Net Aid Transfers data set (1960–2015)
The Net Aid Transfers (NAT) variable alters two aspects of the standard Net Overseas Development Assistance (Net ODA) measure that can be problematic for aid research and donor evaluation. First, where Net ODA is a capital flow concept, analogous to Net Foreign Direct Investment, NAT is a net transfers concept. That is, Net ODA is net only of principle payments received on ODA loans, not of interest received on such loans, while NAT is net of both. Second, NAT excludes cancellation of old non-ODA loans.
