CHAPTER VI CONCLUSIONS AND RECOMMENDATIONS 155. The Group of Experts concludes: (a) That the construction of useful instruments for intertemporal and international comparisons of military expenditures, namely military price indexes and PPPs, IS feasible, given a sufficient availability of relevant statistical information and that good results can be obtained with a relatively limited amount of data, provided that necessary efforts are made to select and collect the information and to make the approprfate comparisons; (b) That military price indexes and PPPs tend usually to be different from ci,vilian or general price Indexes and exchange rates, respectively; (c) That the military measures reflect the real value of military expenditures better than the civilian, and that, therefore, their use is preferable / . . .

analysis: The text appears to be discussing the feasibility and potential benefits of creating standardized tools for comparing military expenditures between countries. It highlights the importance of considering the differences in budgeting and accounting systems, as well as economic development levels, when making these comparisons. The text suggests that this could be useful for international negotiations on reducing military expenditures.
