text: Sample Of participants includes four members of the same military alliance and all eight participants are developed market economies. 137. To summarize this chapter, the Group is pleased to present the results it has achieved but feels that there would still be room for those results to be improved if more time and efforts had been or could be devoted to deal with the above-mentioned problems and difficulties. Although the results of this exercise in terms Of military price indexes and PPPs could be improved, they are, nevertheless, in the Group's opinion much better to use for the comparison Of participating States' military expenditures than general civilian price indexes and official exchange rates. The Group wants also to underline that another important reSUlt of this exercise is the experience and knowledge which have been gained through it and which should - in spite of the limitations imposed by the small number of participating States - prove to be useful in the event of future international negotiations on agreements to reduce military expenditures. CHAPTER V THE USEFULNESS OF THIS AND EARLIER STUDIES FOR FUTURE NEGOTIATIONS ON AGREEMENTS TO REDUCE MILITARY EXPENDITURES 138. As has been stated in detail in the introduction, this Group's report belongs to a series of united Nationsreports prepared by successive groups of experts to facilitate agreements on a reduction of military expenditures which would result, inter alia, in a release of resources that could be used for economic and social development, particularly for the benefit of the developing countries. 139. The Group believes that it is useful at this time to briefly review how the pres,ent study, as well as the entire series of studies , contributes to the reaching of such agreements and to consider what additional issues might deserve to be examined.
