AI Worship
i expect ai to be capable of superhuman persuasion well before it is superhuman at general intelligence, which may lead to some very strange outcomes.
Sam Altman on Twitter. Clearly true.
I predict AI driven religions. At first these will begin as apps like, what would Jesus say? But the apps will quickly morph into talk to Jesus/Mohammed/Ram. Personal Jesus. Personal Ram. Personal Tyler. Then the AIs will start to generate new views from old texts. The human religious authorities will be out debated by the AIs so many people will come to see the new views as not heretical but closer to God than the old views. Fusion and fission religions will be born. As the AIs explore the space of religious views at accelerated pace, evolution will push into weirder and weirder mind niches.
What strange outcomes do you predict?
Google searches for inequality (from my email)
From Jared Sleeper:
I was surprised to see this magnitude of effect. Google searches for “inequality” are twice as high during the academic year as they are during the summer. They double in September vs. August and then collapse by 50% in June vs. May.
What is it we do and do not know about macroeconomics?
That is the topic of my latest Bloomberg column, here is one excerpt:
Another episode frequently cited as evidence against economists is the Great Recession of 2007-2009. Economists did make some mistakes on that one — but they are not the ones you usually hear about.
When real estate prices started to slow down and then fall, many economists declared there was a real estate bubble. The theory quickly developed that the market crash was due to a real estate bubble bursting, followed by a sharp fall in aggregate demand, followed by a decline in employment and output.
The last part of that explanation is correct. In retrospect, however, it is not clear that the housing prices of 2006-2007 represented a bubble. By today’s metrics those prices appear prescient, if slightly premature. The market was suddenly realizing that a lot of real estate assets were going to be worth much more — and the recent evolution of real estate valuations seems to have confirmed that judgment.
In 2009, however — and following a lot of foreclosures and the emergence of troubled banks — the market was far from ready to accept that the high real estate prices had been justified. The market was too skeptical when it should have been less panicked. A lot of economists got this wrong too, along with many pundits. All of this made the resulting panic worse because the talk was so pessimistic about real estate valuations. Instead, the real problem was that the market had lost faith in a set of high real estate prices that has since been largely validated. Maybe not in Las Vegas and Orlando, but for the nation as a whole, most of all on the coasts.
Economists should have been less quick to judge what is or is not a bubble. The real-estate-bubble explanation appeared to be correct in the short run, but economists should have been more modest about their ability to second-guess the market. The good news is that, with hindsight, we can piece together what happened. Policymakers and market participants made a series of overlapping mistakes related to monetary policy, the shadow banking system and panic about real estate.
There is a good picture of trends in real estate prices at the link, or ungated here.
Rooftops, people
We find that consumer surplus is the primary component of social impact (dwarfing profits, worker surplus, and externalities), suggesting that consumer impacts deserve more attention from impact investors. Existing ESG and social impact ratings are essentially unrelated to our economically grounded measures.
That is from a new NBER working paper by Hunt Allcott, Giovanni Montanari, Bora Ozaltun, and Brandon Tan.
What did the different great economists think about India?
One feature of my new generative book GOAT: Who is the Greatest Economist of All Time and Why Does It Matter? is that almost all of the major contenders (save Hayek) considered India and wrote about India. I compare and contrast the different treatments, as this is one test of how good an economist you are: can you make sense of a very new and different environment?
From the text, written by me, here is Milton Friedman on India:
Let’s consider Milton Friedman’s 1955 memo written to the government of India, based upon his first trip there. No one ever has suggested that Friedman was an expert on India, or even an expert on developing nations, a topic that barely came up in his published research (he does discuss Hong Kong and the other Asian tigers in some of his more popular writings).
Friedman starts the memo by noting that a five percent rate of economic growth should be possible for India, reflecting of course his interest in economic progress. That was during a time when Indian growth rates were more in the range of two percent, and the prevailing approach was to refer to “the Hindu rate of growth” in a pessimistic manner. Friedman also suggests that Indian growth will be “catch-up growth,” drawing upon the “technical and scientific knowledge” of the world. Early on in the memo, Friedman also argues for a moderately expansionary monetary policy, much better education and training, and better infrastructure.
