In practice it is quite customary that an alternative is evaluated by means of n ≥ 2 grades x1, ..., xn, each of which taking an integer value from 1 («bad») to m ≥ 3 («perfect»). Thus, a problem arises to rank the set X of all n-dimensional vectors x with integer components from 1 to m....

The paper uses an experimental approach to study the voting power distribution in the context of classical model, as well as in generalized form which takes into account players’ preferences to coalesce with each other. Our results extend those of Montero, Sefton & Zhang (2008), confirming...

For a social decision problem we define a new aggregation procedure--the threshold rule--for the construction of an output ranking from the individual m-graded rankings with an arbitrary integer m >= 2. An axiomatic characterization of the procedure is given.

A simple measure of similarity for the construction of the market graph is proposed. The measure is based on the probability of the coincidence of the signs of the stock returns. This measure is robust, has a simple interpretation, is easy to calculate and can be used as measure of similarity...

The conventional approach to comparing tax progression (using local measures, global measures or dominance relations for first moment distribution functions) often lacks applicability to the real world: local measures of tax progression have the disadvantage of ignoring the income distribution...

Based on the earlier work of one of the authors, this paper develops a unified methodology to compare tax progression for dominance relations under different income distributions. We address it as uniform tax progression for different income distributions and present the respective approach for...
