[Compare and contrast the impact of your monetary policies with those of current or historical examples in the United States. What do these examples demonstrate about the validity of macroeconomic models? Be sure to cite your research appropriately.]Inflation fluctuates in the short run, and higher inflation rates typically occur either during or just after economic booms. For example, the biggest spurts of inflation in the US economy during the 20th century followed the wartime booms of World War I and World War II. On the other hand, rates of inflation generally decline during recessions. The AD/AS framework implies two ways that inflationary pressures may arise. One possible trigger is if aggregate demand continues to shift to the right when the economy is already at or near potential GDP and full employment, thus pushing the macroeconomic equilibrium into the steep portion of the aggregate supply curve
