In empirical analysis, the Kakwani index is the most frequently used indicator for comparing progressivity across countries and over time. The Kakwani is often assumed to measure to what extent a policy design is targeted to the poor. It has, however, a major drawback: it is not defined for net...

Is the Spanish economy positioned at its optimal progressivity level in personal income tax? This article quantifies the aggregate, distributional, and welfare consequences of moving toward such an optimal level. A heterogeneous households general equilibrium model featuring both life cycle and...

We propose a general class of indices of horizontal inequity that complements existing classes of progressivity and vertical equity indices. The class of horizontal inequity indices can also correct for biases in measuring a general class of inequality measures. We illustrate our results using...

In a homogeneous framework where individuals can only be distinguished on the basis of their incomes, we examine the incidence of taxation on the amount of deprivation felt in the society. We conceive deprivation in terms of utility or well-being rather than just in terms of income and we...

The German tax system is usually considered as one of the most progressive ones in Europe, especially due to its unique mathematical formula of continuously increasing marginal tax rates in the personal income tax. However, other taxes such as indirect or payroll taxes need to be considered as...
