AI and scientific literature reviews
Tyler Cowen
Introducing PaperQA2, the first AI agent that conducts entire scientific literature reviews on its own. PaperQA2 is also the first agent to beat PhD and Postdoc-level biology researchers on multiple literature research tasks, as measured both by accuracy on objective benchmarks and assessments by human experts. We are publishing a paper and open-sourcing the code. This is the first example of AI agents exceeding human performance on a major portion of scientific research, and will be a game-changer for the way humans interact with the scientific literature.That is from Sam Rodriques, with further links. I have not had a chance to try this out.The post AI and scientific literature reviews appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesAI prediction marketsHow weird will AI culture get?Cosmos Institute

How much of the recent inflation was caused by deficits?
Tyler Cowen
This paper measures the causal effect of deficits on inflation using a “high frequency narrative approach”. We identify an event that released news about the 2021 deficits in the United States—the Georgia Senate election runoff. We calculate the size of the shock using new narrative data from investment banks. We then study the high frequency response of inflation forecasts from asset prices, in order to separate deficits from other factors affecting inflation. We estimate an “inflation multiplier” of 0.18% price level growth over two years, for a 1% deficit-to-GDP shock. Our estimate implies that the 2021 deficits caused around 30% of the 2021-22 inflation—meaning deficits were important but not the only cause. A standard heterogeneous agent New Keynesian model quantitatively matches the size and dynamics inflation multiplier.That is from a new paper by Jonathon Hazell and Stepan Hobler.The post How much of the recent inflation was caused by deficits? appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesShould we keep the wealthy non-diversified?

Which U.S. Stocks Generated the Highest Long-Term Returns?
Tyler Cowen
This report describes compound return outcomes for the 29,078 publicly-listed common stocks contained in the CRSP database from December 1925 to December 2023. The majority (51.6%) of these stocks had negative cumulative returns. However, the investment performance of some stocks was remarkable. Seventeen stocks delivered cumulative returns greater than five million percent (or $50,000 per dollar initially invested), with the highest cumulative return of 265 million percent (or $2.65 million per dollar initially invested) accruing to long-term investors in Altria Group. Annualized compound returns to these top performers relatively were modest, averaging 13.47% across the top seventeen stocks, thereby affirming the importance of “time in the market.” The highest annualized compound return for any stock with at least 20 years of return data was 33.38%, earned by Nvidia shareholders.Here is the full paper by Hendrik Bessembinder.The post Which U.S. Stocks Generated the Highest Long-Term Returns? appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesHow much of the recent inflation was caused by deficits?Should we keep the wealthy non-diversified?

