One of the nice things of seeing former students develop is when they point you to read something you had no idea existed, making the (former) student, the teacher... Today @jeanjhoh told me about Schumpeter's "Imperialism and Social Class" cdn.mises.org/Imperialism …

I am increasingly convinced that, aside from data restrictions and computational constraints (as more papers rely on “universe” data), fully automated verification and routine robustness checks of empirical social science is achievable in the near future.🎆
1/🧵 A major update to our paper: "Scaling Reproducibility" w/ @YangYang_Leo.
We move beyond reanalyzing a single design to (almost) full-paper replication!

New preprint! We re-analyze 46 papers that use log-like specifications (ln(Z 1), inverse hyperbolic sine, etc). We find widespread non-robustness, and we show through theory simulation how these models drive spurious significance. 1/

The NBER recession dates from before 1927 are fundamentally different from the modern dates. They measure something different (movements is output relative to trend). So, are not comparable with the post-1927 dates.

1/ 🚨 New tariffs are here. What did we learn from the last round? Our research (AER: Insights 2021) shows that tariffs on imports largely hit US firms—not foreign exporters. But front-running, trade diversion, and lower margins meant the impact on consumer prices was limited in the short run. 🧵
