The Internal Revenue Code of the U.S. as well as income tax statutes in a number of states contain provisions that penalize some married couples by virtue of their marital status. These families have greater tax liabilities than would apply if the husband and wife divorced. At the same time,...

Using decomposable measures of inequality, the implications of household structure are investigated by examining inequality between and within household groups based on the number of exemptions, which correlates with household size, and the filing status, which correlates with the common forms...

New measures of the degree of overall income tax progression in the United States are provided for the period 1969 to 1995. Indices of progression from the distributional and tax scale invariant classes of measures are considered. The sensitivity of measures of progression to the income concept...

Confronted with rising poverty after an economic crisis in 1995, the Government of Mexico changed its social policy. It terminated universal subsidies for tortilla and funded new investments in human capital through PROGRESA, an innovative program providing school stipends to poor children as...

The distributional impacts of replacing an income tax that has graduated marginal rates by a flat tax are complex. Typically the flat tax rate will be less than the top marginal rate under the pre-existing tax, leading to gains for the wealthiest. On the other hand, real-world proposals...

Ranking groups (schools, regions, counties) according to the average score of their constituent parts – say, ranking schools by the academic achievements of students – is a common yardstick in evaluation and a cornerstone of any planning process. In this paper we show that under certain...

The last 20 years have seen a significant evolution in the literature on horizontal inequity (HI) and have generated two major and “rival” methodological strands, namely, classical HI and reranking. We propose in this paper a class of ethically flexible tools that integrate these two...

Some personal income tax breaks reward socially approved activities, others serve the interests of tax administrators and special interest groups. All give rise to classical HI. We allow for the categorization of tax breaks into deserving and undeserving types, and pose a “modified HE”...

The paper proposes an alternative way of defining tax progressivity, one in which it becomes a function of marginal, not average tax rates. Changes in Tax Progressivity are then related to modifications in the distribution of pre-tax incomes or to variations in marginal rates. Using Israel’s...

This paper examines the question of the extent to which redistribution can be achieved using a structure of consumption taxes with differential rates and exemptions. A local measure of progression, that of liability progression (equivalent to the revenue elasticity) is examined. Results are...
