School workbooks recommendation

I’m on my second book in a series of age-appropriate Brain Quest academic workbooks. Here’s a link to the summer book for 2nd to 3rd grade.

These workbooks are well designed. I’m not promising that your kids will not see it as a chore, but I think these books make practicing math and writing about as fun as it can be.

We found Brain Quest in a bookstore while we were looking for things to do in my son’s summer after kindergarten. The K-to- 1 summer workbook was fun and helped maintain what he had learned in kindergarten. He loved adding a new sticker to the adventure path after finishing each activity. You can finish it in one summer by doing about 5 pages per day, which only takes about 10 minutes.

We really love the summer map books but they also have schoolyear books. The First Grade school-year book is huge (320 pages). There aren’t as many stickers as the K-to-1, but they still have a way of marking off accomplishments that my son finds satisfying. It’s a kind of gamification, but it’s not more screen time.

These pages can be done after school on weekdays. What I like best is that it gives us some structure to leaning on weekends and holidays. It’s cheaper than tutoring.

Russia, The US, and Crude Data

Overall, I’ve been disappointed with the reporting on the US embargo against Russian oil. The AP reported that the US imports 8% of Russia’s crude oil exports. But then they and other outlets list a litany of other figures without any context for relative magnitudes. Let’s shine some more light on the crude oil data.*

First, the 8% figure is correct – or, at least it was correct as of December of 2021. The below figure charts the last 7 years of total Russian crude oil exports, US imports of Russian crude oil, and the proportion that US imports compose.  That 8% figure is by no means representative of recent history. The average US proportion in 2015-2018 was 7.8%. But the US share as since risen in level and volatility. Since 2019, the US imports compose an average of 11.9% of all Russian crude oil exports.

As an exogenous shock, the import ban on Russian crude oil might have a substantial impact on Russian exports. However, many of the world’s oil importers were already refusing Russian crude. The US ban may not have a large independent effect on Russian sales and may be a case of congress endorsing a policy that’s already in place voluntarily.

FTX Future Fund

Crypto is a lot of things- a store of value, a means of payment, a building block for other tools on the web. But while much of its value as a tool is yet to be realized, one big effect we see already is that it has made a lot of nerds very rich very young, even by the standards of tech and finance generally. These newly minted millionaires and billionaires have started giving their money away in very different ways than the traditional older philanthropists.

The latest, and I believe biggest example is the FTX Future Fund. It plans to give away at least $100 million this year, funded primarily by 30-year-old Sam Bankman-Fried, the CEO of crypto exchange FTX. I recommend that everyone read their full list of the 35 types of projects that they’d like to fund, but I’ll highlight a few you wouldn’t see from older foundations:

Demonstrate the ability to rapidly scale food production in the case of nuclear winter

Biorisk and Recovery from Catastrophe

In addition to quickly killing hundreds of millions of people, a nuclear war could cause nuclear winter and stunt agricultural production due to blocking sunlight for years. We’re interested in funding demonstration projects that are part of an end-to-end operational plan for scaling backup food production and feed the world in the event of such a catastrophe. Thanks to Dave Denkenberger and ALLFED for inspiring this idea

Prediction markets

Epistemic Institutions

We’re excited about new prediction market platforms that can acquire regulatory approval and widespread usage. We’re especially keen if these platforms include key questions relevant to our priority areas, such as questions about the future trajectory of AI development.

Critiquing our approach

Research That Can Help Us Improve

We’d love to fund research that changes our worldview—for example, by highlighting a billion-dollar cause area we are missing—or significantly narrows down our range of uncertainty. We’d also be excited to fund research that tries to identify mistakes in our reasoning or approach, or in the reasoning or approach of effective altruism or longtermism more generally.

They also seem to be borrowing some of Tyler Cowen’s approach to Fast Grants and Emergent Ventures- the application is relatively short and simple, and they promise response times that will be measured in weeks, rather than the months or years typical of large funders.

But they expect applicants to be fast too- this fund was just announced a few days ago, and applications are due March 21st. Economists will be natural fits for some of their project ideas, since their areas of interest include “economic growth” and “epistemic institutions”. I’ll be applying with my book project on why US health care spending is so high. But they are clearly casting a wide net to find the best ideas, so I encourage everyone to check it out and consider applying.

Gas Prices are High — But Don’t Adjust Them for Inflation!

Gasoline prices are high and rising. Anecdotally, they seem to be increasing at the pump by the hour. And indeed, in nominal terms they are now the highest they have ever been in the US (this is true with both the AAA daily price level and the EIA weekly price level). At over $4.10 per gallon, the price now exceeds the peaks briefly hit in 2008, 2011, and 2012. And it’s looking like this peak might not be so brief.

