The United Nations has made a vital contribution to economic intelligence and analysis through the publications of its Bureau of Economic Affairs as well as those of its regional commissions. The prestige of its professional staff is so high that their pronouncements find a respectful audience all over the world. This well-merited recognition, however, burdens the staff with heavy responsibilities. An academic economist may well indulge in political advice or economic forecasting, even though proficiency in economic theory guarantees neither sound political judgment nor the possession of prophetic gifts. It is different with staff members of a public agency, and especially with those of one of the foremost international institutions. Any advice they give should be based on generally accepted theories and values rather than on controversial hypotheses or partisan opinions. And, since they are as unable to foresee the future as other human beings, they should withstand the temptation to make predictions.
