, economists have analyzed planning problems that specify a set of feasible taxation-spending policies and a social welfare function. The analysis characterizes the optimal policy choice of a planner who knows the welfare achieved by each...

This paper proposes a new way to evaluate tax reforms, by aggregating losses and gains of different individuals using “generalized social marginal welfare weights.” A tax system is optimal if no budget neutral small reform can increase the weighted sum of (money metric) gains and losses...
