As to the after effects on prices there are likewise only four clear cases. The fall of paper prices relatively to gold after the Napoleonic Wars, and the Civil War was, in each case, clearly due to resumption of specie payments. The fall of prices in the United States after the War of 1812 was doubtless due in large measure to the resumption of foreign trade. In one case there was a rise of prices as an aftermath; the war of 1871, which gave Germany a billion dollars of indemnity, created inflation in Germany and prices rose there between 1871 and 1873 faster than in any other country. This doubtless accentuated the crash in the crisis of 1873.
In the other cases in the diagram the many instances of rise of prices after the wars were due primarily at least, to other causes, although the cessation of war and the undue optimism and spirit of speculation which often follow may, in several instances, have contributed to the boom period and the crisis which so often came a few years later, viz., that of 1857 after the Crimean War, that of 1866 after the Civil War, as well as that of 1873 just mentioned.
The only safe generalizations seem to be the following two: The first is that in so far as a war has been costly, i. e., has strained the economic resources of the belligerents, there has been recourse to inflation in some form and prices have risen. Besides the examples in the chart are those of the French Revolution, the American Colonial wars, the American Revolution and many others. The second generalization is that after a costly war the price level is affected up or down by the fiscal policy of the governments concerned.
HIGH PRICES NOT DUE TO SCARCITY
Most cherish the belief that high war prices today represent war scarcity. In the case of some countries like Belgium and some commodities like paper this is true and in such cases scarcity serves as a partial explanation of high prices. But in the case of most countries and most commodities there has been no general scarcity. The almost universal rise of prices cannot be ascribed to scarcity. Prices have risen of many goods not affected by the war or in countries remotest from the war.
