I think you're going to be a bit disappointed with this answer. We don't model the employment insurance system directly.
In our macro models, we do model the extent to which there are automatic stabilizers in the economy. Largely, we do that based on when the economy slowed historically. How much did government revenue go down? How much did government expenditure go up? What is the automatic stabilizing effect that it has?
We sort of take the average stabilizing effect that we can observe over history and use that in our models going forward. We don't go a level deeper and model the various parts of those automatic stabilizers. Obviously employment insurance is one part, but we really look at the overall impact.
To get back to your previous question, I think automatic stabilizers play an important role in the economy. You want those to be effective. Then there are a lot of difficult discussions about how big you want them to be and all those sorts of questions, and I'm going to leave those questions to you.
