As I told the NYT, the recent deployment of the National Guard to select Democratic cities has been criticized for many incredibly valid reasons—including the fact that they are not a substitute for municipal police.
The New York Times@nytimes.com · 11mo agoSome mayors and police chiefs around the U.S. said they would welcome more traditional law enforcement cooperation with federal agents, but see deploying the National Guard as a step too far. “We do not want an occupation, and we also want something that is sustainable.”

How do firms respond when faced with climate shocks? Tarikua Erda's research examines how firms adjust physical capital investment and entry/exit decisions, providing key evidence to a long-standing puzzle. (Among other interesting projects: www.tarikuaerda.com)

Thanksgiving this year falls on the 28th, and 28 is a perfect number – meaning that it is equal to the sum of its proper divisors (28 = 1 + 2 + 4 + 7 + 14). So... I hope you have a truly perfect #Thanksgiving!!

2. Researchers *do* make many specification choices in the current environment. For example, functional form of the outcome (log vs. level?), set of controls (how many FE?), and the set of UNITS to include. We need to have a more balanced look at this trade-off.
