<p>This little book packs a big wallop. It puts Krugman s wisdom and steely-eyed analysis firmly at the center of the debate about how to spend upwards of $5 trillion. It may very well change the course of history. Paul Krugman, who writes better than any economist since John Maynard Keynes (Fortune), writes the biweekly Reckonings column for the New York Times. Winner of the John Bates Clark Medal, Krugman teaches at Princeton University.</p>
