(b) For PPPs for GDP constructed by the Organisation for Economic Co-operation and Development, see National Accounts, Main Aggregates, 1960-1983, vol. 1 (OECD, Paris, 1984), pp. 123-30. \ . . . A/40/421 English Page 48 121. As for the two types of PPPs, it may, however, be more surprising to find that these two sets of figures show important differences, although these differences remain about the same for all the three years. This should indicate that relative prices of military goods and services and relative weights of subcategories of such items differ largely among countries in a different way than is the case for those prevailing in the civilian sectors of their respective economies. In view of both the special pricing practices with regard to conscripts and of the very special economic conditions in which defence industries are, generally operating, one may not be too surprised to find substantial differences between civilian and military PPPS. If this is generally expected to be the case , which is strongly supported by the results of this exercise, there should be good reason to construct PPPs with specific relevance to military expenditures especially in connection with negotiations to reduce such expenditures, as negotiating Parties would supposedly be concerned with the relative purhcasing power of their military expenditures for which they would want to have accurate information. 122. Based on the military expenditures reported by participating States and on the military PPPs presented in this report, the Group proceeded to recalculate the same military expenditures at international prices, the result of which is shown in table 13. This table shows a comparison among countries of their military expenditures on a disaggregate level which is not possible to find in any other publication. 123. The unit of table 13 is the international dollar, which is defined to have the 
**Analysis**
The text discusses Purchasing Power Parities (PPPs) and their application to military expenditures. It highlights the differences between PPPs for civilian and military sectors, and the importance of constructing PPPs with specific relevance to military expenditures for negotiations to reduce military spending. The text also presents a table showing a comparison of military expenditures among countries at international prices.
