🚨New paper🚨

Classic rational inattention says people weigh costs vs. benefits when processing info.

We show that overprecision biases this evaluation — leading to misallocated attention.

Come and listen to me talk about my work on what consumers think about central bank inflation forecasts and how that affects inflation expectations and trust at the "Theories and Methods in Macroeconomics" Conference.

There are many other interesting projects too!

Thanks to everybody who chimed in!

I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist.

So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>

The "unexpected compression" in wages continues!

Non-managerial wages (for around 80% of private workforce) continues to grow somewhat stronger than overall wages. This means the reduction in wage inequality post-pandemic has remained, and continued (at a slower pace).

💡 TL;DR: We blend a behavioral bias into rational inattention — and find new welfare implications. Overprecision distorts attention, causing people to suboptimally underreact to information.

We find
✅ Feedback reduces overprecision
✅ Higher attention cost → less updating and more error.

But here’s the twist:
❗️Overprecision amplifies the effect of attention costs

This reflects irrational inattention: suboptimal updating due to biased beliefs, not just costs.
mvbulutay.bsky.social
We ran a pre-registered experiment to test the model.

🎯Task: Guess average age of people in historical pictures (e.g., Solvay Conference) — before & after seeing info.

Treatments:
- Feedback on belief calibration (overprecision shifter)
- Noise on the info (attention costs shifter)
mvbulutay.bsky.social
We extend rational inattention theory to incorporate overprecision.

A new prediction: Reducing costs of info processing has asymmetric welfare effects.

Example: A central bank simplifies communication to reduce inattention.

✅ Overprecise households react more
❌ Underprecise households react less

This is something people undervalue about laboratory experiments. One can credibly boost the understanding of instructions, sometimes just by reading them aloud.

(Study 2) They use lab participants instead of Prolific recruits. Study is pretty much identical to Oprea except for language and currency.

(Study 1) They run a variant, aimed at ensuring that subjects understand the task, in which "an experimenter ... read the instructions aloud."

I’ve just completed a revision of a paper titled “Psychological narratives in decision theory: what they are and what they are good for.”

I believe it makes a contribution to the recent literature on the epistemic role of narratives in science, particularly in economics.

This is a great opportunity to join us in the beautiful city of Heidelberg.

Let me note that experiments are a common method among the faculty, including macroeconomists and microeconomists.

That sounds like a good idea. I just hope it doesn't have unintended effects like discrimination.

I finally have a publication date for my new Experimental Economics textbook: December 12. Equally as important, I am proud to have negotiated a low price for the book: $38.10...for a nearly 800 page book!

Much of the recent literature uses non-incentivized measures of beliefs and attitudes. The typical justification is based on simplicity. This study seems to show otherwise.

If one person gives a euro to Ukraine, the result is €1.

If two people give 2 each, it is €4.

If 3,000 give 3,000 each, it is 9 million.

I wonder if they would behave differently if there were some humans in the market. The common knowledge of rationality may be what's driving their outcome.

This is a very interesting result.

My opinion: RCTs remain one of the more robust methods for p-hacking because the results are more verifiable due to data availability, pre-registration, and simplicity of analyses. In contrast, IV, structural, and simulations are much more flexible for p-hacking.
prashantgarg.bsky.social
There is large variation by Methods.

RCTs and RDDs have relatively high null results across all fields. Typically, with RCTs it is harder to do specification mining to get your desired large result.

Sadly, the scandal shows there may be other research malpractice that can get you there.