So far Friedman is on track.
He presents further specifics when confronting other views. For instance, he argued that the prevailing development literature put too much emphasis on aggregate investment and the capital to output ratio. Friedman worried about the possibility of malinvestment, and that the Indian government would favor “heavy industry…and handicrafts” too much, at the expense of small and medium-size enterprises. Furthermore, he saw that India should focus more on human capital.
Friedman also insists that the Indian government should not excessively expand the public sector. He criticized “nationalization and detailed state control over economic activity,” hardly a surprising view from Milton Friedman. You might see this point as overlooking the possibility of East Asian-style industrial policy, but Indian government interventions, during this period and afterwards, did turn out relatively badly, and furthermore the East Asian successes were hardly apparent or even existing at the time. So Friedman’s analysis may be imperfect in hindsight, but overall it was defensible. Nonetheless Friedman could have raised the importance of an economy having sectors with increasing returns, learning effects, and higher growth potential, but he did not. Most of all, he was appropriately critical of the efforts of the Indian government to protect inefficient industries, and he attacked licensing requirements and the general stifling of progress through excess regulation and favoritism.
Friedman also called for India to have money supply growth of 4 to 6 percent a year, and he placed special stress on this recommendation. My view is a little different, having observed that South Korea often had high double-digit inflation during its economic miracle, but still this was sound enough advice, even if he overly prioritized the point.
On the tax side, Friedman called for a broader tax base for India with a greater scope for direct income taxation. Excise taxes, in turn, should be cut back. These recommendations also have held up well, and furthermore they belie the view of Friedman as a mindless tax cutter.
In his notes on Indian economic planning, Friedman expressed concern that the distribution of income in India was widening rather than narrowing. He also takes pains to rebut the view that India is culturally or religiously unsuited for economic growth, and he blames poor Indian economic policy for India’s poverty, not the Indian people. To the current reader, this sharp distinction between culture and ideas about policy may sound naïve, especially since Friedman complains about both corruption and the fondness of Indian intellectuals for socialist ideology. Do those two factors truly have nothing to do with the culture of a country or region? In any case Friedman saw the very great potential in India.
He also criticized India’s system of foreign exchange allocation and called for a freeing up of capital markets and exchange rates. Arguably the verdict on this recommendation is still out, as India still controls capital flows and thus its exchange rate to some extent. Some defenders of this policy will argue it is why India has avoided a major financial crisis, namely that international capital flows in and out of the country never have been so volatile. Again, while I tend to agree with Friedman here (there is evidence that foreign capital significantly boosts Indian productivity), I would acknowledge this as a possible point of criticism. At the very least it is not obvious that Friedman was correct in this segment of his recommendations.
Finally, Friedman closes the memo by noting he has focused so much on monetary and financial affairs because that is his area of expertise. He also notes a few times that he is no expert on the economic affairs of India.
In sum, this memo is not perfect…but it basically hits the mark, has held up well, and Milton Friedman passes the test of giving good policy advice into a broadly unfamiliar situation.
You will find the endnotes in the core text. Of course Smith, Malthus, Mill, and Keynes also dealt with India, with varying degrees of success. The import of India for the history of political economy remains a wee bit underrated.
U.S.A.-Europe facts of the day
The U.S. government Friday said its deficit rose to $1.7 trillion, or 6.3% of gross domestic product, in the year ended Sept. 30, from $1.4 trillion, or 5.4% of GDP, a year earlier. Without an accounting change related to the administration’s aborted student-loan-cancellation program, the deficit would have been closer to $2 trillion, a doubling from the prior year.
In projections released earlier this month, the International Monetary Fund projects U.S. deficits for all governments will reach 7.4% of GDP in 2024 and 2025.
But in Europe it is a different picture. The IMF expects combined deficits of eurozone governments will fall to 3.4% of GDP this year from 3.6% in 2022, and further to 2.7% in 2024.
