Jason Furman on AI contestability
This ease of switching has forced companies to pass the gains from innovation on to users. Free tiers now offer capabilities that recently would have seemed almost unimaginable. OpenAI pioneered a $20-per-month subscription three years ago, a price point many competitors matched. That price has not changed, even as features and performance have improved substantially.
One recent analysis found that “GPT-4-equivalent performance now costs $0.40/million tokens versus $20 in late 2022.” That is the equivalent of a 70 percent annual deflation rate — remarkable by any standard, especially in a time when affordability has become a dominant public concern.
And this is only the foundational model layer. On top of it sits a sprawling ecosystem of consumer applications, enterprise tools, device integrations and start-ups aiming to serve niches as specific as gyms and hair salons.
Users aren’t the only ones switching. The people who work at these companies move from one to another, a sharp contrast to work in Silicon Valley during the era of do-not-poach agreements.
The entire NYT piece is very good.
One measure of economics GOAT
Who is the greatest economist of all time? This paper provides one potential measure that, along with other considerations, can contribute to debates on who the greatest economist of all time is. We build a novel dataset on the percentage of history of economic thought textbooks dedicated to top economists, using 43 distinct textbooks (1st editions, when available) published between 1901 and 2023. As a percentage of total book pages, Adam Smith has the highest share at 6.69%, beating out Ricardo (5.22%), Mill (3.83%), and Marx (4.36%). Just over 32% of all textbooks allocated most of their pages to Adam Smith, followed by Marx with 18.6%, Mill with 13.95%, and Ricardo with 11.3%. While interesting as a history of economic thought project, such an exercise isn’t merely amusing pedantry; it can provide insight into the types of contributions, research questions, and methodologies that have had the most enduring impact in economics. It may also inform future authors of history of economic textbooks.
That is from a new paper by Gabriel Benzecry and Daniel J. Smith. There is of course also my generative book on this topic at econgoat.ai.

“They” don’t want you to know this
Prompt:
Can a parent limit a kid’s screen time simply by tweaking some of the settings on the smart phone? Are these services available?
GPT Thinking answer:
Yes. On both iPhone and Android, a parent can limit a kid’s screen time largely through built-in settings (no extra app required), and there are also optional third-party services.

Public Finance in the Age of AI: A Primer
Transformative artificial intelligence (TAI) – machines capable of performing virtually all economically valuable work – may gradually erode the two main tax bases that underpin modern tax systems: labor income and human consumption. We examine optimal taxation across two stages of artificial intelligence (AI)-driven transformation. First, if AI displaces human labor, we find that consumption taxation may serve as a primary revenue instrument, with differential commodity taxation gaining renewed relevance as labor distortions lose their constraining role. In the second stage, as autonomous artificial general intelligence (AGI) systems both produce most economic value and absorb a growing share of resources, taxing human consumption may become an inadequate means of raising revenue. We show that the taxation of autonomous AGI systems can be framed as an optimal harvesting problem and find that the resulting tax rate on AGI depends on the rate at which humans discount the future. Our analysis provides a theoretically grounded approach to balancing efficiency and equity in the Age of AI. We also apply our insights to evaluate specific proposals such as taxes on robots, compute, and tokens, as well as sovereign wealth funds and windfall clauses.

“Tough on crime” is good for young men
Using data from hundreds of closely contested partisan elections from 2010 to 2019 and a vote share regression discontinuity design, we find that narrow election of a Republican prosecutor reduces all-cause mortality rates among young men ages 20 to 29 by 6.6%. This decline is driven predominantly by reductions in firearm-related deaths, including a large reduction in firearm homicide among Black men and a smaller reduction in firearm suicides and accidents primarily among White men. Mechanism analyses indicate that increased prison-based incapactation explains about one third of the effect among Black men and none of the effect among White men. Instead, the primary channel appears to be substantial increases in criminal conviction rates across racial groups and crime types, which then reduce firearm access through legal restrictions on gun ownership for the convicted.

The Macroeconomic Effects of Tariffs
We study the macroeconomic effects of tariff policy using U.S. historical data from 1840–2024. We construct a narrative series of plausibly exogenous tariff changes – based on major legislative actions, multilateral negotiations, and temporary surcharges – and use it as an instrument to identify a structural tariff shock. Tariff increases are contractionary: imports fall sharply, exports decline with a lag, and output and manufacturing activity drop persistently. The shock transmits through both supply and demand channels. Prices rise in the full sample but fall post-World War II, a pattern consistent with changes in the monetary policy response and with stronger international retaliation and reciprocity in the modern trade regime.

