Course content

The central goal of the seminar is to enable students to create and critique methodologically sophisticated case study research designs in the social sciences. To do so, the seminar will explore the techniques, uses, strengths, and limitations of case study methods, while emphasizing the relationships among these methods, alternative methods, and contemporary debates in the philosophy of science. The research examples used to illustrate methodological issues will be drawn primarily from international relations and comparative politics. The methodological content of the course is also applicable, however, to the study of history, sociology, education, business, economics, and other social and behavioral sciences.

The seminar will begin with a focus on the philosophy of science, theory construction, theory testing, causality, and causal inference. With this epistemological grounding, the seminar will then explore the core issues in case study research design, including methods of structured and focused comparisons of cases, typological theory, case selection, process tracing, and the use of counterfactual analysis. Next, the seminar will look at the epistemological assumptions, comparative strengths and weaknesses, and proper domain of case study methods and alternative methods, particularly statistical methods and formal modeling, and address ways of combining these methods in a single research project. The seminar then examines field research techniques, including archival research and interviews.

Paper Assignments

Option 1

Students have the option of presenting a 3500 - 4000 word case study research design in the final sessions of the course on Friday for constructive critiques by course participants as well as the lecturers. Presumably, students will choose to present the research design for their PhD thesis, though students could also present a research design for a separate project, article, or edited volume. Research designs should address all of the following tasks (elaborated upon in the George-Bennett chapters in the assigned readings below):

  1. specification of the research problem and research objectives, in relation to the current stage of development and research needs of the relevant research program, related litteratures, and alternative explanations;
  2. specification of the independent and dependent variables of the main hypothesis of interest and alternative hypotheses;
  3. selection of a historical case or cases that are appropriate in light of the first two tasks, and justification of why these cases were selected and others were not;
  4. consideration of how variance in the variables can best be described for testing and/or refining existing theories;
  5. specification of the data requirements, including both process tracing data and measurements of the independent and dependent variables for the main hypotheses of interest, including alternative explanations.

For the students presenting their research designs, you do not actually need to prepare a presentation, since we will all read your research designs in advance. You may want to make a few very brief (one or two minutes at most) introductory remarks. These should focus on identifying the issues on which you would really like suggestions or feedback. The rest of the time (we will have about 30 minutes for each research design) will focus on suggestions from the other students and from the faculty member leading the session. During this time you should mostly take notes, and ask clarifying questions as necessary, rather than engaging in defending or discussing your design, as we want to maximize the feedback you get from everyone.

Students interested in presenting their research design on the final day of the course should submit a one-page summary of their research design. The deadline for submitting the summary is 10th of June. This will allow Bennett to provide initial feedback and schedule the research design presentations in the course. 


Option 2

Students also have the option of writing a 3500 to 4000 word essay within eight weeks after the course. However, students are strongly encouraged to present their research design paper on the final Friday of the course, rather than eight weeks after the course, to receive more immediate feedback and to hear feedback from fellow students as well as faculty.

Whether students write a research design for presentation in the final day of the course, or do so within eight weeks after the course, if the paper receives a passing grade the student will receive 8 ECTS.

The lecturer

Andrew Bennett earned his Ph.D. in Public Policy at the Kennedy School of Government at Harvard University in 1990. He has written about case study research methods, military intervention, foreign policy learning, alliance burden sharing, and American foreign policy.  His publications include Condemned to Repetition? The Rise, Fall, and Reprise of Soviet-Russian Military Interventionism 1973-1996 (1999), and, with Alexander L. George, Case Studies and Theory Development in the Social Sciences.

He is President of the Consortium on Qualitative Research Methods, which sponsors an annual two-week institute on qualitative methods at Syracuse University each spring (Google “CQRM” for information on the institute), and a former president of the Qualitative Methods section of the American Political Science Association.  He teaches international relations theory, the U.S. foreign policy process, and qualitative research methods at Georgetown University. Professor Bennett is currently at work on a book examining how members of the Bush Administration, the U.S. Congress, the U.S. Departments of State and Defense, and pundits and academics who supported American intervention in Iraq explain why the intervention did not prove as easy or as successful as they had hoped.
