Foreign aid is almost always in the news, at times more than others. All sorts of questions keep swirling in the air: questions about its nature, rationale, aims, effects, results, justification, symbolism, and even about its quantum. All through this heated debate the issue remains surrounded by a thick fog of obfuscation; many remain unclear of what exactly is being talked about. In this post, I intend to present a primer on foreign aid. Each of the opinions offered in the following sections can be contested; the aim is not to provide a definitive conclusion but to set the stage for an informed debate that employs common definitions and a shared point of departure.
