Jakub Šedo - Roman Chytilek: How the Tailor of Marrakesh Suit Has Been Altered: Advantage Ratio as a Tool in Post-Communist Electoral Reforms Research

The text analyzes the character of the second reforms of electoral systems in post-communist countries. It describes the direction of the status quo change established after the first reform which was usually decided by participants with imperfect or incomplete information. We claim that the character of the second reforms favoured the bigger and established parties and accentuated the tendencies towards establishing electoral competition between political parties at the expense of involving other participants (independent candidates). We furthermore use a sample of 40 electoral events in 15 post-communist countries to analyze the potential of the strongest electoral parties and other parliamentary parties to transform votes into seats, and we connect this characteristic with the electoral changes made, arguing that the logic of electoral rules and the effects arising from actual vote shares sometimes reinforced themselves but – at least in some electoral events- run into opposite directions.
