So the author is discovering Say's Law [1] - basically supply can create it's own demand. Now if you talk to an economist they'll tell you Say's Law is bunk and has been for quite a while, supply doesn't create it's own demand. But let's say you don't mention Say's Law and you talk to an immigration economist, they'll say something like immigration is good because the supply of new labor actually creates even higher demand for labor than what they displace, basically Say's Law but disguised. Which is all to say, does supply drive it's own demand? Hard to say but regardless YIMBYs need to deepen their explanations of the economics behind the issue, supply and demand graphs are good for introducing undergrads to the basics, they're not good for justifying very expensive and highly redistributive policy. [1] https://en.wikipedia.org/wiki/Say%27s_law https://en.wikipedia.org/wiki/Say%27s_law sidenote: draw a supply and demand graph. Now draw a second graph but make demand slightly upward sloping. Increase supply. What happens to price? Just googling around I found several articles about upward sloping demand in housing. It appears to be contentious (urban economics isn't an area I know too much about) but is something that should be considered. http://worthwhile.typepad.com/worthwhile_canadian_initi/2017/08/upward-sloping-demand-curves-for-labour-and-housing.html http://worthwhile.typepad.com/worthwhile_canadian_initi/2017... https://www.ssb.no/a/publikasjoner/pdf/DP/dp618.pdf https://www.ssb.no/a/publikasjoner/pdf/DP/dp618.pdf https://ideas.repec.org/p/arz/wpaper/eres2018_267.html https://ideas.repec.org/p/arz/wpaper/eres2018_267.html https://www.sciencedirect.com/science/article/pii/S0094119006000799 https://www.sciencedirect.com/science/article/pii/S009411900...
