We use an excludable instrument to test the effect of foreign aid on economic growth in a sample of 96 recipient countries over the 1974-2009 period. We interact donor government fractionalization with a recipient country's probability of receiving aid. The results show that fractionalization...

This study investigates the World Bank's use of lending and non-lending instruments to affect the policy priorities of developing countries. In a typical year, the World Bank lends more than USD 30 billion to its client countries. It also spends approximately USD 200 million on the provision of...
