Bjorn Lomborg is president of the Copenhagen Consensus Center, a think tank dedicated to applying economic analysis, including cost-benefit analysis, to proposed policies around the issues of the day. He’s also a visiting professor at Copenhagen Business School and visiting fellow at the Hoover Institution at Stanford University. He's the author of many books, including the 2001 bestseller The Skeptical Environmentalist.  His latest book, and the topic for this interview, is Best Things First. Offering cost-benefit analyses of many of the top-line policies of industrial and developing nations, Dr. Lomborg discusses which policies we should prioritize and which we should pay less attention to or end. Lomborg also asserts the benefits of economic growth and says that by spending on technology, we can solve all kinds of big problems, including hunger.
