Body-worn cameras reduce police use of force by 61.2%. Just Accepted new paper by Daniel AC Barbosa, Thiemo Fetzer, Caterina Soto-Vieira, and Pedro CL Souza zurl.co/aZFHH
Monitoring Technology: The Impact of Body-Worn Cameras on Citizen-Police Interactions
Abstract. We provide experimental evidence that using body-worn cameras (BWCs) for police monitoring improves police-citizen interactions. In an intervention carried out in Brazil in 2018, we find that treated incidents show a 61.2% decrease in police use of force and a 47.0% reduction in adverse interactions, including handcuff use and arrests. The use of body-worn cameras also significantly improves the quality of police reporting. The rate of incomplete reports dropped by 5.9%, which is accompanied by a 69.2% increase in reported incidents of domestic violence. We explore various mechanisms that explain why BWCs work and show that the results are consistent with the police changing their behavior in the presence of cameras. Overall, results show that the use of body-worn cameras de-escalates conflicts.

My JMP asks a classic question:
Do large, dominant firms foster or hinder innovation?
To study this, I turn to the Great Merger Wave (1895–1904), when >2,600 U.S. firms combined into corporate giants like U.S. Steel and DuPont.

If you think a credible economic impact projection model is feasible, then you have to do 3 things.
1) Develop such a model.
2) Demonstrate it projects accurately using past data.
3) Publish it in a peer-reviewed journal.
Otherwise, you're just wishcasting.

It's time to stop pretending that these are good-faith estimates that are exaggerating or being abused on the margin. Projecting the "fiscal impact" of a stadium over a 30-year lease is a fool's errand. If you disagree, show me one done right.

The SEA conference is my favorite on the calendar and these great NAASE sessions play a big role in that.
Many thanks to the presenters and attendees in NAASE's sessions at the recent Southern Econ. Assoc. conference in Tampa for interesting papers and insightful comments. We hope to see the attendees again soon and hope others will join us at upcoming conferences.
