Krugman has two new posts up today here and here. The first is on state tax data sources, apparently in response to questions about his column from Friday criticizing Schwarzenegger. The second is an excerpt from the Publishers Weekly review of his new book, The Great Unraveling. PK says the book will be in stores September 12 and that he's planning a 14-city tour. When he comes to Boston (and I expect he will) I will be there.
