This is an interesting set of academic research papers about the increasingly key debate of when AI should be used to label data (an expensive task we use humans for)
Yang et al show that AI answers are quite different than human, but Briggs finds it may be because AI is better than human RAs!

Attention IO job market candidates:
Sometimes speakers in the CMA's external economics seminar series have to cancel at relatively short notice. We would love for these slots to go to JMCs to present their job market paper.
Drop me a message if you are interested or share with those who might be.

This paper shows that you can predict actual purchase intent (90% accuracy) by asking an off-the-shelf LLM to impersonate a customer with a demographic profile, giving it a product image & having it give its impressions, which another AI rates.
No fine-tuning or training & beats classic ML methods.

On one hand: don't anthropomorphize AI. On the other: LLMs exhibit signs of gambling addiction.
The more autonomy they were given, the more risks the LLMs took. They exhibit gambler's fallacy, loss-chasing, illusion of control...
A cautionary note for using LLMs for investing without guardrails.

Together with Tai Lam, Nicolas Padilla, and Anja Lambrecht: we study the impact of LLMs on user behavior across the web. We use a large and detailed panel of user-level online browsing from 2022 – 2023 and study how consumers' behavior changes after they adopt AI tools.

The GOAT
A huge moment -- Melvyn Bragg steps down from In Our Time after over a quarter of a century. What a programme and what a legacy! Just a model for how to make great, clever, engaging radio, and a twenty-seven-year experiment that proves there's a huge global audience for smart, scholarly programming.
