Peter Van Onselen, definitely one of the rising stars of Australian political science, has a piece in the Bulletin this week on betting markets, which includes this tidbit.
The Bulletin understands that political insiders, armed with internal party research, are dabbling in the betting markets, particularly in seat-by-seat contests. Due to privacy laws, betting agencies cannot disclose the names of individuals who place bets. It is believed, however, that they include sitting MPs, betting both on and against themselves. Profiteering by political insiders has a stockmarket insider trading feel about it, except that it is not illegal.
Over lunch with an election bookmaker recently, I was told about three other groups that frequently bet in these markets: political staffers, union officials (betting on both parties, apparently), and opinion pollsters themselves.
