Very happy to see this chapter, co-authored with @BondoHansen, available online. Will be of interest to anyone interested in how machine learning is transforming the cultures of financial modelling and bringing about a closer alignment with Big Tech. https://t.co/jUGDTB1FLr

AbstractThis chapter examines the use of machine learning (ML) in financial markets and argues that the adoption of ML into finance is bringing to light ne

There is no AI economy. It loses hundreds of billions of dollars and all gains are in speculative valuation. The only one making a profit is Nvidia, and it doesn’t make anything. It resells Taiwanese chips to companies that use them to lose money.
New newsletter: The US economy is splitting in two. There’s a rip-roaring AI economy. And there’s a lackluster consumer economy. - Macro: Last quarter, spending on AI outpaced the growth in consumer spending - Stocks: In the last two years, ~60% of equity returns have come from

I don't know how people manage without air conditioning in this weather. The idea that opening a few windows and turning a fan on is good enough is crazy. The people responsible for stopping aircon from being built into in new build housing in Britain really should be in jail.

Now out with New Political Economy: What's going on in the legal back-end of 'innovative' climate finance constructs? I provide some additional clues to why it's so hard to de-risk private climate finance by public means. Open access, too! https://t.co/seaP6l4sG8

I’m a consultant in private practice in London and I treat patients covered by private medical insurance every day. If you think it’s better in the UK, think again. I’ll share some stories I and my colleagues see every day. After reading these please DM me or share your own 🧵

I’m born and raised in Norway. I think it’s a beautiful country that I would love to live/build in but right now that’s not possible. Sadly Europe as a whole is falling behind due to innovation hostile policies/culture. If you all help calling it out it might improve eventually🙏

To riff on Rosa Brooks’ 2016 book: “How everything became finance and Treasury became everything”
We live in an interesting world where, as a result of policy-by-tax-credit, Treasury now administers: Our largest housing program (LIHTC) instead of HUD Our largest energy program (ITC/PTC) instead of DOE One of our largest antipoverty programs (EITC) instead of SSA

🚨 New paper out! Excited to share this, where I take a 'weaponized interdependence' view at explaining historical failure and recent success in global tax policy - and how that view can help fight climate change and inequality🧵👇 #OA @Global_Policy: https://t.co/FSry1V1A5L

(1/2) We need more attention to selection bias in qualitative research. A new study in a top sociology journal examines "how young people experience policing," but it draws only on interviews of youth in an organization devoted to abolishing the police, one that bombards...

Wild how AI is quickly replacing “the market” as the preferred deus ex machina that American elites invoke to provide a future solution to a wicked problem so that they don’t need to do the difficult work of thinking carefully and making hard tradeoffs in the present day
Former Google CEO Eric Schmidt says energy demand for AI is infinite and we are never going to meet our climate goals anyway, so we may as well bet on building AI to solve the problem

Is there a word for overcomplicating a task with needless abstractions, only to achieve poorly what could’ve been done simply? In finance, that’s like delta hedging a long call and a short put separately to mimic a straightforward long stock position.
The insane irony of this is that each one of these failed multiplications requires performing trillions of successful multiplications

One of the weirder LLM glitches I've encountered. I asked my article summariser app to summarise a PDF with no embedded full text (PDF was just images of pages). Text extraction failed silently, and so no article text was provided to GPT-4-mini. In response, it pretended to be a
I created a Python app with Claude's help that lets you drag and drop articles into your browser for quick summaries via the OpenAI API. I'm finding it helpful for quickly developing a high-level understanding of literature in unfamiliar fields. Saves time compared to repeatedly

In his 1973 book The Coming of Post-Industrial Society, Daniel Bell argued that the shift to an information economy would enable women to compete more effectively in the labor market, as jobs would increasingly require education and intellectual skills rather than physical

For instance, this is a fascinating paper from the Journal of Finance from 2019 that makes the case that the demise of the doctrine of coverture -- which required women to transfer their assets to their husband upon marriage -- played a role in spurring industrialization in the
