Money and the Balance of Payments [PDF ebook] 

This general introduction to the theory of money and of balance of payments adjustment was originally published in 1969. It was the first book to pay full attention to the theory of assets: the relation of the supply of assets to the demand for holding them and the significance of asset movements for balance of payments adjustment. Written in simple language and with brevity, the book is intended for the student with a general knowledge of economics and economic institutions, but with no specialised knowledge of these topics.
