Political parties, electoral systems and democracy: A cross-national analysis

The number of political parties and the type of electoral system may impact the level of democratic functioning within a government. Models are used to explore whether the number of political parties increases a country's democracy score on the POLITY IV measure of democracy, and whether countries with proportional representation electoral systems have higher democracy scores than those without. Multiple regression analysis reveals that countries with proportional electoral systems have higher democracy scores. Countries involved in the Third Wave of democracy may find the choice of an electoral system among the most important issues in structuring a democratic government.
