I'm not aware of a specific study, but a large part of our work is looking at those factors. It's not as if we do just one study. We look at the impacts of all of those factors to try to understand what the impacts of those are on overall competitiveness.
You mentioned a couple of things there in terms of carbon pricing, and the carbon pricing system is designed in a way that essentially addresses some competitiveness issues for those sectors that are large emitters and trade-exposed. In the small business sector, we have, in comparative terms, a very low small business rate, in fact the lowest in the G7.
Those are just two factors in a range of factors, I think a couple of which you mentioned, so I think we continue to look at the implications of all of those for competitiveness.
