Gherardo Caracciolo here: I suggest the author of this post reviews what a difference in difference is, and how it is carried out. Clearly it hasn't been understoond.

CD Howe was cited the other day to prove that gas prices in Vancouver are entirely due to pipeline capacity, that it's just a myth that there is collusion in the industry.

....but they don't explain why the gas prices drop as soon as you leave Vancouver itself. The study just doesn't look at relative pricing as you go up the #1 or the #5, further away from the big market, but not from the pipeline issue.

So I'm kind of suspicious of CD Howe for some time to come.
