    I think the title is a correct statement, and probably there’s some bad cycle of homeowners want to protect their investment → laws restricting development → it’s hard to live.

    BUT the economic reasoning that would back up that conclusion is like, absent? LIke the author seems to assume that the “natural” course of events is for home prices to increase at the same rate as inflation. But why would they?

    Some of my family members bought apartments in Manhattan in the 80s and 90s. Now those apartments are worth a shit ton of money. IS that related the harsh restrictions on development in manhattan, probably. But it’s also related to how Manhattan in the 90s was shitty and now it’s nice. That’s when Nas said “The city never sleeps, filled with villains and creeps. That’s where I learned my hustle, had to scuffle with freaks.” I hear a lot of stories about being mugged in central park and such from family members of that generation. So part of the reason those apartments are worth more is because they’re more valuable in a real sense, because the location they’re in is better.

    How this article describes that:

    And that reveals the true nature of housing prices. It’s not about the house, it’s about the location. Housing prices rise where more people want to move, but not enough houses are built to accommodate them. Aggregate housing prices do not rise because everyone’s retiling their bathrooms. They rise because the new demand outstrips the supply.

    The current regime of “housing as an investment” rests on the idea that rising housing prices are good, because they generate wealth. And sure, a homeowner whose house value is rising fast enough is getting wealthier.

    But it’s a fake version of wealth generation. The majority of the higher value comes from demand outstripping supply. Little actual value is being created, only transferred. Those who own houses gain wealth at the expense of the people who don’t, either through higher prices when buying or renting.

    Real wealth generation should create value. It should create more goods, more services, more capabilities to do things we couldn’t before. But there’s minimal new value reflected in the rising house prices. Sure, there’s your sweat equity. But most of the house value is just “more people want in, and there’s nowhere to put them.”

    OK, but why do more people want in? There’s no increase in real value, but more people want it… for no reason? My brother lives in a rowhouse in Philadelphia, those are still quite affordable. What’s the difference? The difference is the real increase in value of living in NYC, that it’s actually nicer and there’s better jobs there. That’s why the population of philadelpha is the same as it was in 1990–“more people want in” isn’t just some natural background process that has nothing to do with value.

    Yes, development in manhattan hasn’t been allowed to keep up with the increased demand for housing, but how big of a deal is that? Everyone gets so outraged, nobody seems to have an estimate of how much of a difference that made compared to other factors. The background assumption in this article seems to be not enough houses were built to accommodate the influx of people, and that’s why housing works as an investment that rises in value faster than inflation. But what are the assumptions that imply it “should” have risen at the same rate as inflation, that if we hadn’t been treating housing as an investment then the precise amount of development would have occurred so that the apartment prices keep pace with inflation?

    Because if housing supply isn’t artificially constrained you should expect rising housing costs to lead to more building, which should lead to lower housing costs. Yes, there’s an upper limit to this, in that you can only build so high and land is finite, but we’re nowhere near that limit.

    It should increase at the level of inflation for the same thing everything else does: Most other products do not have artificial scarcity legally mandated, so the rise in price reflects actual relative changes in the costs of making goods.

    I would expect in a world without artificial constraints the price of housing in Manhattan would still have gone up, but nowhere near the levels it does in our world.

    It should increase at the level of inflation for the same thing everything else does

    Except, as I already said, it’s not the same product. A 2023 Manhattan apartment is actually better to live in than a 1995 Manhattan apartment, even if it’s the same apartment. That’s not true of a 2023 Manhattan loaf of bread. Where the city has stagnated, home prices often are low, but we tend to avoid those places.

    Also, there’s the fact that home prices depend on financing. That is, the money you actually pay is the nominal cost plus the interest paid. If I recall correctly, the rise in average home value, rather than in cities we want to live, seems to track pretty well the decrease in mortgage interest rates, so people are effectively paying a similar amount.

    You’re making a quantitative judgment without any quantitative knowledge to base it on. You don’t know the relative contribution of artificial scarcity and other factors, and neither do I.

