Month: November 2022

Is the EA movement dead?

No.

To be clear, I am not “an EA person,” though I do have sympathies with considerable parts of the movement.  Most of all it has struck me, as I have remarked in the past, just how much young talent the movement has attracted.  Money enabled the attracting of that talent, but I never had the sense that the money was the reason why the talent was showing up at EA events.  So a less well-funded EA movement still will be potent, at least assuming it gets over the immediate trauma.  That trauma may even help to drive away some of the less serious poseurs who thought EA was the easiest path to polyamory, or whatever..

Intellectual movements can be quite influential on small sums of money.  What exactly was the budget for the Apostles?  Or take libertarianism, which arguably saw peak influence in the last 1970s and early 1980s, when it was much less well funded than in later times.

How much money did the Benthamites have?  Nonetheless they influenced policy a great deal.

As a side note, Open Philanthropy spent over $400 million in 2021.  I know zero about their plans, but I don’t see any reason to think they will be unimportant in the future.  That is plenty of funding right there.

A mere month ago, I witnessed the game of young people sitting around, speculating how many future billionaires will be attracted to EA.  Probably that number has fallen, for reasons related to the current bad publicity, but I don’t see why it has to have fallen to zero.  The next set of billionaires might simply choose a different set of labels.

I do anticipate a boring short-run trend, where most of the EA people scurry to signal their personal association with virtue ethics.  Fine, I understand the reasons for doing that, but at the same time grandma, in her attachment to common sense morality, is not telling you to fly to Africa to save the starving children (though you should finish everything on your plate).  Nor would she sign off on Singer (1972).  While I disagree with the sharper forms of EA, I also find them more useful and interesting than the namby-pamby versions.

Tyrone knocks at the door: “Tyler, you are failing to state the truth about SBF!  He did maximize social welfare!  And sacrificed himself to that end.  What indeed is Christ without Judas?  Judas sacrificed his reputation.  So did SBF.  Now the jump-started EA ideas will live on for eternity.  And those who hold crypto through Caribbean exchanges are about the most deserving losers you can think of.  Those assets did not represent social value anyway.  And isn’t discouraging crypto investment exactly what we should be doing?  (SBF is good for the environment!)  And you need a celebrity example of wrongdoing for that lesson to stick, not just a few random price drops for bitcoin.  He is surely a true angel…”  At which point I had to ask Tyrone to leave the penthouse and shut his dirty mouth…he is not a valid boy!

Why is the New World so dangerous?

I’ve been asking people that question for years, here is the best answer I have found so far:

We argue that cross-national variability in homicide rates is strongly influenced by state history. Populations living within a state are habituated, over time, to settling conflicts through regularized, institutional channels rather than personal violence. Because these are gradual and long-term processes, present-day countries composed of citizens whose ancestors experienced a degree of “state-ness” in previous centuries should experience fewer homicides today. To test this proposition, we adopt an ancestry-adjusted measure of state history that extends back to 0 CE. Cross-country analyses show a sizeable and robust relationship between this index and lower homicide rates. The result holds when using various measures of state history and homicide rates, sets of controls, samples, and estimators. We also find indicative evidence that state history relates to present levels of other forms of personal violence. Tests of plausible mechanisms suggest state history is linked to homicide rates via the law-abidingness of citizens. We find less support for alternative channels such as economic development or current state capacity.

That is from a new paper by John Gerring and Carl Henrik Knutsen.  It is also consistent with so much of East Asia having very low murder rates.  Via the excellent Kevin Lewis.

How will crypto clearinghouses evolve?

That is the topic of my latest Bloomberg column, here is one excerpt:

The upshot is that there is a tendency for members of a clearinghouse to either a) fail to meet standards and go bust, or b) join or least collude with a dominant coalition.

And:

You could also argue that a dominant clearinghouse might be good for crypto. The history of banking includes dominant or semi-dominant clearinghouses stabilizing markets and helping to introduce innovations, for instance of timeliness and transparency. The collusive monopoly might take too big a share of the market surplus for itself, but it has an incentive to keep the market up and running and profitable. That is hardly the worst arrangement crypto might stumble upon.

It is also true that a dominant clearinghouse is much easier to regulate, and indeed modern central banks often sprung out of these earlier clearinghouse arrangements. Sooner or later, there is a tendency for the law to intervene and turn the dominant private clearinghouse into part of a more formalized central bank. It is no accident that member banks of the Fed are still called “stockholders.”

