What a second quarter run! We legit have the best bench in the league and Mike Brown has mixed up the lineups beautifully during these playoffs.

Way to fight back in the second half! Stepped it up on defense and found better offense along the way. Contributions of all sorts up and down the roster.
On to Gane 2. Letβs go @nyknicks!

Weβre up 19, but coming back from the half it would be nice if the Knicks could find some answers for this zone (other than running back off of misses and makes). Too many guys shooting well for the ball to be stopping, and the offense slowing down, this much.

So proud to celebrate my father @metrics52 at his Festschrift -- a gathering of people and presentations in honor of his career and legacy. He has influenced so many: generations of Angrists and a rockstar student family tree. An impressive array of causal effects!

New! @MGehrsitz & @MWillJr examine the effects of education on health. Exploiting a raising of school age (ROSLA) reform, they find that education reduces hospitalizations. Health improvements are strongest for life-style related conditions and among men. journals.uchicago.edu/doi/epβ¦
