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.
Early 1990s recession in the United States
The United States entered recession in 1990, which lasted 8 months through March 1991. Although the recession was mild relative to other post-war recessions, it was characterized by a sluggish employment recovery, most commonly referred to as a jobless recovery. Unemployment continued to rise through June 1992, even though economic growth had returned the previous year.
