The economic content of security, i.e. to what extent security is influenced by economic variables, is a difficult and widely debated one. There has been a tendency, to broaden the concept of security to include certain purely economic interests. The paper is concerned with a precise understanding of the difference between a narrow and territorial definition of security, and a broader definition of security encompassing economic interests. The first section defines security and its economic ramifications and the second discusses the subject within the context of a general equilibrium model. The policy dilemmas of security are then considered at the conceptual level, including the dilemmas in the general equilibrium model.
