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 develop a tractable open-economy new-Keynesian model with two sectors to analyze the short-term effects of aid-financed fiscal expansions. We distinguish between spending the aid, which is under the control of the fiscal authorities, and absorbing the aid-using the aid to finance a higher...

We develop a model to analyze the macroeconomic effects of a scaling-up of aid and assess the implications of different policy responses. The model features key structural characteristics of low-income countries, including varying degrees of public investment efficiency and a learning-by-doing...

The Millennium Development Goals (MDGs) represent a global commitment to improve economic and social conditions in low-income countries. Capacity building is key to promoting higher economic growth, which, in turn, is an important prerequisite for making progress toward the MDGs. This paper uses...

This paper surveys the economic literature on the scaling-up of aid to Africa. It provides a checklist of issues that need to be considered when preparing a long term macroeconomic projection for a country involving the assumption of a significant increase in aid. Such scaling-up scenarios are...

We study the role of the exchange rate regime, reserve accumulation, and sterilization policies in the macroeconomics of aid surges. Absent sterilization, a peg allows for almost full aid absorption — an increase in the current account deficit net of aid—delivering the same effects as those...

This paper examines the volume and distribution of concessional and nonconcessional financial flows from Arab countries, and aid agencies, and regional institutions to developing countries. Arab financial assistance increased very rapidly from 1973 to 1980 in line with the rapid growth in oil...

Since the turn of the century, aid flows to Africa have increased on average and become more volatile. As a result, policymakers, particularly in post-stabilization countries where inflation has only recently been brought under control, have been increasingly preoccupied with how best to deploy...
