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.
Effects of the Great Recession
The crisis affected all countries in some ways, but certain countries were vastly affected more than others. By measuring currency devaluation, equity market decline, and the rise in sovereign bond spreads, a picture of financial devastation emerges. Since these three indicators show financial weakness, taken together, they capture the impact of the crisis. The Carnegie Endowment for International Peace reports in its International Economics Bulletin that Ukraine, as well as Argentina and Jamaica, are the countries most deeply affected by the crisis. Other severely affected countries are Ireland, Russia, Mexico, Hungary, the Baltic states, United States and United Kingdom. By contrast, China, Japan, Brazil, India, Iran, Peru and Australia are "among the least affected."
