The typical identification strategy in aid effectiveness studies assumes donor motives do not influence the impact of aid on growth. We call this homogeneity assumption into question, first constructing a model in which donor motives matter and then testing the assumption empirically.

The effects of development aid have been extensively discussed, and the extent to which aid has been effective in achieving its goals is widely disputed. At the same time, several studies and theorists point towards the unintended and potentially negative effects of aid. This working paper gives...

It is widely believed that the Millennium Challenge Corporation (MCC) has grossly fallen short of high expectations raised by the Bush administration in 2002. From the perspective of potential recipient countries, the crucial issue is whether the MCC increased the overall pool of aid resources...

This paper reviews what has been learned over many decades of foreign aid to education. It discusses what works and what does not and in this discussion draws attention to the fact that even a simple assessment requires more than providing a uniform check-list of inputs. It shows the positive...

This paper examines whether the federal structure of aid-receiving countries matters in explaining aid effectiveness. Following the decentralization theorem, the devolution of powers should increase aid effectiveness, since local decision-makers are better informed about local needs. At the same...

The paper reviews the evidence of the impact of trade liberalisation on the economic performance of poor developing countries with respect to poverty reduction, the distribution of income within countries, the distribution of income between countries, trade and the balance of payments, and...

Advanced OECD countries are widely held responsible to contain global carbon emissions by providing financial and technical support to developing economies, where emissions are increasing most rapidly. It is open to question, however, whether more generous official development assistance would...

It is widely believed that the Millennium Challenge Corporation (MCC) has grossly fallen short of high expectations raised by the Bush administration in 2002. From the perspective of potential recipient countries, the crucial issue is whether the MCC increased the overall pool of aid resources...

We assess empirically whether foreign official development assistance (ODA) has been effective in alleviating HIV/AIDS epidemics, which figures prominently among the Millennium Development Goals. We employ a difference-in-difference-in-differences approach to identify the treatment effect of ODA...

This paper examines the long-run effect of foreign aid on income inequality for 21 recipient countries using panel cointegration techniques to control for omitted variable and endogeneity bias. We find that aid exerts an inequality increasing effect on income distribution.