One complication is that Binance is not a US firm; incorporated in China, it is now based in Dubai. Regulators might hope an American or at least Western version of Binance comes along, perhaps to create a new market duopoly. Arguably that is what regulators were hoping all along for FTX, so at least one version of the previous plan now has a huge hole in it. All the more pressure will be placed on Coinbase (a US firm), which may gain business but face a heavier regulatory burden and be expected to play a more specific role in the system.

When guessing at the future of crypto, keep in mind that the future of crypto exchanges and the future of crypto assets are very different things. For many pure crypto bugs, the exchanges are a sellout and a concession to older methods of finance and settlement. The exchanges can be regulated, controlled and co-opted, even turned against the notion of individual monetary sovereignty. Instead, the pure crypto vision stresses the notion of “every person their own bank,” through the medium of a personal wallet and beyond easy purview of the central authorities.

We should all be rereading Charles Goodhart…

Redux, my CWT with SBF

I won’t indent:

COWEN: I have some crypto questions for you. Is there, in fact, any way to coherently regulate stablecoins? I see what the proposals say: It’s all about capital requirements, deposit insurance, treat it as a bank account, like a new kind of money market fund. Can that possibly work? Doesn’t it end up having to be applied to all of crypto, all payments companies, PayPal, whatever else? What’s really there that they can do?

BANKMAN-FRIED: That’s a really interesting question. First of all, I will say, I think there is something that does work compared to the current environment, but I’ll get to your point — it’s actually a good one. If you just said, “Look, all stablecoins have to be fully backed by the dollar and have to have audits to confirm that they are in a bank account,” that would get a pretty safe product that was well understood, well regulated, and frankly would be, from a product perspective, just as good as current stablecoins. That’s what all the stablecoins are doing today.

It’s a mess because there’s no clear regulatory framework for them to fit into and to have oversight of that. So, part of my answer there is, basically, yes, I think that framework would solve the current problems that people have in a pretty clean way. But you have a good point there, which is, how about PayPal? There are all these things that we don’t call stablecoins right now, that we call something else.

COWEN: PayPal promises me a dollar, and they give it to me. I’m happy, right?

BANKMAN-FRIED: Exactly. In fact, a lot of these look a lot like stablecoins when you drill into it. When you really dig into it, what is the difference between PayPal and USDC? I guess there’s some differences, but I think there are more similarities than there are differences, to be honest. What does that imply for PayPal? You can just say, whatever it implies, stablecoin is not PayPal — it’s how it is.

I think there would be a big improvement over the current world, where it’s the same thing but without regulatory oversight and with a lot of random drama because of this. But I do think that it gets to this question of, “Wait, but banks are allowed to rehypothecate dollars. Banks are allowed to do all manner of wacky things with their deposits.” Are stablecoin companies allowed to? If not, is it obvious they shouldn’t be allowed to? And how should that be governed and regulated?

Maybe the answer is, whatever: The banks will do that on their behalf, the banks where they hold their assets, and then pay them interest for the right to do that — although, of course, right now banks aren’t actually paying interest, really . . .

COWEN: Not to me. Also, how stable does a stablecoin have to be to be regulated as such? If there’s any regulatory definition, won’t a lot of people just camp their crypto assets to be just slightly more volatile than wherever the line is drawn, or you’d just end up regulating all of crypto? How does that work?

BANKMAN-FRIED: This could go in a few ways. Is your thought that people will attempt to get just barely into the regulatory system or just barely out of it?

COWEN: Maybe both, but a lot of people will go out of it. So I’ll issue something. I’ll call it a “not stablecoin,” but de facto, it will be very stable. But also, “Oh, it’s just sort of an accident. Oh, who knows what the markets going to do today?” It’s just stable for decades. How do you regulate that?

BANKMAN-FRIED: Oh, that’s a really good question. Of course, what it gets you is this question of, what if a stablecoin didn’t promise to be a stablecoin? Is it bad that it’s backed by the dollar? Does it somehow make it worse from a regulatory perspective? Why is it being held to a higher standard?

COWEN: Exactly.

BANKMAN-FRIED: I do think there’s a little bit of an answer here, although I also think that this is getting at another point, which is, you could reasonably say, “Look, are consumers doing what they’re doing with their eyes wide open?” If there’s sufficient disclosures and transparency, shouldn’t people be allowed to use stablecoins with some risk in them?

I think that’d be a reasonable thing to think, but if you put that aside for a second, you say, “No, absolutely not.” Here’s one difference between that and the stablecoin, which I think is relevant, is that a stablecoin is not just stable in one direction. It’s stable in both directions. In particular, if you’re an investor, and you buy a stablecoin, you have downside risk but not upside. If somehow the stablecoin company makes money, you’re probably not going to get any of that, but if it loses money, somehow, you’re probably on the hook for that.

