As with every dead child in Berlin traffic, the car-driving human who killed the child will get away with a slap on the wrist.
This driver was going 90 where he was supposed to go 30, over a bike lane and a bus lane to bypass traffic. Still, won't be enough.

From the Economist:
A huge majority (74%) of Ukrainians favour fighting on even without US support. A clear majority (59% v 21%) say they believe #Ukraine can still win on the battlefield, in contrast to American officials such as Marco Rubio, the US sec of state, who say it can't.

New data alert! 🎉
I published an article in the ifo Schnelldienst that introduces new monthly time series on producer prices and real industrial turnover for the 16 German states since 1991.
Hope to enhance regional business cycle research with these data.

One of my least favorite aspects of the dominant culture in our field is that if there is one good estimate of something (say the MPC) then it gets much harder to publish additional estimates (especially if they confirm earlier results). 1/4

#EconSky, what are your favourite examples of papers using micro-econometric methods to answer macro questions?
(I would like to include more such papers as examples in the first-year econometrics course of our PhD sequence.)