But we all know you can’t compare nominal dollars over long periods of time. We need some context for this price! Plenty of news stories provide what they think is the right context: adjust it for inflation! For example, USA Today reports that today’s price “would come to around $5.25 today when adjusted for inflation.”

$5.25: that’s a pretty concrete number. But it’s not really useful. OK, so clearly that’s higher than the current price, about 20% higher in fact. Still, it doesn’t really give us the right context.

As I argued in a previous post on housing costs, inflation adjustments aren’t always the best way to contextualize a historical number. Yes, when you want to compare income or wages over time, it’s good to adjust for inflation. It’s necessary, in fact. And a good economist will always do that.

However, when comparing particular prices over time, it doesn’t really make sense to adjust for other prices. All you are really saying is “if the price of gasoline increased at the same rate as the average price level, here’s what it would be.” Perhaps slightly useful, but it doesn’t really get at the thing we’re really try to address: is gasoline more or less affordable than in the past?

The best approach is to adjust the prices for changes in wages or income. Which measure of wages or income you choose is important, but it’s the best adjustment to make. No need to make any inflation adjustments, are worrying about whether the index you choose is properly accounting for quality changes, substitution effects, etc. If you want to know how affordable something is, compare it to income.

Here’s what I think is the best simple comparison for gasoline, which I’ll explain it below. In short, it tells us how many minutes the average worker would need to work to purchase one gallon of gasoline.

Since the price of gasoline is rising sharply every day lately, my chart will surely be out of date very soon. But right now, it’s the most current data I could provide with a comparable historical series: EIA weekly data current through March 7th, 2022 (Monday). We can see that at current prices, it takes about 9 minutes of work at the average wage to purchase a gallon of gasoline. At the peak in 2008, it took over 13 minutes of work to purchase a gallon, and it fluctuated between 10 and 12 minutes of work for much of 2011-2014.

How Overzealous Green Policies Force Europe to Bankroll Putin’s Military

There is a difference between healthy zeal for a basically good cause like reducing CO2 emissions, and unbalanced myopia. Back in September I wrote about the European power debacle (skyrocketing gas and electricity prices):

Shut down your old reliable coal and nuclear power plants. Replace them with wind turbines. Count on natural gas fueled power plants to fill in when the breeze stops blowing. Curtail drilling for your own natural gas, and so become dependent on gas supplied by pipeline from Russia or by tankers chugging thousands of miles from the Middle East. What could possibly go wrong?

Well, now we know what can go wrong.

In January I noted more specifically, “This energy shortage also makes Europe very vulnerable to Russia, at a time when Putin is menacing Ukraine with invasion.” Now it has come to pass. All the huffing and puffing about economic sanctions on Russia is mainly just hot air. Because Europe is utterly dependent on Russian gas, massive “carve-outs” have been made in sanctions in order to continue these purchases to continue. The vaunted SWIFT restrictions on Russian banks have been carved down to practical irrelevance. While sanctions may impact the lifestyles of oligarch playboys, this flow of euros to Russia ensures that Putin will not run short of money for his war.

Ecomodernist Michael Shellenberger writes that behind the Ukraine military drama “is a story about material reality and basic economics—two things that Putin seems to understand far better than his counterparts in the free world and especially in Europe.” Shellenberger asks, “How is it possible that European countries, Germany especially, allowed themselves to become so dependent on an authoritarian country over the 30 years since the end of the Cold War?” and then answers this question in his trademark style:

Here’s how: These countries are in the grips of a delusional ideology that makes them incapable of understanding the hard realities of energy production. Green ideology insists we don’t need nuclear and that we don’t need fracking. It insists that it’s just a matter of will and money to switch to all-renewables—and fast. It insists that we need “degrowth” of the economy, and that we face looming human “extinction.” (I would know. I myself was once a true believer.)

… While Putin expanded Russia’s oil production, expanded natural gas production, and then doubled nuclear energy production to allow more exports of its precious gas, Europe, led by Germany, shut down its nuclear power plants, closed gas fields, and refused to develop more through advanced methods like fracking.

The numbers tell the story best. In 2016, 30 percent of the natural gas consumed by the European Union came from Russia. In 2018, that figure jumped to 40 percent. By 2020, it was nearly 44 percent, and by early 2021, it was nearly 47 percent.

…The result has been the worst global energy crisis since 1973, driving prices for electricity and gasoline higher around the world. It is a crisis, fundamentally, of inadequate supply. But the scarcity is entirely manufactured.

Europeans—led by figures like Greta Thunberg and European Green Party leaders, and supported by Americans like John Kerry—believed that a healthy relationship with the Earth requires making energy scarce. By turning to renewables, they would show the world how to live without harming the planet. But this was a pipe dream. You can’t power a whole grid with solar and wind, because the sun and the wind are inconstant, and currently existing batteries aren’t even cheap enough to store large quantities of electricity overnight, much less across whole seasons.