Equality Act 2010
Alex Tabarrok
The UK’s Orwellian sounding Equality Act 2010 is strikingly Marxist. It demands equal pay for work of equal value where these are defined as follows:A’s work is equal to that of B if it is like B’s work, rated as equivalent to B’s work, or of equal value to B’s work.A’s work is like B’s work if A’s work and B’s work are the same or broadly similar, and such differences as there are between their work are not of practical importance in relation to the terms of their work.…A’s work is rated as equivalent to B’s work if a job evaluation study— gives an equal value to A’s job and B’s job in terms of the demands made on a worker…A’s work is of equal value to B’s work if it is neither like B’s work nor rated as equivalent to B’s work, but nevertheless equal to B’s work in terms of the demands made on A by reference to factors such as effort, skill and decision-making.In short, supply and demand have been replaced by judges and labor boards with the authority to deem which jobs are “equal” and therefore should be paid equally. And the labor boards do so based on vague and subjective considerations that do not change with changing circumstances. Imagine replacing “jobs” with “condiments” and having judges decide whether ketchup and mustard should be priced equally because they are similar, broadly comparable, or rated equivalent in terms of the effort, skill, and decision-making that went into their production.You think I am joking. I am not. Here’s an example of a case just decided in the UK.More than 3,500 current and former workers at Next have won the final stage of a six-year legal battle for equal pay.An employment tribunal said store staff, who are predominantly women, should not have been paid at lower rates than employees in warehouses, where just over half the staff are male.The tribunal ruled that retail workers and warehouse workers were “equal” and thus had to be paid equally. Next replied that they paid everyone market wages. Verboten!Next argued that pay rates for warehouse workers were higher than for retail workers in the wider labour market, justifying the different rates at the company.But the employment tribunal rejected that argument as a justification for the pay difference.According to the tribunal’s ruling, between 2012 and 2023, 77.5% of Next’s retail consultants were female, while 52.75% of warehouse operators were male.The tribunal accepted that the difference in pay rates between the jobs was not down to “direct discrimination”, including the “conscious or subconscious influence of gender” on pay decisions, but was caused by efforts to “reduce cost and enhance profit”.It ruled that the “business need was not sufficiently great as to overcome the discriminatory effect of lower basic pay”.No one is alleging that male and female warehouse workers were paid unequally or that male and female retail workers were paid unequally or that there was any direct or indirect discrimination. The only claim is that warehouse workers, who are less likely to be female than retail workers, earn more than retail workers. And since these jobs have been judged “equal,” the company has violated Equality Act 2010.Who could have predicted that such different jobs would be deemed equal? Yet because Next failed to foresee that warehouse and retail jobs might one day be deemed “equal,” they are now required to pay millions in back wages to their retail employees. Software engineers, particularly in AI, are currently in high demand. A British firm looking to hire them may hesitate to raise wages, fearing that a future ruling could classify software engineers as “equal” to a larger, lower-paid group like HR administrators. Such a decision could easily push the firm into bankruptcy.The warehouse workers were almost 50% female (47.25%). So females were not barred from the higher paying jobs. The fact that 77.5% of the retail workers were female suggests that retail work has special appeal to females relative to males and thus that there are compensating…

Deep Prasad writes:OpenAI just released an AI as smart as most PhDs in physics, mathematics and the life sciences. Wake up. The world will never be the same and in many ways, it will be unrecognizable a decade from now.Mckay Wrigley is enthusiastic:o1’s ability to think, plan, and execute is off the charts.Ethan Mollick says:There are a lot of milestones that AI passed today. Gold medal at the Math Olympiad among them.Like Ethan, however, I agree the model is not necessarily better at a lot of non-reasoning tasks. Ethan also notes that AGI will be jagged and uneven.Subbarao makes guesses as to how it works. Here is some other guy saying a bunch of stuff. And yet further commentary.Whatever you think of those specific claims, there is a lot of room, as with the John Lennon “Strawberry Fields Forever” demo, to get a lot better yet. For one thing, it can think for longer yet! Whole new doors have been opened, and if you are reading some lukewarm commentary that is probably what the person does not grasp. It is the people who think “…if they can do this…” who have been most successful in predicting the course of AI.Shital Shah remarks:This is truly a game changer and step change. It takes us out of slow progress constrained by compute capital and training tokens to rather open world where time is the only limit.I would love to have one of these (with some tweaks) as my agent.Taelin claims AGI is achieved.

“four percent of humanity subscribes to OnlyFans” (from my email)
Tyler Cowen
Andrew Cedotal writes me:This issue came up with the post where someone claimed that N% of Americans were active OnlyFans content creators, here it is again!For software services, total accounts ever created is a vanity metric. It’s not used by serious operators or investors of consumer-tech companies (the fact that it shows up in public financial reports so often thus has interesting implications).The social impact/business value of a software service is about flow (e.g. monthly active users and monthly revenue), not stock. 100 real human signups means many, many fewer actual monthly active users (MAU) at any point, because users churn out. Even the best-retaining services around (e.g. Snap) only have 90% yearly retention, which then compounds downward.Then there’s the issue that for any public software service, many accounts are bots, throwaways, people who forgot their password, etc.Rather than make a truly wild guesstimate, let’s look at a frontier based on the report of $6.6B gross payments made by users in 2023 (so average revenue / month is $0.55B). All of the following are possible points on the frontier of paying MAU (paying monthly active users) vs. monthtly APPPU (monthly payments per paying user):* 10 million paying MAU, $55 monthly APPPU
* 30 million paying MAU, $18.33 monthly APPPU
* 50 million paying MAU, $11 monthly APPPU
* 100 million paying MAU, $5.5 monthly APPPU(Industry standard is to look at ARPPU–average revenue per paying user–and not average payments, but I think here we’re more interested in determining how much money users are putting into it and ignoring platform take rate, not a financial analysis of the company.)Now, OnlyFans might have ~300M total signups ever, but let’s assume half of those are dupes and bots. So 150M real human signups. It’s unlikely that more than 20% of people who have ever created an account have ever entered a credit card, so that’s 300 * 0.5 * .2 = 30M as a cap on people who have ever paid. Take into account userbase churn, and a guess is ~12M monthly paying accounts right now (0.15% of humanity, not 4%), which would put them at $45.83 monthly APPPU or a yearly APPPU of ~$550.

