I've talked before about efficient giving, and now there's a Slate article on the best use for a dollar. (via Marginal Revolution). More interesting is the Copenhagen Consensus, where a group of economists attempted to rank proposed solutions to the world's greatest problems according to cost/benefit ratio. Their highest ranked category contained:
- Fighting HIV/AIDS
- Providing micronutrients to reduce malnutrition
- Free Trade
- Fighting Malaria
Note that 2 of these 4 (AIDS/Malaria) were among my suggestions for where money spent could have the greatest utilitarian impact. And unsurprisingly for economists, global warming proposals were ranked dead last.
