KEYNES, John Maynard. How to Pay for the War. London: Macmillan and Co., 1940. First edition, first issue, 8vo (190 x 120mm.) (Mild toning.) Original blue boards (slight fading, minor dust-soiling.) Note: this is the uncorrected first issue. A corrected version in orange boards was published a few months later. The book presents a Keynesian solution to the economic problem of waging a long war against Germany. The first two chapters are an argument for full employment, the third chapter is a manual on how to achieve that. However, Keynes was aware that even at full employment the output would not be enough unless the population reduced their consumption, accept ‘Deferred Pay’, and accept the diversion of resources towards the war effort.
