Professor Ohlin also made an important contribution to what now might be called the macro-economic aspects of a country's balance of payments. In 1929 in the Economic Journal he engaged in a famous controversy with Keynes on the problem of transferring payments from one country to another across the foreign exchanges. In this he laid stress upon the income-expenditure effects of the reduced spending power in the paying country and of the increased spending power in the recipient country. In doing so he made use of the usual distinction between a country's imports and exports; but in addition he emphasised the importance of the less usual distinction between a country's domestic non-tradeable goods and services and its tradeable, exportable and importable, goods. I made some use of this latter distinction in my Balance of Payments; but looking back I regret that I did not let it play a much more central role in that book

On principle i relative prices will be lowered in the interests of external balance and domestic expenditure will be inflated in the interests of internal balance. Internal balance will be very quickly restored although there is no net change in external balance. Relative prices must, therefore, continue to be lowered, which will tend now to produce a boom at home. The inflationary financial policy must, therefore, be replaced by a deflationary policy. In the end relative prices will be substantially lowered, while there may be a small net inflation or deflation of domestic expenditure by financial policy.

My interest in economics had the following roots. Like many of my generation I considered the heavy unemployment in the United Kingdom in the inter-war period as both stupid and wicked. Moreover, I knew the cure for this evil, because I had become a disciple of the monetary crank, Major , to whose works I had been introduced by a much loved but somewhat eccentric maiden aunt. But my shift to the serious study of economics gradually weakened my belief in Major Douglas's A+B theorem, which was replaced in my thought by the expression MV = PT.