Those countries that were in crisis a decade ago are expected to have much smaller budget gaps. In Greece, the deficit is forecast to fall to 1.6% of GDP from 2.3% last year, while Portugal’s is expected to fall to 0.2% of GDP from 0.4%. Ireland is forecast to have a budget surplus for the second straight year. Italy and France, among others, continue to have deficits of roughly 5% of GDP.

“Does Paid Sick Leave Facilitate Reproductive Choice?”
I might give the paper a slightly different title, but:
Unlike most advanced countries, the U.S. does not have a federal paid sick leave (PSL) policy; however, multiple states have adopted PSL mandates. PSL can facilitate healthcare use among women of child−bearing ages, including use of family planning services such as contraception, in−vitro fertilization, or abortion services. Use of these services, in turn, can increase or decrease birth rates. We combine administrative and survey data with difference-in-differences methods to shed light on these possibilities. Our findings indicate that state PSL mandates reduce birth rates, potentially through increased use of contraception but not changes in abortion services. We offer suggestive evidence of heterogeneity in birth rate effects by age, education, and race. Our findings imply that PSL policies may help women balance family and work responsibilities, and facilitate their reproductive choices.
That is a new NBER working paper by Johanna Catherine, Maclean, Ioana Popovici, and Christopher J. Ruhm.

But financial markets have mostly been subdued in reaction to the conflagration brewing in Gaza. The benchmark US S&P 500 index has barely budged since the Hamas attack on October 7. Even stock markets closest to the battle zone, from Saudi Arabia to Egypt and the Gulf states, have experienced moderate pullbacks. There has been no rush to safety in bond markets, where prices have been falling, and little drama in oil prices either.

*GOAT: Who is the Greatest Economist of all Time, and Why Does it Matter?*
I am pleased to announce and present my new project, available here, free of charge. It is derived from a 100,000 word manuscript, entirely written by me, and is well described by the title of this blog post.
I believe this is the first major work published in GPT-4, Claude 2, and some other services to come. I call it a generative book. From the project’s home page:
Do you yearn for something more than a book? And yet still love books? How about a book you can query, and it will answer away to your heart’s content? How about a book that will create its own content, on demand, or allow you to rewrite it? A book that will tell you why it is (sometimes) wrong?
To be clear, if you’re not into generative AI, you can just download the work onto your Kindle, print it out, or read it on a computer screen. Yet I hope you do more:
One easy place to start is with our own chatbot using GPT-4, and we’ll soon provide custom apps using Claude 2 and Llama 2. In the meantime we’ve provided instructions for how to experiment with them yourself.
Each service has different strengths and you should try more than one. You’ll see the very best performance by working with individual chapters using your own subscription to ChatGPT, Claude, or a similar service. The chapters can be read independently and in any order. Ask the AI if you’re lacking context. Try these sample questions to start.
You can ask it to summarize, ask it for more context, ask for a multiple choice exam on the contents, make an illustrated book out of a chapter, or ask it where I am totally wrong in my views. You could try starting with these sample questions. The limits are up to you.
Here is the Table of Contents:
1. Introduction
2. Milton Friedman
3. John Maynard Keynes
4. Friedrich A. Hayek
5. Those who did not make the short list: Marshall, Samuelson, Arrow, Becker, and Schumpeter
6. John Stuart Mill
7. Thomas Robert Malthus
8. Adam Smith
9. The winner(s): so who is the greatest economist of all time?
The site address is an easy to remember econgoat.ai. And as you will see from the opening chapter, it is not only about economics, it is also a very personal book about me. No Straussian here, I tell you exactly what I think, including of my personal meetings with Friedman and Hayek. If, however, you are looking for a Straussian reading of this project — which I would disavow — it is that I am sacrificing “what would have been a normal book” to the AI gods to win their favor.
And apologies in advance for any imperfections in the technology — generative books can only get better.

A Taxonomy of Methods for Discriminating, Revisited
Twenty years ago, GMU law professor Lloyd Cohen (RIP) guest blogged at MR. His taxonomy of methods of discrimination in university admissions remains timely. What follow is from Lloyd (I have added only the two links). No indent.
