In the economy shown above, initially long-run eggregate supply is LRAS 0, short-run aggregate supply is SAS0, and aggregate demand is AD. Then some events change aggregate supply, and the aggregate supply curves shift rightward to LAS1 and SAS1. In addition, potential GDP changed from GDPFo to GDPF1. A. What is the equilibrium point after the change in aggregate supply? Ans: B. What events could hav changed long-run aggregate supply from LRAS0 to LRAS1 ? Ans: C. What events could have changed short-run aggregate supply from SAS0 to SAS1 ? Ans: D. After the increase in aggregate supply, is real GDP greater than or less than potential GDP? Ans: In the irt-run aggregate suppiy is SAso, and aggregate demand is AU. I nen some events change aggregate supply, and the aggregate supply curves shift rightward to LAS1 and SASL. In addition, potential GDP changed from GDPFo to GDPF1. A. What is the equilibrium point after the change in aggregate supply? Ans: B. What events could have changed long-run aggregate supply from LRASn to LRAS
