Large new dataset of Amazon product reviews, including full text and photos and product characteristics, with individual *reviews labeled as fake reviews*.
I believe this is the first publicly available data of this kind.

🚨 New working paper 🚨
Demand for LLMs: Descriptive Evidence on
Substitution, Market Expansion, and Multi-Homing
A key question for the business of AI is the extent to which LLMs are differentiated from each other. I use data from OpenRouter to take a first look.

Great point from @andreyfradkin.bsky.social: as a movement’s policies become more incoherent and harmful, the quality of “experts” who are willing to publicly defend it decreases precipitously.

In the latest episode of our podcast, Justified Posteriors, we discuss whether interest rates should rise in anticipation of AGI (as predicted by @basilhalperin.com). Our priors are quite different! Do check it out.

Can report that Deepseek writes perfectly serviceable referee reports of empirical papers submitted to Management Science. Note, I will still write my own, but you should update accordingly and ask it to provide feedback on your paper prior to submission.

It's the best time ever to experiment with new coding tools. Coding with o1-preview is very effective for hard research tasks (structural modeling with pyTorch, functions for custom latex tables, computing Hessians). 4o/Claude do well on simpler data cleaning with just a little guidance.
Just a reminder that @gmcd.bsky.social and @kylefbutts.bsky.social have made an incredible public good describing how to use data.table and fixest to encourage moving from Stata to R!

Recently read Boom, the new Stripe book about bubbles. It wasn't a great book, but it did give a lens into what areas of academia influence discourse in Silicon Valley. Research in innovation is influential, but research in macro and finance is not. Any theories for why?

This is a nice paper! Explains why home exchange networks can exist in equilibrium.

Popularity of token money is ⬆️ to allocate class seats, food donations, holiday homes, …
My #JMP asks
1️⃣Does price-setting with tokens work as in normal markets?
2️⃣Can token money have advantages even when using real money is possible?
Surprising answers: NO, YES!

Economics research hot take. We're entering a golden era of structural estimation. Gen AI tools make it so easy to translate models into code and to optimize computation that the formerly painful parts of structural aren't so bad anymore.

Small way in which AI is making me more productive. I asked Google's Bard:
"Find all of the uber and lyft receipts using gmail from my recent trips to chicago and toronto" and it successfully retrieved the correct emails. Very impressed.
