Deflation
Deflation occurred periodically in the U.S. during the 19th century (the most important exception was during the Civil War). This deflation was at times caused by technological progress that created significant economic growth, but at other times it was triggered by financial crises — notably the Panic of 1837 which caused deflation through 1844, and the Panic of 1873 which triggered the Long Depression that lasted until 1879. These deflationary periods preceded the establishment of the U.S. Federal Reserve System and its active management of monetary matters. Episodes of deflation have been rare and brief since the Federal Reserve was created (a notable exception being the Great Depression) while U.S. economic progress has been unprecedented.

"Recent Economic Changes and Their Effect on the Production and Distribution of Wealth and Well-Being of Society" (1891) is a frequently cited reference for U.S. economic history of the late 19th century and is available in modern reprints. It is an account of the dramatic changes in the world economy transitioning into the Second Industrial Revolution in which Wells documented many of the changes in trade, such as triple expansion steam shipping, railroads, the effect of the international telegraph network and the opening of the Suez Canal. Wells also discussed the Long Depression and many causes of the great advances in productivity of the preceding 20 years. Wells noted that many of the government inquires on the “depression of prices” (deflation) found various reasons such as the scarcity of gold and silver. Wells showed that the U.S money supply, especially the amount of gold and silver, actually rose significantly during the deflation. Wells pointed out that deflation only lowered the cost of goods that benefited from improved methods of manufacturing and transportation. Goods produced by craftsmen did not decrease in value, nor did many services, and the cost of labor actually increased. Also, deflation did not occur in countries that did not have modern manufacturing, transportation and communications.
