Hidden Games: Exploring the rationality of irrational choices | with Moshe Hoffman
In this episode, we explore the often misunderstood relationship between game theory and human behaviour. Our guest Moshe Hoffman challenges the conventional belief that game theory only applies to rational actors. As Moshe explains in his book “Hidden games” (co-authored with Erez Yoeli), even seemingly irrational behaviours and preferences can be explained through game theory. We dive into the concept of 'hidden games' and their influence on our daily actions and decisions, revealing the subtle complexities of human social behaviour.   Moshe Hoffman is a lecturer at Harvard's Department of Economics and at Boston College as well as an independent scholar.

Truth-telling by design: how Market Design can alleviate inequality | with Piotr Dworczak
In this episode Piotr Dworczak explains to us how Market Design can contribute to alleviating inequality by increasing accuracy of policies targeting inequality. He does so using an example from the housing market which shows that more often than not it is very difficult to ensure that subsidies actually reach people in need since they cannot be easily identified. This is where Market Design comes into play: by generating targeted incentives which have a selection effect, it makes e.g. affordable housing policies more effective.   Piotr Dworczak is associate Professor at the Department of Economics at Northwestern University and Researcher at the Group for Research in Applied Economics (GRAPE) in Warsaw, Poland. He does research on Mechanism and Information Design, specifically with more applied interests in inequality-aware Market Design.
