The Missing Middle – How Market Design Gets Built for the Public Sector | with Thilo Klein
In this episode, we speak with Thilo Klein about daycare allocation in Germany – a problem that is still mostly run by uncoordinated offers, even though it is well understood in matching theory.

Talk is cheap – literally. But if words cost nothing, why do we ever trust them? In this episode, Yale Professor Navin Kartik breaks down the game theory of communication. We kick things off with the basics: what is the academic definition of "cheap talk", and why does cheap talk sometimes work but other times break down? From there, we transition to Navin's own research, which explores deeper fac
