With unique data from a large global manufacturer, we were able to study how product markups vary along the supply chain and over time.
One thing that surprised us: though manufacturer and retail markups bounce up and down, total (manufacturer + retail) markups are stable.

#rstats #econsky PSA: The next release of `fixest` will include some important changes (plus cool new features).
E.g. Fixed-effects regs will now default to 'iid' SEs rather than clustered. github.com/lrberge/fixe...
You can install and test drive the dev version from R-universe; see the README.
