Abstract

The paper concerns the choice of an electoral system for a 100-member parliament. Nine electoral system have been simulated through a specific program. They have been evaluated with reference to representativeness and to governability, as resulting from given indexes. A system is considered dominant if ti scores higher than any other with reference to both indexes. No dominant system results. There are some indications that the improvement from the use of complicate voting (e.g. Borda counting) is not large. The Condorcet performance of the systems is influenced by the structure of the preferences; this casts some doubts on previous experimental results.
