Demand Pull Inflation in the AD\/AS Model<\/h2>\r\n

Inflation fluctuates in the short run. Higher inflation rates have typically occurred either during or just after economic booms: for example, the biggest spurts of inflation in the U.S. economy during the twentieth century followed the wartime booms of World War I and World War II. Conversely, rates of inflation generally decline during recessions. As an extreme example, inflation actually became negative\u2014a situation called \u201cdeflation\u201d\u2014during the Great Depression. Even during the relatively short recession of 1991\u20131992, the rate of inflation declined from 5.4% in 1990 to 3.0% in 1992. During the relatively short recession of 2001, the rate of inflation declined from 3.4% in 2000 to 1.6% in 2002. During the deep recession of 2007\u20132009, the rate of inflation declined from 3.8% in 2008 to \u20130.4% in 2009. Some countries have experienced bouts of high inflation that lasted for years. In the U.S. economy since the mid\u20131980s, inflation does not seem to have had any long-term trend to be substantially higher or lower; instead, it has stayed in the range of 1\u20135% annually.<\/p>\r\n
