  3. All that glitters: the betting markets and the 2013 Australian Federal election
    Poll movements shape the betting markets, especially as the election draws close, and especially when the polls suggest the election might be closer than previously thought. Ahead of the 2013 Australian Federal election, Newspoll and Nielsen seem especially important "market movers", probably due to their long-standing brand power and their association with newspapers in multiple media markets. Betting markets react quickly to changes in the polls, but not instantaneously. Poll movements take at least 48 hours to be digested by the betting markets, suggesting that secondary media reports of the polls are important (e.g., evening TV news reports of poll results from that morning’s newspapers). In a lop-sided election like 2013, we can expect that betting markets will react to little or no change in the polls,"catching up" with the polls in the final week of the campaign. That is, we should not to be surprised to see political betting markets reacting to polls. Rather, we should expect a somewhat subtle interplay between the two, as shown in the analyses presented here.

  6. A shrinking Australian electoral roll?
    with Peter Brent
    We examine recent trends in electoral enrollment in Australia, which suggest that since the 2004 Federal election, enrollments have fallen as a share of the eligible population. Recent months have seen a marked increase in enrolment, but the disparity remains. We suggest some reasons as to why this has occured. Democratic Audit of Australia
  7. Pooling the Polls Over an Election Campaign
    Poll results vary over the course of a campaign election and across polling organisations, making it difficult to track genuine changes in voter support. I present a statistical model that tracks changes in voter support over time by pooling the polls, and corrects for variation across polling organisations due to biases known as ‘house effects’. The result is a less biased and more precise estimate of vote intentions than is possible from any one poll alone. I use five series of polls fielded over the 2004 Australian federal election campaign (ACNielsen, the ANU/ninemsn online poll, Galaxy, Newspoll, and Roy Morgan) to generate daily estimates of the Coalition’s share of two-party preferred (2PP) and first preference vote intentions. Over the course of the campaign there is about a 4 percentage point swing to the Coalition in first preference vote share (and a smaller swing in 2PP terms), that begins prior to the formal announcement of the election, but is complete shortly after the leader debates. The ANU/ninemsn online poll and Morgan are found to have large and statistically significant biases, while, generally, the three phone polls have small and/or statistically insignificant biases, with ACNielsen and (in particular) Galaxy performing quite well in 2004.

Andrews Bill, 1996
There are few “conscience” votes in the Australian parliament (members of parliament almost always vote as party blocs). A few years ago I collected data on passage of the Euthanasia Laws Bill 1996 (the “Andrews Bill”), a private member's bill to overrule a Northern Territory statute permitting euthanasia. The vote on the 3rd reading (final passage) of the bill in the House of Representatives (9 December 1996) is here as a raw text file.