—
Not all procedures for engaging in racial discrimination are equal. They differ in their legal standing, their social meaning, and their “economic” efficiency. The Supreme Court in distinguishing Grutter and Graatz, and the admissions regimes of the various state universities suggest a useful taxonomy.
There are three generic forms of racial discrimination not merely in admissions decisions but in other practices and policies as well: (1) express and objective (i.e., points and quotas); (2) facially neutral and objective (e.g., the top 10% of graduates from each high school); and (3) implied and subjective (“we look at the whole person”). From an efficiency perspective the first form of discrimination is the least harmful. It does not corrupt the measure of merit, it only sets a different standard for “minorities.” Its shortcomings are twofold. First, as the Supreme Court decisions in Grutter and Grattz makes abundantly clear it is the one method most likely to be found illegal. This is implicitly related to its second shortcoming, it is so barefaced. It makes clear to both those favored and those harmed that the favored are otherwise inferior in their qualifications.
The second method, using a facially neutral operational measure to achieve a suspect theoretical goal, now favored by the state universities of California, Texas and Florida, in granting admission to those who finish in the top X% of their high school class and by the United Network for Organ Sharing in granting more “points” in the organ allocation scheme for time on the waiting list, has the virtue of being an objective measure, and the virtue (?) of a disguise that reduces shame. Its shortcoming is that its effectiveness in bringing about the preferred ethnic distribution is tied to its inefficiency. It employs an objective measure of merit that substantially distorts. Thus, the rankings of both the favored and the unfavored groups are mis-aligned.
The third measure, a subjective, ad-hoc eclectic judgment, can in practice be a mimic of the first, the second, or anything else. The process becomes a beclouded mystery. This is both its virtue and its vice. There is no clear trail, evidence or standards that mark the favored as inferior–feelings are spared. On the other hand the absence of an objective measure means that the decisionmakers are effectively unanswerable and may indulge in any form of corruption.
Method (1) is clearly falling by the wayside. Is there likely to be a clear political winner between (2) and (3)?
What should I ask Ami Vitale?
Yes I am doing a Conversation with her. From Wikipedia:
Ami Vitale is an American photojournalist, documentary filmmaker, educator and speaker. In 2018, she published a photo book titled Panda Love which captures pandas within captivity and being released into the wild…
In 1994, Vitale joined the Associated Press (AP) as a picture editor in New York and Washington, D.C.[5][6] She self funded her travel through her work with AP and left for the Czech Republic in 1997.
She moved to Prague, Czech Republic, and spent a year covering the war in Kosovo, traveling back and forth to Prague, and spending a month at a time in the war zone. She later traveled to Angola, and then to the second Intifada in Gaza and Israel. In 2000, she received an Alexia Foundation grant to document a small village in the West African nation of Guinea Bissau.
Vitale currently photographs wildlife and environmental stories in order to educate about global conservation issues. She is a visual journalist working as a photographer for National Geographic, a documentary filmmaker, and a cinematographer. Her recent still photography focuses on wildlife conservation in Africa, the Middle East, and Asia. As an ambassador for Nikon and a contract photographer with National Geographic magazine, she has documented wildlife and poaching in Africa, covered human-wildlife conflict, and concentrated on efforts to save the northern white rhino and reintroduce pandas to the wild.
She has traveled to more than one hundred countries. Here is her home page, which includes links to her documentaries. Here is her Instagram.
So what should I ask her?

*The Women Who Made Modern Economics*
By Rachel Reeves. Here is the U.S. Amazon listing, but even the Kindle version is not actually available. Here is the UK Amazon listing. Here is a Times of London review of the book: “They [the book’s subjects] range from Beatrice Webb, who, as a founder of the LSE, is a natural choice, to Rosa Luxemburg, the revolutionary Marxist, and Dambisa Moyo, the international aid theorist elevated to the Lords by Boris Johnson.” Note that Reeves is also Shadow Chancellor of the Exchequer, and thus surely worthy of getting U.S. book distribution?
