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 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...

This paper empirically analyzes the impact of aid on education for about 100 countries over the period 1970-2005. We estimate a system of equations to test whether and to what extent the impact of sector-specific aid on educational attainment depends on (i) the extent to which aid adds to...

This paper analyzes whether and to what extent non-governmental organizations (NGOs) outperform official donors by allocating aid in a way that renders effective poverty alleviation more likely. We employ Probit and Tobit models and make use of an exceptionally detailed database that allows an...

Chinese aid comes with few strings attached, allowing recipient country leaders to use it for domestic political purposes. The vulnerability of Chinese aid to political capture has prompted speculation that it may be economically ineffective, or even harmful. We test these claims by estimating...

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...

Bilateral donors use foreign aid to pursue soft power. We test the effectiveness of aid in reaching this goal by leveraging a new dataset on the precise commitment, implementation, and completion dates of Chinese development projects. We use data from the Gallup World Poll for 126 countries over...

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...

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...

NGO aid is still widely believed to be superior to official aid (ODA). However, the incentives of NGOs to excel and target aid to the poor and deserving are increasingly disputed. We contribute to the emerging literature on the allocation of NGO aid by performing panel Tobit estimations for...
