We're using slightly different models, with slightly different assumptions, leading to slightly different results.
When it comes to the assumptions, we try to be as balanced as we can when we do our own simulation. We don't have an agenda when we do our simulation. We're essentially trying to reflect to the best of our capacity the potential impacts of trade policy changes on the domestic economy.
As you can imagine, essentially simulating a reduction or an elimination of a tariff rate is pretty straightforward, but it's very difficult to make assumptions when it comes to looking at trade costs for services or for investments and what the impact will be of liberalizing investment regimes on foreign investment flows, for example. These are difficult assumptions to make.
We've been looking at these things for a long time. We do simulations. We do assess most trade policy initiatives taken within the department, so we're quite comfortable with that. We have a range, and we work with worldwide experts on assessing the impact of changes to trade policy on trade costs and trade flows. We're quite comfortable with the assumptions we've made.
There are some aspects that we don't model because they would lead to essentially very marginal impacts, non-significant impacts. We try to capture, through our assumptions, the key drivers of the changes in the domestic economy.
