The paper performs aid allocation analysis using OECD-DAC data covering 20 aid donors and 176 recipients over the period 1980-2003. We improve upon earlier work in this area by employing inter alia the variable ‘past outcome’ measuring aid effectiveness in order to link together aid allocation and aid effectiveness. In line with previous work, we also account for both altruistic and selfish donor motives in the empirical analysis. As expected, empirical results based on Tobit estimates of aid allocation for individual donors vary quite significantly among donors. We also test the robustness of our results by estimating individual regressions for the major donors over the period 1990-2003 in view of major events in the aid arena during that time that could potentially have an impact on the aid allocation process. Our results seem to be similar to those derived over the 1980-2003 period, thus implying that this was not the case. Overall, both altruistic and selfish donor motives seem to motivate aid allocation for most donors over the two periods under examination. However, when we further restrict our time dimension to the 1999-2003 period, some important policy changes with regard to selectivity seem to emerge for a small group of donor countries.
