Dr Jason Seawright is Professor of Political Science at Northwestern University. He is the author of three books, Party-System Collapse: The Roots of Crisis in Peru and Venezuela (Stanford, 2012) Multi-Method Social Science: Combining Qualitative and Quantitative Tools (Cambridge, 2016), and Billionaires and Stealth Politics with Benjamin Page and Matthew Lacombe (Chicago, 2018). He has also published in Political Analysis, Sociological Methods and Research, the American Journal of Political Science, Perspectives on Politics, and Comparative Political Studies, among other journals and edited volumes. His research interests include causal inference, mixed-methods research designs, political parties and party systems, populism, and political representation.

Course Content
Can combinations of different methods improve causal inference and related social-science tasks (theory-building, concept formation, description and measurement)? This course will explore mixed-method research designs that strengthen projects relying on many different methodological traditions: various kinds of qualitative research, regression-type statistical studies, experiments, and a range of machine-learning options. We will consider methodological arguments about efficient and less efficient approaches to mixed-method research for each of these combinations, including optimal case selection, assumptions, and other design considerations that maximize the synergy across methods.

Course Objectives
Familiarity with mixed-method research can be useful at the beginning of a scholar’s research trajectory because it can frame design choices and motivate further methodological learning. Alternatively, this course can be valuable at later stages in a career or a given project; mixed-method designs can be added as robustness checks or extensions to existing research, for example. Previous students in this course have published books and articles applying the design ideas we discuss in a wide range of issue areas and across disciplines.

Course Prerequisites
Students should be familiar with core ideas of methodology (such as IVs, DVs, control variables, causal inference, case studies) before taking this course. They should probably have an introductory familiarity with regression analysis and social science statistics, as well.
