The document presents several key graphs that are important for the AP Macroeconomics exam, including:
1) The production possibilities curve shows opportunity cost and inefficiency inside the curve, with efficiency on the curve. The curve shifts right with economic growth.
2) The aggregate demand/aggregate supply model shows equilibrium, recession with a recessionary gap, and inflation beyond full employment with an inflationary gap.
3) The money market graph shows how the Federal Reserve uses monetary policy to shift the money supply curve and change nominal interest rates.
4) The Phillips curve shows the short-run tradeoff between inflation and unemployment, and how it can shift due to supply shocks. In the long-run

20. “Redelsheimer’s Graphs to Know” AP Macro Review Copyright 2010 Phillips Curve Short run trade-off between inflation and unemployment. In the Long Run there is no trade off. The long run Phillips curve is Vertical! Stagflation (an increase in Unemployment and inflation) or an Aggregate Supply Shock will shift the SRPC to the right. Decreases in Inflation and Unemployment will shift the SRPC to the left. (and increase in AS would cause this)