So, there is something a little asymmetric going on here for the consumer. I think it wouldn’t be crazy from that perspective to think that there should be some protection here and that maybe there should be regulation if consumers are only given one side of exposure, but I don’t think that’s obviously true. I think you’re making a decent point.

COWEN: Now, if we look at DeFi, there are some forms of obvious, explicit leverage, like people borrow money to participate in the system. But those aside, I’ve learned over my life, if you look at any system, any institution, typically there are forms of hidden implicit leverage in those institutions. Might be good, might be bad, but it’s there, and in a sense, you don’t understand the institution until you understand where’s the implicit leverage in this game. In DeFi, where is the implicit leverage? Is it rehypothecation, or where is it? What is it?

BANKMAN-FRIED: Ignoring the explicit leverage of borrow-lending protocols —

COWEN: Yes, which is easy to see, right?

BANKMAN-FRIED: Which is easy to see, yes. So, what happened in 2008? What caused the collapse in a lot of things? That’s sort of a dumb question, but one of the things that led to this is that no one knew how much leverage there was, really, in the system. As you said, there’s always implicit leverage, and in this case, it was all of these bespoke OTC swaps between banks that basically didn’t get reported anywhere. In fact, those got rehypothecated again and again and again. No one was keeping track of the total notional fees. It was impossible to — they weren’t public.

One thing you could do is look for a similar thing in crypto. You could look for OTC transactions. You could look for OTC swaps that live on. You could look at OTC borrow-lending. Those are in crypto. Are they in DeFi? It’s sort of ambiguous — they touch all areas of the crypto ecosystem.

But that’s an area where I think there’s some dubiously accounted-for leverage. I think that’s one answer to that question. Where else is there leverage that sort of is implicit? Rehypothecation sometimes, although in DeFi, because it’s all on-chain, it has to be pretty explicit if it’s going to be rehypothecated, but you’re not . . .

COWEN: But it’s hard to see, right? If you traced everything, you could find it, but no one’s actually watching it. Or are they?

BANKMAN-FRIED: Well, they’re halfheartedly watching it maybe, is how I’d put it, which is not great. Maybe full-heartedly watching it. I could imagine arguing for people full-heartedly watching it, and that would be a reasonable thing for them to be arguing for. In particular, if someone releases a protocol, there’s a question of, well, is that protocol rehypothecating? You just look at the code and see if it can rehypothecate, right?

In general, people actually often do know whether each protocol individually can rehypothecate, which is a separate question from whether they, as a group, can or whether they are or something. But in fact, most of these aren’t. Most DeFi protocols are not doing things beyond what they literally say they’re doing, and so the amount of leverage they introduce into the system mostly is what they say they are.

But here are some hidden things. First of all, you take one leverage thing, you put in another leverage thing, so DAI. DAI is an algorithmic stablecoin. Like other algorithmic stablecoins, it is not perfectly stable. It’s not perfectly stable because it’s not backed by the US dollar. It’s backed by crypto assets that could have price movements. It’s very overcollateralized. DAI can then be used as collateral on some borrow-lending protocols in crypto. That’s one form of rehypothecation in DeFi markets that you can trace through. It is, in theory, public, but it’s not super easy, necessarily, to trace through.

COWEN: Now, for mathematical finance, as you know, we at least pretend we can rationally price equities and bonds. People started with CAPM. It’s much more complicated than that now. But based on similar kinds of ideas — ultimately arbitrage, right? — if you think of crypto assets, do we even have a pretense that we have a rational theory of how they’re priced?

BANKMAN-FRIED: With a few of them, not with most. In particular, let’s talk about Dogecoin for a second, which I think is the purest of a type of coin, of the meme coin. I think the whole thing with Dogecoin is that it does away with that pretense. There is no sense in which any reasonable person could look at Dogecoin and be like, “Yes, discounted cash flow.” I think that there’s something bizarre and wacky and dangerous, but also powerful about that, about getting rid of the pretense.

I think that’s one example of a place where there is no pretense anymore that there is any real sense of how do you price this thing other than supply and demand, like memes versus — I don’t know — anti-memes? I think that more generally, though, that’s happened to a lot of assets. It’s just less explicit in a lot of them.

What is Elon Musk’s greatest product ever, or what’s his most successful product ever? I don’t think it’s an electric car. I don’t think it’s a rocket ship. I think one product of his has outperformed all of his other products in demand, and that’s TSLA, the ticker. That is his masterpiece. How is that priced? I don’t know, it’s worth Tesla. It’s a product people want, Tesla stock.

