There are maybe two things.
The forecasting ability has improved over the years. The economy does change, and I'll leave it to my colleagues from Finance to explain what has happened on the economic side. If the theory is that there's deliberate pessimism in the forecast—there is a bit of that—for risk, Finance will speak to that, but is there any systematic deliberate under-forecasting? No, there's not. It is challenging, based on all the economic results and what's happening globally today.
The only thing I will say on the PBO is that they're takers. Yes, they have some things they have to do, and the members of Parliament make individual requests. I think a fair question to them is on how you make sure they allocate their resources to the right priorities. Is it useful for them to challenge the government's forecasts given that you have all of these private sector forecasts out there as well, or is that just duplicative? I think that's a good question.
I'll leave it at that.
