New Publication in the American Journal of Political Science

Philip Leifeld, Professor of Social Statistics at the University of Manchester, together with Laurence Brandenberger, has published a new study in the American Journal of Political Science (2026): Endogenous Coalition Formation in Policy Debates. Abstract Political actors form coalitions around their joint normative beliefs in order to influence the policy process on contentious issues such as climate change or population aging. Policy process theory maintains that learning within and across coalitions is a central predictor of policy change but has yet to explain how policy learning works.
