JMM gives a good reality check here but I think Reece Martin is correct subways would be better BUT only if they were elevated. Elevated rail gets you the speed of grade-separated travel but significantly less cost than tunnelling.

Very apt for the habitual debate of TTC streetcar stops. It's astounding how slow they move because of how short the distance is between stops.

Olivier Blanchard (Olivier Blanchard) had a provocative post yesterday about a higher preference of French people for leisure: x.com/ojblanchard1/s… I have learned nearly an infinite amount of economics from Olivier since I was an undergrad, and he came to Spain to present a

Today, Luke Farrell explains how complex eligibility requirements have turned America’s safety net into a lucrative revenue stream for monopolistic private contractors.

If you haven't been following, there's been a great discussion about French labour productivity across several accounts here. Very stimulating debate about how to measure labour/leisure preferences!

You really have to enjoy the fact that during the period in which the debasement suddenly became a point of regular discussion among investors, this is what the price of bitcoin did

To most economists this is just obvious common sense. Good to see more evidence confirming it. The answer is just build more housing. Squeezing total supply in name of more “affordable housing” is just counterproductive.

Important new paper looking at well-identified historical US tariff shocks and their economic impact: real GDP, real compensation, real exports, and manufacturing production all down. by Diego Känzig & Tamar Besten

The critical issue facing Ontario now is the cost to build infrastructure (transit, utilities, hospitals, etc.) being so insanely high we are no longer capable of building it at all. The singular focus of politicians should be how to reform the system to build cheaply and fast.

New paper from Alberto Cavallo on Canada retaliatory tariffs. They appear to have increased the prices of Canadian retail products by about 6 percent when they were in effect, and prices fell rapidly when they were withdrawn. pricinglab.org/files/Canada_T…

Incredibly unjust policymaking in planning which is also happening in Burlington which adopted a new Official Plan but limits small and mid-rise apartments to major streets. #BurlON

Burlington is trying something bold to spark a housing rebound: a 2-year pause on residential development charges. Excellent column by John Michael McGrath doing a deep dive as to why the party is over when it comes to development charges revenues #onpoli tvo.org/article/analys…

Somebody please pass a law that makes citing "neighbourhood character" in any development decision illegal.
