A Treatise on Money, completed in 1930, was the outcome of six years of
intensive work and argument with D. H. Robertson, R. G. Hawtrey and
others. As in the Tract on Monetary Reform, the central concerns of the
Treatise are the causes and consequences of changes in the value of
money and the means of controlling such changes to increase well-being.
The analysis is, however, considerably more complex and the applied
statistical work much more elaborate. The Treatise has long been of
interest amongst economists, as a precursor of the General Theory, as an
important discussion of the mechanics of inflationary and deflationary
processes and as an important statement of the problems of national
autonomy in the international economy. This edition provides a new
edition of the original, corrected on the basis of Keynes's
correspondence with other economists and translators. It also provides
the prefaces to foreign editions.
