This paper shows that donors that maximize relative aid impact spread their budgets across many recipient countries in a unique Nash equilibrium, explaining aid fragmentation. This equilibrium may be inefficient even without fixed costs, and the inefficiency increases in the equality of donors'...

We explore the effect of (big) shocks on the allocation of (bilateral) aid using natural disasters as natural experiments. We find that aid commitment statistically significantly increases following natural disasters, and that humanitarian aid precedes structural aid. While we find that the...

Foreign aid flows to poor, aid-dependent economies are highly volatile and pro-cyclical. Shortfalls in aid coincide with shortfalls in GDP and government revenues. This increases the consumption volatility in aid dependent countries, thereby causing substantial welfare losses. This paper finds...

A dynamic dependent-economy model is developed to investigate the role of the real exchange rate in determining the effects of foreign aid. If capital is perfectly mobile between sectors, untied aid has no longrun impact on the real exchange rate. A decline in the traded sector occurs because...

This paper studies the spending and absorption of aid in PRGF-supported programs, verifies whether the use aid is programmed to be smoothed over time, and analyzes how considerations about macroeconomic stability influence the programmed use of aid. It finds that PRGF-supported programs allow...

We develop a simple macroeconomic model that assesses the effects of higher foreign aid on output growth and other macroeconomic variables, including the real exchange rate. The model is easily tractable and requires estimation of only a few basic parameters. It takes into account the impact of...

This paper builds on the methodology developed by Chudik and Mongardini (2007) to estimate the relationship between grants and remittances and the equilibrium real exchange rate in Sub-Saharan African (SSA) countries using panel techniques. The results indicate that grants and remittances are...

This paper assesses the macroeconomic implications of scaling up aid for Benin in line with the Gleneagles commitment to double aid to poor countries over the next three years to reach 85 per capita by 2010 and keep it at that level thereafter. The analysis suggests that the additional aid...

We analyze the growth impact of official development assistance to developing countries. Our approach is different from that of previous studies in two major ways. First, we disentangle the effects of two kinds of aid: developmental and non-developmental. Second, our specifications allow for the...
