The SAGE Handbook of Research Methods in Political Science and International Relations offers a comprehensive overview of research processes in social science - from the ideation and design of research projects, through the construction of theoretical arguments, to conceptualization, measurement, and data collection, and quantitative and qualitative empirical analysis - exposited through 65 major new contributions from leading international methodologists. Each chapter surveys, builds upon, and extends the modern state of the art in its area. Following through its six-part organization, undergraduate and graduate students, researchers and practicing academics will be guided through the design, methods, and analysis of issues in Political Science and International Relations: Part One: Formulating Good Research Questions and Designing Good Research Projects; Part Two: Methods of Theoretical Argumentation; Part Three: ...

In Mostly Harmless Econometrics (Angrist and Pischke, 2009) – which has obtained cult-like status in applied empirical economics – the authors recommend the use of diff-in-diff or unit fixed effects approaches to identification, requiring pooled data, if an experiment is infeasible, a meaningful discontinuity, or exogenous variation in the form of an instrument cannot be found.