In service to green ideology, they made the perfect the enemy of the good—and of Ukraine.

There we have it.  It’s not just the Europeans. As I write this, shells are raining down on Ukrainian cities but the U.S. is not restricting its imports of Russian oil, lest our price of oil go even higher. The present oil shortage (even before the Ukraine invasion) is what happens when a president on his first day in office signs an executive order to cancel a pipeline expansion which would have enabled increased oil production from Canada’s massive oil sands, and the whole ESG movement hates on investing in projects for producing oil or gas.

All that said, what the West gives with one hand it may take back with the other. Although energy exports from Russia are theoretically permitted, Western private enterprises, including finance arms, are pulling back from any dealings with Russia. This means in practice, lots of wrenches are being thrown into the machinery of international finance, such that energy exports from Russia are being slowed, though not stopped. But in turn, the Russians are getting higher prices per barrel for the oil that does get exported. There are many moving parts to all this, so we will see how it all shakes out.

All good Bayesians should donate to the Ukraine today

The Kyiv department of economics has created what appears to be a vetted and relatively efficient channel for donating to the care of the Ukraine people during this crisis. You can donate via credit card or crypto. This is very much one of those cases where I believe every little bit helps. Consider:

  1. Russia planning and logistical failures mean a continuing heavy invasion may not be sustainable, leading instead to a long runing siege. If this is the case, then it becomes all the more important to get basic humanitarian resources in now in order to minimize the suffering caused by the siege and minimize the odds of Russian success.
  2. Ukrainian resistance depends as much on morale as it does lethal resources. Knowing their families are fed and receiving basic healthcare is critical.
  3. If the micro-returns protecting a Ukrainian soldier or feeding a Ukrainian family aren’t enough for you, here’s a macro one: if the autocratic leader of an increasingly fascist regime with the strategic advantage of a nuclear arsenal is rebuffed in the Ukraine by a heroic local resistance partnered by global economic sanctions, it will serve as a signal to every leader with similar aspirations that success is less likely than they previously estimated. If your donation can help force a Bayesian update on dangerous autocrats and strongmen everywhere, that seems like nothing less than a perfectly rational act of utility maximization to me.

Subtle ways to sneak in rationality

Generally, when you do your microeconomics class you get to see isoquants. I mean, I hope you get to see them (some principles class dont introduce them and are left to intermediate classes). But when you do, they look like this:

Its a pretty conventional approach. However, there is a neat article in History of Political Economy by Peter Lloyd (2012) titled “the discovery of the isoquant“. The paper assigns the original idea, rather than to the usual suspect of Abba Lerner in 1933, to W.E. Johnson in 1913 as A.L. Bowley was referring to his “isoquant” in a work dated from 1924 (from which the image is drawn). But what is more interesting that the originator of the idea is how the idea has morphed from another of its early formulations. In the 1920s and 1930s, Ragnar Frisch was teaching his price theory classes in Norway and depicted isoquants in the following manner in his lectures notes.

Do you notice something different about Frisch’s 1929 (or 1930) lectures relative to the usual isoquants we know and love today? Watch the end of each isoquant. They seem to “arc” do they not? How could an isoquant have such a bent? Most economists are probably so used to using isoquants that do not bend (except for perfect complements) that it will take a minute to answer. Well, here is the answer: its because Frisch was assuming that the production function from which the isoquant is derived had a maximum which means that the marginal product of an input could become negative. This is in stark contrast with our usual way to assume production functions as smoothly declining (but never negative) marginal products. This is why Frisch includes an arc to this shape (a backward bend).

Why did we move away from Frisch’s depiction? Well think about the economic meaning of a negative meaning marginal product. It means that a firm would be better off scaling down production regardless of anything else. Its a straightforward proposition to understand why in all settings, a firm would automatically from such an “uneconomic” zone. In other words, we should never expect firms to continually operate in a zone of negative marginal product. Ergo, the “bend”/”arc” is economically trivial or irrelevant. Removing it simplifies the discussion and formulation but also does something subtle — it sneaks in a claim rationality of behavior from firmowners and operators.

This is a good setup for a question to ask your students in an advanced microeconomics class that isnt just about the mathematics but about what the mathematical formulations mean economically!

The War on Ukraine

1. Read this letter from a young woman inside of Russia. Her despair is not sadder than the Kindergarten getting bombed, but it helps explain why people are resisting Russian rule. Ukrainians’ lives would be like hers except worse.

2. ‘My city’s being shelled, but mum won’t believe me’ With loyalty like this, I don’t understand why Russian state TV is bothering to cover up the shelling. Mum’s personal loyalty to Putin already transcends her love of her own daughter. Is lying itself a flex and a form of psychological warfare against the opposition within Russia?

