Tytuł:: Degressive proportionality – notes on the ambiguity of the concept
Autorzy:: Dniestrzański, Piotr
Powiązania:: https://bibliotekanauki.pl/articles/584986.pdf
Data publikacji:: 2013
Wydawca:: Wydawnictwo Uniwersytetu Ekonomicznego we Wrocławiu
Tematy:: degressive proportionality
apportionment problem
European Parliament
Opis:: This article discusses the problem of the definition of degressive proportionality. This term is used in many areas of economics but its meaning is not standardized. It is understood differently when related to tax issues compared to distribution of seats in the European Parliament. The differences are small but significant. The article provides and analyzes the different meanings of the concept of degressive proportionality and proposes to introduce two new concepts – concave degressive proportionality and convex degressive proportionality.

Parliamentary system
Opis:: The problem of allocating seats in the European Parliament among EU member states is still open. The principle of degressive proportionality which is incorporated into the Lisbon Treaty offers so much room to maneuver, that it decides on how the composition of the European Parliament during subsequent terms only to a certain extent. This paper examines the principle of degressive proportionality, showing how from the mathematical point of view it is located between equal and proportional division. The paper suggests, furthermore, a way of measuring to what extent the division of seats is equal and to which proportional. The analysis carried out in the context of the Cambridge Compromise, where a group of mathematicians (invited by Parliament) has submitted a proposal for a long-term solution to the problem of allocation of mandates.

Tytuł:: The Gini coefficient as a measure of disproportionality
Autorzy:: Dniestrzański, Piotr
Powiązania:: https://bibliotekanauki.pl/articles/421256.pdf
Data publikacji:: 2015
Wydawca:: Wydawnictwo Uniwersytetu Ekonomicznego we Wrocławiu
Tematy:: inequality measure
the Gini coefficient
mathematics teaching
Opis:: Measures of inequality, properly adapted, often tend to be used as a tool to address the issue of disproportionality. The most popular of them, such as the Gini or Atkinson coefficient, or entropy coefficient can, under certain circumstances, act as measures of disproportionality. However, one must specify precisely what is to be measured and interpret the results consistently. In this paper we analyze what confusion or outright errors can be committed when using inequality coefficients. The presented analysis is aimed at the Gini coefficient, however, the problem also applies to the rest of the coefficients.

Tytuł:: Axiomatization of divisor methods and weakly degressive proportionality
Autorzy:: Dniestrzański, Piotr
Powiązania:: https://bibliotekanauki.pl/articles/421295.pdf
Data publikacji:: 2017
Wydawca:: Wydawnictwo Uniwersytetu Ekonomicznego we Wrocławiu
Tematy:: degressive proportionality
fair division
axiomatization of divisor methods
Opis:: The paper analyzes the differences between weakly degressive proportionality and proportional allocations represented by divisor methods. The analysis is accomplished by the axiomatization of divisor methods in line with Balinski and Young.
