Thank you for the questions.
The first part is just the pure metrics of it. Business investment is part of the larger composition of the national accounts, and the national accounts are a metric that is used globally. This is an OECD and United Nations standard in terms of how we effectively quantify economic activity and specifically economic growth: the composition of the economy across the world.
Business investment fits within domestic demand within an economy: business investment, residential investment, investment into inventories, and also consumption. That's the basket of domestic private sector activity that forms part of the national accounts. Clearly, business investment is a tranche within that, and that's investment in machinery and equipment and capital structures. I hope that's clear. That's part one, just in terms of the metrics.
Part two, what has the government done to effectively lead to a statistic around more robust business investment? I'd say a couple of things. One is tax incentives. We have the lowest marginal effective tax rate on new business investment in the G-7, so amongst large advanced economies we have the lowest tax rate on new business investment. Obviously it goes without saying that this incentivizes new business investment. Likewise, other types of tax incentives, such as the accelerated capital cost allowance over the last couple of years, have further boosted the incentive to invest in machinery and equipment and in capital structures.
