The United Nations’ Millennium Development Goals have cautiously been hailed a success with several being met ahead of target. Now the United Nations is working on a set of “Sustainable Development Goals” and one economist analyzed the goals that will likely lead to the most development:

• Air pollution kills 7 million people a year. Changing how people cook would save lives and generate $10 for every dollar spent.
• Activists could also try to upgrade people to more high tech stoves that generate less smoke but that would create only $2 of value for every dollar spent.
• The most beneficial policy would be to reduce barriers to trade. According to one estimate this would generate $3,426 for developing countries, for every $1 spent.
• Other ideas that would generate high returns per dollar include providing reproductive-health services ($120), increasing nursery school enrollment ($33), and broadband penetration ($17).
• Some argue that the UN should focus on “data for development” but the act of monitoring is expensive and will take away the money available for actual development.
