RT @andrewmgerard: @johnvanreenen's Economics of Ideas, Science, and Innovation lecture helps us think about how policy designs influence things we care about in science: research conducted, people trained, intellectual property protected (or shared with the public). The "lightbulb" table from John's paper with @heidilwilliams_ & @I_Am_NickBloom provides a quick way to think about the quality of evidence for different innovation policies and their net benefit. Find John's lecture here (with intro text from @matthewesche):

Example of a ‘Lost Marie Curie’? She Popularized Economics. Then She Was Erased From History. Why?

RT @sndurlauf: 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.

People finally accepting that UK showing productivity improvement - me in @FT @poid_lse Underlying research Our policies of stable fiscal framework, investment boost, planning reform helping

RT @antoniomele101: 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. UK finally showing signs of productivity boost, say economists via @financialtimes

New @ONS numbers confirms that UK productivity growth recovery continues (need to use reliable admin RTI data not LFS): Consistent with our findings on data through 2026Q1 @poid_lse Details:
