Bertil Ohlin: Trading

“I am presently at work on a dissertation dealing with the theory of international trade and foreign exchange rates. In dealing with this, studies of the intervention of recent years in the area of trade and exchange rates of different countries is of the greatest importance. I therefore hope to be able to begin a six month study tour to Switzerland, France and England at the end of May this year. After having collected the necessary material I intend — if the economic side can be arranged — during a stay of 6–12 months in England (probably Cambridge) or possibly the United States (in that case probably Harvard University) — to work out the above mentioned dissertation as a specimen for the doctoral degree in philosophy and pursue studies in general. I have not yet any detailed study plan. That should appropriately be set up after the arrival.”

“The origin of this research was an attempt to extend Cassel’s system of equations of price determination in one market to that of several trading countries. Although the point of departure is totally different, the results of that attempt (presented in chapter III) exhibit important similarities to Heckscher’s treatment in ‘‘The Effect of Foreign Trade on the Distribution of Income,’’ published one year earlier in Ekonomisk Tidskrift, 1920. There is no doubt that the author was unconsciously inﬂuenced by Heckscher’s paper both at this and at later stages of the work. The inﬂuence of this pathbreaking paper, both conscious and unconscious, has surely been particularly decisive in the development of the material in chapters I–III.”

“International trade theory has, in my opinion, given far too much attention to the effects of certain variations, for example, in duties, on the national incomes, and too little to the effects on individual incomes. In many cases, changes in the sums count for very little, while changes in the individual incomes are distinctly relevant.”

Change

“I started [in 1921] to write on the foundations of an approach to international trade theory that was to some extent new and for which I received the inspiration during a stroll on [the popular promenade] Unter den Linden in Berlin in 1920.”
