On the aggregation problem in international comparisons of agricultural production aggregates

Abstract The major aim of this short paper is to provide an original systematic statement of the index number problem involved in obtaining internationally comparable agricultural production aggregates. Alternative output repricing and implicit exchange rates methods are expounded. The standard method of comparison based on wheat-relatives, as used in the work of Hayami and associates, is critically reviewed, and a case is made for the use of alternative procedures.
