News on sdid_event: - SDiD, DiD and SC can all be computed via the method() option; - added placebo() option to estimate pre-trends; - the package is now on SSC, so check it out by running ssc install sdid_event, replace Many thanks to @DanielPailanir and Damian Clarke!

年齢制限ギリギリで賞をいただきました www2.econ.tohoku.ac.jp/~DSSR/hosoya20… そろそろ色々と若手枠から外れるの悲しい😧

One hard thing about seeing the Callaway and Sant’Anna DiD estimator becoming so popular is to see people using it in a context that is not warranted. Please read the paper and understand its building blocks! But I guess these are rich people's problems!

Sneak peak of some slides from a guest lecture in a colleague's grad class on economic modeling. I had a lot of fun with these -- might try to write it up at some point

New paper! TWFE for diff-in-diff is biased under staggered adoptions. One fix is to use more parameters--estimate a separate treatment effect for each cohort at each time. But treating each TE like a free parameter wastes our knowledge that nearby TEs in time are likely similar.

横からすいません.ガウス過程事前分布は対応するRKHSが無限次元ならその標本路は確率1でそのRKHSに"含まれない"です.なので,事前分布固定のガウス過程回帰で最適レートを出そうと思ったら,対応するRKHSより広い範囲のクラス(より粗い関数)を考える必要があります. jmlr.csail.mit.edu/papers/volume1…