* 100 million paying MAU, $5.5 monthly APPPU(Industry standard is to look at ARPPU–average revenue per paying user–and not average payments, but I think here we’re more interested in determining how much money users are putting into it and ignoring platform take rate, not a financial analysis of the company.)Now, OnlyFans might have ~300M total signups ever, but let’s assume half of those are dupes and bots. So 150M real human signups. It’s unlikely that more than 20% of people who have ever created an account have ever entered a credit card, so that’s 300 * 0.5 * .2 = 30M as a cap on people who have ever paid. Take into account userbase churn, and a guess is ~12M monthly paying accounts right now (0.15% of humanity, not 4%), which would put them at $45.83 monthly APPPU or a yearly APPPU of ~$550.

The economics of ride-sharing
Tyler Cowen
This paper examines the impact of the emergence of the “gig economy” on the broader labor market by exploiting the staggered introduction of the ridesharing service Uber to American Cities between 2013 and 2018. Using difference-in-differences methods, Callaway and Sant’Anna’s doubly robust difference-in-differences estimator, Chaisemartin and D’Haultoeuille’s time-corrected Wald estimator, and Abadie et al’s synthetic control method, I estimate that Uber’s arrival to a city resulted in decline in the unemployment rate by between a fifth and a half of a percentage point. This suggests that Uber allowed many workers to supplement their earnings during periods of unemployment, framing the ridesharing service as a complement to, rather than a substitute for, traditional employment. I also find some evidence that Uber had a very small positive effect on wages at the lower end of the wage distribution, suggesting that Uber may have altered worker search behavior or affected bargaining power.Here is the full paper from Tucker Omberg, via Stefan Schubert.The post The economics of ride-sharing appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesEquality Act 2010Which U.S. Stocks Generated the Highest Long-Term Returns?How much of the recent inflation was caused by deficits?

Civil War
Alex Tabarrok
MediaI knew Civil War (now streaming on HBO/Max) was going to be good when just a minute or so in you see an explosion in the distance and only later do you hear the sound wave. [Mild spoilers may follow.] Shortly after, we meet war journalist Lee (Kirsten Dunst in a standout performance). I thought, “She looks like Lee Miller,” and seconds later, the name is dropped. In the next shot, Lee is in a bathtub—a clear sign you’re in the hands of a master. It is not without import that Lee Miller photographed Dachua or a little less obviously that she was a pioneer of the surreal. Both will reappear in Civil War.In a scene where the journalists need to buy gas, they offer $300. The armed attendant scoffs, “$300 will get you a ham sandwich.” “$300 Canadian,” comes the reply, telling you everything you need to know about the state of the economy.Civil War was written and directed by Alex Garland, who also made Annihilation, Ex Machina, and the underrated Dredd (the 2012 reboot not the Stallone movie). Many viewers expected Civil War to serve some lectures about red state/blue state politics, but it doesn’t. Tyler makes astute comments about the hidden politics (and reviews the movie here).My interest was more on how the film captures the dual nature of war—war is hell but it’s also fucking amazing. The photojournalists at the heart of the story justify their actions as serving a higher purpose, but in reality, they have become addicted to the adrenaline. Civil War shares themes with Nightcrawler. The journalists also share more than they think with the sick fucks who also love war because it gives them a chance to torture and kill.A great scene at the climax incarnates the “when one dies, another is born” trope. The lead character starts to feel and gain a moral code, only to be killed for it, while the apprentice simultaneously sheds hers, emerging as a new, amoral hero. And it’s all caught on film. Karma is a bitch. The transition isn’t surprising given the logic of the setup but it is handled with originality and grace.Recommended, given the obvious strictures about violence and serious themes.The post Civil War appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media Media CommentsThis is hilarious.

