Our paper on the economy-wide effects of common ownership is now available on the RESTUD website. Happy but also a little sad to have closure on this project from which I learned so much! doi.org/10.1093/restud/rdaf0…

Today's reading. An unnamed colleague called this paper "dry", which is probably true. This one is like wine: dry, sure, but complex and pretty darn nuanced. A lot of good insights here about the consequences of functional form assumptions in logit-world!

When estimating demand, the price coefficient may be biased because firms adjust prices in response to demand shocks. In this (forthcoming) paper, @NateHMiller and I show how to resolve this source of endogeneity by invoking the supply side in standard empirical models.
