We study vote splitting in elections. Vote splitting refers to the phenomenon that the participation of candidates with little chances of winning has the effect of splitting votes away from more popular candidates. We develop a model of an electoral game with two parties, each consisting of one strong candidate and some weak candidates. We analyze strong candidates' incentives to give side transfers to weak candidates to manipulate their campaign participation decisions. We then derive the winning probabilities of the strong candidates in equilibrium.

Global Security: Is Law Our Last Hope?

Join Dr James Manyika, Senior Vice President of Technology and Society at Google, and Philippa Webb, Professor of Public International Law at the Blavatnik School, for a conversation on ‘how to get Artificial Intelligence right’.

They will explore the challenges across the AI pipeline, focusing on implications for human rights, democracy, and public trust. How can humans align with technology that is not limited by human cognition? How can law and policy on AI be anticipatory and not just reactive? How can companies and countries work together on AI’s development and governance?
