Paul Krugman has finally received his richly-deserved Nobel, which seems an appropriate herald of the end of The Great Unraveling. Officially this was for his work on trade and "spatial economics" (understanding why we have economic "clusters" like Silicon Valley, when economics traditionally thinks of labor and capital as being indifferent to location). Though it also just so happens that his other major area of research and innovation is the understanding of economic crises. He is one of the most important and accessible writers discussing the current financial collapse. If you're interested in understanding what's going on, his blog is required reading.
