This paper examines several indicators of effective development aid, focusing on the contributions of major bilateral donors. The empirical analyses of selectivity for effective aid delivery revealed that, taking a long-term and regional perspective, some major donors including Japan have been as selective in delivering their aid as some countries well-known for their selective aid delivery, such as Denmark. Japan has provided higher aid for the countries with better policy and governance, and higher grant aid for the countries with lower income, particularly in Sub-Saharan Africa.
