Sure, but the award should be rather given to the economists at world bank because they list 'ODA as a percentage of GNI' as as an indicator in their database.
Net ODA received (% of GNI)
Net official development assistance (ODA) consists of disbursements of loans made on concessional terms (net of repayments of principal) and grants by official agencies of the members of the Development Assistance Committee (DAC), by multilateral institutions, and by non-DAC countries to promote economic development and welfare in countries and territories in the DAC list of ODA recipients. It includes loans with a grant element of at least 25 percent (calculated at a rate of discount of 10 percent).
Development Relevance: The ratio of aid to GNI provides a measure of recipient country's dependency on aid.
