I’m not sure what one could possibly learn from what amounts to a messy interrupted time series lacking a clear counterfactual. Wouldn’t be surprised if you found something similar among other (“comparable”) cities that didn’t experience this sort of deployment.

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.

Nonetheless, I decided to leave in search of more freedom in terms of both style and content. And that’s all I’m going to say for now. My “so long and thanks for all the fish” column will appear next week. As for future plans, watch this space 2/

My #EconJMP examines how how manufacturing firms respond to flooding. Do flooded firms build back better? Or do they suffer unrecoverable losses that weaken aggregate productivity?
