The Conference is of the opinion that the economic life of individual countries has definitely ceased to be self-contained; and that, notwithstanding the barriers raised by fiscal duties, it is becoming in ever-increasing measure a part of an economic life in which the whole world participates. 2. It desires that this change be studied with the object of ascertaining to what extent the economic life of individual nations has ceased to be self-contained, and the causes which are bringing about the greater interdependence of nations. 3. Special attention should be paid to the following factors: (_a_) How far the growth of population is responsible for the changes that have occurred and are in progress. (_b_) The extent to which the insufficiency of the natural resources of individual countries for their own requirements has contributed to it. (_c_) Whether the increasing economic unity of the world is the cause or the result of the rising in the standard of living, and how far the increasing welfare of nations has been caused by the growing unity.
