Econ perspective: People make choices to satisfy their preferences. Psych perspective: People adapt their preferences to justify their choices. Here's a theory that combines them. (A new working paper joint with Erik Eyster and Sarah Ridout.) arxiv.org/abs/2107.07491🧵

In 1750 Portugal had an output per head higher than France or Spain. One century later it was Western Europe's poorest country. Why? Find all about it in this new working paper, joint work with the extraordinary @dkedrosky (watch this kid, he's going far):

Fascinating new paper in AER: Insights shows that adoptive moms experience a similar earnings penalty as biological moms. Suggests biological factors such as child birth and breastfeeding are less important for earnings penalty than factors related to culture/preferences/norms.

Can we measure platform bias in the music industry? We test for bias in playlist rankings at Spotify and provide an empirical approach that is applicable in other platform contexts. The paper is now forthcoming at IJIO: sciencedirect.com/science/articl… Check out this🧵for more!⤵️

Powerful platforms – and the possibility of bias - are on everyone’s mind these days. For example, Google got in hot water for favoring its own properties in search. How about bias at Spotify? 1/n https://t.co/UjDJoZpBNp

George Constantinides: people face costly idiosyncratic shocks. Huge value to covering these, which can be done more feasibly through insurance than for aggregate shocks (ie, income pooling ) ht @anup_malani and @MargRev nber.org/papers/w29009

It would be nice if startup employees could pool their earnings with 10-20 comparable startup peers. Odds of joining a Unicorn is low, so idiosyncratic labor risk is massive. But some diversification would bring nice smoothing just like VCs get.

Almost 5yrs ago, @Ogoun and I joined the Fed Board. Our offices were next to each other. We chatted a lot and started a project on banking competition (soon also joined by Mark Carlson). Now the resulting paper has been accepted at the JPE! Here is what we learned! 1/N

Oxford Economic Papers have just published "An Economical Business-Cycle Model" (w/ E. Saez). doi.org/10.1093/oep/gp… (ungated: pascalmichaillat.org/7.html) The paper builds a new business-cycle model centered on unemployment & tailored to the analysis of monetary & fiscal policy.

Whoever at the @nberpubs made the decision to keep the recordings of the Summer Institute livestreamed sessions open for everyone at youtube.com/c/NBERvideos, thank you! This is the right step towards transparency and accomodation of (junior) researchers from different time zones.

Many economics journals limit abstracts to 100 words. Working paper abstracts often >> 100 words. Which is true? 1. Journal abstracts too short given journal's interests. 2. Working paper abstracts too long given author's interests. 3. Misaligned incentives.

@ShengwuLi both 1 and 2 are true imo for the typical econ paper. 100 words is too short, 200 (my estimate of the typical WP abstract) is too long.
