ECN 206 UAG Economics Aggregate Supply and Demand Discussion

I’m studying for my Economics class and don’t understand how to answer this. Can you help me study? It is important to distinguish  between changes that are anticipated and unanticipated because the  impact on the economy will differ between the two.  The economy is in  long-run equilibrium when the short-run aggregate supply curve,  aggregate demand curve, and long-run aggregate supply curve are in  equilibrium.   What are the major factors  causing a shift in aggregate demand (inward or outward)?  What are the  major factors that will affect short-run aggregate supply?  Long-run  aggregate supply?Review  what factors will lead to a shift in the AD, SAS, and LRAS.  An  increase in output due to economic growth will increase both short-run  and long-run aggregate supply.  Unanticipated changes in either  aggregate demand or aggregate supply will disrupt long-run equilibrium  and cause current output to differ from the economy’s long-run  potential.
