Marshall is an Assistant Professor in the Columbia University Department of Political Science. His research lies at the intersection of comparative politics and political economy, and spans elections in developing and developed contexts. In particular, he studies how news consumption, (public and private) performance indicators, levels of education, and social networks shape how voters select politicians. As well as bottom-up voter behavior, he is also interested in how politicians communicate their platforms, how information shapes politicians’ electoral strategies, when media outlets choose to report political news, and how institutions can be designed to improve bureaucratic performance. He analyzes these questions by combining quasi-experimental and experimental designs with theoretical models to identify and interpret causal relationships.His research has been published, or is forthcoming, in journals including the American Journal of Political Science, American Political Science Review, Journal of the European Economic Association, Journal of Politics, and Review of Economics and Statistics.
