A generalized approach to international comparison of agricultural output and productivity

This paper utilizes the 12 country data set on agricultural prices and output from a previous ICOP study by Maddison and van Ooststroom (GD-1) to demonstrate the applicability of the Laspeyres, Paasche and Fisher methods along with the Geary Khamis. Analysis in the paper is useful in integrating the techniques used by the ICOP project and the FAO with those of the ICP and Eurostat. The country-product-dummy (CPD) technique is used to fill holes in price data. Sections II and III of the paper provide a simple exposition of the CPD and Geary Khamis methods with a numerical illustration. Detailed tables showing the results from various aggregation methods are included in the paper.
