Constituency campaigning in parliamentary systems with preferential voting: Is there a paradox?

This paper sets out to show whether constituency campaign effects exist, particularly in the context of a preferential electoral system such as Australia's. Data from the 1993 Australian Election Study suggest that, despite the best efforts of the candidates, local campaigning has a very limited impact on the vote. The paper considers a range of possible explanations for this limited impact: displacement, MPs' perceptions of their role, sources of campaign information, the importance of party labels in Australia, party discipline. It concludes with an explanation for the apparent paradox of why candidates bother campaigning when it does not make a difference to their vote.
