I set up a new website to host my working papers, notes, and teaching material. E.g., here are my notes on postgrad macroeconomics:

Please feel free to use and share — but do be on the lookout for typos! I’ll have to do a major typo fix at some point…

Our paper on the availability of wage information in job postings is now in Labour Economics. Data is high quality and tells an important story: employers really don't tend to include wages in their ads. Important facts for thinking through how labor markets work.
Absolutely ridiculous.
Even writing text manually and asking the AI to edit will result in a false positive.
Imagine if using spellcheckers in MS Word triggered a “mostly AI” alert

Recently, I received a review of a text of mine (which I wrote based on a text written by myself) saying it was 21% human. Of course I never thought to verify it was not AI as I did the job.
As a non-native English speaker I must check my grammar and spelling mistakes. Is that process enough to move a 100% human written text to a 21% when you had at most 5 corrected mistakes?
Turns out I submitted myself the original text and it said 85% human… so I went from a bias of 15pp to 79pp after my checks.
This verification process only benefits native speakers who can confidently trust their own words. A huge disadvantage for people coming from a non-English speaking background.

Review of Economic Studies is happy to announce the launch of the new journal, Review of Economic Studies: Insights. This is an open-access, general-interest economics journal that will publish short papers with a fast review process and accept/reject decisions.

The silver lining of AI in econ research: replications and accuracy should significantly improve.
The amount of articles that were published in the 2000s — coinciding with big advancements in computational power but janky software/code — I’ve tried but failed to replicate…

The "China shock" narrative illustrates why the lack of debate is a problem in economics.
Autor et al. published a series of articles that have since been falsified by subsequent research. However, few realize this, which means the articles persist, like zombies. 1/8

🚨 New Paper Draft🚨 How do families share income risk across borders? We use 150m+ transactions from a global money transfer operator (MTO) to study remittances at high frequency, and build an open-economy HANK model with cross-border families. Joint with @adisoenarjo 1/10
Can walk and chew gum. Pure AI reviews and vendor lock-in for refine are both major issues.
Totally share your concerns. You’re also highlighting a problem that goes back before LLMs — reviewers outsourcing their duties to grad students for example.
You're trying a motte-and-bailey fallacy. Not interested in engaging with that. Go back and reread my posts on the matter.
This is a bit disingenuous.
The negative reactions are mostly centred on the adoption of proprietary and expensive software.
Almost no one is rejecting the adoption of AI.
The backlash to this announcement would be, I bet, negligible if instead of “refine” it was just “frontier LLM models”.
The main point of contention is the vendor lock in of proprietary and expensive software, potential moral hazard, and slippery slope problem.
Hire more editors. Better yet: let editors use whatever AI assistant(s) they want. There is very little reason for them to be adopting a proprietary — and expensive — solution for this problem.
No vendor lock ins!
I have very mixed feelings about this.
If not handled correctly, this will be a disaster to the field.

@CJenGo88 & Silvana Tenreyro 🚨
Recent technological breakthroughs raise an important question for policymakers: will higher
productivity be inflationary or disinflationary?
