The economics of the Star Trek universe were discussed at New York Comic Con on Sunday. Paul Krugman was among the panelists who debated whether a world without money could actually work. CNN reports: "Star Trek has dared to 'boldly go where no man has gone before' — including a world without money. 'One of the things that's interesting about Star Trek is that it does try to imagine a post-scarcity economy where there's no money. People don't work for it. People don't work because they have to but because they want to,' said Annalee Newitz, the editor of Gawker's io9 blog. Newitz -- along with Nobel Prize winner and economist Paul Krugman, 'Treknomics' author Manu Saadia, economics professor Brad DeLong, Fusion's Felix Salmon and Star Trek writer Chris Black -- discussed economics through the lens of the Star Trek world at a New York Comic Con panel Sunday."
