Real estate is fundamentally depreciating: you build a building, it exhibits wear and tear, it's worth nothing in the long run. Assets are usually valued off of future cashflows, which would be the long-run rent it can fetch. For most investments, you just shove this into a calculator with the current risk free rate and it spits out a number that's the current price. The rent declines in the case of a building with the wear until it's condemned, at which point it goes to zero. I'm saying this because just because something is fundamentally depreciating doesn't mean it won't have real yields, my point is looking at the yields from a capital appreciation perspective is kinda distracting where fundamental yields come from. Usually, capital appreciation is far more muddled (did capital become cheaper, leading to bidding up of yields? did people secularly just want to pay more for renting a house? etc)

Of course in the US there's been huge capital appreciation: housing and shelter went from 10% of CPI in the 60s to 40% of CPI today! Are you going to keep drawing the line and say "yeah, it's totally reasonable for us to continue it to have capital appreciation out-of-line of actual yields when supply and demand are balanced" - like how far is enough for you? 50% of CPI? 60? You're never going to be able to get the real appreciation that we've had over the last 40 years because that'd take us to 160% of CPI!!!

You understand that a real estate asset is not just the building, right? The land is what typically appreciates in value (maybe the building depending on labor/material costs). I've also already pointed out that recent history is anomalous in terms of property appreciation. Still historical averages are generally positive.

Regardless, all of that is a digression from the original question: does Japan have a similar dynamic where the bulk of household net worth is tied up in real estate? That's central to my claim that people are more protective of the assets tied to their wealth. In other words, we need to be careful about thinking Japan provides an example if there is a different wealth dynamic. It seems like you are trying to have a different conversation.

I don't talk about your point because it's kinda irrelevant? Like it doesn't extend from "wealth is tied up in x" to "we should cartelize around x to push it above fundamental value."

All it takes to understand the relevance is the understanding that outcomes are coupled to incentives. You think it’s irrelevant to NIMBYism that people have incentives to protect their wealth? I…dont think many (any?) economists would agree with you.

To be generous so as not to think you just have a problem conceding a point, you seem hung up on the moral argument. I’m not making a moral argument. I’m explaining the how it is, and not making a claim about how it ought to be. FWIW I think it’s stupid that people have 70% of their wealth tied up in a non-liquid asset, but that’s the scenario we’re dealing with. People are incentivized to keep their wealth high, and especially home wealth because it gives them equity to borrow against. Likewise governments like having high property values because it gives them a larger tax base.

So there’s two salient aspects to the point: 1) people have a say in how they are governed in a democracy and 2) people/govts have economic incentives to protect their wealth/tax base. NIMBYism is the convergence of both. So which do you disagree with?

[JackYoustra]

Oh, I see. This makes more sense.

I agree that, insofar as local governments go, NIMBYism is the inevitable convergence of both, and if the story stops there, there's not too many scalable solutions. I guess my point is that NIMBYism need not be the convergence of both in the general case. In CA at least, forming a YIMBY coalition is (obviously) democratic and is formed in response to housing being 40% of CPI (so trying to increase aggregate wealth). The reforms need not cause nominal declines in housing prices! Merely stopping growth is enough to cause real declines.
