The disinflation of the early 1980s achieved by Paul Volcker has served as the exemplum of the power of hawkish monetary policy. Our analysis reveals that current inflation, especially core inflation, is considerably closer to previous peaks than in the official series.
^Jeanna Smialek summarizes the paper in the NYT/another thread
The interesting fact is that commercial property transactions disproportionately happen between buyers and sellers of the *same nationality*, regardless of where they occur. These insights are from a comprehensive international dataset tracking all large transactions. 2/9

Cosman and @leqonomics find that concentration among housing developers has increased substantially since GFC; from bankruptcy by developers, regulatory shifts, and mergers.

Interesting discussions
I'm collecting mean referee comments to make a point. Please tell me the meanest one(s) you have gotten.
You can reply to this thread or DM me or fill out this Google form: forms.gle/qjY7DXdTzKPVH5…
I may re-post the comments publicly, so be sure you're ok with that.
"Data available upon request" doesn't work. In case you didn't already know that, there's a new study of Biomed Central papers. 1792 manuscripts indicated authors are willing to share their data. 93% either did not respond or declined to share their data.
- The data is available upon request (but not really).
- Little is known about this topic (at least for the first 3 pages of Google Scholar)
- This is a topic for future research (that we already have a working paper on)
"<-" instead of "=" in R is one of those things people do that they literally do not need to (and should not) be doing, since R supports the latter.
