Fixing the World, Bang-for-the-Buck Edition (Rebroadcast)

The episode examines cost-benefit analysis in global development, using economist Bjorn Lomborg's work with the Copenhagen Consensus Center to compare the ROI of interventions like malaria prevention versus HIV treatment. It argues that funding often follows emotional appeal rather than effectiveness, and presents data showing malaria prevention saves lives at one-tenth the cost of HIV treatment. The framework prioritizes spending based on measurable impact per dollar across health, education, and climate.

To understand how cost-benefit analysis can redirect aid spending toward interventions with the highest measurable impact per dollar.

1. 01Malaria prevention costs about $1,000 per life saved, while HIV treatment costs $10,000 per life, suggesting a tenfold difference in effectiveness.
2. 02Funding decisions in global development are often driven by media attention and emotional narratives rather than measurable impact.
3. 03The Copenhagen Consensus ranks interventions by cost-effectiveness, advocating for economists to guide aid spending over politically motivated choices.