3. Read on the End of History, and my blog about circular history.

4. Social media changes sieges.

5. President Putin speaks his truth, embraces his identity, and blocks his haters. With a trifecta like that, I have no doubt that he practices self-care. And now people are upset that they can’t get through to rattle him. Now people wonder: why can’t we reason together anymore? Yet, this is what Americans are encouraging each other to do. We are out of practice when it comes to discovering and debating The truth.

Previously I wrote about Americans blocking each other on social media. Now when we want to get through to someone on the other side, we have less channels of communication open. Americans don’t get enough practice seeing the world through someone else’s eyes. We have gotten into a bad habit of curating our sources of information to insulate ourselves from the facts and opinions that would force us to learn or argue with someone who holds a different point of view.

Also, we are seeing many people cut ties with Russians. I understand, initially, why there was a blitz on all Russian people, as we tried to get through the news of what was happening with urgency. However, this next week might be an opportunity to reach out to an economist on the inside of Russia, if you know one. Should they be protesting on the street, instead of checking emails? At this point they have already made their decision. You could start a research project with them about some banal uncontroversial topic. They are going to suffer, regardless of whether they have a foreigner to talk to or not. This opens a channel.

(The faculty at Kyiv School of Economics is probably getting behind on their research. They would probably love it if you would look up their previously published papers. )

The percent of Russians who don’t agree with the war should be a concern to the Kremlin. Most of them will not openly say what they think within the borders of Russia, so it creates uncertainty. On paper, Russia is favored to be able to inflict more casualties, but this aspect of Russian society makes the future hard to model. Any young men who are sent to the front lines will learn what is actually happening from the Russian speakers in Ukraine. How will that affect them?

Two Decades of Real Estate Data

Total spending on real estate construction has been rising since 2011. By 2016 it had reached its previous 2006 peak. However, total spending on *residential* real estate construction didn’t reach its previous 2006 peak until November of 2020. The graph below also includes the proportion of residential construction spending (Green). It has been rising since 2009. In and of itself, nothing is good or bad about this figure. We might be spending less on non-residential construction because we are getting better at using less land per unit of good or service produced. Or, it could be that our real investment in future production is falling relative to our current residential consumption.  Regardless, the share of residential construction hasn’t been at this level since 2003.

Importantly, the difference in spending has not been driven by different construction costs. Both residential and non-residential construction costs have moved in tandem since 2010. Therefore, the rise in residential construction spending is not merely nominal – a greater proportion of resources are being consumed by residential construction. Indeed, real residential construction is up about 25% from 2019. The figure below illustrates real residential and nonresidential construction.

That figure requires a double-take.

Lessons from a Failed Merger

The two largest hospital systems in Rhode Island, Lifespan and Care New England, wanted to merge. I wrote previously that:

Basic economics tells us that if a company with 50% market share buys a company with 25% market share in the same industry, they have strong market power and are likely to use this monopoly position to raise prices…. I think the Federal Trade Commission will almost certainly challenge the merger, and that they will likely succeed in doing so

It turns out I was right about the FTC challenge, but wrong that it would be necessary. The same day that the FTC challenged the merger, Rhode Island Attorney General Neronha blocked it. The law in Rhode Island is such that he doesn’t need to convince a judge like the FTC would; the merger was done unless the parties tried to appeal. But today they gave up and officially terminated the merger.

I was surprised by the AG’s move because the merging parties have so much political clout in the state, and many politicians like Senator (and former RI AG) Whitehouse had expressed support for the merger. I expected that even if state leaders didn’t like the merger, they would approve it with the expectation that the FTC would step in and be the bad guy for them. So AG Neronha blocking the merger was a pleasant surprise.

I also said previously that the FTC might challenge the merger for creating a monopsony (predominant employer of health care workers) as well as a monopoly (predominant provider of hospital services). This turned out to be one vote short of true. The FTC voted 4-0 to challenge the merger, but released two concurring statements explaining why. The two Democratic commissioners wanted to challenge the merger on both monopoly and monopsony grounds, while the two Republican commissioners thought it would only be a monopoly. This didn’t matter for this case, since they all thought it would be a monopoly, and since the AG blocked it. It was also odd that the Democratic FTC commissioners were more worried about labor than the actual unions involved. But it may be a sign of more monopsony challenges to come, particularly once the vacant spot gets filled and a 3rd Democrat is breaking the ties.

This was the first big political / economic issue I’ve got involved in since moving to Rhode Island, and I have to admit I was worried about making enemies. But despite speaking against the merger at the same forum as its most powerful proponents, speaking to several journalists, and at the AG’s public forum, I didn’t hear a single angry response; if anything I made friends.

One final surprise in all this is that the two hospitals systems are reported to have spent $28 million pursuing the merger. Apparently money can’t buy everything. But what a lot to spend on something that so many of us thought was clearly destined to fail.
