World War I [SEP] Economic effects
One of the most dramatic effects of the war was the expansion of governmental powers and responsibilities in Britain, France, the United States, and the Dominions of the British Empire. To harness all the power of their societies, governments created new ministries and powers. New taxes were levied and laws enacted, all designed to bolster the war effort; many have lasted to this day. Similarly, the war strained the abilities of some formerly large and bureaucratised governments, such as in Austria-Hungary and Germany. Gross domestic product (GDP) increased for three Allies (Britain, Italy, and the United States), but decreased in France and Russia, in neutral Netherlands, and in the three main Central Powers.