COWEN: But the prevalence of memes, Dogecoin, your point about Musk — which I would all accept — does that then make you go back and revisit how everything else is priced? The stuff that was supposed to be more rational in the first place — is that actually now quite general, and you’ve seen it through crypto? Or not?

BANKMAN-FRIED: Absolutely. It absolutely forces you to go back and say, “Well, okay, that’s how cryptocurrencies are priced. Is it really just crypto that’s priced that way?” Or maybe, are there other asset classes that may claim to have some pricing, or purport to, or people may often assume it does, but which in practice is not exactly that? I think the answer to that is a pretty straightforward yes.

It’s a pretty straightforward answer that you look at Tesla, you look at a lot of stocks right now, you think about what determines their market cap — the discounted cash flow? Yeah, sort of, that plays a role in it. That’s 30 percent of the answer. It’s when we look at the meme stocks and the meme coins that we feel like we can see the answer for ourselves for the first time, but it was always there in the other stocks as well, and social media has been amplifying this all over the place.

COWEN: Is this a new account of how your background as a gamer with memes has made you the appropriate person for pricing and arbitrage in crypto?

BANKMAN-FRIED: Yeah, there’s probably some truth to that. [laughs]

Here is the full dialogue.

The wisdom of David Brooks

Performative populism has begun to ebb. Twitter doesn’t have the hold on the media class it had two years ago. Peak wokeness has passed. There seem to be fewer cancellations recently, and less intellectual intimidation. I was a skeptic of the Jan. 6 committee at first, but I now recognize it’s played an important cultural role. That committee forced America to look into the abyss, to see the nihilistic violence that lay at the heart of Trumpian populism.

Here is the full NYT column.  Wise throughout.

The Folk Economics of Housing is Folked Up

When confronted with a puzzle, economists instintively look for an explanation based on the incentives of rational people acting within institutional constraints. The economic approach is humble–rather than assuming that something is wrong with other people, the economists begins to unravel a puzzle by assuming that there is something the economist doesn’t understand. The economic approach is respectful of other people’s preferences and the constraints that they operate under. The economic approach is egalitarian, it looks for an answer that amounts to, “ah, now that I understand this, if I were in the same position I would do as these people are doing.”  The economic approach is powerful but it can be taken too far. Sometimes people aren’t rational. As Larry Summer said, “There are idiots. Look around.” 

In Folk Economics and the Persistence of Political Opposition to New Housing Clayton Nall, Chris Elmendorf, and Stan Oklobdzija look around at the housing market and declare there are idiots. Well, they are more polite but that’s the gist. Did we really need a 96 page paper to tell us this? Well, I didn’t. I was convinced of the problem years ago when after giving a rational explanation of why it’s difficult to get new housing approved, Bryan Caplan remarked wryly “yeah, that’s all true but renters are also opposed to new housing!” What this paper shows is that Bryan was right and that it matters.

Using two nationally representative surveys of urban and suburban residents, with embedded experiments, we show that about 30%-40% of Americans believe, contrary to basic economic theory and robust empirical evidence, that a large, exogenous increase in their region’s housing stock would cause rents and home prices to rise. This finding is robust to variations in the source of the supply shock, the manner in which price predictions are elicited, and the stated assumptions about counterfactual future prices in the absence of the shock. Moreover, by comparing homeowners and renters, by relating price predictions to self-reported confidence in the prediction, by comparing the predicted effects of more- and less-popular supply-shock scenarios, and by exploiting a survey experiment, we are able to discount motivated reasoning or guessing as explanations for these responses.

The authors do have new results which I wouldn’t have predicted. People are idiots about housing especially but not about rutabagas.

Housing “Supply Skepticism” is not just a manifestation of general economic ignorance. We show that the public understands the implications of supply and demand in markets for agricultural commodities, for labor, and even for cars, a durable consumer good that, like housing, trades in new and second-hand markets. There is also overwhelming agreement about how home prices and rents are locally affected by changes in neighborhood quality, by in-migration of rich people, by expansions of employment, by demolition of affordable homes, by new construction of expensive housing next door to more affordable homes, and (perhaps more questionably) by corporate ownership.

A deep problem is that people tend to blame developers of housing for high prices, i.e. they blame high prices on the one group most responsible for lowering prices! We see the same thing in other markets, of course, but in housing this effect appears especially strong.

…we observe a very strong tendency to blame housing providers (developers) for high housing prices. Conversely, actors whose stock in trade is opposing new development (environmentalists, anti-development activists) are almost never blamed. Incumbent owners who rent out their property (landlords) are commonly blamed, whereas incumbent owners who occupy it (homeowners) are not, even though both groups have a similar economic interest in supply restrictions. The pattern of blame attribution is very similar for homeowners and renters, except that renters hold landlords more responsible and homeowners are slightly more likely to list developers in their top three.

