There have been a number of news stories lately that seem straight out of science fiction. We've heard claims before Congress that the government is suppressing information regarding the existence of UFOs or aliens. There are computers that seem to think. And scientists in Korea claimed to have made an extraordinary breakthrough in the hunt for room temperature superconductivity. So how should we think about these things in terms of their potential impact on the economy? In addition to being a Nobel Prize winner and a columnist for the New York Times, economist Paul Krugman is also an avid science fiction fan. In fact, he has credited science fiction for his original interest in economics, even once writing a paper on interstellar trade. He joined us to discuss all of these things, and how to view them through the economics lens.