*Being and Time: An Annotated Translation*
Translated from the German by Cyril Welch.
Periodically I am asked if I have read Being and Time, and I always give the same response: “I have looked at every page.”
I also have spent time with it in German, though not for every page. But have I read it? Read it properly? Can anyone?
Is the book worth some study? Yes. But.
People, this volume is the best chance you are going to get.
Is there an aggregate demand problem in an AGI world?
No. Let’s say AI is improving very rapidly, and affecting the world more rapidly and more radically than I think is plausible. Let’s just say.
All of a sudden there are incredible things you can spend your money on.
Since there is (possibly) radical deflation, you might be tempted to just hold all your money and buy nothing. Pick vegetables from your garden. But the high marginal utility of the new goods and services will get you to spend, especially since you know that plenitude will bring you, in relative terms, a lower marginal utility for marginal expenditures in the future.
You might even go crazy spending. If nothing else, buy new and improved vegetable seeds for your garden. That same example shows that spending is robust to you losing your job, even assuming no reemployment is possible. In this world, there are significant Pigou effects on wealth.
Fed policy has no problem mattering in this world. Other people of course will wish to use the new Fed-sprayed liquidity to invest. They might even invest in AI-related goods and services, not all of which will be controlled by “billionaires.”
Liquidity trap arguments, if they are to work at all, require a pretty miserable environment for investment and also consumption.
Note by the way, that liquidity traps were supposed to apply to currency only! If you try to apply the concept to money more generally, when most forms of holding money bear interest rates of return, the whole concept collapses.
So there is not an aggregate demand problem in this economy, even if the social situation feels volatile or uncomfortable. After that, Say’s Law holds. If AI produces a lot more stuff, income is generated from that and the economy keeps going, whether or not the resulting distribution pleases your sense of morality. Along the way, prices adjust as need be. If unemployment rises significantly, prices fall too, all the more. I am not saying everyone ends up happy here, but you cannot have a) a flood of goods and services, b) billions accruing to the AI owners, without also c) prices are at a level where most people can afford to buy a whole bunch of things. Otherwise, where do you think all the AI revenue is coming from? The new output has to go somewhere, and sorry people it is simply not all trapped in currency hoards. Be just a little Walrasian here, please. (I would call it Huttian instead.)
Besides, why assume that “the machines” here are reaping all the surplus? Are they the scarce factor of production? Maybe it is hard to say in advance, but do not take any particular assumptions for granted here, ask to see them spelt out. One simple scenario is that the regions with energy and data centres become much wealthier, and people need to move to those areas. Maybe they do not do this quickly enough, a’la our earlier history with the Rust Belt. That is a problem worth worrying about, but it is nothing like the recent collapse concerns that have been circulating.
The whole Citrini scenario is incorrect right off the bat. Very little of it is based on sound macroeconomic reasoning. See Eli’s very good comments too. Nicholas also. Dare I say they should have consulted with the AIs for a bit longer?
The Software Upgrade in Chinese Civic Behaviour
I have not been to China recently enough to judge these claims:
Behaviour is notoriously harder to engineer than buildings. A recent trip to the Fragrant Hills in western Beijing on a newly constructed metro line, had me marveling at the improved crowd-management. Despite massive groups of domestic tourists from around the country thronging the area, in what would not-so-long-ago have been a scenario for a potential stampede, the crowds moved in relative order. The park environs were spick and span with no litter in sight; not a single old codger sneaking a cigarette.
There was some amount of strident rule-announcing on loudspeakers: stay on the designated tracks, no smoking etc., but overall, it was possible to enjoy the natural beauty, notwithstanding the hordes of day-trippers. The toilets were not fragrant, despite the nomenclature of the spot itself, but they were clean, and the seats were free of the tell-tale footprints that indicate squatting rather than sitting. Barely anyone gave me, an obvious foreigner, a second glance. In contrast, there was a time in 2002 when a cyclist fell off his bike in his shock at having spotted dark-skinned me walking along a road in the outskirts of Beijing.
So how had the Chinese been pacified/disciplined/habituated to ways of behaviour that went so against their until-very-recent, loophole-finding, chaos-shuffling, phlegm-expectorating deportment in public spaces?
The answer, as answers to sociological questions invariably are, is multipronged.
Some of it is more money.
