Why are the impacts of different types of spending different? Again, this is probably better directed at the Department of Finance. We do the best job we can in trying to look at the broad elements of federal and provincial budgets, and to build in the effects of different types of spending.
I'll give you examples.
If you're making an investment in a large infrastructure project that's going to be built over many years, the consequences of that spending are going to be spread out over a long time. You have to look at the profile of when it is. You also have to look at what it is, exactly. If the government builds a new building, it's all getting spent. The direct spending impact is bigger.
If you cut taxes, it will leave more money in the pockets of households, but they're not going to spend it all. They're going to save some of it. Some of it gets spent, some of it will add to demand and some of it will go into savings.
You mentioned, to use an example that was raised, the government's subsidizing of day care. That's having both demand and supply effects. It's making it easier for women with young children—for men with young children, too, but it's largely affecting women—to enter the workforce. That's increasing the supply of workers. Of course, new workers have new incomes. They're going to spend that money, so that's also adding to demand. These are examples of how different policies can have different effects.
When you get to housing, let's say a government gives people money to make it easier to buy a house. Of course, that's going to stimulate the demand for housing. It's not going to create more houses. In the current context, where the problem is supply, that would probably make the situation worse. However, the measures that improve the supply of housing will bring demand and supply into better balance.
Some of these measures are budgetary, but some of them are not budgetary. It's how approvals are done. It's how provinces, municipalities and the federal government are working together. It's not all budgetary items.
