Our hearts are heavy tonight.

Please join me in praying for the family of DPS Trooper Sergio Romero, who was killed in the line of duty today near Childress while serving and protecting his fellow Texans.

Trooper Romero leaves behind his wife, two young children, and countless friends and colleagues who are grieving this tremendous loss. As a member of DPS Recruit Class B-2025, he answered the call to serve and made the ultimate sacrifice in that service.

May God comfort his loved ones, his DPS family, and all who knew him. Rest in peace, Trooper Romero.

Hey #EconTwitter, I'm on the job market with a paper about open source software. OSS is a global public good, widely used and provided by the private sector, but the target of recent industrial policy.

Excited to teach this workshop!

It combines what I've learned from teaching demand estimation and Python to doctoral students, fielding PyBLP questions from users in academia/government/industry, and my own research with @conlon_chris.

@Spacehuskyx @florianederer Of course! Quick summary:
Markups are (roughly) how much retailers charge above cost. If a retailer buys a pack of Oreos for $1 and sells it for $1.25, that's a 25% markup.

There's a large body of evidence that markups (in retail and beyond) have been rising for several decades

Updated version of our "micro BLP" paper! My earlier thread (https://t.co/PePhgXavpo) summarizes some of the key points.
