The Collected Writings of John Maynard Keynes, published in full in electronic and paperback format for the first time, makes available in thirty volumes all of Keynes" published books and articles. This includes writings from his time in the India office and Treasury, correspondence in which he developed his ideas in discussion with fellow economists, and correspondence relating to public affairs. Arguments about Keynes" work have continued long beyond his lifetime, but his ideas remain central to any understanding of modern economics, and a point of departure from which each new generation of economists draws inspiration.
