Ronald Bailey in Reason Online:
Where in the world can we do the most good? Supplying the micronutrients vitamin A and zinc to 80 percent of the 140 million children who lack them in developing countries is ranked as the highest priority by the expert panel at the Copenhagen Consensus 2008 Conference. The cost is $60 million per year, yielding benefits in health and cognitive development of over $1 billion.
Eight leading economists, including five Nobelists, were asked to prioritize 30 different proposed solutions to ten of the world’s biggest problems. The proposed solutions were developed by more than 50 specialist scholars over the past two years and were presented as reports to the panel over the past week. Since we live in a world of scarce resources, not all good projects can be funded. So the experts were constrained in their decision making by allocating a budget of an “extra” $75 billion among the solutions over four years.
Number 2 on the list of Copenhagen Consensus 2008 priorities is to widen free trade by means of the Doha Development Agenda. The benefits from trade are enormous. Success at Doha trade negotiations could boost global income by $3 trillion per year, of which $2.5 trillion would go to the developing countries.
