Prediction markets paragraphs to ponder

by  Tyler Cowen

The oracle is an elaborate Web 3.0 contraption that combines cryptocurrency, voting and game theory in its goal to produce fair judgments. It’s billed by its creators, a company based in Manhattan called Risk Labs, as a “decentralized truth machine.”

But for all its brainiac complexity, the oracle has proved exploitable. Dozens of livid bettors claim the system has been gamed, the handiwork of a budding tech entrepreneur named Lancelot Chardonnet (his name at birth, he says). A look at the Donk debate, which unfolded over nine rancorous days, illustrates how he did it, and the messy, fractious challenge of divining something as nuanced as truth.

When the Bucharest video was first broadcast on April 11, nobody heard “Donk,” and this bet seemed destined to be won by those who bet “no.” Then someone noticed that the caster, who through sheer phonetic coincidence is known as Dinko, had botched “don’t.”

Dinko might have known about the Donk bet, so it’s at least possible that he said the fateful syllable on purpose. It’s even possible he placed money on the outcome. He might have made what linguistics fans would call a voiceless velar stop slip.

Jackson Dahl podcasts with me and Nabeel on aesthetics

by  Tyler Cowen in

Filmed at home, this ran about two hours, and yes that is Nabeel Qureshi, with a cameo from Spinoza toward the very end.  From Jackson:

From the episode summary:

Tyler and Nabeel are good friends, and given how prolific Tyler is, I decided to use Nabeel as an entry point and interview them together. We discuss sacred commitments, AI acceleration, mentorship, friendship, and more, but I focused the majority of the conversation on art and aesthetics. Tyler and Nabeel are unlikely aesthetes given their day jobs, but in fact take art deeply seriously. They have a shared love for and similar tastes in art, music, and film, in particular. We discuss strange and beautiful art, aesthetic stagnation, and a wide range of favorites: The Beatles, Mozart, Mondrian, Springsteen, Lana Del Rey, Kanye West, Cassavetes, The Sopranos, Apichatpong Weerasethakul, and more.

Excerpt:

Tyler: (18:31) I think I’m very mundane in many ways. When Marc Andreessen had that famous tweet about not being too introspective, I know he got slammed for that, but I sympathize with that in many ways. I have my work. I focus on it. I want to go see places I haven’t seen before. That really drives me. I feel pretty well motivated. I do think all kinds of deep thoughts, but to me those deep thoughts feel more superficial than my so-called superficial urges to go around doing things. And I’m fine with that.

…Jackson: (23:25) Do you experience art primarily by thinking or by feeling?

Tyler: (23:29) I don’t even know what those words mean. I experience it by looking at it. I don’t think I have very deep emotional responses. I think it’s pleasure and I feel I learn a lot from it. When I go out and look at other works of art or just the world, I see a lot more than people who don’t live with art. I don’t think I feel that much. I’ve never cried in front of a painting. When I read these accounts of someone seeing a Madonna and weeping, it makes no sense to me. It’s like people who do sports gambling. Why do you do that? There are positive-sum gambles for you. Here are a few.

There is much more of interest, self-recommending!

AI cheating on math econ at Brown

by  Tyler Cowen in

The temptation to use artificial intelligence (AI) to cheat is shaking up elite universities in the United States. Professor Roberto Serrano, who is the Harrison S. Kravis University Professor of Economics at Brown University, has detected a massive fraud in one of the classes he teaches, ECON 1170, an advanced undergraduate course in mathematical economics. He has conclusive evidence that at least 50 students cheated on the March midterm exam, making it the biggest known scandal at Brown and in the entire Ivy League, which brings together the East Coast’s eight most elite private universities, including Princeton, Harvard, Yale, Columbia, Cornell, Dartmouth College and University of Pennsylvania.

When he reported the case to high-ranking officials at Brown, he got a cold reaction. The response from the president, he said, was absolute silence. The dean did not comment either until Serrano took the case before the Academic Code Committee.

Politically Incorrect Paper of the Day: The US Racial Wealth Gap

by  Alex Tabarrok in

Writing in the QJE, Derenoncourt, Kim, Kuhn, & Schularick argue that today’s black-white wealth gap can be explained by differences in initial conditions from over a hundred and fifty years ago, i.e. slavery. But there is an important, and glaring objection: in the age of immigration (1850–1924) millions of whites immigrated to the United States with essentially no wealth and yet they caught up to the “heritage” whites quite quickly and indeed today are richer than heritage whites.

