Don Boudreaux has another must-read post with links on the Copenhagen Consensus process that Bjorn Lomborg is heading up. I particularly like his conclusion:
The ultimate goal is to decentralize decision-making power as much as possible down to individuals. It’s at the individual level that cost-benefit calculations are most accurately made; it is at the individual level that the most important “to do” lists are formulated, pursued, adjusted, and achieved.