    As for the financing, if people are going deeper and deeper into debt to buy houses, that still seems to point to a situation where the supply is limited, and that’s why they need to outbid each other. So I think such loans could be another government policy which aims at propping up house values, in addition to building restrictions, but the two go hand in hand.

    I think the framing “how much of a difference [restrictions on building supply] made compared to other factors” is perhaps not the right one, because you can imagine several different interventions to lower the cost of living in NYC. You could start a gang war outside so nobody wants to live there, or you can build many more apartments so that each one becomes dirt cheap. Either one could drastically lower prices, so you could say that the current cost is nearly 100% due to lack of gang wars and nearly 100% due to lack of supply.

    Maybe that’s just a quibble, either way it would be good to have some quantitative data about what the prices would be like under various policies, do make more informed decisions.

    I think one interesting philosophical point is that, while it’s certainly tautologically true that the tiny NYC apartments are worth whatever they cost (or people wouldn’t pay for them), that value is then largely captured by whoever owns the land the apartments are on, even though the land-owners did not produce it. The value is more due to the people who live in the apartments, because they are the ones who make the city nice to be in. One common justification for capitalism is that it’s meant to optimize the economy by directing capital towards the most high-return investments, but if the returns are captured by a third party you don’t get that. This is, y'know, a problem of rent seeking.

    ok there’s a lot i don’t agree with here but i think it belongs in another thread. But

    Maybe that’s just a quibble, either way it would be good to have some quantitative data about what the prices would be like under various policies, do make more informed decisions.

    This is sort of what I’m getting at. Figuring out the consequences of econ-type policy is really hard. So what I really want to say here is like, the conditional distributions P(rent | do(artificial scarcity)) is unknown, like not just the outcome is unknown but we don’t have good econ models to get that distribution from… I mean, maybe an economist does, but you don’t, I don’t, person who wrote the author of the post doesn’t, the people who spread libertarian memes don’t. And probably an economist doesn’t either but they lay out their assumptions at least.

    i’m always looking at my phone and exposing myself to memes that circulate among Bay Area libertarians, and it’s like, they’re mostly right I think, FDA restrictions are too tight, nuclear regulations are too tight, restictions on development are too tight. But I’m making those judgmetns on principle. I think if you increase freedom across the board stuff’s gonna get better but I can’t say how things will turn out in any individual case because I don’t know if the regulations are the dominant effect, the rate-limiting step. That’s a quantitative judgment that I can’t make and you can’t make. But the memers never seem to doubt that we could have had vaccines that kept up with the variants, that we could have had an era of nuclear energy abundance, and it could have been cheap to live in manhattan, if only we did the libertarian thing. I think if we did the libertarian thing we’d make things better in some cases and in other cases find out what else is holding us back.

    While I totally agree that the “what” of that situation cannot be measured – or not without some very complicated and controversial economic modeling – I don’t see the problem with it being understood as a causal question (or at least, a causal determining part). We understand “X causes Y” when there is some relationship between them (correlation) that can be analyzed causally (at least in the intuitive sense of “causes”); we don’t understand X to “cause Y” when the relationship is purely correlational, no matter how strong. The causal graph between two variables is not always a tree; it may contain loops and multiple arrows between some pair of variables at once. That can be important. For instance, when a person who smokes and is depressed also has an eating disorder, it is not a causal graph with no loops or multiple arrows: the smoking causes both the depression and the eating disorder. Of course I am open to arguments that this isn’t very important in a lot of cases; I’m not an “X causes Y” believer by default, and you may be able to convince me with your very simple causal models that a smoking person is never affected by an eating disorder, in which case the causal graph with no loops is enough for me. This kind of argument may be important in some specific instances – I’m not sure where smoking falls under the heading “breathing problems,” but I am certain that eating disorders can’t be determined solely by correlating an eating disorder and a smoking patient and an eating disorder patient. I may well be wrong here. And in other instances too. This kind of argument could certainly be true in a lot of very common cases, where I am not even open to arguments that we can dismiss it as “not very important,” let alone that the “causal relationship” in the sense of “causes” is required by the “determining” sense of “determining.”