Brian Marein collects and carefully analyzes the data:

Persistent racial wealth inequality in the United States is often attributed to the intergenerational transmission of historical wealth disparities. However, inferring the determinants of long-run inequality from group-level data is complicated by the arrival of 30 million Europeans during the Age of Mass Migration (1850–1924), who are by construction included in average white wealth despite having no direct claim to the wealth accumulated by earlier Americans. This paper accounts for this compositional change in the white population by documenting wealth dynamics among European immigrants and their descendants. Cash-on-arrival data show that immigrants began with substantial wealth deficits relative to the native-born. Yet by the late twentieth century, these deficits had closed, as indicated by comparisons between the descendants of later-arriving Southern and Eastern Europeans and those of longer-established Northwestern Europeans. This pattern implies rapid intraracial wealth convergence, in contrast to the slower convergence observed across racial groups. A stylized model shows that these differences can be largely accounted for by income. These findings demonstrate that large wealth disparities do not mechanically persist when groups have access to comparable economic opportunities.

If initial conditions don’t explain the wealth gap then the most likely explanation is an income and/or savings gaps. I am reminded of an earlier politically incorrect paper of the year by Nathaniel Hilger and see also my review of his book The Parent Trap.

Will future biomedical advances be low marginal cost?

by  Tyler Cowen in

Most pharmaceuticals involve high upfront costs, to discover and test the drug, and very low marginal costs.  Another pill can be printed almost for free.

That cost structure favors health systems, such as that of Britain, that try to pay lower for services.  They can end up getting a relatively good deal from price discrimination.  After all, they can be served at low marginal cost, at least for those ttreatments.

Now imagine a biomedical future where many more treatments are based on the sequencing of your individual genome, and then the development of specific treatments personalized to you.  Obviously it will depend on developments, but very likely those remedies will have relatively high marginal costs.

In that setting the British approach to health care procurement and pricing will work less well.  It is the well-capitalized, “overspending” systems, such as the United States, that will have an easier time making the adjustment.

“The rising relative advantage of well-capitalized health care systems” is a neglected trend, because it makes a lot of earlier elite pronouncements about health care economics look a bit off.

Typewriters and fertility

by  Tyler Cowen in

Workplace technological changes were instrumental in creating new tasks for women over the last century. This paper studies the adoption of the typewriter into US workplaces. Exploiting exogenous variation in typist demand across sectors, I document that the typewriter increased women’s labor force participation, leading to lower rates of marriage and fertility. These developments stemmed from a transition of White women from households into office work and an indirect crowding-in effect drawing Black women into household services. Acting as a “meeting technology,” the typewriter reshaped social interactions, enabling White women to marry above their socioeconomic backgrounds and achieve upward mobility.

Renationalising British utilities

by  Tyler Cowen

There is talk of this with the pending change in PM, but I would not do it.  I am quite aware that a) not all of the privatisations went well, and b) American data indicate that state-owned utilities do not seem very economically different than, or less efficient than, privately-owned utilities.  Especially for water, where the natural monopoly elements are especially strong.

Nonetheless massive restructuring will be needed to make all of these companies, no matter who owns them, “AI companies.”  That will require capital raises and pay scales that will be difficult for the public sector to pull off.  So right now renationalisation would be a mistake.

Most generally, I would say the returns to resource mobility will be rising significantly.

Blackpool fact of the day, observations on northern England

by  Tyler Cowen in

Blackpool Central was the world’s busiest station in 1911.  It was the station with the most platforms to close in UK in the Beeching cuts of 1964.

That is from the recent fun book Lancashire: Exploring the Historic County that Made the Modern World, by Chris Moss.  And I enjoyed this paragraph:

I’ve never felt or fully understood the alleged tension between Lancashire and Yorkshire.  The latter’s residents have good reason to boast, as they do with gusto, even if the ‘God’s own count(r)y’ schtick is wearisome nonsense.  Yorkshire is the UK’s largest county.  It has three national parks, two national landscapes (the new name for AONBs) and some of the most dramatic stretches of thePennine range.  Like Lancashire, it reaches from the hills to the coast.  There are fundamental differences.  Lancashire is Irish and Atlantic.  East Yorkshire is European and North Sea-facing.  Yorkshire is Anglican and past tense.  Lancashire is Catholic and forward-looking.  Lancastrians go in sideways; Yorkshire men, at least, barge in frontally.

I consider this book to be properly subjective.
