Economic analysis can be made more complete through the lens of Learning Dynamics. Indeed, it is shown in recent work that Nash Equilibria are incomplete descriptors of game dynamics (Milionis, Papadimitriou, Piliouras, Spendlove, 2023). In this talk we will explore some notable cases where learning dynamics driven by Q-Learning deviate "greatly" from the Equilibrium Behaviour, and in such a manner that it is beneficial for the system welfare. The purpose of this talk is to explore and discover with you which questions to ask when faced with these kinds of dynamics which are interesting in their complexity. I will first present the base model, Q-learners in the Braess Paradox, and explain the ways in which we can create their complex and coordinated behaviour. I will then present an extension of this model with which we can begin to imagine Learning Dynamic Control, in the control theoretic sense of influencing the dynamical behaviour of the multi-agent learning system towards a target behaviour. This work is thus far empirical. I set forth the following question to you: what theoretical questions do you think we can purposefully ask and answer?
