Senator BIRMINGHAM (South Australia) (14:31): My question is to the Minister representing the Treasurer and the Minister for Climate Change and Energy Efficiency, Senator Wong. I refer the minister to the new partially leaked Treasury modelling of the government's carbon tax and ask the minister two very specific questions. Firstly, has this modelling been completed? Secondly, does this modelling still assume that real wages will adjust to offset the impact of the carbon tax so as to maintain full employment?
