The International Political Economy Data Resource: Dyadic

Quantitative scholars in international relations and international political economy often draw on the same sources of country-year data across a diverse range of projects. The IPE Data Resource: Dyadic version seeks to provide a public good to the field by standardizing and merging together variables from 27 IPE data sources into a single bilateral (directed-dyad) dataset, increasing efficiency and reducing the risk of data management errors. Easier access to data both encourages researchers to perform more robustness checks than they otherwise might and makes it easier for teachers of quantitative research methods to assign realistic exercises to their students. The unit of analysis in this dataset is the directed dyad-year, with unique observations identified by Gleditsch-Ward number (gwno) and year (Gleditsch and Ward 1999). Countries not present in the Gleditsch-Ward system are excluded from this dataset. This resource will be updated and expanded annually and is available via the Harvard Dataverse Network.
