Military and Defence Expenditures in the Current Security Context. Concepts and Influencing Factors

In recent years, perhaps more than ever, the world has become increasingly aware of how vulnerable it is to the harsh challenges it must face, sometimes arising out of nowhere or with causes that have spanned years and for which no sustainable solutions have been found. As the most recent challenges come from the security environment and have profound influences on economic and social life, this paper presents relevant aspects concerning the financial efforts of some states to support security and defence and brings attention to a series of factors that can determine the level of military expenditures incurred. To document this work the author has used a series of studies and databases from national and international institutions and organizations in the field, as well as elaborations by researchers recognized for the value and relevance of their opinions expressed in relation to the issues addressed.