Addendum: Lots of folks are commenting in the comments.

*Hayek: A Life, 1899-1950*, by Bruce Caldwell & Hansjoerg Klausinger

One of the best biographies of any economist, covers anything you might wish to know, and with conceptual understanding.  This is a fantastic book and I am eagerly awaiting volume II.  Mini-excerpt:

Hayek [at LSE] never really liked Mannheim, whom he spent some time with when he first arrived, trying to introduce him around and help him to get acclimated.  This ended when, after listening patiently to Mannheim complain about the inadequacy of the English language for expressing his ideas, Hayek finally blurted out, “So much the worse for your ideas!”

You can pre-order here.  Hayek, by the way, is an interesting polar case for any talent search algorithm.  He was first interested in botany, and didn’t do anything in economics until he was 30 years old.

And I hadn’t known that Colette was the stepmother of Bertrand de Jouvenal (“On Power”), and had a five-year affair with him!

The persistence of Jim Crow effects

This paper studies the long-run effects of slavery and Jim Crow on Black Americans’ economic outcomes. We trace each Black family’s linked census and administrative records between 1850 and 2000 to measure how long they were enslaved and where they lived during Jim Crow. We show that Black families who were enslaved until the Civil War have considerably lower education, income, and wealth today than Black families who were free before the Civil War. The disparities between the two groups have persisted because most families enslaved until the Civil War lived in states with strict Jim Crow regimes after slavery. In a regression discontinuity design based on ancestors’ enslavement location, we show that states’ Jim Crow regimes sharply reduced Black families’ economic progress in the long run, largely by limiting their access to education. Using quasi-experimental variation, we show that gaining school access closed 80 percent of the gap in human capital caused by exposure to strict Jim Crow regimes.

That is from a new paper by Lukas Althoff and Hugo Reichardt.  Althoff is on the job market from Princeton, Reichardt is a third-year student from LSE.  Also a reminder that Garett Jones’s new book on Deep Roots, The Culture Transplant, is about to come out…

Is a Russian price cap a good idea?

That is the topic of my latest Bloomberg column.  Here is the basic idea:

Say the price of oil is $100 per barrel, and extraction costs Russia $50 per barrel. The profit on that oil is $50 per barrel. Now assume a price cap of $70 per barrel. Russian profit falls to $20 per barrel — but still, the oil will be produced. A finely tuned price control would redistribute income toward buyers of Russian oil, without much interfering with oil supply.

Enforcement would have to be through maritime services, such as insurance for the carrying ships.

But I am not sold on its workability or efficacy:

One problem is how to set the cap at the right level. The plan is to set a fixed cap, rather than at some percentage discount to world oil prices. As world oil prices change, it would therefore be necessary to adjust the cap, preferably quickly. Given that it has taken months to agree to the idea of a cap, it remains to be seen if this would be possible. And things only get worse if the Western coalition against Russia splinters, or if the relevant bureaucracies are slow.

If the price cap ends up too low and Russian oil is taken off world markets altogether, that could significantly worsen what is already a serious global economic downturn.

A second problem is that Russia might simply sell the oil to nations not participating in this agreement to cap prices, most notably China and India. But selling more to those countries might require Russia to lower the price. And while China and India are unlikely to join the G-7 plan, the very existence of the price cap gives them bargaining leverage over Russia.

The bottom line, however, remains: Any decline in Russian government revenue might be considerably less than what a plan to cap the price of oil might indicate. And that’s not even considering whatever Russia might earn from selling oil on the black market. Nations outside the G-7 would have an incentive to buy tankers, self-insure them and use them to ship Russian oil without the price cap.

But the major issue is one of escalation…

In any case worth a ponder, there are further arguments in the piece.

My criticism of the Diamond-Dybvig model

I think I forgot to mention this when they won the Nobel Prize.  In their model of bank runs, there are multiple equilibria and people can run on the bank simply if they expect other depositors will run on the bank too.  The combination of liquid liabilities and illiquid assets then means the bank cannot meet all their claims.  That is logically consistent, but I think not realistic.  Virtually all the bank runs I know of stem from insolvency, not rumors, noise, and multiple equilibria.  Didn’t Hugh Rockoff do some papers showing that the “free banking era” bank runs were pretty rational in the sense that the depositors targeted the right institutions?  Or did someone other than Rockoff do this work?  In any case, I’ve long thought that bank run models based on insolvency are more useful than bank run models based on rumors and multiple equilibria.
