    • ANALYSIS OF 6TH UKRAINIAN VERKHOVNA RADA STRUCTURE ON BASIS OF DEPUTIES ROLL-CALL VOTING

      The article presents the results of the application of mathematical methods to the analysis of the structure of legislative bodies (on the example of the 6th Ukrainian Verkhovna Rada). The study conducted by V.Oleynik is yet more proof of the efficiency of applying such methods to solving these problems. Building political maps and calculating consistency indices allowed the author to obtain the realistic picture of the distribution of power between the factions in the Ukrainian parliament in the period of 2007–2012. It has been demonstrated that the power of a faction (measured by Banzhaf index) is far from being determined by the proportion of seats it is entitled to; in fact, it may be zero for non-zero values of the proportion of seats. In turn, utilizing α-indexes enabled a more subtle analysis of power distribution, which clearly demonstrated that small factions might exert greater influence than large factions that hold extreme positions.
