Foreign policy analysis (FPA) is the study of how states, or the individuals that lead them, make foreign policy, execute foreign policy, and react to the foreign policies of other states. This topical breadth results in a subfield that encompasses a variety of questions and levels of analysis, and a correspondingly diverse set of methodological approaches. There are four methods which have become central in foreign policy analysis: archival research, content analysis, interviews, and focus groups. The first major phase of FPA research is termed “comparative foreign policy.” Proponents of comparative foreign policy sought to achieve comprehensive theories of foreign policy behavior through quantitative analysis of “events” data. An important strand of this behavioral work addressed the relationship between trade dependence and foreign policy compliance. On the other hand, second-generation FPA methodology largely abandoned universalized theory-building in favor of historical methods and qualitative analysis. Second-generation FPA researchers place particular emphasis on developing case study methodologies driven by social science principles. Meanwhile, the third-generation of FPA scholarship combines innovative quantitative and qualitative methods. Several methods of foreign policy analysis used by third-generation FPA researchers include computer assisted coding, experiments, simulation, surveys, network analysis, and prediction markets. Ultimately, additional attention should be given to determining the degree to which current methods of foreign policy analysis allow predictive or prescriptive conclusions. FPA scholars should also focus more in reengaging foreign policy analysis with the core of international relations research.
