Australian Democracy: Modifying Majoritarianism?

The use of the single transferable vote (STV) for Australian Senate elections since 1949 has modified the majoritarianism of Australian democracy in two ways. First, it has increased the differences between the two houses of the legislature and hence strengthened the bicameral system. Second, it has operated like a true PR (proportional representation) system, and it has therefore increased the overall proportionality of political representation at the national level. In modern democracies, PR does not have negative effects on the quality of macroeconomic policy-making-contrary to the conventional wisdom on this matter. And PR has a strong positive effect on important democratic qualities like women's representation, income equality, voter turnout, satisfaction with democracy, and the proximity of the government to the median voter.
