private guilds, which in turn assume costs for these damages. However, generally these have not been quantified, because of the difficulty they have to be directly calculated. This tends to present itself as a generalized problem in quantifying the costs associated with conflict. This is explained, in part, by the tendency in the various economic sectors not to denounce this type of actions that, in one way or another, interrupt the normal functioning of economic activities. The costs of kidnaps and extortions Colombia is the country in which more people are and have been kidnapped. Kidnapping, as one of the manifestations that underlie the armed conflict, carries both direct and indirect costs. The former comprise mainly the payment of ransoms and the expenses assumed by the State to control and prevent it. Indirect costs include, "[...] the loss of human capital for the duration of the detention and for the death of the kidnapped during his captivity". There are two types of kidnapping: a) kidnapping for extortion and political purposes; and b) simple kidnapping. According to data from the Directorate of Justice and Security of the DNP, this phenomenon shows an increasing trend. With respect to the costs of sequestration, the sources suggest an increasing behavior between 1996 and 2003. In such a way that "the average annual growth rate is 9.3%, the highest rate is observed in 1998 (46.2%), and in 2000 (37.2%) year in which the number of kidnappings also it is significantly high [...] reaching its peak in the year 2000 with 1,938 cases." From then on, the trend becomes decreasing (except for a peak in 2002 with 1,542 cases) until reaching the 350 kidnappings (the lowest figure since 1996) in 2005. Within these costs, 64.4% are direct, representing US$167.4 million. 35.6% of the remaining costs are indirect, and represent US$92.7 million. In 2004, the costs of sequestration were reduced to $109,519 million, representing 0.27% of GDP in 2003. Costs of Defense and National Security While spending on defense and security becomes very important to examine when dealing with a country immersed in an armed conflict, the analysis on this issue are relatively recent. This can be explained because until the beginning of the second half of the nineties, defense and security spending had a significant growth. Spending on defense and security includes, on the one hand, the means by which the State must have to defend
