Use a graph of aggregate demand and supply to demonstrate how lags in the policy process can result in undesirable fluctuations in output and inflation.
Go to the St. Louis Federal Reserve FRED database, and find data on the personal consumption expenditure price index (PCECTPI), the unemployment rate (UNRATE), and an estimate of the natural rate of unemployment (NROU). For the price index, adjust the units setting to "Percent Change From Year Ago." For the unemployment rate, adjust the frequency setting to "Quarterly." Select the data from through the most current data available, download the data, and plot all three variables on the same graph. Using your graph, identify periods of demand-pull or costpush movements in the inflation rate. Briefly explain your reasoning.
For aggregate demand shocks and permanent supply shocks, the price stability and economic activity stability objectives are consistent: Stabilizing inflation stabilizes economic activity, even in the short run. For temporary supply shocks, however, there is a trade-off between stabilizing inflation and stabilizing economic activity in the short run. In the long run, however, there is no conflict between stabilizing inflation and stabilizing economic activity.
Suppose three economies are hit with the same temporary negative supply shock. In country A, inflation initially rises and output falls; then inflation rises more and output increases. In country B, inflation initially rises and output falls; then both inflation and output fall. In country C, inflation initially rises and output falls; then inflation falls and output eventually increases. What type of stabilization approach did each country take?
The Problems update with real-time data in MyLab Economics and are available for practice or instructor assignment. 1. On January 19, 2017, the Federal Reserve released its amended statement on longer-run goals and monetary policy strategy. It stated: “The Committee reaffirms its judgment that inflation at the rate of 2 percent, as measured by the annual change in the price index for personal consumption expenditures, is most consistent over the longer run with the Federal Reserve’s statutory mandate” and that “the median of FOMC participants’ estimates of the longer-run normal rate of unemployment was 4.8 percent.” Assume this statement implies that the natural rate of unemployment is believed to be 4.8%. Go to the St. Louis Federal Reserve FRED database, and find data on the personal consumption expenditure price index (PCECTPI), the unemployment rate (UNRATE), real GDP (GDPC1), and real potential gross domestic product (GDPPOT), an estimate of potential GDP. For the price index, adjust the units setting to “Percent Change From Year Ago.” Download the data into a spreadsheet.
