The optimum is the best result under given conditions. This also applies to the economics of the state. Economic optimums may exist in multiple formats. In this book, they are limited to those that are relevant to the economics of a country. These are: the optimum of the economic policy, the optimum of production and payments, and the optimum of production and consumption. From these three models, a complex model of the optimum of state economics can be composed. If the optimum is marked as C, and the deviation from the optimum as X, then the value of the non-optimum is (C-X) or C >(C-X). The main task of this optimum is that X becomes zero. Its result is measured by the quotient of optimality, (K). This optimum is achieved when K = (C-X): C = 1. To put this into perspective, the United States represents a quarter of the global economy, but has incurred such a large international debt that it must take the situation very seriously, including the candidates in the next presidential election.
