Master's Degree final paper work "Electoral systems impact on voting results: 2004 and 2008 Lithuanian parliament elections' case study" pays main attention to what the results would be of the two last elections to Lithuanian parliament if other than parallel electoral system was used. Main goal is to analize and experimentaly check how do different electoral systems impact Lithuanian parliament results and how depending on results do the party position, weight and influence change. Object: 1. To review electoral systems currently used in the world; 2. To make detailed analysis of main electoral systems stressing their advantages and disadvantages; 3. To analyse 2004 and 2008 Lithuanian parliament elections using five different electoral systems (party list, two round, first-past-the-post, MMP and limited voting); 4. To compare possible results of 20004 and 2008 Lithuanian parliament elections using different electoral systems and conclude the results Hypothesis: 1. Party list system provides new parties with additional seats in the parliament; 2. Plurality / majority systems provides new parties with less seats comparing to parallel system; 3. First-past-the-post provides additional seats (comparing to parallel system) to minority parties and non-partisan candidates. Detailed analysis results confirm, that party list system provides new parties with additional seasts in the parliament. At the same time, two biggest traditional parties would lose up to 28,89% seats comparing to the results of parallel system. Hypothesis that plurality / majority systems provides new parties with less seats comparing to parallel system was not only confirmed, but also showed, that such systems would prevent some parties from having at least one representative in parliament, although parallel system would grant 11,35% seats (16 out of 141). Plurality / majority systems would allow two biggest traditional parties to receive up to 30% additional seats in the parliament.
