Mr President, I ask a supplementary question. I again ask the minister if she can confirm whether the modelling to which the Treasurer has referred has been finished yet. Further, can the minister explain why the government claims that the carbon tax has no impact on employment when—unless they have reversed their previous approach—the government's modelling starts with the assumption of there being no impact on employment? Will the minister inform the Senate how much lower real wages will be in 2020 under the carbon tax?
