Sebastian Dellepiane Avellaneda is a Senior Lecturer in Public Policy at the University of Strathclyde in Glasgow, where he teaches political economy and research methods. His research interests include governance and development, policy credibility and economic institutions, the new politics of austerity and economic crises, macro models of party competition, and the role of case studies in comparative research.
Cases studies continue to constitute a large proportion of work generated in the social sciences. Similarly, case study research is increasingly used as a tool for policy analysis. However, the logic and the comparative merits of this approach are often unappreciated. This course stresses the role of case studies in social science methodology and provides an overview of the principles and practices of case-study analysis.
The course consists of ten sessions, each composed of lectures, seminar discussions and group based workshops. We will begin by discussing what a case study is and what it is good for. We will then look at research design, confronting the practical problems of crafting theory-driven and policy-relevant case studies. In the following sessions, we will address the critical issue of case selection and evaluate techniques for choosing cases. After that, we will deal with methods of data collection, including tools for combining qualitative and quantitative sources (e.g. triangulation). The reminder of the course will be dedicated to reviewing approaches for establishing causality (e.g. process tracing, counterfactuals, social experiments) and maximising the leverage of small-n comparisons (e.g. increasing observations, nested analysis, analytic narratives). During this course, students will engage with state-of-the-art applications of case studies drawn from a variety of disciplines and discuss the potential contributions of case study methods to their own research projects.
This course assumes a familiarity with a social science discipline and some basic knowledge of qualitative research methods.

This outline provides an overview of the content of this module. Interactive seminars and group discussions are core components of the course. This means that students are expected to do some intensive reading before seminars. Essential readings are marked with (*) and these are the ones which students should read before each session. At least, you must read one methodological article/chapter and one case study application for each class. You are also strongly encouraged to bring into the discussion issues and examples from your own research agenda. Core readings will be made available through the Summer School office.
