Now is perhaps a good moment to point out that in addition to the papers that I have looked at in this series, Copenhagen Consensus 2012 commissioned other research papers to provide a range of opinions. For each of the topics that we have looked at, there are two “Perspective Papers,” also written by experts in the field, who question the assumptions, methodology, and conclusions of the research that you’ve been reading about. So the Nobel-laureate expert panel members (who, after a year of looking at drafts of these research papers, are now in a closed-door meeting to come up with their own views about which investments should be prioritized), are hearing a range of expert opinions.
