Alexei Navalny ist tot. Putin und sein Regime haben so oft versucht ihn umzubringen, einmal konnte er in Deutschland gerettet werden. Die Hoffnung auf ein anderes Russland darf nicht sterben.

Very much enjoyed yesterday’s Helmut Schmidt Lecture 2023 in Berlin held by Moritz @schularick.bsky.social (@kielinstitute.bsky.social) on Remaking Globalization. Would be interesting to see new streams of economic thought that further investigate the efficiency-security trade-off.

“In both its spatial and temporal aspects, global climatic change stands almost alone among the world's environmental problems” (Copper, 1978). Institutions haven’t yet adapted enough. Let’s see if #COP28 turns out to be “incremental” or “transformative.”

The first result is a descriptive fact: After marriage, female earnings drop by 20% (solid line, accounting for the child penalty). We combine admin and survey data from Germany here. But it’s not a German feature! We document a marriage gap for other European countries.

Urteil des BVerfG erschwert dauerhaft die Umgehung der Schuldenbremse. Die Bundesreg. könnte nun für 2023 oder 2024 erneut eine Notlage erklären, aber das könnte auch vom BVerG kassiert werden. Dann bleiben nur Ausgabenkürzungen oder höhere Steuern. Da stehen schwierige Verhandlungen an.
