This report the disguise about economic growth in the member countries of the Organization for Economic Co-operation and Development (OCED) is expected to top 4 percent this year. In the developing countries as a group, economic growth is now projected to rise from 1 percent in 1983 to 3.5 percent in 1984. Industrial-country growth in 1984 can be expected to stimulate an increase in developing-country export volumes of about 7.5 percent this year. That, together with a limited amount of net borrowing, will allow imparts to grow by about 6.0 percent this year, thereby providing for some restoration of depleted reserves. This is heartening. But let us not forget that the strength and durability of this trend depends heavily on continued recovery in the industrial nations.