What is Haitian food like in the United States?
Tyler Cowen
As late as the 1990s, food in Haiti probably was the best in the Caribbean, and it certainly was regarded as such. There were fancy French-Caribbean fusion restaurants in Petitionville with amazing seafood, and there was high quality street and diner-level food in Port-au-Prince. Lambi (conch) was consistently the best I ever have had, and the dish with rice cooked in the juice of those special mushrooms was outstanding — Djon Djon they call it. A simple breakfast with eggs and “combi hash” could be memorable. Griot (with sour oranges) was another option, and once I had the best (small) turkey I ate in my life, “dinde,” as it was called from the French. The food was indeed a reason to visit Haiti, at least if you had outside dollars to spend.As for poorer Haitians, and there are many of them, eating dirt cookies [bonbon tè], mixed with a bit of fat and salt, is indeed a thing.Haitian food in the United States can be decent, but it is far inferior. The conch is never truly fresh. The servings are far too carbohydrate heavy, with lots of plantains and rice. The stews can be decent, but there isn’t much variety of flavors. It is worth eating such Haitian food once or twice a year, partly for nostalgia value, but it is not really something I crave. I can recommend the sociology you observe in those restaurants, including their reactions to you.Maybe Brooklyn is best for Haitian food in this country? Some of the North Miami venues are skimpy on the infrastructure side, and not that many Haitians seem to live in Los Angeles. Maryland has a few decent places, and a few times I had tasty Haitian snacks served at late night Haitian concerts there. Possibly in Florida, but not in Little Haiti, would be another option, as I’ve had good Haitian food in both Tampa and Orlando.Addendum: The Chris Rufo bounty (supply is elastic!) did yield a video of some Africans barbecuing a cat, or is it rather a chicken?, but so far nothing of the Haitians.The post What is Haitian food like in the United States? appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media Media CommentsAfter the upset post about Vance’s couch-gate, it’s a bit ... by TriestAsk Alf. by Pubby🍺The Haitian cat video is coming as an October surprise! by RobPRelated StoriesTwo missing marketsFrance frozen croissant fact of the dayWhy do the servers always want to take our cutlery and plates and glasses away?

Are “anchor babies” underrated?
Tyler Cowen
Did you worry about the 2020 fall in U.S. fertility? Well, ponder this:Birth rates in Canada and the USA declined sharply in March 2020 and deviated from historical trends. This decline was absent in similarly developed European countries. We argue that the selective decline was driven by incoming individuals, who would have travelled from abroad and given birth in Canada and the USA, had there been no travel restrictions during the COVID-19 pandemic. Furthermore, by leveraging data from periods before and during the COVID-19 travel restrictions, we quantified the extent of births by incoming individuals. In an interrupted time series analysis, the expected number of such births in Canada was 970 per month (95% CI: 710-1,200), which is 3.2% of all births in the country. The corresponding estimate for the USA was 6,700 per month (95% CI: 3,400-10,000), which is 2.2% of all births. A secondary difference-in-differences analysis gave similar estimates at 2.8% and 3.4% for Canada and the USA, respectively. Our study reveals the extent of births by recent international arrivals, which hitherto has been unknown and infeasible to study.That is from a new paper by Amit N. Sawant and Mats J. Stensrud, via the excellent Kevin Lewis.The post Are “anchor babies” underrated? appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesEquality Act 2010Honduras and its disputesMental health trajectories in the UK
