Mathieu Laberge, Chief Economist at the Canada Mortgage and Housing Corporation, has a good article out today on why you can’t subsidize your way out of Canada’s housing affordability crisis: simply helping potential homeowners with their mortgage payments ends up raising house prices for everyone. This in turn raises the price-to-income ratio for housing and deepens the housing affordability crisis overall. To avoid this outcome, you need policies to promote homebuilding and increase the housing supply beyond projected levels.

A good following on housing policy in Canada, particularly on supply-side interventions, is economist Mike Moffatt of the Missing Middle Initiative.

Four-panel meme about housing policy. In the first two panels, a simple cartoon figure thinks, “i just need to subsidise demand.” In the third panel, a circular flow chart shows “subsidise demand” leading to “home prices go up,” then “people get angry,” then back to “subsidise demand.” In the final panel, someone asks, “Are u okay bro?” while the figure is surrounded by chaotic black scribbles and replies, “yes i just need to subsidise demand.”
