Economic Phenomena before and after War is the result of the author's search for a scientific explanation of modern wars by means of economic statistical data in the statistics of consumption production and natural growth of population.The theory discussed assumes that a state of war in modern communities is dependent on the general economic equilibrium which becomes more and more unstable as industrialization progresses. A state of war indicates a turning point in the action of balancing forces; it moves the economic forces in an opposite direction and is therefore a means for stabilizing the general economic equilibrium.
