1. Equilibrium: Real Output (GDP) & the Price Level Chapter 11—one week

2. Review Equilibrium PL and Y are found where the AD and AS curves intersect. Equilibrium PL and Y are found where the AD and AS curves intersect. See skeleton graph See skeleton graph

3. Decreases in AD If AD decreases, recession and cyclical unemployment may result (prices don’t fall easily) If AD decreases, recession and cyclical unemployment may result (prices don’t fall easily) –1. wage contracts are not flexible (or sticky) so businesses cannot afford to reduce prices –2. employers are reluctant to cut wages because of impact of employee effort –3. fear of price wars keep prices from being reduced also

4. Shifting AS Leftward shift in the curve illustrates cost- push inflation Leftward shift in the curve illustrates cost- push inflation Rightward shift in curve will cause a decline in price level Rightward shift in curve will cause a decline in price level

5. Manipulating the AS and AD model Read each scenario. Draw a correctly labeled AD and AS graph to illustrate each short-run impact. You do not need to graph the LRAS at this point. Read each scenario. Draw a correctly labeled AD and AS graph to illustrate each short-run impact. You do not need to graph the LRAS at this point. During a long, slow recovery from a recession, consumers postponed major purchases. Suddenly they begin to buy cars, refrigerators and furnaces to replace their failing models.
