Should LLMs be used to review papers? AAAI is piloting LLM-generated reviews this year. I wrote a blog post arguing that using LLMs as reviewers can have bad downstream consequences for science by centralizing judgments about what constitutes good research.

These two papers, taken together, really cause a rethinking of behavioral economies.
Rather than having anomalous risk preferences; it looks like people have complexity aversion to "hard" decisions, especially on valuation, which drives behavioral anomalies. Herbert Simon ftw.

Occasionally, it still blows my mind how good the ChatGPT + R combination is for pulling data and producing graphs.
I used the package scholar to get citations data from Google Scholar to compare citation patterns for researchers across different cohorts.

Incredibly useful resource for all job market candidates! The timeline and the post-offer stage are quite different for econ/finance market, but nearly all the rest of the advice applies, including some advice you didn't know you needed (e.g., sample emails).
I wrote a Part IV postscript to my job market blog post to add what I've learned as faculty.
TL;DR: No one is out to get you. For anything not going your way, it's probably due to people being busy or bureaucracy. And there are probably people working very hard for you behind the scenes regardless.

A helpful mnemonic that I learned in school, but is apparently not commonly appreciated. How do you remember which functions are convex vs. which are concave (and in doing so, which direction Jensen's inequality goes)? Concave functions look like caves.

If you're on the market as an IO or IO-adjacent economist, I really encourage you to sign up.
I've heard of people using this list for many things, both during the market (e.g. recruiting) and after (e.g. inviting for seminars). It's an easy way to get some exposure.
