An important paper by Agnes Norris Keiller, Aureo de Palma @PaulaAureo, and John Van Reenen @johnvanreenen. The use of firm beliefs about future inputs and outputs represents a new route to identification under weaker assumptions than have been required in previous research. The excellent associated thread gives details.

Labour share continues to fall in US https://t.co/V0viENlKMU Goes alongside rise of superstar firms https://t.co/j6NcUTRgDP This is not happening everywhere, though: in UK productivity & wages continue to move together https://t.co/e0whv1N587

[John Van Reenen @johnvanreenen]

This is strong planning reform from Labour government to give default ‘yes’ to housing around commuter rail stations. Builds on our planning reforms in Dec 2024 that OBR scored to raise GDP by >£100bn.

At least partially AI-driven, says my colleague @johnvanreenen .

And @andrewishart (who used to be my student ages ago) suggest that it's tech-driven.

We are so back.
