What determines the foreign aid effort of donor countries? We review the existing literature on donors’ aid budgets and examine which of the suggested variables robustly determine aid effort, measured as Official Development Assistance (ODA) as a share of gross national income. More...

Political proximity between donor and recipient governments may impair the effectiveness of aid by encouraging favoritism. By contrast, political misalignment between donor and recipient governments may render aid less effective by adding to transaction costs and giving rise to incentive...

We investigate the importance of geo-strategic and commercial motives for the allocation of German aid to 138 countries over the 1973-2010 period. We find that geo-strategic and – less robustly – commercial motives matter. When we relate geo-strategic and commercial motives to the political...

We analyze the aid portfolio of various bilateral and multilateral donors, testing whether they have prioritised aid in line with the Millennium Development Goals (MDGs). In doing so, we combine sectorally disaggregated aid data with indicators reflecting the situation of recipient countries...

Using panel data for 143 countries over the period 1973-2002, this paper empirically analyzes the influence of US aid on voting patterns in the UN General Assembly. We use disaggregated aid data to account for the fact that various forms of aid may differ in their ability to induce political...

NGOs play an important role in international development cooperation, but the allocation of NGO aid has rarely been mapped, let alone explained. Based on a representative dataset for 61 important NGOs from various OECD countries, we analyze the targeting of NGO aid across a large number of...

Major DAC donors are widely criticized for weak targeting of aid, selfish aid motives and insufficient coordination. The emergence of an increasing number of new donors may further complicate the coordination of international aid efforts. On the other hand, new donors (many of which were aid...

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...

Using a new dataset for 41 German non-governmental organizations (NGOs), we analyze the allocation of NGO aid across recipient countries in a Tobit regression framework. By identifying for each NGO the degree of public refinancing, we address the largely unresolved issue of whether financial...

Performance-based aid has been proposed as an alternative to the failed traditional approach whereby donors make aid conditional on the reform promises of recipient countries. However, hardly any empirical evidence exists on whether ex post rewards are effective in inducing reforms. We attempt...