    The “what” part of that question is determining or determining, not undeterminable as in “mystery”; the question of the effects of regulation or supply in NYC on apartment prices is determining because we cannot say for certain that it caused the price changes or just tracked inflation; the question of the effect of supply or artificial scarcity in NYC on home prices is determining because the causal graph between two variables does not in fact have no loops or multiple arrows and this is important in a sense that is not amenable to statistical methods like linear regression. I don’t agree that the “what” part of the “what will be the effect of X and Y under Z policy” questions is unknowable (for certain values of “unknowable”). I also can’t be sure that a libertarian policy in NYC would decrease the cost of living. And it’s important to remember that, whatever the “consequences” are, the question of whether we should be doing the X and Y under Z policy can only be answered by looking at the effectiveness of that policy under Z policy, and the effectiveness of Z policy (which of course depends on that policy question and our implementation) depends on the consequences, etc. In a non-contradictory way. And that’s a qualitative judgment that we can’t make based on our ignorance about econ models and the like.

    You can, however, look at the effect of X and Y under Z policy. And in NYC, at least in my opinion, X=Y does not cause any negative consequences. In other words, in NYC under the current rules Z, X is beneficial to Y, and then (if) any given negative consequence C, the benefits of X and C outweigh the costs of C and X. Here are some ways we can say that this is true, although I don’t know the quantitative or “causal” impact:

    • there is a positive correlation between the rates of consumption of X and C
    • there is a positive correlation between the number of hours of C consumed by C and the costs of C and X, given C and X
    • some portion of the benefits of X and C can be paid for in the cost of C.
    • all of the benefits in cost of X and C are costs that are compensated by C, and the benefit that’s not paid for by C. And some of the cost of C is because of that.

    or I don’t know what sort of reasoning has to be involved with those kinds of claims, but maybe they aren’t actually as straightforward as we think them to be. The point being, of course, we don’t know what would be the effects of X and Y under Z policy in NYC. The author of the post knows this. We know this because of the post, and we don’t really know what else there is to know. You can, of course, judge on that basis of things that are known, like how much would X and Y change the price of NYC apartments under various policies. But this is not about “the effect of X and Y under Z policy” – the costs of doing that are known, etc.

    The “whether to do X and Y under Z policy” can be answered by looking at how it changes the “effect of X and Y under Z policy,” and in NYC there is no “negative effect,” so that is an acceptable policy.

    (I think it will be an easier policy for NYC to make than for SF, just because of population size, because a smaller population changes things in ways that make the population as a whole more homogeneous. If there were more people in SF they would be able to get “negative effect” policies through just voting to make SF nicer. NYC is already pretty nice, so this won’t be a matter of adding “negative effect” – so SF people will get the policy. (And SF’s status will be improved, in the same way that people get benefits from better buildings – I don’t know how well this works in practice).)

    (I also think that the “negative” effects of X and Y under Z policy that you would find if you were looking at that could be zero in practice. So that’s an argument, even though we don’t have “the quantitative impact” that it’s important for us to know. I hope “the quantitative impact” of X and Y on the price of NYC apartments, under various Z-policy scenarios, is easy to figure out. I don’t know, or suspect, that I could figure it out on principle from libertarianism alone (even if I have some econ model laid out).

    I’m making these judgements mostly on principle (that is, whether they can be justified for sure, not just in principle), and in practice the answer seems to be in the negative. I don’t know, and I hope I can’t predict. We don’t even know if there are any “negative” impacts, because, as you say, there is no “negative” impact.

    There is a sort of theoretical connection between the “quantitative impact” of X and Y and the “quantitative impact” of X and Y under Z policy, and I know this because I read the “Causal Determining” section of a libertarian’s meme about a “quantitative impact” section of the “costs of X” part of the “negative effect” part of the “effect.”

    You are also looking for “effects” or “consequences,” not “quantitative impact.” There are many possible ways for X and Y to change the probability of an adverse reaction of C under various Z policy scenarios; if you were to look to any such data set you would find that these quantities will be correlated
