📢I am happy to share my Job Market Paper!

My paper examines the relationship between policy intensity and policy effectiveness. I challenge the notion that more intensive policies are necessarily more effective—both theoretically and empirically—by showing that policy avoidance increases as the policy becomes more stringent during the early period of implementation.

Does social media content affect real-world violence?

In my #JMP, I show local aggressive tweets increase geographically distant but online connected regions crimes. I build a three-step causal chain. [1/6]

The virus does not care whether it's the workers at meatpacking plants or the prisoners or prison staff or folks who live or work at nursing homes who are "most affected" or "most at risk" from COVID.

It gets a foothold anywhere, it affects all of us:
