This project-level dataset of multi-bi aid (earmarked voluntary contributions or non-core multilateral aid) to multilateral organizations spans all OECD/DAC donors over the 1990-2012 period. It includes more than 100,000 multi-bi aid activities that are hand-coded for their channel of implementation and earmarking depth.
Access to the dataset may be requested through the Institut für Politikwissenschaft.
