In the resulted estimations two possibilities were considered only: the joint program and the national project. In practice of variants it is more: purchases abroad (in the USA) the technics which is in a batch production at which expenses on research and development are not paid; joint release (insignificant participation in expenses on research and development); licence manufacture (specific cost of research and development is included in licence cost), etc. For completeness of the review can be ascertained that economically the most favourable is direct acquisition of finished goods abroad, especially on the basis of the industrial indemnifications which size reaches sometimes 60-80 and 90 100%. Such decision as joint release, considerably concedes by efficiency to purchases abroad. So, acquisition American Ф-16 would manage ' small ' to countries of Western Europe approximately on 25% more cheaply, than manufacture of this fighter on technology of the USA.

One of problems which the West European space business at performance of joint programs faces, the so-called price escalation is. This aspect of space manufacture is not limited to frameworks of international cooperation, and price escalation influence is notable in all spheres of military economy.

Western, in particular French, scientific similar processes in civil high technology branches have been investigated, and received results were unexpected enough: ' quality inflation ' in some branches, such as industrial electronics, instrument making, mechanical engineering, exceeds rates of military inflation, and in separate years an index of both versions ' technical inflation ' below rates of the general inflation. majority of researchers converges that the term ' inflation ' is absolutely not applicable to evolution of the prices for the high technology production, cost of generations of the given kind of the goods following one after another reflecting movement.
