Recorded live at the CEPR Annual Symposium. We seem to be talking about the behaviour of alpha males on social media a lot recently. But what happens when we put them in charge of a country? The work of Mario Carillo of Universitat Autònoma de Barcelona attempts to answer that question. He talks to Tim Phillips about when and why voters choose alpha males, and how they respond to being given power.
