Forthcoming in AEJ: Microeconomics: "Estimating Models of Supply and Demand: Instruments and Covariance Restrictions" by Alexander MacKay and Nathan H. Miller. aeaweb.org/articles?id=10…

If you want to try out this approach in your own BLP estimation, PyBLP has pretty good support! Thanks to Alex MacKay for helping with getting it added. Adding covariance restrictions was fairly straightforward, with one sort of obscure technical challenge. 1/6

Excited to be part of the session on concentration and markups at #SED24 with Monica Morlacco and Vladimir Asriyan! Join us tomorrow at 15:30 to hear about our new paper with Alberto Cavallo, Alex MacKay, and Santiago Alvarez Blaser on markups and pricing behaviors along the supply chain.

As inflation surged post-pandemic, the prices of the cheapest products grew 1.3 to 1.9 times faster than those of premium products. We coined the term "cheapflation" to highlight this disparity, which is present in many countries, including the US (shown below) Our results

Cheapflation—a faster rise in the prices of cheaper goods relative to the prices of more expensive varieties—is a global phenomenon that occurs during an inflation surge. This table from our paper shows the cumulative inflation rates from 2020-24. In relative terms, Germany and

New markups paper alert! 👇👇👇👇 How do markups vary over time along the supply chain? To address this question, I'm very excited to share a new working paper from the HBS Pricing Lab, joint with Santiago Alvarez Blaser, Alex MacKay, and Paolo Mengano: papers.ssrn.com/sol3/papers.cf…

Check out our new paper! 👇

Exciting excellent granular data on markups shows: markups did NOT rise during the surge in inflation. No greedflation. This is the data where this can be tested, NOT a decomposition of GDP deflators. PS: I followed this paper closely since co-authored by my grad student, it …

La Greedflation è una narrazione di successo, ma è falsa. Uno studio di Alberto Cavallo, Paolo Mengano et al. Sui markup mostra che non c’è stata “inflazione da profitti”. Conclusioni analoghe a uno studio di Banca d'Italia (Eliana Viviano et al.). ilfoglio.it/economia/2024/…

Always great to talk to Tim Graf for this podcast. I talk about the markups and greedflation results of our new working paper with Santiago Alvarez Blaser, Alex MacKay , and Paolo Mengano, and then share some of my inflation views in the US and Japan.

I created an AI podcast of my latest markups paper using Google's NotebookLM and the results are truly impressive. As one of my coauthors put it, the AI hosts have clearly never bought a car, but still...
